Pea four-season cultivation techniques:
1. Selection of land.
Pea seedlings root deeper, more drought-resistant, intolerant of moisture. It is appropriate to choose the last 3 to 4 years have not planted legume crops, high terrain, drainage and irrigation is convenient, fertile, loose, neutral to slightly alkaline soil planting.
2. Sowing at the right time.
Pea seedlings are cold and heat resistant, the optimal temperature for seed germination is 18 to 20 ℃. In addition to the summer, can be cultivated year-round, bamboo shoots. Southern regions in early spring February to March, September to October sowing, warm areas from the end of October to January can be sown.
3. Sowing, transplanting.
Each 667 square meters of land with 1500kg of rotted pig manure, 30kg of calcium superphosphate, 10kg of potassium chloride as a base fertilizer, and then plowing, for a width of 1.5m compartments. Then in the box surface holes, plant spacing 5 ~ 25cm, row spacing 40 ~ 50cm. using spot sowing, each hole sowing 5 ~ 6 seeds, each 667 square meters with 10 ~ 12kg of seed, when the seedling height of 8 ~ 10cm, 2 ~ 4 true leaves when transplanting.
4. Strengthen management
①Fertilizer. Fertilizer is mainly fast-acting nitrogen fertilizer, applied twice before harvest and once after each harvest.
②Watering. Pea seedlings avoid waterlogging, should pay attention to clearing the ditch drainage to prevent root rot. Long drought should be watered to keep the soil moist.
③ Plowing. Seedling shallow plowing, after the rain and fertilization, appropriate soil cultivation, pulling weeds, and pay attention to the introduction of vines, do not let them grow to the border ditch, so as not to step on the field work.
④Disease control. Pea seedlings common diseases are powdery mildew, yellow spot disease, yellow top disease, etc., can be 70% metribuzin 1200 times liquid, or 50% carbendazim 1000 times liquid, or 70% chlorothalonil 800 times liquid spray control.
5. Split harvesting.
30 ~ 50 days after sowing, seedling height 16 ~ 20cm when the beginning of the picking shoots, that is, picking the upper shoots with 1 ~ 2 pieces of young leaves have not yet unfolded, and then every 15 ~ 20 days to harvest 1 time, generally can be harvested 6 ~ 10 times.
