After entering the winter, the temperature is getting lower and lower, coupled with the increase of continuous rainy, snowy and hazy days and other low-light weather, the humidity in the shed is relatively high. In this case, what matters should be paid attention to in the management of the shed, I suggest that the vegetable farmers pay attention to the following five points. Temperature It is recommended that vegetable growers should not control the temperature too high during the time when the winter has just entered. According to the weather conditions, try to put grass curtains in the afternoon and pull the grass curtains early in the morning to maintain the temperature difference between day and night and provide as much light as possible for vegetables. Humidity In the current weather, the humidity in the shed is often relatively high. Therefore, it is necessary to ventilate as much as possible and ventilate as often as possible while maintaining the temperature in the shed, so as to reduce the humidity in the shed as much as possible. In addition, watering in winter should choose drip irrigation or micro-spraying as much as possible to avoid flooding with flooding. Small water should be poured in the shed without drip irrigation equipment, and the soil humidity in the shed should be controlled at 50% to 70%. Pruning In winter, there are more cloudy, rainy, snowy and hazy days. Therefore, when pruning and cutting branches and other agricultural operations, try to avoid this kind of weather, and choose to do it during the time period of high temperature around noon on a sunny day to facilitate wound healing. If the operation must be carried out on a hazy day such as a low-light day, wait for the humidity in the shed to drop before proceeding, and spray the medicine after the operation to prevent the occurrence of diseases. Organic nutritional supplement Organic nutrient supply. In the case of poor environmental conditions or poor plant growth, when the flower buds differentiate, the relative distribution of organic nutrients will be reduced, which will result in small flowers, short styles, etc., and the fruit will not grow well. Then, when the weather is fine, pay attention to flushing with water in sufficient quantities and a balanced ratio of large and medium elements to allow the plant roots to absorb, synthesize organic nutrients through photosynthesis, and then distribute them to the various organs of the plant. However, under special weather, the temperature is low, the light is weak, the photosynthesis of plants is slow, and the supply and absorption capacity of inorganic nutrients are limited. Therefore, at this time, attention should be paid to reasonable supplementation of organic nutrients, such as spraying glucose, amino acid and other foliar fertilizers. If the bad weather exceeds 5 days, compensation should be continued to ensure the organic nutrients needed for flower bud differentiation. Spray The current time node is a time period when a variety of diseases are prone to occur. Regular spraying is required to prevent the occurrence of *** disease early. Vegetable farmers can spray preventive agents such as chlorothalonil, thiophanate methyl, kasugamycin, etc. alternately according to the weather conditions before the continuous rainy and snowy days, and add crustaceans when spraying. Vegetarian and amino acid foliar fertilizer can improve plant resistance. Disclaimer: Some articles on this website are transferred from the Internet.
