How to apply foliar fertilizer to grow tomatoes?

How to apply foliar fertilizer to grow tomatoes? Please introduce the application method of tomato foliar fertilizer can refer to the following methods: 1. Determine the types of nutrients according to the growth of tomatoes. Generally speaking, the early results of plant growth is relatively exuberant, easy to grow, should use less to promote stem and leaf growth of foliar nutrients, can choose potassium dihydrogen phosphate, compound fertilizer and so on. Results during the peak period, the plant growth began to weaken, and foliar nutrients to promote stem and leaf growth should be used to promote seedling and leaf protection, such as urea, sugar and so on. two。 Determine the types of nutrients according to the weather. In cloudy and rainy days, the light in the greenhouse is insufficient and the photosynthesis is poor, so the sugar supply of two red persimmons is insufficient, so the effect of spraying sugar on the leaves is better. 3. Spraying calcium fertilizer on the leaf surface in time. Tomato fruit growth needs more calcium, when the soil calcium supply is insufficient, the fruit is prone to navel rot. Therefore, calcium chloride, calcium superphosphate and calcium supplementation should be sprayed in the fruiting period of two red tomatoes to meet the calcitonin needs of tomatoes. 4. The interval of foliar fertilization for tomatoes should be appropriate. The suitable interval of foliar fertilization for tomato is 5-7 days. Spraying inorganic fertilizer on the leaves is easy to produce fertilizer damage, so the interval should be longer, generally not less than 7 days. 5. Foliar fertilization of tomato should be combined with disease prevention. Foliar fertilization in winter and spring often leads to a significant increase in air humidity in the protected field, which is easy to cause tomato diseases. Therefore, the number of foliar fertilizer spraying in continuous cloudy days is less, and protective fungicides such as Antaisheng and DuPont Yibao should be added when applying fertilizer, and ventilation should be carried out for a short time after fertilization to reduce the incidence of disease. 6. Foliar fertilizer should be applied in an appropriate amount. When the leaves are injured, wash off the excess fertilizer with clean water and increase the water content of the leaves to alleviate the damage degree of the leaves. When the soil water content is insufficient, it should be watered to increase the water content in the plant and reduce the fertilizer concentration in the stem and leaf.
