Due to the low temperature in winter, many areas rely on greenhouses to grow crops. After entering the summer, strong sunlight sometimes burns vegetables, which requires the use of greenhouse cultivation techniques. The water and fertilizer management of the summer vegetables in the hot summer days needs to be cautious, and find a suitable balance point to ensure a bumper harvest of crops. At present, it is the planting period or growth period of the summer vegetables, and the summer temperature is high and the light is strong. The key point of vegetable management is to strengthen the management of water and fertilizer, because reasonable watering and fertilization is decisive for the quality and yield of the vegetables. effect. Therefore, in the hot season in summer, watering and fertilizing must be reasonable. First, watering: According to the weather and the growth of vegetables, the size of water matches. Under normal circumstances, watering of vegetables in summer should pay attention to the combination of large water and small water. Using such a method, not only can the water required for vegetable growth be satisfied, but also the effect of reducing the temperature of the greenhouse and the ground temperature. However, it should be noted that it is forbidden to water the water at a high temperature at noon. The watering time is generally selected before 10 am and after 4 pm. In addition, the amount of water to be poured should also be based on the type of vegetables, because different vegetables require different water characteristics, such as melons and vegetables, the water demand is relatively large, and the number of watering can be increased appropriately. In addition, some vegetables are wet but afraid of drought, such as pepper, like the soil with strong permeability. Therefore, after planting the seedlings, the measures of water control can be used to ensure the soil moisture and control the plant growth. Second, fertilization: Summer fertilization is generally applied according to the appropriate amount of vegetables. Watering is frequent in summer, and excessive fertilization should not be avoided to avoid vegetable growth. In addition, the summer season is high, and the summer vegetables are cultivated. Generally, ridge cultivation is not used, and most of them are cultivated by flat hoe. However, the cultivation of sorghum is characterized by poor gas permeability, which is not conducive to the growth of vegetable roots. In order to solve this problem, summer vegetable fertilization can apply biological bacterial fertilizer at the time of planting, make full use of biological bacterial fertilizer to repair soil and change soil, so as to improve the disease resistance and resistance of vegetables. In addition, according to the growth of vegetables, appropriate functional fertilizers of chitin, amino acids or humic acids can be sprayed to increase the growth of vegetables and ensure the quality and yield of vegetables.
