橡胶树养分亏缺与死皮病及其对策分析

Relationship between Nutrient Deficiency and Tapping Panel Dryness of Natural Rubber Tree and Its Countermeasures

死皮病(TPD)是危害天然橡胶生产的最严重的病害之一,给生产带来了巨大的损失。研究者从不同的角度开展研究,提出了各种致病机理假说。本文作者着重分析了国内外胶园和橡胶树养分亏缺与死皮病发生的关系,提出了开展橡胶树养分循环的动态模拟研究,对于明了橡胶树养分生理需求规律及内部物质循环机制,指导生产上科学合理、按时按需施肥,维持胶园土壤地力、防止土壤酸化具有重要作用。

It is one of the most seriously diseases in natural rubber plant, the Tapping Panel Dryness （TPD） has caused the huge economic loss. The scientist have researched and probed on the TPD form different aspects, and proposed various pathogenic mechanism hypothesis. In this paper, the author analyzed the relationship between nutrient deficiency of rubber plantation and rubber trees and TPD. As a result, the dynamics simulation of nutrient cycling and applied research has an important significance to reveal the critical indicators of normal physiological nutrient demand, internal material recycling mechanism of rubber trees, guide the scientific and rational fertilizing, maintain soil fertility and prevent soil acidification in production.
