Detailed Explanation of the Latest Preventive Measures for Tomato Flower and Fruit Drop in Greenhouses

Tomatoes grown in greenhouses are mostly raised as seedlings in winter and bloom after the Spring Festival. If the environment deteriorates or management is improper, it can very easily cause a serious phenomenon of flower and fruit drop. So how can tomato flower and fruit drop in greenhouses be reduced? Come take a look with the editor.

1. Scientific fertilization

When planting tomatoes, attention should be paid to base fertilizer and more organic fertilizer should be applied to raise the ground temperature. In the middle and late stages, attention should be paid to topdressing with quick-acting fertilizer. Generally, after the second truss of fruit, watering should be alternated with fertilization once each time. Especially in the middle and late stages, some foliar fertilizer should also be sprayed, applied together with photosynthetic nutrient film fertilizer. In this way, it can help plants absorb large amounts of light fertilizer, light energy, light, compatible conventional fertilizers, and nutrients, supplying plant growth and development to the limit; one fertilization benefits the whole year.

2. Scientific regulation

Before tomato flowering, at the young fruit stage, and at the fruit enlargement stage, spray vegetable and fruit stem-strengthening agent once each time. This can activate the positive energy of the plant's ecological growth, broaden the pathways of the plant's conducting vessels, enhance the plant's water and fertilizer uptake, increase yield and quality, and at the same time also reduce flower and fruit drop and lower the possibility of cracked fruit, stiff fruit, and deformed fruit occurring.

3. Improve light conditions

Tomatoes are sun-loving crops, so when growing them in greenhouses, it is best to choose drip-free film for the greenhouse film, and new film should be used, so as to ensure the light transmittance of the greenhouse film and allow the plants to obtain more light. In winter, straw curtains should be uncovered and covered in a timely manner, and the dust on the greenhouse film should be thoroughly swept off. In seasons with low temperature and scant light, it is best to hang reflective film on the back wall to improve the light conditions of the greenhouse.

The main pests and diseases of greenhouse-grown tomatoes are late blight, gray mold, leaf mold, and viral disease. Before the disease occurs, spray 600 times diluted Xin Gao Zhi Mo. This can form a polymer protective film invisible to the naked eye. It can not only optimize the plant's water absorption, air permeability, and light transmission quality, but also block pest and disease damage and resist and defend against natural environmental disasters. When using pesticides for control, be sure to use high-efficiency, low-toxicity ones, so as to avoid pesticide residues harming human health.
