How to grow bamboo I want to grow a small piece at home.

It's good to grow bamboo at home. Phyllostachys pubescens can be planted all year round, but it is not cold-resistant, so it can't be planted outdoors in northern areas.

mao bamboo

Phyllostachys pubescens is a grassy bamboo plant. Young stems are dark green, slightly whitish, and turn olive yellow when they are old. Type ⅱ: normal cylindrical, 7- 10 m high, internodes 30-35 cm; Deformed culms are usually 25-50 cm, and the internodes are shorter than normal. Ligule leaves ovate-lanceolate; Sheath glabrous; Ligule developed, round or oval to sickle-shaped; Tongue is very short. Sexual preference is warm, moist and not cold-resistant. It should grow in fertile, loose, moist and well-drained sandy loam. It is distributed at home and abroad. This species is often potted and cultivated by artificial topping to form deformed plants for viewing; Planted on the ground, it forms tall bamboo bushes, and occasionally a few deformed poles grow in normal poles. The beautiful Buddha's belly bamboo is also the processing object of many handicrafts and thousands of articles. Such as fans, bamboo carvings, musical instruments and so on.

There are also short air roots on the first and second segments of the base;

This species is often potted and cultivated by artificial top cutting, forming deformed plants for viewing; Planted on the ground, it forms tall bamboo bushes, and occasionally a few deformed poles grow in normal poles.

After referring to the main type specimens of the big stomach king. Nana, Wen Taihui 8550 1 (Holotyp. , ZJFI), confirm that it is exactly the same as B. ventricosa McClure, and the distinguishing features emphasized in its description are also the same as those mentioned by F. A. McClure in the original description, so it should be merged.

Type II: The normal pole is 8 8- 10/0m high and 3-5cm in diameter, with the tail tip slightly bent downwards and the lower part slightly zigzag; The internodes are cylindrical, 30-35 cm long, with no gray powder when they are young, smooth and hairless, and the lower part is slightly swollen; A circle of gray silk hairs is formed on the lower nodes of the rod above and below the reed ring, and short air roots are also formed on the first and second nodes of the base; Branches often start from the third and fourth nodes at the base of the stem, and each node has 1-3 branches. Branches on its branches are sometimes shortened into soft spines, and many branches are clustered on the middle and upper nodes of the stem, among which 3 branches are relatively thick and long.

The deformed rod is usually 25-50 cm high, with a diameter of 1-2 cm, short internodes, enlarged base, bottle-shaped and 2-3 cm long. A circle of gray silk wool belt is formed on each node of the lower part of the pole above and below the reed ring; Branching habits are slightly higher, often single-branched, spineless, with shorter internodes and obvious expansion. The sheath falls off early, and the back is completely hairless. When it is dry, the longitudinal ribs are obviously raised, and the top is nearly symmetrical and wide arch or nearly truncated. Unequal ears, curved edges? Hair, big ears narrowly ovate to ovate-lanceolate, 5-6 mm wide, small ears ovate, 3-5 mm wide; The ligule is 0.5- 1 mm high, and the edge is covered with extremely short thin fringed hairs; The flap is erect or abduction, easy to fall off, ovate to ovate-lanceolate, slightly heart-shaped at the base and slightly narrower than the sheath tip. Leaf sheaths glabrous; Auricles ovate or sickle-shaped, with several waves at the edge? Hair; Ligule is very short, sub-truncated, with very short cilia at the edge; Leaf blade is linear-lanceolate to lanceolate, 9-18cm long and1-2cm wide. The upper surface is hairless, the lower surface is densely pubescent, with a drill-like tip at the top and a nearly round or wide wedge-shaped base.

Pseudospikelets are solitary or clustered, linear-lanceolate, slightly flat and 3-4 cm long; The first leaf is broadly ovoid, 2.5-3 mm long, with 2 ridges, covered with short fibers and blunt apex; Bud 1 or 2, narrowly ovoid, about 4-5 mm long, 13- 15 veined, with acute apex; Flowering period: May-July flowering, July-September fruiting. Spikelets contain 6-8 bisexual florets, including 1 or 2 at the base and 2 or 3 at the terminal, which are often sterile; The internode of spikelet axis is flat, 2-3 mm long, with cup-shaped tip and short fiber covering the edge. The glume is usually oval, 6.5-8 mm long, with veins 1 5-17 and sharp tip.

2 growth habit editor

Water-resistant, moisture-resistant and light-loving plants. Likes humid and warm humid climate, and has low cold resistance, and can tolerate light frost and extreme low temperature around 0℃, but plants suffer from cold damage when they are exposed to long-term low temperature of 4~6℃. The tropical area south of the Tropic of Cancer can safely overwinter in the open field, and the northern part of South China can still be cultivated in the leeward and sunny places. From Central China to North China, only potted plants, greenhouses or indoors are suitable for cold protection. I like light, but I also tolerate damp. For fertile and moist acidic soil, it is quite resistant to water and drought, and it is suitable to keep the soil moist often when planted in the ground or potted plants. Calcium, magnesium, phosphorus or decomposed livestock manure should be applied as base fertilizer, and nitrogen fertilizer should be applied once a month or every other month at the peak of growth to keep the Huang Liang of stems and leaves green, but it is not advisable to apply too much nitrogen fertilizer to avoid the excessive growth of each node, forming a Buddha's belly shape and reducing the ornamental value.

Garden use

Phyllostachys pubescens is shrub-like, with short and deformed stems, like Buddha's abdomen, beautiful posture and green seasons. The pots of plants that were modeled in those days were scattered into a jungle bamboo-belly style, decorated with stones, and the ornamental effect was quite good. Indoor potted plants. Leaf-watching tree species, with peculiar stem shapes, are simple and elegant, forming a unique landscape in the garden. Suitable for planting in courtyards, parks, waterfront areas, etc. And with rockeries, cliffs and other configurations, it is more elegant. Su Dongpo has poems such as "Eating without meat is better than living without bamboo" and "Being without bamboo is vulgar". The ancients called it "plum, orchid, bamboo and chrysanthemum", and bamboo played an important role in gardens. Due to the great difference of temperature in different places, the types of bamboo suitable for cultivation are different. Phyllostachys pubescens is the leading ornamental bamboo with high ornamental value. It is suitable for both open planting and potted display. Also cultivated in the same genus are jade with yellow stems and green stripes; Phyllostachys pubescens, with large bamboo shape, short nodes and obvious swelling between nodes.

Breeding mode

The method of ramet propagation was adopted. Dig some plants in autumn and plant them separately. In the north, potted plants can only be planted in greenhouses or planting tanks. For example, all kinds of bamboos are planted in rows, and brick partition walls should be made in the planting tanks to prevent underground stems from colluding with mixed planting. Phyllostachys pubescens should be replaced with soil and planted separately in February every year. Choose slightly acidic soil, and it is best to mix loose sapropelic soil and fertile mineral soil. When changing soil, old soil and old soil should be part of the root carving, so that new roots can grow easily. Planting should choose shallow pots, control the growth of roots, and let the unearthed bamboo shoots grow up slowly and thicken horizontally. In summer, the rainwater is evenly mixed, and the water of potted bamboo adapts. Most of the unearthed bamboo shoots are short in section and large in abdomen. In late autumn, the weather is dry, bamboo pots are short of water, and bamboo shoots are long and flat. The overwintering temperature shall not be lower than 5℃. In order to keep the basin soil relatively moist, leaves are often sprayed with clear water. Apply decomposed liquid fertilizer and phosphorus and potassium fertilizer every half month during the growth period to promote the bamboo shoots to be strong and the Buddha's belly to be shaped.

By branching or cutting propagation, new and old plants are clustered, and the temperature rises from March to May every year. Before the new bamboo shoots germinate, the tender stems of 1~2 years old in large clumps are cut off from the base and soaked in water for 1 day and night, so that the bamboo stems can absorb enough water, and most of the leaves are cut off, and they can survive after planting, and they can watch the germination in the same year or the next year. Cutting was carried out in the middle and late March of spring, with tender bamboo stalks of 1~2 years old as cuttings, and inserted on the stout main lateral branches or secondary branches, with 3 node buds per panicle, leaves were cut off from the upper part or a few leaves, and nodes were inserted into the wet sand bed. It can take root in about 1 month, and can be transplanted into nursery for cultivation in about 2 months, and can be planted in pots or in the open field for 3-4 years in the following year. After 1 seedling, more seedlings can be produced, and a few seedlings are left each time, which can germinate into new clumps in the next year or be planted in the nursery.

Preparatory work/about to start work

1. Preparation of substrate: The substrate of Phyllostachys pubescens is sandy loam rich in humus, and the commonly used substrates are: (1) sandy loam.

(adding proper amount of decomposed base fertilizer); (2) peat mud (burning soil)+farmland topsoil (1:1); (3) Farmland topsoil+river sand+proper amount of decomposed base fertilizer (4: 2: 1).

2. Packaging of seedling bag: sterilize the prepared substrate with phoxim and Geotrichum candidum powder, then put it into a seedling bag of 8cmx 12cm, and arrange it neatly for later use (it is advisable that the substrate in the bag is full at nine minutes after water seepage).

Collect seed branches

Selecte mother bamboo born more than 2 year, stripping bamboo branches with air roots on that moth bamboo from the roots of the base, and the picked mother bamboo can still be used for greening or technology. Pay attention to keep the bamboo branch base intact without cracking, and keep the air root intact. Cut off the bamboo branches with leaves, leaving only about 20cm above the base, soak the collected bamboo branches in clean water for 24 hours, and then take them out and clean them for cutting (note: do not soak them in chlorine-containing tap water). [5]

Cutting under seed

Cut the soaked seed branches into seedling bags with a depth of 5cm. Water after cutting and cover with 75% shading net.

Seedling management

This method can be implemented in spring, summer, autumn and winter, but in winter and spring, the plastic film should be covered to ensure that the temperature is above 65438 08℃ and the humidity is above 80%, and the substrate in the seedling bag should be kept moist. Water is poured three times a day in the morning, middle and evening in summer and autumn, and new roots (developed from air roots) can germinate after about 25-30 days. At this time, you can apply a lightly decomposed organic fertilizer. After that, apply fertilizer every 25 days (N:K= 1: 1). When the roots grow seedling bags, seedlings can emerge after pumping leaves twice, but there should be a seedling hardening period of about 10 days before emergence (gradually reduce the number of shading and watering until full illumination). When bamboo shoots just emerge from the soil, watering should be controlled to inhibit their growth. When the pot soil is dry and the bamboo leaves wilt slightly, water can be sprayed on the leaves for about 1 hour, and then the leaves are permeable and repeated several times. When the bamboo shoots grow to about 40 cm, the bamboo joints are basically formed, and normal watering can be resumed.

Peeling: When the bamboo shoots grow to 25 cm high, peel 1-2 at the base, and peel 1 every week thereafter. Stripping bamboo shoots can make lateral branches grow, promote bamboo shoots to be dwarfed, and make internodes shorter and thicker.

Directions: When the bamboo grows to a certain height, cut off the top of the bamboo shoot by 5-6 cm to make the top and lateral branches of the plant grow. When the lateral branches reach a certain length, they should also be pointed.

control of insect

Common diseases are rust and moles.

Prevention and control methods: rust is sprayed with 50% Wei Xiuling wettable powder 2000 times, and nevus is sprayed with 50% thiophanate-methyl wettable powder 500 times.

The pests prone to occur are scale insects and bamboo locusts.

Control methods of scale insects:

1. Spraying Mirex and adding proper amount of kerosene in nymph stage can seal suffocation.

2. Spray an aqueous solution of washing powder. The method is as follows: firstly, the washing powder is dissolved in water according to the ratio of 65,438+0: 65,438+000, evenly stirred and left standing for 6 hours, then 40% omethoate EC or dichlorvos emulsion is added, diluted by 65,438+0: 65,438+0,500 times, and sprayed in time for 2-3 times. After spraying for 2-3 days, rinse the whole plant with clear water.

You can also use 60-degree white wine, according to the ratio of 1:2, when the scale insects start to move in spring. Watering four tablets 1 time, then every 15 days/time, and continuous watering for 8-9 times can achieve the control effect. For other methods, please refer to the pest control part of Cycas.

Control method of bamboo locust: spray 90% trichlorfon 1500 times solution.
