Method for rejuvenating weak blueberry trees

Abstract

The invention discloses a method for rejuvenating weak blueberry trees, and belongs to the technical field of agriculture production increase. Mixed liquid medicines consisting of hymexazol and metalaxyl mancozeb are used for controlling harmful microorganisms in soil, so that sterilizing treatment can be thoroughly performed on the soil; then Qintu No. 1 is used for improving the physical state of the soil and increasing beneficial microorganisms in the soil; besides, through cooperation with sawdust, the gas permeability of the soil can be increased; through mutual cooperation of the mixed liquid medicines, the Qintu No. 1 and the sawdust, rooting of weak seedlings can be promoted, further the purpose of rejuvenating the weak seedlings is achieved, besides, the situation that subsequentmanagement is inconvenient when large trees and repair planting plantlets are planted in the same land block, which is possibly caused by local repair planting can be avoided, and existing yield at present can be reserved to the maximum extent; and besides, the measures can be taken for remedy when nursery stocks just begin to become yellow and growth vigor just begins to weaken, the mortality rate of the nursery stocks can be effectively reduced, repair planting can be performed without waiting for death of the nursery stocks or losses of culture value, and greater economic losses can be avoided.

Description

technical field [0001] The invention relates to the technical field of increasing agricultural production, in particular to a method for rejuvenating weak blueberry trees. Background technique [0002] Blueberry (Blueberry) is an emerging small berry fruit tree first developed in the United States in the early 20th century. Rich in anthocyanins, arbutin, flavonoids and other antioxidant substances, it has various health functions such as improving eyesight, enhancing memory, softening blood vessels, and anti-cancer. The Food and Agriculture Organization of the United Nations lists blueberries as "one of the five health foods for human beings". The development prospects at home and abroad are broad. [0003] In the early construction of the blueberry park, due to lack of experience, no attention was paid to soil improvement or soil improvement was not in place. Most growers only dig planting pits on the ridge surface after ridging, and only use about 0.01-0.02 square meters...

AI Technical Summary

Problems solved by technology

[0008] The present invention aims at the phenomenon that small seedlings cannot grow into high-yield trees for many years due to incomplete soil improvement and inadequate soil improvement in parks where blueberry planting was earlier, or the leaves of large trees turn yellow or even die in years with more rain, and provide a weak blueberry plant. The tree rejuvenation method realizes the rejuvenation of blueberry weak trees by combining soil sterilization, increasing soil aggregate structure, promoting soil beneficial microorganisms, and improving soil air permeability, so as to ensure high-quality and high-yield blueberry
