The latest preventive measures for falling flowers and fruits of tomato in greenhouse

Most of the tomatoes cultivated in greenhouse are raised in winter and blossom after the Spring Festival. if the environment becomes worse or improper management, it is easy to cause serious flower and fruit drop. So how can we reduce the falling flowers and fruits of greenhouse tomatoes? Come and have a look with the editor.

1. Scientific fertilization

Tomato planting should pay attention to the base fertilizer and increase the application of organic fertilizer in order to improve the soil temperature, and attention should be paid to the application of quick-acting fertilizer in the middle and later stage. generally, after the second moss fruit, watering should be applied every other time, especially in the middle and later stage, some foliar fertilizer should be sprayed together with photosynthetic nutrient film fertilizer. This can help plants absorb a large amount of light fertilizer, light energy, light, compatible conventional fertilizers, nutrients for plant growth and development to the limit, one-time fertilization benefits throughout the year.

2. Scientific regulation

Spraying vegetable and fruit Zhuangtieling once before flowering, young fruit stage and fruit expansion stage of tomato can activate the positive energy of plant ecological growth, broaden the path of plant transport catheter, improve plant water and fertilizer absorption, and improve yield and quality. at the same time, it can also reduce flower and fruit drop, reduce the possibility of fruit cracking, stiff fruit and abnormal fruit.

3. Improve the lighting conditions.

Tomato is a sunny crop, so when growing in greenhouse, it is best to choose drip-free film and use a new film, so as to ensure the light transmittance of the greenhouse film and make the plant get more light. In winter, it is necessary to uncover the grass curtain in time, and thoroughly clean the dust on the greenhouse film, and in the low temperature and low light season, it is best to hang the reflective film on the back wall to improve the lighting conditions of the greenhouse.

The main diseases and insect pests of tomato cultivated in greenhouse are late blight, Botrytis cinerea, leaf mold and virus disease. 600-fold liquid of new high lipid film can be sprayed before the disease occurs, which can form a layer of polymer protective film invisible to the naked eye. It can not only optimize the quality of water absorption, air permeability and light transmission of plants, but also prevent the invasion of diseases and insect pests, as well as resist and defend against natural environmental disasters. In the use of pesticides for prevention and control, must be used with high efficiency and low toxicity, so as not to produce drug residues harmful to human health.
