Investigation of Tapping Cessation Trees Affected by Tapping Panel Dryness(TPD)and TPD Rehabilitation Research in Hevea brasiliensis
摘要
Abstract
To conduct a detailed investigation on tapping cessation trees affected by tapping panel dryness(TPD)at each tapping position in Teams 2 and 4 of the Danzhou experimental farms,Chinese Academy of Tropical Agricultural Sciences(CATAS),and carry out research on their rehabilitation,this study conducted tree-by-tree statistics of TPD-induced tapping cessation trees at 15 tapping positions in Team 2 and 13 tapping positions in Team 4 of the farm.Meanwhile,some tapping cessation trees were selected from each tapping position and treated with TPD rehabilitation slow-release granules developed in the early stage.The results showed that the TPD tapping cessation rates at each tapping position in Teams 2 and 4 ranged from 31.34%to 70.60%and 3.66%to 28.99%,respectively,with average tapping cessation rates of 46.15%and 14.14%.After the tapping cessation,trees were treated twice with the TPD rehabilitation slow-release granules,a survey conducted six months later showed that the TPD index at each tapping position decreased to varying degrees,with the average decreases in the TPD index in Teams 2 and 4 being 18.69 and 25.54,respectively.At the same time,the TPD length of the tapping line of TPD-affected trees was reduced to varying degrees,and the TPD length recovery rates ranged from 4.22%to 61.33%and 23.79%to 70.27%in Teams 2 and 4,respectively.The TPD tapping cessation rate at each tapping position in Team 2 was sig-nificantly higher than that in Team 4,and the treatment with TPD rehabilitation slow-release granules significantly reduced the TPD length of the tapping line and promoted the recovery of the tapping line of TPD-affected trees.This study will provide a reference for optimizing existing TPD rehabilitation technologies and realizing the simplification of TPD prevention and con-trol.关键词
