Planting method of burdock

Burdock, also known as Dalizi, root vegetable, is rich in crude fiber, protein and a variety of nutrients, its root system can also be used as medicine, is a vegetable for both medicine and food, and is deeply loved by people. So do you know how to grow burdock? Let's take a look at its planting method with the editor.

1. Land selection and preparation

Burdock likes sufficient light, warm and humid environment, more heat and cold resistance, suitable for growing in fertile soil with deep soil layer and good drainage, and the soil rich in organic matter is the most ideal. Burdock avoid continuous cropping, the previous crop had better be rape, broad bean and other crops, before planting combined with land preparation per mu of farm fertilizer 3000-4000 kg, calcium superphosphate 50 and the right amount of compound fertilizer. Put the combined cultivated land into the soil, and then rake it fine and level it out.

2. Sowing seeds

Burdock generally uses the method of seed reproduction, choose full particles, disease-free planting, soak it in warm water for a day, put it warm and rinse once a day, until the seeds are white and sow. There are hole sowing and strip sowing methods. Strip sowing can open a shallow trench with a depth of 2-3cm according to the row spacing 60cm, and spread the seeds evenly into the ditch and cover the soil. On the other hand, hole sowing should be dug according to the row spacing of 30 × 60cm, generally sowing about 5 seeds in each hole, slightly suppressing the covering soil after sowing, and moisturizing the covered soil.

3. Field management

After the seeds emerge, the cover grass should be removed in cloudy days or in the evening, but when the seedlings grow to 2-3 leaves, there should be time seedlings, one seedling should be planted according to the plant spacing of 4-5, and 2 seedlings should be left in each hole, and there is a surplus for transplanting or pulling out. When the seedlings grow to 4-5 leaves, the seedlings should be fixed in time, one plant should be kept according to the distance between plants in strip sowing and one in each hole according to 30cm. If the burdock grows slowly, if there are more weeds, it will affect the growth and even lead to death, so intertillage weeding is very important, the whole growth period should be ploughed and weeded 4-5 times.

4. Fertilizer and water management

Fertilization is essential for burdock to grow rapidly. In April of the second year after sowing, 1000 kg of farm manure and 15 kg of diammonium phosphate should be applied per mu, spread on the ground, combined with mid-tillage and turned into the soil. Spraying potassium dihydrogen phosphate foliar fertilizer per mu at flowering stage can promote flowering and fruiting. It should be watered in time during drought and drained in time in the rainy season, so as not to cause rotting roots due to excessive stagnant water.
