2. The type of nutrients should be determined according to the weather conditions. In the rainy day, the light in the greenhouse is insufficient, and the photosynthesis is poor, which makes the sugar supply of tomatoes insufficient. At this time, the effect of spraying sugar on the leaves is better.
3. Spray the calcium fertilizer in time. The growth of tomato fruit requires more calcium. When the soil is insufficient for calcium, the fruit is prone to umbilical rot. Therefore, in the tomato fruiting period, calcium chloride, superphosphate, amino acid calcium, calcium supplement, etc. should be sprayed to meet the needs of tomatoes for calcium.
4. The interval between fertilization of tomato leaves should be appropriate. The suitable interval for fertilization of tomato leaves is 5-7 days. Spraying inorganic fertilizer on the foliage is easy to produce fertilizer, so the interval should be longer, generally not shorter than 7 days. The interval between spraying organic nutrient fertilizers may be suitably shorter, generally about 5 days.
5. Leaf fertilization of tomatoes should be combined with disease prevention. Foliar fertilization in winter and spring seasons often causes a significant increase in the humidity of the air in the protected area, which is likely to cause tomato diseases. Therefore, the number of times of spraying fertilizer on the leaf surface of the cloudy day is less. When applying fertilizer, it is necessary to add protective fungicides such as Antaisheng and DuPont Yibao, and to ventilate for a short time after fertilization to reduce the incidence rate.
6. Apply foliar fertilizer to the right amount. When the injured leaves occur, rinse off the excess fertilizer with water and increase the water content of the leaves to alleviate the damage of the leaves. When the soil water content is insufficient, watering is needed to increase the water content in the plant and reduce the concentration of fertilizer in the stems and leaves.
