Planting techniques and requirements of bean king

Jadouwang is suitable for planting in loose and fertile soil with good drainage, and basic fertilizer can be applied with chemical fertilizer and farm manure, soaking and disinfecting seeds before planting, and then sowing seeds according to row spacing 40cm, plant spacing 30cm and the density of 3 seeds per hole. Control water and fertilizer in the seedling stage, fertilize and water once in the vine stage with ploughing, fertilize in the flowering and fruiting stage combined with irrigation, use bamboo pole to draw the vine, and do a good job in pest control during the period.

First, prepare the land and make beds.

When planting the king of beans, we should choose to plant in the well-drained, loose and fertile soil. Before soil preparation, we need to apply basic fertilizer, which can be applied with fully mature farm fertilizer and a small amount of chemical fertilizer, and then plough the soil to level the border. According to the width of the border is 1.2m, the height of the border is 6cm, and the distance between the borders is 70cm.

II. Planting specifications

First of all, soak the seeds in a diluted germicidal solution for 2-3 hours, which is beneficial to kill the residual germs, then clean them with clean water and sow them. Generally, each row can be sowed with two rows, according to the row spacing for 40cm, the plant spacing for 30cm, and 3 seeds per hole. If the sowing temperature is relatively low, the film can be covered for heat preservation.

Fertilizing and irrigating

The main results are as follows: 1. In the seedling growth stage, if there is too much fertilizer and water, it is easy to rot the root, so it is necessary to control water and fertilizer in the seedling stage, and it can cooperate with intertillage fertilization and watering once in the seedling stage. it is beneficial to promote the growth of vines and flower bud differentiation.

2. When King Douwang enters the flowering and fruiting stage, sufficient water and nutrients are needed. Usually at this stage, fertilization can be carried out combined with irrigation, while after flowering, the required nutrients will be consumed very quickly.

3. Therefore, in order to keep the soil moist at this stage, we also need to apply less nitrogen fertilizer, or we can choose to spray iron, zinc and other trace elements to supplement the nutrients needed on the leaf surface in time, and if the plant does not senescence early, we can properly apply fertilizer 1-2 times, which is beneficial to promote the plant to blossom, prolong the harvest time and increase its yield.

Fourth, build a bracket

When the king of beans begins to shake off the vine, the bamboo pole can be used to build the frame, and the bamboo pole can build an adult shape, and cooperate with the support to draw the vine to promote the vine to grow upward.

V. Prevention and control of diseases and insect pests

In the whole growth stage, the main diseases and insect pests are leaf mite, rust, gray mold, root rot, bean pod borer and so on. During this period, timely spraying can prevent the spread of diseases and insect pests, and it is also necessary to control them during the period of high incidence of diseases and insect pests, so as to improve the quality and yield of King Douwang.
