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 specifically relates to a nutrient microcapsule for rehabilitation of tapping panel dryness, and a preparation method and application thereof, belonging to the technical field of rubberagriculture. The nutrient microcapsule for rehabilitation of tapping panel dryness in the invention adopts a conventional nutrient for rehabilitation of tapping panel dryness as a core material and amononuclear structure formed by cross-linking of chitosan / sodium alginate / glutaraldehyde as capsule wall material. The formed nutrient microcapsule has sustained release effect, can improve the symptoms of tapping for latex discharge, and significantly increases the yield of latex.

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 recovery nutrient agent, and further discloses its preparation method and application. Background technique [0002] Rubber tree (scientific name Hevea brasiliensis), belonging to Euphorbiaceae Hevea plant, is a deciduous tree with milky sap. It is the main production carrier of natural rubber and has important economic value. Rubber trees are native to the Amazon forest, and their planting requires an average annual rainfall of 1150-2500 mm. However, they are not suitable for planting in low-humidity areas. They are suitable for growth in acidic sandy loam with deep, fertile, moist, and well-drained soil. China's rubber planting areas are mainly distributed in the whole of Hainan, southern and southwestern Yunnan, and Leizhou Peninsula in Guangdong. At present, my country's rubber tree planting area is about 17.5 million mu, ...
