Problems solved by technology

At present, my country's rubber tree planting area is about 17.5 million mu, with an annual output of about 800,000 tons of dry rubber, but the self-sufficiency rate of natural rubber is still less than 30%.
However, because there is usually a dry strip about 30cm long in the xylem of the hole, this shows that after the medicament is applied to the trunk, due to the excessive concentration of the local medicament, it will cause damage to the tree, which also shows that the dosage form of the existing rehabilitation medicament needs further improvement Improve

Abstract

The invention belongs to the technical field of rubber agriculture, in particular to a microcapsule of a rubber tree dead skin rehabilitation nutrient, and further discloses a preparation method and application thereof. The rubber tree dead skin rehabilitation nutrient microcapsule of the present invention uses the existing rubber tree dead skin rehabilitation nutrient as the core material, and the single-core structure formed by cross-linking of chitosan / sodium alginate / glutaraldehyde as the capsule wall material , to form microcapsules of rehabilitation nutrients with slow release effect, which can not only improve the symptoms of secant degumming, but also significantly increase the latex output.

Description

technical field [0001] The invention belongs to the technical field of rubber agriculture, in particular to a microcapsule of a rubber tree dead skin rehabilitation nutrient, and further discloses a preparation method and application thereof. Background technique [0002] Rubber tree (scientific name Hevea brasiliensis), belonging to the Euphorbiaceae Hevea genus, is a deciduous tree with milky sap. It is the main production carrier of natural rubber and has important economic value. The rubber tree is native to the Amazon forest, and its planting requires an average annual precipitation of 1150-2500 mm, but it is not suitable for planting in low-humidity places. China's rubber planting areas are mainly distributed in the whole of Hainan, southern and southwestern Yunnan and Leizhou Peninsula in Guangdong. At present, the planting area of ​​rubber trees in my country is about 17.5 million mu, and the annual output of dry rubber is about 800,000 tons, but the self-sufficienc...
