The latest course of High-yield cultivation techniques of Pueraria lobata

Pueraria lobata, also known as Pueraria lobata, is a vine of Pueraria Leguminosae, which has high edible value, economic value and medical and health care value, and its planting benefit is extremely high. At present, its development and utilization is a hot spot at home and abroad. What if the high yield can only be obtained when planting? Let's have a look with the editor.

1. Land selection and preparation

In order to obtain high yield, the humus soil or sandy loam with loose and fertile soil, deep soil layer and good drainage is needed first. The pH value is between 6 and 8, and the planting land is close to the water source, the light is sufficient, and it should be far away from the industrial pollution area. After selecting the planting land, we should prepare the soil as soon as possible, turn the soil to weathering, improve the soil fertility, and then dig the planting ditch according to the topography, requiring the ditch to be 50-60 cm deep and wide. When preparing the land, we should remove the residual plants of weeds, catch and kill pests and reduce insect pests. As the growth cycle of Pueraria lobata is relatively long, it can only be harvested after planting for 2-3 years, so it is necessary to apply sufficient base fertilizer, generally applying 4000-5000 per mu of rotten organic fertilizer, 15-20 kg of ternary compound fertilizer and 10-20 kg of phosphate fertilizer. Apply it into the planting ditch, backfill the topsoil 20-30 cm thick, and mix the fertilizer and soil evenly.

2. Select improved varieties

When planting, the improved varieties must be selected according to the local soil, climate and use, so as to improve the yield and processing purpose. For example, if it is used to make kudzu powder, we should choose varieties with starch content and Oh, ah, and if it is used for medicinal purposes, as the raw material of medicine, we should choose varieties with higher flavonoid content. Choose different varieties for different uses, so as to maximize the benefits.

3. Field management

Pueraria lobata is a kind of fertilizer-tolerant plant, which needs to be fertilized many times during the whole growth period. the first time when the seedlings grow to 25-30 cm, 3-5 kg of manure water is applied to each plant, and then applied every 30-45 days, according to the actual situation of the plant. The sprouting power of Pueraria lobata is very strong. When the seedling grows to 15-20 cm, it is necessary to leave 1-2 strong seedlings in each hole. When combined with the first fertilization, it is necessary to set up and introduce vines to increase the permeability between plants. When the seedling grows to 2 meters, it is necessary to pick the heart in time to promote its multi-branching and enhance photosynthesis, while when there are too many leaves, it will affect photosynthesis and consume a lot of nutrition, so it is necessary to pick leaves in time, which is conducive to root growth and expansion and increase yield.

4. Diseases and insect pests

Diseases and insect pests are also one of the yield factors that harm Pueraria lobata. The common diseases are yellow powder, root rot, heart borer, locusts, aphids and so on. The prevention and control of diseases and insect pests should give priority to prevention and comprehensive control, and the methods of rotation, soil disinfection, weeding, pruning and pruning, and increasing fertilizer should be adopted to promote the growth and strength of Pueraria lobata, increase its disease resistance and stress resistance, and reduce diseases and insect pests. For the prevention and control of diseases and insect pests must be timely, after the discovery of diseases and insect pests should be timely spraying drug control.

The above is the introduction of high-yield cultivation techniques of Pueraria lobata. I hope it can help you. If you want to know more about it, please follow us.
