2. Fine soil preparation: pea root system is weak, and fertile and loose soil is beneficial to pea growth. Therefore, it is very beneficial to plow and harrow the land properly during soil preparation to arrange seedlings and strengthen seedlings and better promote root development.
3. Suitable planting time: peas are cold-resistant crops, which are suitable when the growth period is cool and humid. Under normal circumstances, 18-20℃ is suitable for seed germination, while the suitable temperature for stem and leaf growth is 15℃. When the temperature is higher than 25℃, it will lead to the slow growth of seedlings, thus reducing the root tip yield of peas. Therefore, autumn sowing should not be too early, and late autumn or early winter is the best, because at this time.
4. Reasonable close planting: Peas are mainly planted to produce pea tips. Direct seeding and reasonable close planting can be adopted, with row spacing of 30-40 cm and plant spacing of 20-25 cm. Sow 3-5 peas in each hole, and loosen and cover the soil after sowing.
5. Herbicide weeding: Pay attention to weeding during the growth of peas to prevent weeds from robbing peas of nutrients. First of all, weeds should be controlled with glufosinate three days before sowing to achieve the best effect before weeds are unearthed.
6. Pest control: During the growth of pea tips, pests and diseases should be controlled in time. General pests and diseases are mainly powdery mildew, brown spot and aphids. It must be controlled in the early stage and larval stage to avoid causing symptoms such as dwarfing of plants.
7. Field management: Don't water the peas before they germinate. In case of drought in the later period, water should be done in time to keep the soil moist, which can promote the growth of pea tips and improve the quality and yield. In case of continuous rainy days, attention should be paid to timely drainage. The accumulated water in the field leads to excessive humidity and various diseases.
