【目的】对黄斑星天牛危害树木后留下的成虫产卵刻槽、羽化孔、幼虫的排粪孔和打孔注药后所造成的孔洞、伤疤、伤流进行修复,利用愈伤涂膜剂进行涂抹试验,并确定涂药量和涂药时间。促使伤口快速愈合,减少伤流和腐烂病发生。【方法】在树木冬眠初期或早春树木萌动前,将愈伤涂膜剂均匀地涂抹在树干伤口上,以涂满伤疤为宜。【结果】该药剂除了对50 a以上的树木伤口愈合率低外,对其它树木愈伤效果很明显,伤口愈合率可达58.6%,伤流株率下降了41.2%;腐烂病也可降低92.7%。【结论】愈伤涂膜剂在树干伤口上不但能够迅速形成具有透气性强的保护膜,起到封闭、阻隔作用,防止树液流失,而且还具有灭菌防腐,促进愈伤组织的再生能力。
【Objective】 The purpose of this study is to repair the ovum, scab and wound caused by the ovipositing cavities, feathering holes, Film smear test, and to determine the amount of coating and coating time. Promote rapid healing of wounds and reduce the occurrence of wounds and decay. 【Method】 Before the trees hibernated or early spring trees began to germinate, the callus coating agent was evenly applied to the wounds of the trunk to coat the scars. 【Result】 The results showed that in addition to the low wound healing rate of trees above 50 years, the healing effect was obvious to other trees. The wound healing rate reached 58.6%, the rate of wound strains decreased 41.2%, and the rot disease decreased 92.7%. %. 【Conclusion】 The wound-coating agent can not only quickly form a protective film with strong air permeability on the trunk wound, but also has the function of sealing and blocking to prevent the loss of tree fluid, and also has the advantages of sterilization and preservation and promotion of callus regeneration ability .
