How to manage peas in spring? Keep these key points in mind

Peas are a long-day crop that prefers cool conditions. They are generally grown overwinter in the Yangtze River basin, and under the warm spring climate and nourishment of spring rain, they begin to turn green again. This is also a critical period for their vegetative growth and reproductive growth, and it is extremely important for a high pea yield. 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, they are 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 preserve heat 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 ability 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 ability of the roots cannot meet their needs, so a moderate amount of nitrogen fertilizer and phosphorus fertilizer should be maintained at this time to encourage the plants to bloom and set pods more. Peas have extremely strong drought tolerance, but they are sensitive to waterlogging, so water management should focus mainly on drainage, especially during continuous spring rain, when drainage should be frequent to prevent the plants from lodging.

3. Promote flowering and strengthen pods

This is the foundation for abundant flowers and strong pods, so after peas enter normal growth from the greening stage, a flowering-promoting fertilizer should be sprayed immediately once, 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 bud stage, once every 10-15 days, for 2-3 times, with an obvious yield-increasing effect.

4. Pest and disease control

Common diseases of peas in spring include anthracnose, blight, and rust. Anthracnose and blight can be controlled with Junbike plus Xin'gaozhimo, while rust can be controlled with Fenxiuling and Xin'gaozhimo; the main pest is aphids, which can be controlled with imidacloprid and imidacloprid.
