When do peas ripen?

Pod-eating peas are long-day crops that like cold and are not heat-tolerant. Planting in winter, sowing in autumn and harvesting in autumn in the Yangtze River basin. Spring sowing and summer harvest are common in mountainous areas and northern China. When the pod is fully grown and the seeds are not yet grown, the peas in the pod are harvested.

Peas bloom and bear pods one after another, and the harvest should be carried out many times. Spring-sown peas began to be harvested in early April, and seedlings were pulled out in early June, with an yield of 400 kg per mu; Pea sown in autumn 65438+1early October-165438+1mid October was harvested, with an yield of 300 kg per mu.

breeding method

1, soil conditions

Pea has strong growth ability and low requirements for soil, and most soil can be planted. However, in order to obtain higher yield, it is best to plant in acidic soil with flat terrain, good drainage and rich humus, and avoid using alkaline soil for planting. It is best not to plant other leguminous crops within one year of planting land, so as not to affect the growth of peas. In order to ensure better soil permeability, it is necessary to dig deep and apply base fertilizer, and farmyard manure is the main fertilizer.

2. Choose seeds to accelerate germination.

Choose good seeds before sowing, and the quality of seeds is good. You should use full seeds without disease. You can't plant seeds directly after selecting them. This is because the seed skin is hard, so it should be soaked before planting to accelerate germination. Put the seeds in 40% salt water, stir gently, and remove the withered seeds floating on the water. After the seedlings are exposed, they can be planted in an environment of 0~2℃ for almost half a month.

3, timely sowing

If it is near the Yangtze River basin, it can be planted in autumn or after beginning of spring to avoid planting in the weather with frequent rainfall and high temperature. If it is in South China, it is recommended to plant it around beginning of autumn, and harvest it almost in winter or spring. Sow, the plant spacing can be about 10cm, the row spacing is 35cm, and 2-3 seeds are placed in each planting hole.

If the method of sowing is adopted, the seeds are evenly spread on the soil. When planting by drilling, sow after ditching, and finally cover with fine soil, and the soil depth should be just enough to cover the seeds.

4. Tian Tuan management

Pea root system is shallow, and its ability to absorb water and fertilizer is not strong. Weeds are easy to grow in planting areas. It is best to pull it out manually in time, without pesticides if possible. After the seedlings have just grown, they should be properly topdressing, which can be based on manure or compound fertilizer to avoid high-concentration fertilizer burning the roots of plants. Watering after watering can promote the fertilizer to be better absorbed by plants.
