What to Do About Flower and Fruit Drop in Greenhouse Tomatoes? A Full Breakdown of Preventive Measures

Greenhouse-grown tomatoes are mostly raised as seedlings in winter and bloom after the Spring Festival. If the environment deteriorates or management is improper, severe flower and fruit drop can easily occur. So how can flower and fruit drop in greenhouse tomatoes be reduced? Follow the editor to find out.

1. Scientific fertilization

When planting tomatoes, attention should be paid to base fertilizer and increasing the application of organic fertilizer to raise soil temperature. In the middle and late stages, attention should be paid to topdressing with quick-acting fertilizer. Generally, after the second truss has set fruit, watering should be accompanied by fertilization every other time. Especially in the middle and late stages, some foliar fertilizer should also be sprayed, applied together with photosynthetic nutrient film fertilizer. This can help the plant absorb large amounts of light fertilizer, light energy, and light, and is compatible with conventional fertilizers and nutrients to supply the plant's 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 swelling 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 capacity, increase yield and quality, and at the same time reduce flower and fruit drop, lowering the possibility of cracked fruit, stiff fruit, and deformed fruit.

3. Improve light conditions

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

4. Strengthen pest and disease control

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