摘要
为有效解决橡胶树品种RRIM600死皮高发的问题,进一步验证死皮康复组合制剂的防效,采用死皮康复组合制剂对其死皮进行防治。试验在海胶集团广坝分公司和山荣分公司两地开展。结果显示,使用死皮康复组合制剂,死皮指数显著降低,降低值为55.89,平均防效达33.85%;恢复全线排胶植株的比例为37.68%。广坝分公司的数据显示,处理后全线恢复植株胶乳产量随季节变化有所波动,但产量相对稳定,经3年持续割胶后,仍然保持较高的胶乳产量,而自然恢复植株经1年持续割胶后,产量显著降低,死皮严重;山荣分公司的数据显示,处理植株胶乳产量明显高于自然恢复植株,相对于自然恢复,处理植株胶乳最高增产54.41%,平均增产也达22.34%。死皮康组合制剂能显著改善RRIM600死皮植株割线排胶症状,提高胶乳产量,且恢复后的植株耐割性较好,能持续3年或以上相对的稳产和高产。死皮康组合制剂及其配套施用技术防效相对较理想,是目前相对较理想的橡胶树死皮防控技术。
In order to effectively solve the problem of high incidence of TPD in RRIM600 and further verify the prevention and control effect of rubber trees TPD rehabilitation combination preparation,the TPD rehabilitation combination preparation was used to prevent and control the TPD.The test was conducted in Guangba Branch and Shanrong Branch of Hainan Rubber Group.The results showed that the index of TPD was significantly decreased by55.89;the average control effect was 33.85%;the proportion of plants recovering the whole line was 37.68%.According to the data of Guangba Branch,the latex yield of the recovered plants fluctuated with the seasonal changes,but the yield was relatively stable.After three years of continuous rubber tapping,the latex yield of the treated plants was still high,while the yield of the naturally recovered plants was significantly reduced after one year of continuous rubber tapping,and the TPD was serious.According to the data of Shanrong Branch,the latex yield of the treated plants was significantly higher than that of the naturally recovered plants.Compared with the natural recovery,the maximum latex yield of the treated plants increased by 54.41%and the average yield increased by 22.34%.The results showed that TPD rehabilitation combination preparation could significantly improve the tapping cutting symptoms of RRIM600 TPD plants,increased the latex yield,and the recovery plants had better tapping resistance,which could last for three years or more with relatively stable and high yield.The control effect of the TPD rehabilitation combination preparation and its matching application technology are relatively ideal,and it is a relatively ideal control technology of rubber tree TPD at present.
