A method for improving the yield and quality of fruit of old orange pomelo trees

Abstract

The invention provides a method for improving the fruit yield and quality of an old orange pomelo tree, which belongs to the technical field of fruit tree management and comprises the following steps: 1) when spring buds germinate, the whole tree is retracted and pruned to three to four-level branches, Spraying fungicides for disinfection, cutting roots and fertilizing; 2) Before the length of spring shoots reaches 5cm, erase all spring shoots; 3) Apply compound fertilizer in early July, and cut summer shoots short in late July; 4) Step 3) After the summer shoots are shortened, 78-82% of the old trees in the whole garden germinate, and when 78-82% of the shoots germinate on each tree, put the shoots; 6) From late December to January, apply organic fertilizer and trace element fertilizer in the process of expanding holes and improving soil. The method overcomes the problems of scarce fruit-bearing and quality decline of citrus pomelo old trees more than 30 years old, and high yield can be realized in the next year, and the effect of increasing production and quality is remarkable, and has a positive effect on promoting the development of citrus pomelo 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...

[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
