Method of increasing yield and improving quality of fruits of old tangelo trees

Abstract

The invention provides a method of increasing the yield and improving the quality of fruits of old tangelo trees and belongs to the technical field of fruit tree management. The method comprises the following steps that 1) when spring buds sprout, whole trees are treated by retractive pruning to three-four level of branching, a bactericide is sprayed for disinfection, and the fertilizer is appliedto cut roots; 2) before the lengths of spring shoots reach 5cm, all the spring shoots are erased; 3) a compound fertilizer is applied in early July, and the summer shoots are cut in late July; 4) after the summer shoots are short-cut, 78-82 percent of old trees are germinated in a whole garden, and the summer shoots are removed to let out spring when 78-82 percent of shoot tips on each tree sprout; 5) after the summer shoots are removed to let out spring, paclobutrazol and a foliar fertilizer are applied; and 6) an organic fertilizer and a trace element fertilizer are applied in the process of cave extension and soil improvement in the period from late December to January. By adopting the method, the problems of less fruiting and descending quality of the old tangelo trees over thirty years old are overcome, high yield can be achieved in the next year, the effects of increasing the yield and improving the quality are remarkable, and the method has a positive effect on promoting development of the tangelo industry.

Description

technical field [0001] The invention belongs to the technical field of fruit tree management, and in particular relates to a method for improving fruit yield and quality of old orange pomelo trees. Background technique [0002] Tangelo, which combines the hybrid advantages of orange and pomelo, has both the sweetness of orange and the fragrance of pomelo. It is juicy and crispy, with a unique flavor. It is rich in various vitamins and other nutrients needed by the human body. It is very popular among consumers. , the market price is optimistic, and it has the characteristics of high and stable yield, high quality and storage resistance, and the economic benefits of orange pomelo cultivation are remarkable. [0003] However, with the prolongation of the cultivation period, extensive management measures, lack of pertinence and systematization, the production problems of old orange pomelo trees are highlighted: the canopy is getting larger, field management is time-consuming an...

Problems solved by technology

[0003] However, with the prolongation of the cultivation period, extensive management measures, lack of pertinence and systematization, the production problems of old orange pomelo trees are highlighted: the canopy is getting larger, field management is time-consuming and labor-intensive, the tree body is sparsely bearing fruit, productivity is declining, and fruit quality is deteriorating. , especially the citrus pomelo trees that are more than 30 years old, the tree vigor is weakened, the yield is reduced, and the fruit is small and poor in quality, which is worrying.

If the tree is planed and the garden is rebuilt, it will affect the income for many years
