1. Windproof production In early spring, greenhouse vegetables are mostly used for warming with greenhouse film to provide suitable temperature for vegetable growth. Therefore, it is very important to do a good job of windproof and protect the shed film and frame. Especially in the windy weather with high wind level, if the shed film is not fastened firmly, it will often be torn by the high wind, causing the whole shed to suffer. For this reason, pay attention to the weather forecast. Before the onset of strong winds, fix the scaffold, tighten the film line, check whether the film is damaged, find problems, and take targeted preventive measures as soon as possible.
2. Antifreeze The temperature in spring is the most unstable, which can easily cause frost damage. In March and April of each year, there will often be cold weather such as early spring. If the antifreeze measures are not in place, it may cause the vegetables to suffer freezing damage and even destroy the stubble. For this reason, it is necessary to pay close attention to the insulation of the shed before cooling down, such as controlling the amount of watering, sealing the shed film, and covering it with grass thatch or shed film to increase the temperature.
3. Disease prevention In early spring, the weather is volatile and the temperature fluctuates sharply, which often causes the occurrence and spread of vegetable diseases in the shed. Such as cucumber downy mildew, eggplant gray mold, spinach downy mildew, leek gray mold, tomato blight, etc. may occur at any time. For the above diseases, a combination of agricultural, physical, chemical and other prevention and control measures must be adopted. The temperature and humidity should be adjusted to the range suitable for the normal growth of vegetables. Fertilizer and water management should be strengthened, and plant regulators such as Bihu should be sprayed to enhance the freeze resistance and disease resistance of vegetable plants and minimize the occurrence of diseases.
