Management of the latest podding period of pea

The peak growth period of pea planting is the podding period of pea, when sufficient fertilizer and water are needed, pruning and other measures are needed to regulate the growth of pea. So what measures are generally used to assist regulation, and how should fertilizer and water be managed? Pay attention to the following.

First, pruning

1. Debudding

The lateral buds at the base can be removed in order to ventilate and penetrate light, increase light and function, reduce canopy, reduce humidity, and avoid diseases caused by lower branches touching the ground. It can also avoid unnecessary nutrition consumption, supply nutrients to you in the main branch, and then make the main branch thicker and pod.

two。 Pick the heart

Set aside the main vine and several lateral vines, and then remove most of the parts, removing the terminal buds from both the main vine and the lateral vine. Eliminate the top advantage, preserve nutrition to thicken the branches, do not need to grow, so as not to consume too many nutrients to reduce the quality of pods.

Second, lighting

When planting peas in the greenhouse, the time of receiving light can be adjusted. Generally, when peas bear pods, the requirements of light time are not too strict, and they can grow well without adjustment in the open field. But pea pods, afraid of strong light, need sunlight, strong light will make peas lose water, so they can cover the sun in strong light weather.

Third, fertilizer and water

Pea root is not strong, need water, but can not accumulate water, generally is to keep dry and wet, pod period to apply more fertilizer and water. But do not flood irrigation, apply too much fertilizer at one time, you can apply it many times in this period. Podding fertilizer is the most important topdressing at this stage. After the young pods are settled, fertilizers and water are applied together, about 100 jin of compound fertilizer is applied per mu, and watered a week later to promote dissolution and absorption. Water once a week and fertilize every one and a half months until there are no more pods, but topdressing can prolong the growth period of peas.

IV. Prevention and control of diseases and insect pests

The main disease of pea is brown spot, which mainly harms leaves, stems and pods, showing brown ring spots and withered leaves. It is usually induced by low temperature. Spray 70% methyl topiramate wettable powder 500 times at the initial stage of the disease, once a week for several weeks. The main pest is Liriomyza nigra, mainly the larvae eat the xylem in the stem, mainly harm legumes, use or 45% phoxim EC to spray 1000 times of water.

Pea podding period is mainly to achieve the above work, we must pay attention to these key points. Through the above simple introduction, you should know some content, more other content can pay attention to follow-up updates.
