死皮康复组合制剂在橡胶树品种‘93-114’上的应用

Application of Tapping Panel Dryness(TPD)Rehabilitation Combination Preparation for Clone‘93-114’in Hevea Brasiliensis

为有效解决橡胶树品种‘93-114’死皮高发的问题,进一步验证死皮康复组合制剂的防治效果,采用死皮康复组合制剂对其死皮进行防治。设置药剂处理、空白对照2个处理,2次重复试验分别于2015—2016年、2016—2017年进行,观测处理前后死皮植株割线症状、死皮相关指标及其胶乳产量的动态变化。处理植株死皮长度恢复率均值为79.84%,比对照增加45.20%;死皮指数降低68.36,防效可达71.41%,2次重复试验防效均值为59.34%;死皮植株胶乳产量显著增加,2次重复试验处理植株单株单刀鲜胶乳产量分别达204 g和144 g,处理植株胶乳分别比对照增产1.68倍和6.2倍。死皮康复组合制剂及其配套施用技术显著改善了‘93-114’死皮植株的割线症状,防效显著,显著增加植株胶乳产量,是目前相对较理想的橡胶树死皮防控技术。

To effectively solve the problem of high incidence of Tapping Panel Dryness(TPD)in‘93-114’and further verify the prevention and control effect of rubber trees rehabilitation combination preparation,TPD was prevented and controlled by rubber trees TPD rehabilitation combination preparation.Field tests were carried out in 2015—2016 and 2016—2017 respectively.The tapping cut symptoms,the index of TPD and latex yield of TPD plants were observed before and after treatment.The mean recovery rate of TPD was 79.84%,which was 45.20%higher than that of the control.The reduction value of TPD length was 68.36,the control effect could reach 71.41%,and the average value of the two repeated tests was 59.34%.The latex yield of TPD plants increased significantly.The latex yield of the two repeated tests per plant per tapping was 204 g and 144 g respectively.Compared with the control,the latex yield of treated plants increased 1.68 times and 6.2 times.The TPD rehabilitation combination preparation and its matching application technology can significantly improve the tapping cutting symptoms of clone‘93-114’TPD plants,increase the yield of latex,and the prevention and control effect is significant.It is a relatively ideal rubber tree TPD control technology at present.
