How to apply foliar fertilizer when growing tomatoes in greenhouse? The foliar fertilization of tomato in greenhouse generally starts from setting fruit to pulling seedlings, which plays an important role in the formation of tomato yield. First, according to the growth of tomato to determine the type of nutrition in the early stage, we can choose potassium dihydrogen phosphate, compound fertilizer and so on. Results in the peak period, urea, sugar and all kinds of special foliar nutrient solutions such as Dayuan No.1 and Jiakean can be selected. Second, the type of nutrition should be determined according to the weather conditions, the light in the greenhouse is insufficient, the photosynthesis is poor, the sugar supply of tomato is insufficient, and the effect of foliar sugar spraying is better. Third, foliar timely spraying calcium fertilizer in the tomato fruiting period, it is recommended to spray calcium chloride, calcium superphosphate, calcium amino acid, calcium supplement and other calcium fertilizer, in order to meet its needs for calcium. 4. The interval of foliar fertilization should be 5-7 days. Among them, the interval time of spraying inorganic fertilizer is generally not less than 7 days, and the interval time of organic fertilizer is about 5 days. Fifth, foliar fertilization should be combined with disease prevention to reduce the number of foliar spraying fertilizer in continuous overcast days, adding protective fungicides during fertilization, and ventilation for a short time after fertilization to reduce the incidence of disease. 6. when leaves are injured by improper use of foliar fertilizer, rinse the leaves with clean water, wash out the excess fertilizer, and increase the water content of the leaves to alleviate the damage degree of the leaves.
