Kidney bean planting technology after greenhouse autumn

Kidney Bean is one of the vegetables that we often see. Today, Xiaobian will share with you the technology of cowpea cultivation after the autumn.

1. Prepare before the broadcast. Deeply ploughing the ground, combined with the preparation of the land, 3,000 kg of high-quality decomposed organic fertilizer, 5 kg of urea, 30 kg of superphosphate, and 15 kg of potassium sulfate. After the soil preparation, fertilize the scorpion with a width of 110-120 cm.

2. Sowing. Soak seeds with 55 °C warm water and 0.1% potassium permanganate for 15 minutes before sowing. Wash them for 4 to 5 hours with water and dry them for sowing. In the sowing pot, the large row spacing is 70-80 cm, the small row spacing is 40-50 cm, and the ditch depth is 5 cm. In order to prevent exposure to sunlight, a ridge should be sealed on the seed, 2 to 3 cm high. Due to the high temperature and high humidity, the seeds germinate very quickly, and the soil can be emerged in about 3 days.

3. Field management. After the autumn in the greenhouse, the cowpeas should be planted in the morning, and the seedlings should be planted in the evening. If the seedlings are found and the ridges are broken, the seedlings should be replenished in time Generally, 5,500 to 6,000 plants are kept per mu. One small water was poured 10 days after sowing to promote seedling growth. Timely cultivating loose soil to promote root growth. When the tender pod grows to 3 to 5 cm, water is poured once every 7 to 10 days to keep the soil moist. From the beginning of the pod-forming period, the watering and fertilization are carried out in phases, generally fertilizing 2 times, the first time applying 20 kg of ammonium per acre, and the second applying 10 kg of urea per mu.

Cowpea tends to stop and grow in the high temperature season, commonly known as "Voice", should promptly prevent disease, treat insects, fight old leaves, cultivating weeding and top dressing, and promote plant growth, germination of side branches and flower buds, forming a peak of production. In addition, the spraying of 0.2% to 0.5% of boron, molybdenum solution and other micro-fertilizers in the growing season is conducive to pod formation.

4. Temperature management. From the beginning of September to the beginning of October, the sunshade net and the insect net are covered, and the nighttime temperature drops to 13 °C. After the shed, the wind should be strengthened during the day. The temperature in the shed should be kept at around 25 °C during the day, and the maximum temperature should not exceed 32 °C; the night temperature should be kept at around 20 °C, not lower than 13 °C. After the middle and late October, it enters the low temperature period. It is mainly used for cold protection and heat preservation. It is surrounded by greenhouses, especially in the north, to prevent the invasion of low temperature.
