Preparation for preventing citrus young fruits from physiological fruit drop and application method thereof

Abstract

The invention relates to a preparation for preventing citrus young fruits from physiological fruit drop and an application method thereof. The preparation is formed by 6-benzyl adenine, gibberellic acid, boric acid, zinc oxide, diluted hydrochloric acid, glycerol and alcohol. The preparation disclosed by the invention is prepared into 500-1000 times of diluted liquid; and young fruits are sprayed for the first time by the diluted liquid when 70-80% of blossoms fall and the young fruits are sprayed for the second time after 15-30 days. The preparation disclosed by the invention can effectively reduce the fall of the citrus young fruits and the effect is better than the effect of the single use of the 6-benzyl adenine (BA), the gibberellic acid (GA3) or a common BA+GA3 fruit keeping and anti-falling preparation; and the anti-falling effect is outstanding and the yield is increased to 115.8-304.3%. The product disclosed by the invention has no bad influences on the fruit and the single fruit is heavy; and the content of soluble solids in juice has no obvious difference from the fruit keeping and anti-falling preparation or clean water. A preparation method of the preparation is that the preparation is prepared at normal temperature and normal pressure, and is safe, energy-saving and environment-friendly; and the application method is simple and feasible, and is flexible to use. The preparation and the application method thereof are convenient to popularize and use.

Description

technical field [0001] The invention relates to a preparation for preventing physiological fruit drop of young citrus fruits, and also relates to a method for using the preparation for preventing physiological fruit drop of young citrus fruits. Background technique [0002] Citrus is one of the superior agricultural products planned by the state. In 2011, my country's citrus area was more than 33 million mu, with an output of more than 29 million tons, ranking first in the world in both area and output. However, citrus is sensitive to the environment during the flowering and young fruit stages. If it encounters abnormal weather such as rainy, drought or high temperature, most seedless and seedless citrus varieties (such as Wenzhou tangerine, navel orange, etc.) will experience severe physiological fruit drop in young fruit. Lead to a sharp drop in production or even a failure of harvest. For example, in 1983, in Lingchuan County, Guangxi, abnormally high temperatures occur...

Problems solved by technology

However, GA 3 The problems of short duration and easy crystallization of BA still exist. GA 3 and BA cannot give full play to their effects, and the fruit preservation effect is still not good
