Safety tangerine girdling fruit retention method

Abstract

The invention relates to a safety tangerine girdling fruit retention method. During two weeks from the beginning of an early flowering phase of tangerine to flower withering, when it does rain and no rain water exists on a tangerine tree, at the smooth position of a large branch or a trunk, a bark is girdled in a winding mode, a girdling opening is formed and wrapped tightly by a clean plastic film until a brand new complete bark layer is grown out again at the girdling opening after 70-80 days, and the film is removed. The method has no obvious effects on tangerine root growth and tree vigor and the like, can effectively reduce physiological fruit drop of fruitlets of a seedless tangerine variety and can prevent excessive fruitlets from dropping physiologically due to the fact that the growth vigor of the seedless tangerine variety is too prosperous, so that yield is improved by 29.4-199.2%. Soluble solid content in juice has no significant difference compared with that of tangerines on a tree which is not girdled. The method is simple, economical and practical and suitable for large-scale popularization.

Description

Technical field [0001] The invention relates to a safe citrus girdling and fruit preservation method, in particular to a safe citrus girdling and fruit preservation method aiming at the physiological drop of young fruit of seedless and seedless citrus varieties. Background technique [0002] Citrus is one of the advantageous agricultural products planned by the state. In 2011, my country's citrus area and output ranked first in the world, with an area of ​​34.32 million mu and an output of 29.44 million tons. However, citrus is sensitive to the environment during the flowering and young fruit period. If it encounters abnormal weather such as rainy, drought or high temperature, most seedless and seedless citrus varieties (such as Wenzhou mandarin, navel orange, etc.) will experience serious young fruit physiological drop , Resulting in a sharp decline in production or even no harvest. For example, in 1983, Lingchuan County, Guangxi, experienced abnormally high temperatures durin...

AI Technical Summary

Problems solved by technology

In order to achieve a good fruit preservation effect by girdling without affecting the tree vigor, it must be girdled from the flowering period of citrus (usually early and mid-April) to 1 to 2 weeks after flowering fade (usually early and mid-May). The girdling mouth is completely healed after the end of the fruit physiological fruit drop (usually in the first and middle days of July), but it is difficult to do it with the current girdling method.
