Method for preventing fruit cracking of crisp plums and improving fruit quality

Abstract

The invention provides a method for preventing brittle plum fruit cracking and improving fruit quality, which comprises the following steps: S1, when base fertilizer is applied to soil in autumn, calcium fertilizer is additionally applied to the root of a brittle plum fruit tree, and the application amount of the calcium fertilizer is 1.2-1.5 kg / plant; s2, calcium fertilizer is sprayed to leaf surfaces once in the young fruit period and the expanding period of the crisp plums respectively, and the spraying amount of the calcium fertilizer is 1.5-1.8 kg / plant; s3, in the middle ten days of May, mulching film full covering is conducted on the crisp plum orchard, ditching is conducted between planting rows, and the ditching depth is 1-1.5 m; s4, one month before the fruits are ripe, a rain shelter is arranged above the crisp plum trees, and the crowns are completely sheltered from rain. By means of the method, the fruit cracking rate of the crisp plum fruits can be controlled to be 6% or below, meanwhile, the fruit quality is greatly improved, and the contradiction between the low requirement of the soluble solid content in fruit cracking prevention and high requirement of the soluble solid content in taste achieving is well solved.

Description

technical field [0001] The invention belongs to the technical field of prevention and control of plum fruit cracking, and in particular relates to a method for preventing crisp plum fruit cracking and improving fruit quality. Background technique [0002] Fruit cracking is a common physiological disease in the process of fruit tree cultivation. It is a physiological phenomenon that the fruit surface cracks in response to the uncoordinated internal growth and external environment. There are many factors that affect the fruit cracking of fruit trees. Different varieties of fruit trees are affected by the time of fruit cracking, the way of fruit cracking, and the characteristics of fruit cracking. . [0003] Prunus is a plant of the genus Prunus L. in the family Rosaceae. It is an important fruit tree species in temperate regions and is distributed in southwestern provinces of my country. However, the southern part of my country is rainy in summer, especially Chongqing City i...

Problems solved by technology

Liao Yuezhi et al. reviewed the causes of fruit cracking of fruit trees and the prevention and control techniques, mainly analyzed the causes of fruit cracking from the aspects of fruit tree genetics, physiology, external environment, and cultivation measures, and put forward corresponding control measures. However, different tree species and varieties, fruit There are differences in the period, method and characteristics of fruit cracking

Dong Bisheng and others summarized the main causes of fruit cracking in the mature stage of green crisp plum and the prevention and control measures, and pointed out that: the current research on fruit cracking of green crisp plum is still very little, especially the impact of endogenous plant growth regulators on fruit cracking is not enough. In addition, the causes of fruit cracking are more complicated. In the actual analysis process, various factors must be integrated, such as species, water, endogenous plant growth regulators, mineral elements, and daily management, to find out the most likely cause of fruit cracking. Reasons for prevention

[0005] The above-mentioned existing research shows that the prevention and control of plum fruit cracking still needs further research, and the existing methods still cannot solve the problem of efficient control of plum fruit cracking.
