Is Nanchong Suitable for Planting Golden Silk Huang Ju? It is said that it costs 3 yuan a flower, and the poor one costs 30 cents.
This paper mainly describes the planting method and field management of golden chrysanthemum.
First, the planting method of golden chrysanthemum
1. Chrysanthemum planting site selection and soil preparation are not strict with soil requirements. It is best to grow in soil with good drainage, fertile and loose soil and rich fertility. Land, low-irrigated land and saline-alkali land are not suitable for planting, and continuous cropping is prohibited.
2. Propagation methods The propagation methods include close planting and cutting propagation.
(1) After collecting chrysanthemums in June, 5438+0 1, select plants with strong growth and no pests and diseases, dig out all the roots, remove the aboveground parts, plant them on fertile plots, and apply a layer of soil miscellaneous fertilizer to keep warm for the winter. Dig up the soil and water it in March-April. In April-May, the seedlings of Portuguese flowers will grow to 6544. Digging pits is planted in the ground, and each pit has 1-2 plants. After planting, the soil is covered and compacted, and every 667 square meters of old seedlings can be planted 1 hectare of production field.
(2) In April-May or June-August, select new branches that are robust and free from pests and diseases as cuttings. Take the middle section, cut it into short sections of 10- 15 meters, treat the cuttings with plant hormones, then insert them into the seedbed according to the row spacing of 20-25 cm and the plant spacing of 6-7 cm, compact and water for about 20 days to take root, then apply human and animal manure every 1 month, and move the seedlings out of the circle when they are 20 cm high.
(3) Transplanting branch seedlings from April to May, and cutting seedlings from May to June. Choose cloudy day after rain or tomorrow night. On the whole surface, according to the plant spacing of 40 cm per plant, after the section, cover the soil and tamp it, and set up coarse water.
3. After strong flowering branches, when the face height is 25 cm, 1-2 cm should be removed, and then once every half month, and harmful root separation, box height disease, code disease and so on should be carried out after high temperature in summer. 5. Treating grape flowers from harmful habitats usually has a high incidence in rainy season. Timely drainage.
Northeast China is not suitable for planting. Overwintering will freeze the old seedlings to death and need replanting. It can be planted in some areas of Gansu.
Field management in Jin Ju
1, intertillage weeding
Intertillage and weeding should be strengthened during the growth period of golden chrysanthemum planted in the open field. Generally, intertillage weeding should be carried out five times a year, once each from May to September. According to the weeding principle of "early weeding, small weeding", weeds should not affect the growth of Jin Huang Ju plants. Because the root system of chrysanthemum is shallow, the intertillage should be shallow to avoid damaging the root system. If the root system is exposed, the soil should be cultivated in time to prevent lodging. When transplanting wild chrysanthemum with plastic film, weeds under the stump should be pulled out, weeds in the ditch should be removed with herbicides, and the weather forecast should be paid attention to to to ensure that it will not rain within 3 days after applying herbicides.
2. Water management
Golden silk chrysanthemum should avoid water accumulation. If there is too much rain in summer to form water, it is easy to rot and die. Therefore, it is necessary to strengthen drainage management before and after every rain, and carefully check to ensure smooth drainage. In case of drought in flowering period, water it in time.
3, timely topdressing
Golden chrysanthemums like fertilizers and grow strongly on fertile land. Therefore, topdressing should be carried out according to different growth stages under the condition of applying sufficient base fertilizer. Planting in the open field, the first topdressing is carried out after pruning, and 25 kilograms of human and animal manure 1500 kg or 45% potassium sulfate compound fertilizer is applied per mu, and 0.2% ~ 0.3% of "Banidabika potassium dihydrogen phosphate" solution is sprayed on the leaves during the second germination period. For chrysanthemum fields with sufficient base fertilizer and transplanted with plastic film, no branch fertilizer can be applied, but if there is a lack of fertilizer in the later stage, 25 kg of "Banida Bika Compound Fertilizer" should be applied in the ridge and ditch in the middle and late August. The application of nitrogen fertilizer should be less, otherwise the dry flower rate will be low and the quality of chrysanthemum will be poor.
Step 4 cut the seedlings
In the middle and late May, choose sunny or cloudy days to cut the seedlings once, leaving the seedlings 2 ~ 3 cm high from the ground. In the future, 3 ~ 5 strong branches will be kept and the other weak branches will be erased, which will help to ensure the flowering time and chrysanthemum quality.
5. Scaffolding
After cutting seedlings, the plants have many branches and large flowers, and the flowers are concentrated at the top of the plants. Plants are prone to lodging when it rains. Therefore, scaffolding should be set up on the border to prevent lodging.
Step 6 harvest
The flowering time is long, but the gathering time is concentrated, mainly in the first ten days of 1 1. When the flowers are in full bloom for 3/4, they should be harvested after the dew dries in the sunny morning. After harvesting, it should be treated in time to prevent the flowers from rotting and discoloring.
