Cultivation techniques of Zizania latifolia

Polygonatum odoratum is generally propagated by rhizomes, and the propagation speed is very fast. Mangroves grow one node a year, which can be used to judge the growth period. Each node can grow 2 ~ 3 branches and 6 ~ 9 branches in 2 years. Choose the stout branches of the year, with neat buds and slightly concave inward. Small, thin branches and old branches with sharp buds protruding outward cannot germinate, so it is not suitable to keep seeds, otherwise, the nutrition is insufficient, the vitality is not strong, the offspring are affected, the quality is poor and the yield is low. It is also not suitable to use the main stem to keep seeds, because the main stem is big and long, and the cost is too high. Removing the main stem will seriously affect the quality of the product and it is not easy to sell.

In addition, don't use bamboo roots and bamboo tails as cultivation seeds, but use pig manure tails as cultivation seeds. Polygonatum odoratum likes humid and cool climate and is suitable for growing in slightly acidic yellow sand soil. Good color, loose sand, high yield, not easy to break after mining. The underground stems of Polygonatum odoratum grow around and are not easy to loosen, so it is not suitable for cultivation in clay. The color of black soil products is not good, which affects the quality.

Polygonatum odoratum is usually cultivated in August, which is not suitable for continuous cropping and planting after pepper stubble. Otherwise, the root system will grow poorly, the yield will be low, the quality will be poor, and even the seedlings will die. Generally, Polygonatum odoratum has the best harvest in 2 ~ 3 years, so it is planted once every 3 years. harvest

The planting of Polygonatum odoratum can be harvested 1 year, but the yield is low and the size can not meet the specifications. 2 ~ 3 years old Polygonatum odoratum has the best harvest, high yield and good quality. The output is higher in 4 years, but the quality is decreased, the cellulose is increased and the effective components are decreased.

The harvest season is usually in early August. When harvesting, first cut off the aboveground stems with a sickle, and then dig from front to back with a hoe (preferably a two-toothed hoe), which can reduce the damage of underground stems. Leave roots in time after digging out, and then remove the soil and remaining stems on the ground. If the soil is dry and hardened, the soil should be removed with tools such as bamboo sticks, and the branches should not be connected together, but each Polygonatum odoratum stick should be kept as long as possible to reduce bending.

process

(1) Dry the blank. Put the harvested jade on a clean cement floor to dry. The drying time depends on the intensity of the scene, the accumulation thickness of Polygonatum odoratum and the irradiation time. It usually takes 2 to 4 days to dry until it becomes soft and wrinkles begin to appear. Too long drying time will make the strips of Polygonatum odoratum wrinkled and not full, which will affect the quality. But if the sun is wrong, the sugar juice can't be kneaded. In case of rain, move to a ventilated and dry place to prevent moisture and mildew and deterioration of the injured part.

② removing fibrous roots

Polygonatum odoratum has many fibrous roots, which are easily broken and removed after drying. If the amount of Polygonatum odoratum is small, it can be packed in a fiber bag, rubbed by hand, stepped on by foot, or shaken back and forth with bamboo baskets and baskets, and removed mechanically when the amount of Polygonatum odoratum is large. Sometimes if you can't clean it once, you have to go for the second time until it's finished.

③ Knead sugar juice.

Use a kneader to knead Polygonatum odoratum into a transparent and sticky state. If the kneading is not good, the dried strips of Polygonatum odoratum will be wrinkled and not full, and the color of Polygonatum odoratum will not be white, which will affect the quality. If you knead too much, too much sugar juice will be lost, and the strips of Polygonatum odoratum are easy to stick to dust, with thick color, which is not easy to dry and will also affect the quality. The kneading time varies according to the degree of sunlight, kneading method and operating temperature.

④ Drying sliver

After the sugar juice is kneaded, it should be spread out and dried in time, and it should not be delayed, piled together or soaked in the rain. If you don't pay attention, it will be covered with white mold and black mold overnight, and the product will be scrapped. If the weather is bad, don't rub the sugar juice in a hurry Be sure to wait until it clears up. If it rains after wiping, it should be quickly placed in a ventilated and dry place and blown by a hair dryer or electric fan. In case of continuous rainy weather, it should be baked in the curing barn. The site for drying Polygonatum odoratum strips must be clean and flat. Polygonatum odoratum strips must be thoroughly dried. Otherwise, it is easy to be moldy and deteriorated when bagged and put into storage.

Polygonatum odoratum strips are usually packaged in one package, and some of them are divided into two grades. Good requirements are thick, full and wrinkle-free, brown (or brown) in color, fresh and bright, 65,438+00 cm in length and 65,438+0 cm in diameter, and the rest are equal to the external grade. Generally processed into strips of Polygonatum odoratum, it can be sold.

⑤ planing and slicing

Jade and bamboo chips can only be planed vertically, not horizontally or obliquely. To plan very thin, the thickness is required to be below 0. 1 cm.

A small amount of Polygonatum odoratum can be planed by hand and needs a special plane. Slice a large number of Polygonatum odoratum with a slicer.

Sliced Polygonatum odoratum should also be dried in time, otherwise it will be moldy or not white. Generally, it can be dried on the same day. Don't fly a plane if the weather is bad.

⑥ Film selection and packaging.

After drying the jade bamboo chips in the sun, they are classified, selected and packaged. Generally divided into two levels. Good is called film selection, which requires white color, borderless skin and a length of more than 7 cm. The poor ones are called uniform films, that is, those with edge skins and short and narrow carpels. Some are divided into three grades, and then the best ones, which are 15 cm long and 10 cm wide, are called pendants, and they should be arranged neatly one by one when packaging. The number of packages depends on the size of the package, but it is not easy to be too big.

Product quality: the finished product is dry enough, peeled and turned into a square block with uniform thickness, with high white quality.

Prevention and control methods:

(1) can be sprayed with 0. 1 ~ 0.2 Baume lime-sulfur mixture or 20% triadimefon 2000 times solution for control.

(2) Seeding under disease-free conditions or finding diseased plants for clearing (a small number of diseased plants). This is a fungal disease that mainly damages leaves. At first, an oval or irregular lesion with purple-red edge and brown middle appeared from the tip of the blade, and the lesion gradually spread downward, making the leaves pale, withered and died. Most cases begin in summer and autumn, and the onset is more serious in rainy season.

Prevention and control methods:

(1) Clean up the sanitation in the garden in time after harvest, focus on burning dead branches and diseases, and eliminate overwintering germs in the garden;

② Chemical control: spray 1: 120 bordeaux solution or 50% bacitracin solution 0/000 times of/kloc-0 every 0/0 day for 2-3 consecutive times. This is a fungal disease that mainly damages leaves. The lesion is round to oval on both sides of the leaf, 2-5 mm in diameter, red at first, gray to grayish brown in the back center, with black spots on it, which is the conidia of the pathogen.

Prevention and control methods:

(1) After harvesting, thoroughly clean the garden, remove diseased leaves in time, and bury them deeply or burn them.

② At the initial stage of the disease, 50% zineb 600-fold solution, 70% thiophanate-methyl 800- 1000-fold solution or 50% Wanmeiling 500-fold solution were selected and sprayed every 15 days, 2-3 times in a row.

Brown spot is a fungal disease, which mainly harms leaves. The damaged leaves produce brown spots, which are often limited by veins, strip-shaped, light in the center, and gray-black mildew in the later stage. It often leads to premature withering of leaves and affects yield. Too much nitrogen fertilizer, too dense plants and high humidity in the field are all conducive to the disease.

Prevention and control methods:

(1) Thoroughly clean the sick and disabled in the field after autumn, and bury or burn them in a centralized way; Spraying 250 times of copper sulfate solution on the ground before emergence in spring.

(2) Strengthen cultivation management, implement formula fertilization, and avoid overgrowth of plants.

③ At the initial stage of the disease, cut off the diseased part in time and protect it with 1: 1: 150 bordeaux solution; In the growing season, 600 times solution of 50% mancozeb, 800 times solution of 70% thiophanate-methyl or 500 times solution of 50% wanjunling are used alternately and sprayed for 2-3 times. Prevention and control methods:

① Check wintering sites in winter and spring to eliminate adults;

(2) using adult suspended animation to kill people;

③ Avoid the neighboring potato fields;

④ Chemical control: spray with 90% trichlorfon crystal or 50% acetaminophen EC 1000 times. abstract
