Yield-increase accelerant for preventing flower and fruit dropping of large cherry and preparation method thereof

Abstract

The invention discloses a yield-increase accelerant for preventing flower and fruit dropping of large cherry. The yield-increase accelerant is prepared from the following raw materials by the mass percentage: 0.2%-0.4% of phethalanilic acid, 0.1%-0.35% of 6-benzylaminopurine, 0.08%-0.2% of auxin, 2.8%-4.0% of brassinosteroid, 0.5%-2.5% of a penetrating agent, and the balance dimethylformamide. In addition, the invention also discloses a preparation method of the yield-increase accelerant. The yield-increase accelerant can promote pollination and fertilization of the large cherry, has flower and fruit retention effects, effectively prevents flower and fruit dropping of the large cherry, improves the fruit-setting ratio of the large cherry, induces cell division of large cherry fruits, improves the quality of the large cherry, increases the single fruit weight to the greatest extent, thereby improving the yield and achieving purposes of increasing yield, income and efficiency.

Description

technical field [0001] The invention belongs to the technical field of plant growth promoters, and in particular relates to a yield-increasing promoter for preventing flower and fruit drop of large cherries and a preparation method thereof. Background technique [0002] As a kind of early-maturing fresh fruit, the cultivation area of ​​big cherry has been continuously expanding in the country in recent years, but its fruit setting rate is low, flowers and fruits fall, and there is no output. In some years and some regions, it even has no production, which has restricted the development of this industry. the bottleneck. The main reason is that most varieties of cherries have a low self-fertilization rate or cannot self-fertilize, single variety, incompatible pollination among varieties, unreasonable configuration of pollination trees, which affects pollination and fertilization, and often occurs when the tree is full of flowers but no fruit, fruit set The phenomenon that the...

[0002] As a kind of early-maturing fresh fruit, the cultivation area of ​​big cherry has been continuously expanding in the country in recent years, but its fruit setting rate is low, flowers and fruits fall, and there is no output. In some years and some regions, it even has no production, which has restricted the development of this industry. the bottleneck

The main reason is that most varieties of cherries have a low self-fertilization rate or cannot self-fertilize, single variety, incompatible pollination among varieties, unreasonable configuration of pollination trees, which affects pollination and fertilization, and often occurs when the tree is full of flowers but no fruit, fruit set The phenomenon of low rate, when encountering low temperature and rainy weather during the flowering period, wild bees and insects are not active, and pollen is not easy to disperse

Due to poor pollination and fertilization, in order to increase the fruit setting rate of large cherries, some people spray a large amount of gibberellic acid during the flowering period, and gibberellin will induce parthenocarpy, forming a large number of seedless fruits, because the fruits have no kernels, and the young fruits are growing During the development process, it will shrink and fall off in a large amount. Even spraying borax and urea can not improve fruit setting, inhibit fruit drop, and have a great impact on yield
