Anti-dropping and fruit-protecting agent used for planting fruits and preparation method of same

Abstract

The invention discloses an anti-dropping and fruit-protecting agent used for planting fruits, which includes, by weight, 4-6 parts of a rare earth micro-additive, 10-20 parts of a foliar surfactant, 7-9 parts of compound sodium nitrophenolate, 14-18 parts of diluted hydrochloric acid, 6-8 parts of gibberellic acid, 4-6 parts of boric acid, 3-5 parts of zinc nitrate, 7-9 parts of sodium tetraborate decahydrate, 10-14 parts of monopotassium phosphate, and 30-40 parts of water. The anti-dropping and fruit-protecting agent has good flower and fruit protecting effect, can greatly increase fruit setting rate of a fruit tree and effectively prevent flower and fruit dropping, and is toxic-free, harmless and pollution-free to fruits. The preparation method is low in raw material cost, employs simple and easy-to-obtained raw materials, has simple process, is easy to carry out and is easy to achieve in industrial production. The anti-dropping and fruit-protecting agent has excellent practical value and application prospect.

Description

technical field [0001] The invention relates to the technical field of fruit tree planting, in particular to a fruit fall prevention agent for fruit planting and a preparation method thereof. Background technique [0002] Generally, fruit trees are multi-flowered species, but due to the influence of tree body nutrition and environmental conditions, the phenomenon of flower and fruit drop in most fruit trees is very serious, and the natural fruit setting rate is generally about 1-7%. Pollination of fruit tree flowers and pollen germination, the most suitable meteorological conditions are temperature of 24°C to 26°C and relative air humidity of 70% to 80%; if the humidity is too low, the pollen will be stunted. [0003] There are many factors that cause physiological flower and fruit drop of fruit trees, such as poor development of flower organs, poor pollination and fertilization, abnormal climate, excessive tree growth, insufficient water and fertilizer, poor ventilation and...

Problems solved by technology

The known method of preventing flower and fruit drop in fruit flowering period is fruit-setting spirit. Although fruit-setting spirit can increase the fruit setting rate during the flowering period of fruit trees, it is difficult to prevent fruit drop during the fruit development period.
