Problems solved by technology

Litchi fruit is prone to cracking in different degrees when it is close to maturity. In the early stage of fruit cracking, the pulp gradually lignifies, and in the later stage, the fruit begins to crack, exposing the pulp, and the pulp shrinks and turns black at the crack. When the humidity is high, germs take the opportunity to invade from the wound , causing the fruit to rot and become sour, losing its commodity value

Abstract

The invention relates to a method for preventing cracking of chicken beak litchis. The method comprises the steps of seed acclimation, seedling, grafting, land selection, water complementing, topdressing, trunk insect attack prevention and weeding. According to the method, seeds are acclimated and are submerged in a calcium solution of certain concentration for a plurality of times, the seeds are put in a refrigerating chamber to be subjected to cold resistance acclimation at the intervals of submersion, and the refrigeration time is prolonged gradually, and the temperature is reduced gradually. Besides, seedlings are subjected to drought resisting acclimation, and a calcium solution is sprayed on leaf surfaces. By the aid of the method, the fruit cracking rate is reduced, the litchi seedling survival rate and the litchi fruit yield are improved, and the commodity value is increased.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, and in particular relates to a method for preventing cracking of lychees. Background technique [0002] Litchi, evergreen tree, usually not more than 10 meters high, sometimes up to 15 meters or higher, gray-black bark; branchlets cylindrical, brownish-red, densely white lenticels, fruit oval to nearly spherical, 2-3.5 in length cm, usually dark red to bright red when mature, the seeds are all wrapped by fleshy arils, flowering in spring and fruiting in summer. There are many cultivated varieties of litchi, such as Jizui, Sanyuehong, Yuanzhi, Yuhebao, Heiye, Huaizhi, Hanging Green, Nuomi, Zhuangyuanhong, Chenzi, Orchid Bamboo, Dahongpao, Phoebe Leaf, Osmanthus, Crystal Ball, Concubine Xiao and so on. When the litchi fruit is close to maturity, it is very easy to crack the fruit in different degrees. In the early stage of fruit cracking, the pulp gradually lignifies, and in the la...
