Pruning method for regulating and controlling guava production period

Abstract

The invention discloses a pruning method for regulating and controlling the guava production period. The pruning method comprises the following steps: pruning for four times: pruning a southern crown for the first time, and retaining a northern crown; when 3-5 pairs of leaves at the base parts of the newly grown branches of the southern crown subjected to the first pruning turn green, pruning the northern crown; after newly grown bearing branches of the southern crown subjected to the first pruning blossom and bear fruits, pruning the bearing branches of the southern crown and vegetative branches which do not bear fruits; after newly grown bearing branches of the northern crown subjected to the second pruning blossom and bear fruits, pruning the bearing branches of the northern crown and vegetative branches which do not bear fruits; and realizing that one fruiting tree blossoms and bears fruits for four times every year through the four times of pruning, and harvesting four batches of fruits. The pruning method can balance vegetative growth and reproductive growth of the guava fruiting trees, regulate and control the yield of fruits in different batches, stagger the ripening and marketing time of the guava fruits, increase the yield and improve the quality, thereby increasing the economic benefits.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, and in particular relates to a pruning method of fruit trees. Background technique [0002] Guava (Psidium guajaua L.) is also known as Guava, Jiyaguo, Bazai, etc. It belongs to the Myrtle family Guava plant. It is native to Mexico, Peru, Brazil and other places in tropical America. It is mainly distributed in Taiwan, Taiwan, and Brazil. Fujian, Guangdong, Guangxi, Hainan, Yunnan, Sichuan and other provinces (regions). Guava fruit is sweet and juicy, with an aromatic smell, rich in Vc, Va, folic acid, amino acids, calcium, iron and other nutrients and mineral elements, as well as pectin, tannin, alkaloids, triterpenoids, saponins, Carotene and other biologically active substances have anti-oxidation, antibacterial, anti-diarrhea, hypoglycemic, hypotensive, anti-mutagenic, anti-tumor and other effects. [0003] Guava has the habit of blooming and bearing fruit several times a year...

AI Technical Summary

Problems solved by technology

However, both production modes adopt one-time retraction and pruning of the whole tree crown after fruit picking in spring, which is easy to cause premature senility or excessive growth of plants due to excessive one-time pruning, which is not conducive to the sustainable development of guava production
