Beans are a kind of bean, which has beautiful appearance, good quality, rich nutrition and strong flavor. It is one of the vegetables that the majority of consumers love and it is also an indispensable vegetable variety in people's daily life. With the improvement of the living standards of urban and rural people, the supply of fresh vegetables in winter has been very urgent. The production of greenhouses is already one of the main means to solve the supply of beans in the autumn and winter of northern China. In this article, the bio-fertilizer expert, Jinbao, summarized the standardized planting points of the bean pods in winter greenhouses to the majority of farmers.
1. Greenhouse oil planting soil and fertilizer management
After the former rakes, the ploughs are ploughed in autumn and the depth is 20-25 cm. After the tumbling, the soil blocks are broken, and 4.5-7.5 kg of decomposed farmyard fertilizer is applied per square meter in the greenhouse. In addition, 45 g of superphosphate is added to the ash. One, as a base fertilizer. Sprinkle fertilizer on the ground, and then dig shallowly into soil for about 20 cm. It can be used to make oysters. The size of the pods is 1 meter wide. The length of the pods is the width that can be grown in the greenhouse. In order to ensure the complete decomposition of organic fertilizers, we recommend the use of commercially available organic fertilizers such as Dendrobium Fertilizer. Organic fertilizers have a wide range of sources, such as human and animal excreta, and household waste (such as rotten leaves, poultry, chicken bones, meat waste, etc.). Fermentation Fermentation Fertilizers are also cheaper to use: For example, the use of Fertilizer Fermentation Fertilizer Fermentation Fertilizers can be completed using 1 kg of Trichoderma Fertilizer for every 2 tonnes of waste. The fermentation process is simple and easy to operate, the fermentation time is short, and the fertilizer can be fermented after 7-10 days.

2. Greenhouse bean seeding
It can be soaked in warm water at 37°C for about 6 hours. Soaking time should not be too long. After soaking, the seeds are germinated in an environment of 25 to 28° C. After 2-4 days, the seeds can be sown when the seeds are slightly exposed. For 4-5 days before sowing, the sowing hoe shall be irrigated first. After irrigating the mulch, when the rammed soil is not sticky, it shall be turned one more time to level the rammed soil. When the pit is sown, the pods are planted in a single row. The row spacing is 3 seeds per hole and the seeding depth is 5 cm.
3. Greenhouse beans temperature and ventilation management
In the northern regions, the greenhouse temperature generally increases from late October to early November, and the temperature in the greenhouse gradually increases. Generally, it is not less than 20°C in sunny weather, not less than 15°C in cloudy weather, and 17-21°C in nighttime. In different stages of development of Snap Lens plants, the required temperature is also different. The temperature before scab needs to be maintained at 16-18 °C. After scab, it needs to be increased to 18-24°C to ensure production. In late October, the ventilation windows of the greenhouse can be fully opened around 10:00 am and closed until 4 pm. After mid-November, due to the turning of the outside weather, the individual vents in the greenhouse can only be ventilated at 10-11 am and the skylights should be closed at 2-3 pm. On a cloudy day, ventilation should be performed every day, but to narrow the vents or open a ventilation window one by one, do not open them all in order to avoid lowering the normal temperature in the greenhouse.
4. Prevention and treatment of diseases in greenhouse oil beans
Oil bean rust is one of the main diseases of the bean pods. Chlorothalonil and other wettable powders can be used 600 times, sprayed once every 10 days and sprayed 2-3 times. The aphids can be controlled with 70% insecticides, 2,500-fold solution, or 50% anti-influx 200 times. To prevent the combination of prevention and control.
5. Greenhouse beans harvesting
Greenhouse beans are harvested in autumn and winter in December. Harvesting should be carried out in batches in time to harvest the tender pods, usually harvested once every 3 days in the greenhouse, and the yield varies according to the characteristics of each pod. In short, the planting of pod beans must be controlled from every link, and at the same time, it must be managed in conjunction with the specific conditions of the local area.
