The latest spring management tips for peas

Pea is a cold and cool long-day crop, which is generally cultivated in the Yangtze River valley. Under the warm spring climate and spring rain, pea begins to turn green, which is also a key period for its vegetative growth and reproductive growth. It is very important for high yield of pea. So how to manage peas in spring? Let's take a look.

1. Guard against cold

Although the pea is hardy, it grows vigorously after turning green, and although the temperature in spring is gradually rising, the temperature is unstable. Temperature fluctuations will cause great harm to its normal growth, thus the yield of peas, so we should pay attention to cold prevention measures. Peas can be sprayed with 800-fold liquid of high-fat film before the cold wave comes, which can effectively keep warm and prevent cold.

2. Fertilizer and water management

The root system of pea is well developed and there are many nodules. It has a very strong nitrogen fixation, so the demand for nitrogen is not high. However, the pea needs a large amount of fertilizer at the flowering and pod stage, and the nitrogen fixation capacity of the root system can not meet its needs, so it is necessary to maintain an appropriate amount of nitrogen and phosphorus fertilizer to promote the plant to blossom and bear pods. The drought tolerance of pea is very strong, but avoid waterlogging, so water management is mainly to do a good job of drainage, especially in the continuous loss of spring rain, drainage should be diligent to avoid plant lodging.

3. Promoting flowers and strong pods

Flower propagation and pod strong foundation, so after the pea from the green period to the normal growth, we should immediately spray a flower-promoting fertilizer, which can effectively improve the normal growth of the plant, inhibit the growth of spring shoots, and promote its flowering. In addition, in order to improve the quality of pollen insemination, increase the fruit setting rate and promote fruit development, vegetable fruit Zhuangtieling should be sprayed at the budding stage, once every 10-15 days, leaving 2-3 times.

4. Pest control

The common diseases of pea in spring are anthracnose, blight, rust and so on. Anthracnose and blight can be controlled by Shibike plus new high-fat membrane, while rust can be controlled by powder rust and new high-fat membrane, and insect pests are mainly aphids. Imidacloprid and imidacloprid can be used to control.
