Foliar fertilization in greenhouses generally begins after fruit set and continues until the plants pull, which plays an important role in the formation of tomato yield. Foliar fertilization should adopt different management methods for different situations in a timely manner. Specific attention should be paid to the following points: To determine the type of nutrition based on the growth of tomatoes: In general, early results, plant growth is relatively strong, easy to grow, should use less to promote the growth of leaf and leaf nutrition. Potassium dihydrogen phosphate, compound fertilizer, etc. can be used. At the end of the result, the growth potential of the plants began to weaken, and the leaf nutrients that promote the growth of stems and leaves should be used to promote the protection of the leaves. Urea, sugar and special foliar nutrients such as Dayuan No. 1 and Jiakean can be used. 2. The type of nutrition should be determined according to the weather conditions: cloudy snow weather, lack of sunlight in the greenhouse, poor photosynthesis, insufficient supply of tomatoes, and better foliar spray. 3. The foliar spray of calcium fertilizer in time: the growth of tomato fruits requires more calcium, and when the soil supply of calcium is insufficient, the fruit is susceptible to umbilical rot. Therefore, in the tomato's result period, it is advisable to spray calcium chloride, calcium superphosphate, calcium amino acid, calcium supplement and other calcium fertilizers to meet the needs of tomatoes for calcium. 4. The interval between the application of fertilizers on the leaves of tomatoes should be suitable: the appropriate interval for fertilizing tomato leaves is 5-7 days. Wherein, the inorganic fertilisers that are easy to produce fertilizers on the foliar spray should have longer intervals, generally not less than 7 days, and the organic nutrient spraying time can be appropriately shorter, generally about 5 days. 5. The foliar application of tomatoes should be combined with prevention and treatment of diseases. In the winter and spring season, fertilization in greenhouses will often result in a significant increase in air humidity in the protected areas, which can easily cause the incidence of tomatoes. Therefore, the number of sprayed fertilization materials on cloudy days is less. When fertilizing, protective fungicides such as Antaisheng and Dupont are added, and short-term ventilation is used after fertilization to reduce the incidence. 6. Improper use of foliar fertilizer: When a leaf is damaged, wash the foliar with clean water, rinse off excess fertilizer, and increase the water content of the leaves to ease the degree of leaf damage. When the soil moisture content is insufficient, watering is also required to increase the water content of the plant body and reduce the concentration of fertilizer solution in the stems and leaves.
