Due to factors such as temperature, humidity, and improper management, greenhouse tomato is prone to phenomena of dead fruit, empty ear, and hollow fruit. To achieve the goal of high yield and high efficiency, in addition to cultivating strong seedlings, rational fertilization, and strengthening of temperature and humidity management, some skills are needed. The first is to remove the first flower of each flower, more flowers, early fruit thinning, and good fruit. The first flower should be removed in time. Each flower can spend 6 to 8 flowers. When the tomato grows to the size of the pigeon egg, remove the deformed, wounded, diseased, and oversized fruit. -5 is appropriate. The second is to master a little time and medication. If you spend too early, it is easy to form a stalemate. If it is too late, it is not easy to set fruit or produce cracked fruit, which will affect the commodity. The flower on each ear starts from the second flower (the first flower is removed), and each time it is basically 2-3 flowers open on the same day, and the flower is the best. It is best to spend time in the morning when the flower is just open. For point anther concentrations, the formulation concentration should be higher at low temperatures and slightly lower at high temperatures. Third, the fertilizer and water in the fruit expansion period should be sufficient to meet fruit enlargement and increase production and efficiency. When tomato walnuts are in size, they need to be in flourishing period. At this time, fertilizer and water must be sufficient, otherwise it is easy to appear stale fruits, small fruits, and empty fruits, which will affect the quality. Based on the application of adequate bio-organic fertilizer, the base fertilizer is applied to the quick-effect and long-acting full-nutrition balanced compound fertilizer. According to the number of long fruit spikes, determine the amount and type of fertilizing materials, focusing on the yield to yield. If there are a total of 6 spikes, they can be top-dressed 3 times in the first, third, and fifth fruit enlargement; if there are a total of 4 ear fruit, top-dressing in the 1st and 3rd fruit enlargement will be 2 times; when the fruit load is large, Appropriate increase in fertilizer 1 times. The top dressing is mainly composed of quick-acting compound fertilizer of potassium sulfate type, and the formula is preferably medium-nitrogen and low-phosphorus potassium, and the dosage is 20-30 kg per mu. In the later period of fertility, when the ground temperature is low, fertilizers containing humic acid or amino acids may be better used to buffer pure chemical fertilizers on the ground temperature and root system. At the same time pay attention to the middle in the 60 days after planting and then add a root water, it is recommended that per acre Chong Shi with humic acid or amino acids liquid fertilizer 10-15 kg. Apply high-nitrogen fertilizer on top of the dressing, avoid drastic changes in the soil, and spray the whole nutrient-type foliar fertilizer to avoid plant diseases. It is advisable to stop watering and fertilizing when the fruit of the penultimate ear begins to turn, in order to facilitate coloring and fruit enlargement. The fourth is to note that late leaf picking should not be excessive. In the period of fruit color conversion, many vegetable farmers promoted the conversion of fruit color, increased light, and removed all the leaves in the lower part of the ear. Some people also removed a lot of upper leaves, and too few leaves would seriously affect the photosynthetic accumulation and nutrition of the leaves. Insufficient, leading to hollow fruit. Therefore, snoring and picking leaves in the middle and late stages of growth are appropriate and should not be excessive.
