1. Adjust suitable environmental conditions for lighting, temperature and humidity Let the crop grow in the most suitable conditions for most of the time, avoid the formation of wet and cold combined growth environment, paying particular attention to changes in the ground temperature. For tomato and other thermophilic crops, the temperature of 10 centimeters is suitable to be around 20 degrees Celsius, and the minimum ground temperature in the early morning should be kept above 13 degrees Celsius; the cold-resistant crops such as celery should be suitable at about 13 degrees Celsius, and the lowest is not lower than 10 degrees Celsius. 2, do a good job of plant and fruit management Pruning in time to remove the old leaves, yellow leaves and diseased leaves in the lower part of the plant, for the tomato crops that can not grow over the winter and the tip of the early shoots to promote fruit growth. Do a good job of pollination, remove excess and deformed fruit, make the plant as many fruitful as possible and produce good fruit; harvest mature fruits in time. 3, scientific watering, top dressing The watering method of drip irrigation or under-membrane irrigation is beneficial to save water and reduce indoor air humidity. Special attention should be paid to avoid watering on cloudy days and snowy days. There should be a reservoir or a storage tank in the greenhouse to increase the temperature of the irrigation water. When watering, the amount of water should not be too large. It is advisable to use small water for pouring. According to the characteristics of the crop's fertilizer requirements and plant growth, topdressing can be done to achieve balanced fertilization of nitrogen, phosphorus, potassium and trace elements, with special emphasis on the application of potash fertilizer, and to enhance the ability of plants to resist cold. Appropriate selection of liquid fertilizers that are easy to absorb should be effective. Generally, topdressing fertilizer should be applied once every 10-15 days. The drip irrigation method should be applied with 5-8 kg of water-soluble fertilizer each time.
