Interplanting technology of pea

Peas are common legume vegetables, which can be interplanted with many crops in production, not only peas, but also can eliminate and prevent some diseases and insect pests, but also increase soil fertility and improve light and utilization rate. it can also play the effect of shading and controlling weeds. As long as intercropping crops adapt to each other and promote each other, they can be intercropped together. Next, let's take a look at the benefits of pea intercropping and how to do it.

1. Interplanting peas with corn

First sow peas in the field, plant them in strips, and leave corn rows in the middle and gaps on both sides. Generally, about three rows of peas are planted, and then two rows of corn are set aside for planting. First sow peas, wait until peas emerge, gradually grow to about 30 centimeters when you can build a frame, you can sow corn. Corn can be jointed and grown tall soon after emergence, and generally do not restrict each other. Peas will blossom and bear fruit immediately, while corn is still in the vegetative growth period, nutritional needs do not conflict, can be replenished until the pea pods, corn can block part of the bright light for it to avoid loss of water during the day. After the pea is harvested, the corn enters the flowering stage, and the residual pea plants can be dried and turned into the ground as fertilizer for corn.

2. Interplanting tobacco with peas

After the leaves in the middle of the base of flue-cured tobacco are harvested, you can begin to sow peas, and the tobacco itself stays wide because of the length of the leaves. In addition, after the bottom picking, there is enough space between the rows to sow directly between the rows. When the pea emerges, the upper leaves can maintain a warm and humid environment for the pea seedling stage. When it grows to build a fight, the tobacco leaf buds are almost harvested, and this is the peak period of pea growth, so they will not compete with him for nutritional water and can accept enough light to grow normally. And the tobacco stalk can be used to build a net, which can save manpower and material resources.

3. Interplanting and fertilization

Peas apply basic fertilizer and use mild farm manure, about 300 jin per mu, and you can also add some compound fertilizer. Fertilizer can be diluted after adding water, because the pea root system is mainly whisker root, the root system is not strong, to avoid root damage. After setting up the frame, after topdressing, the topdressing mainly applies compound fertilizer directly on the surface without covering the soil. In addition, foliar fertilizer is sprayed to supplement potassium and boron. Trace elements such as molybdenum. Corn base fertilizer is mainly applied about 50 jin of compound chemical fertilizer, 50 jin of plant ash and 100 jin of human and animal fertilizer. Urea was applied to promote the bud at the fruiting stage. Tobacco fertilizer can be fertilized as usual, but it can be applied more base fertilizer during soil preparation, which can last longer, and it is not convenient to apply pea fertilizer in the middle. After that, you can apply fertilizer to yourself.

Pea can be interplanted with a variety of crops to maximize the use of land resources and create more economic benefits, but the contradiction between the two must be minimized. This is the best way and main purpose of efficient pea interplanting.
