How to manage peas in spring? Detailed explanation of the latest key points

Peas are a cool-loving long-day crop, generally grown overwinter in the Yangtze River basin. Under the warm spring climate and the nourishment of spring rain, they begin to turn green again, which is also a critical period for their vegetative growth and reproductive growth, and is extremely important for a bumper pea harvest. So how should peas be managed in spring? Let's take a look.

1. Cold protection

Although peas are cold-tolerant, they grow vigorously after turning green again, and although spring temperatures are gradually rising, the temperature is unstable. Fluctuating temperatures will cause great harm to their normal growth, and thus to pea yield, so attention should be paid to cold protection measures. Before a cold wave arrives, peas can be sprayed with a 800-fold dilution of high-fat film, which can effectively keep them warm and protect against cold.

2. Fertilizer and water management

Peas have a well-developed root system and many root nodules. They have a very strong nitrogen-fixing capacity themselves, so their demand for nitrogen is not high. However, during the flowering and podding stage, peas need a great deal of fertilizer, and at this time the nitrogen-fixing capacity of the roots cannot meet their needs, so at this time an appropriate amount of nitrogen fertilizer and phosphate fertilizer should still be maintained to encourage the plants to flower and set pods more. Peas have a very strong drought tolerance, but they dislike waterlogging, so water management should focus on doing a good job of drainage, especially during continuous spring rain, when drainage should be done frequently to prevent the plants from lodging.

3. Promoting flowers and strengthening pods

This is the foundation for abundant flowers and strong pods, so after peas enter normal growth from the turning-green stage, a flower-promoting fertilizer should be sprayed immediately, which can effectively improve the normal growth condition of the plants, inhibit spring shoot growth, and promote flowering and strong flowers. In addition, in order to improve pollen fertilization quality, increase the fruit-setting rate, and promote fruit development, vegetable-fruit stem-strengthening agent should be sprayed at the budding stage, once every 10-15 days, for 2-3 times, with an obvious yield-increasing effect.

4. Pest and disease control
