Burdock is a food and vegetable used for both medicine and food. It is also called fertility and root vegetables. Fresh burdock is rich in crude fiber, protein, calcium, iron, carotene and vitamins. It has high edible value and is very popular among consumers. Let's take a look at the cultivation techniques and management methods of burdock.
1. Site selection
Choose loam or sandy loam where the terrain is sunny, the soil is deep, the soil is fertile, and the drainage is good. Avoid continuous cropping, the former sputum is suitable for cereals, rapeseed, broad beans and other crops. Acre with farmer's fertilizer 3000-4000kg, superphosphate 50kg, urea 5kg (conditional can + compound fertilizer) as the base fertilizer, the fertilizer will be evenly applied to the surface before the cultivated land, combined with the cultivated land once into the soil, the depth of cultivated land is more than 30cm , 耙 flat and fine.
2, seeding management
Seeds are used to breed, and seeds that are full, disease-free, and non-invasive are selected. After soaking the seeds in warm water for 24 hours, put them in a warm place and rinse them once with warm water for 1 day until the seeds are white. Sowing in the Ching Ming Festival (from early April to late April). There are two kinds of seeding methods: striping and hole sowing. The seeding can be ditched by a row spacing of 60cm, the depth of the ditch is 2-3cm, the seeds are evenly spread in the ditch, covering the soil 1-2cm; the hole sowing can be planted according to the row spacing of 30cm×60cm, 4-6 grains per hole, 2-3cm covering soil . After the sowing, it is necessary to slightly suppress the seeds so that the seeds are in close contact with the soil, and the grass is kept moist. The amount of seed per acre is generally 0.5-0.75kg.
3. Field management
After emergence, remove the cover grass in the evening or cloudy days. When the seedlings grow 2-3 pieces of true leaf time seedlings, the seeding field is 1-5cm long and strong seedlings, and the hole sowing field leaves 2 strong seedlings per hole. The seedlings were all removed. When the seedlings grow 4-5 pieces of true leaves, the seedlings are planted, the seeding field is 1 plant with a plant spacing of 25-30 cm, and 1 seedling is planted at each hole. If the cavity is properly replenished.
4, cultivating weeding
In combination with interplanting seedlings for weeding and weeding, the growth of burdock plants is slow. Many weeds in the seedling stage are most afraid of “grass eating seedlingsâ€. Weeding and weeding should be carried out in time until the plants are out of action, and the whole growth period is 4-5 times, and the roots are cultivated at the same time. Eli breathable and protect the roots. When cultivating soil, note that the growth point cannot be buried in the soil.
5, topdressing management
In the second year of planting in the second year of planting, 1000kg of high-quality farmyard manure and 15kg of diammonium phosphate were applied per mu, evenly spread on the surface, combined with weeding and turned into the soil. Foliar fertilizer such as potassium dihydrogen phosphate 0.2-0.3kg+ (èŠ¸è–¹ç´ +碧护) is sprayed on the alternate foliage of each acre to promote flowering results. In the same year, the burdock did not produce the results. In order to promote the growth, seedling growth and yield and quality in the second year, the leaves and weeds should be removed in time after the winter leaves withered. The frozen water should be sealed during the drought and the soil at the base of the plants before the freezing. After 2 years of thawing, the soil will be loosened.
6. Pest control
The main pests and diseases of Burdock are leaf spot and powdery mildew, angular spot disease, and are prone to occur during high temperature and rainy periods, mainly affecting leaves. In the field, the diseased leaves were removed and burned in time; the initial surface of the disease was sprayed with 50% thiophanate or 20% triadimefon or 12% myclobutanil, and the amount of mu was 0.1-0.15kg, once every 7-10 days, even sprayed 2-3 times.
The above is about the introduction of the method of growing burdock. The burdock is a vegetable with high economic efficiency. The market prospect is good. If you have conditions, you can consider planting. Regarding the burdock, what else do you want to add?
