New bean planting cultivation technology

Generally, it can be cultivated in four seasons, and spring planting and autumn planting are used for soil production. The spring and autumn cultivation techniques will be introduced below.

(I) Spring cultivation

1. Nursery seedlings are planted or live broadcasted in advance for market launch. Protected field seedlings can be transplanted or covered with mulch cakes. Bean seeds have strong germination ability, do not need soaking seeds to promote germination, and seedbeds should not be too wet. The temperature should be maintained at about 25 ° C after sowing. In order to facilitate the emergence of seeds quickly, not bad seeds. Due to the weak root regeneration ability of kidney beans, seedlings should be transplanted, that is, the true leaves should be transplanted before and after, with as much soil as possible when transplanting.

The fertilized plots have medium or below fertility and should be cooked with organic fertilizer. 1500-3000kg per acre, deep ploughing and fine raking, preparing the ground for hoeing, and opening the box ditch for drainage and ventilation to promote root growth. If the bottom is not enough, water the soil one week before planting, and dry the ground before making the soil. Planting density varies according to the variety, generally vines, 180 cm wide. The ditch is 40-50cm wide, 4 rows per hoe, and the distance between trusses is 15-18cm. The dwarf species requires a ridge width of 120 cm, planting in 4 rows, and a hole distance of 18-33 cm.

For live seeding, the seeding depth is 3-5cm, 3-4 seeds per hole, return to the soil after sowing, and lightly step on. When the condition is poor, press the soil down with your feet to make the seeds and soil fully contact, which will help the seeds absorb water and emerge.

Before seedling emergence, try to avoid watering to prevent rotten seeds caused by the drop in soil temperature and soil compaction. If insufficient seedlings affect seedling emergence, you can lightly pour water once and plow the soil in time to break the compaction and increase the ground temperature.

2. After the field management emerges, set seedlings, leaving 2-3 plants in each hole, and ploughing once to promote the root system. About 20 days after emergence, depending on the growth of the seedlings, watering and fertilizing once, or continue squatting. Watering and proper topdressing should be started before climbing the vines. The dwarf species began watering and fertilizing after flowering and pod formation. During the pod-setting period, the plant growth began to weaken, and the management of water and fertilizer should keep up to facilitate the expansion of the fruit pods and the extension of the tops of the bean vines. The harvest of dwarf seed begins 50-60 days after sowing, and the harvest period is 30 days. The yield is 1200-1500kg per mu. 65-8 after sowing lettuce beans. It is harvested every day, the harvest period is 45-50 days, and the yield per mu is 1500-2500kg.

(Two) autumn cultivation

1. Timely sowing South of the Yangtze River is usually sown from early August to early September. North of the Yangtze River is usually sown from late July to early August. The early temperature of autumn beans is high and the growth is rapid. For example, if the sowing is too late, the temperature is low in the later period, the growth field is difficult, and the flowers and pods are easy to fall.

2. Appropriate dense planting of fall bean has short growth period and small plants. Increasing density can increase yield. Sowing 5-6 seeds per hole, leaving 3-4 seedlings.

3. Strengthen the management of autumn vegetables. In the growing season, heavy rain is often encountered. Drainage and weeding should be timely. In order to prevent falling flowers and pods, chlorine, phosphorus, and potassium fertilizers were applied in the medium term to increase the flowering and pod formation rate.
