Wintering Cultivation Techniques of Chinese Bean New Year

The wintering cultivation of kidney bean is a way of planting in the sunshine greenhouse in the autumn or early winter, and is listed on the New Year's Day or Spring Festival. The overwintering management techniques mainly include: Cultivation facilities and the cultivation of the winter time, the growth period of Kidney Beans are all in the cold winter, therefore, the cultivation facilities used must have good insulation properties. Currently, only sunlight greenhouses with good performance can meet the above criteria. The sowing time should be determined according to the facility's heat preservation, lighting conditions, cultivation and management level, planting mouthwash and the required time to market. Variety selection medium ripe, early maturing varieties. Field management supplement seedlings: After the cotyledon of the bean is unfolded, it is necessary to check the seedlings in time. It is one of the key measures to improve the yield of bean seedlings. Watering: When enough seeds are planted at the end of the planting period, from the sowing seedlings to the first flowering seedlings to sit and live, it is necessary to carry out many times of cultivating the loose soil to promote the healthy growth of the roots and leaves, and prevent the seedlings from growing. In the event of drought, it can be watered once before pumping vines, and cultivating loose soil in time after watering. The first inflorescences of the kennel sit and begin to water, and later should ensure that there is a sufficient supply of water. Watering should pay attention to avoid flowering period, to prevent a large number of falling flowers, leading to production cuts. Before sealing the membrane outside temperature is high, should be watered in the morning and evening; buckle the outside temperature before the film is low, should be selected before noon, sunny watering, pouring After the water is ventilated, the moisture is discharged to prevent condensation at night and cause diseases. In winter, in order to prevent the ground water from being lowered by watering, watering should be minimized. Do not water the soil as long as the soil is moist. Generally, after the temperature rises in February, the number of watering can be gradually increased. Top dressing: After sitting in each flower bud, it is applied with 225-300 kg of ammonium sulfate or 50 kg of urea per hectare with watering, 15 kg of potassium dihydrogen phosphate or 15,000 kg of diluted human fecal urine. The future will be based on the growth of the plant when combined with pests and drugs. Foliar fertilizer can be used 0.2% urea, 0.3% potassium dihydrogen phosphate, 0.08 ammonium molybdate, photosynthetic fertilizer, high efficiency phytoremediation, etc.; can play a role in improving the rate of sitting, increasing production and improving quality. Control of leggy: seedlings 3 to 4 true leaf stage, foliar spray 15ppm paclobutrazol wettable powder solution, can effectively prevent or control plant leggy, increase the rate of single plant scab about 20%. If there is a phenomenon of leggy after the shed, spray the same concentration of paclobutrazol once again. Foliar application of 10 ~ 25ppm naphthaleneacetic acid and 0.08 boric acid solution during flowering can prevent flowering and falling down. Hanging vines: When the plants start to pull vines, they must use nylon ropes to hang the vines. When the plants grow to the top of the sheds, they can be dropped and vines to extend the harvest period, increase the yield, and remove the old leaves before falling. After being taken out of the shed, the vine part of the old leaf was removed and hung around the root along with the vine, so that the growth points of the plant throughout the shed were evenly distributed on an inclined plane that was low on the south and high on the north. Temperature management: Day and night ventilation after 7-10 days. With the decrease of the outside temperature, ventilation and ventilation time should be gradually reduced, but there should be a certain amount of ventilation at night to reduce the temperature and humidity of the shed. When the minimum temperature in the outside world drops to 13°C, the ventilation openings must be closed at night and only the top wind must be released. When the minimum temperature at night is lower than 10°C, close the tuyere and ventilate only during the day when the temperature is high. After entering the winter, the grass should be covered with grasshoppers at night to prevent freezing and extend the harvest period. The principle of post-membrane temperature management is: during the day after emergence, the temperature is controlled at 18-20°C, and ventilation should be promptly carried out at 25°C or above; nighttime control is at 13-15°C. During the open season, the temperature is maintained at 18-25°C during the day and 15°C at night. Temperatures higher than 28°C and below 13°C can cause dropouts. Pay special attention to avoid nighttime high temperatures. During the overwintering cultivation period, the price is highest before the New Year's Day and before the Spring Festival. Therefore, the harvest time should be concentrated on these two times. However, attention should also be paid to timely harvesting, avoiding harvesting too late, aging the soybean meal, and reducing product quality.
