Method for improving fruit setting rate of tomatoes

Abstract

The invention relates to a method for improving the fruit setting rate of tomatoes. Pesticide preparations with p-chlorophenoxyacetic acid, brassinolide and oligosaccharins as active ingredients are mixed, prepared diluent is injected into a small portable sprayer by referring to the dosage of 20-40 mg / kg of the p-chlorophenoxyacetic acid in the composition and diluting the composition according to the same dilution ratio when 2 / 3 of flowers on inflorescences of the tomatoes are opening, the small portable sprayer is aimed at flowers to be processed which are subjected to uniform atomization and spraying to form tomato flower dripping, and the liquid is prevented from being splashed onto tender leaves to the greatest extent. The method can remarkably improve the fruit setting rate of tomatoes in summer and autumn, make the fruit setting rate basically reach the planting level in spring and improve the economic benefits of planting and meanwhile can reduce the gray mold incidence rate of the tomato fruits and facilitate yield and revenue increasing.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for improving the fruit setting rate of tomatoes. Background technique [0002] Tomatoes are temperature-loving but not heat-resistant crops. Under general cultivation conditions, the optimum temperature for photosynthesis is 20-25°C. If the temperature is 15°C lower or higher than 30°C, it will affect the normal flowering and pollination, and affect the fruit setting rate. In my country, the temperature in summer and autumn is relatively high. If there is no artificial pollination or other auxiliary pollination methods, the natural fruit setting rate of tomatoes is very low. Improve the fruit setting rate, but the effect of simply relying on "Tomato Spirit" or 2,4-D to treat flowers is still not ideal. Generally, the fruit setting rate is only 50% of that in spring, which cannot reach the expected value of planting and production, and the economic benefits are not...

In my country, the temperature in summer and autumn is relatively high. If there is no artificial pollination or other auxiliary pollination methods, the natural fruit setting rate of tomatoes is very low. Improve the fruit setting rate, but the effect of simply relying on "Tomato Spirit" or 2,4-D to treat flowers is still not ideal. Generally, the fruit setting rate is only 50% of that in spring, which cannot reach the expected value of planting and production, and the economic benefits are not ideal
