Snow pea cultivation is a good planting project, but the cultivation technology of snow peas is not complicated. Spring sowing is mainly used in the Huanghuai River Basin. Other areas should be determined according to local geographical and climatic conditions. Planting time. The snow pea planting technology and management methods are introduced as follows: 1. How to prepare the land and fertilize before planting snow peas

After the harvest of cotton, rice, sweet potatoes and other late crops, the stubble should be cleared and the land prepared in time. When preparing the land, apply 3,000 kilograms of organic fertilizer, 10 kilograms of urea, 50 kilograms of superphosphate, and 15 to 20 kilograms of potassium sulfate at one time per acre. If there is plant ash, you can apply some more plant ash.

After the land is prepared, make a 2-meter-wide east-west border with a border height of 25 cm and a width of 20 cm. 2. Sowing and methods of snow peas

When sowing, you can choose dwarf varieties with large pods such as Kingfisher peas. These varieties generally have pods of 12 to 16 cm long and are very popular in the market. popular.

The suitable sowing period in the Huanghuai River Basin is generally from October 25th to November 5th. If the sowing date is too early, the seedlings will easily grow leggy and suffer from frost damage years ago. In the Jianghuai region where temperatures are higher in winter, the sowing date can be postponed to mid-to-late November.

If the moisture is not good during sowing, water should be added along with the holes. However, avoid watering heavily after sowing and before emergence, so as not to affect the emergence of seedlings.

When sowing, you can plant in large and small rows, with large rows of 60 cm and small rows of 40 cm. The spacing between plants is 20 to 50 cm, and 2 to 3 seeds are planted in each hole. After sowing, cover with 2 to 3 cm of soil. 3. Field management techniques for snow pea planting

Before winter, the seedlings are creeping and can be appropriately shallow cultivated. According to the weather forecast, the snow pea seedlings should be covered before the cold snap arrives. A layer of mulch. In northern areas where winter temperatures drop to minus 12°C, corn stalks can also be used to build east-west wind barriers.

Before and after the beginning of spring, when the temperature rises, you should hoe and loosen the soil in time to increase the ground temperature, pour a small amount of water according to the moisture content, and topdress with seedling fertilizer (usually 10 kg of urea) to promote early flowering of the plants. Pods. Small sheds can be built where conditions permit. Adding a small shed can make snow peas available on the market 15 days earlier, which is more efficient.

In early March, cotton stalks and branches can be used to support the field slightly to provide sufficient ventilation and light transmission. This measure can significantly increase the yield by about 20%.

During the initial flowering stage and full flowering stage of snow peas, 10 kg and 15 kg of urea should be applied respectively, and watering should be done frequently with small amounts of water. 4. Snow pea harvest and pest and disease control

It usually takes 7 to 10 days for snow peas to bloom and form into pods. The first batch of beans should be picked with scissors as much as possible to prevent the stems from being turned over and affecting the yield. If cabbage caterpillars and pod borers cause damage in the later stage, pyrethroid pesticides and phoxim can be used for control.
