目前,三叶橡胶的无性繁殖多数使用芽接桩作力种植材料.芽接桩是在修剪部分主根和所有侧根之后移植的,移植裸根芽接桩的成活率是可变的,不适宜的天气条件会引起苗木的严重伤亡.还有个问题,即移植大田后抽芽不一致,有些芽休眠时间较长.当休眠发生率高达20%—30%时,就会观察到生长速度的差异.解决这些问题的一个办法,就是降低梢枯率或者提高成活率.最近在探讨的是如何使用植物生长物质诱导移植苗提早发根、提早抽芽、一致抽芽.这样有助于长时间抗御不良天气的影响.这里,我们还用生长物质诱导幼树提早分枝,通过提早茎围生长而缩短非生产期.
At present, the majority of clonal aneuploids reproduce by sprouting pile for force planting materials. Bud splicing is in the pruning of some of the main root and all lateral roots after transplantation, transplant nude root splicing survival rate is variable, inappropriate weather conditions will be Causing serious injury and death of seedlings.Another problem is the inconsistent sprouting buds after transplanting and some buds sleeping longer.When the dormancy incidence rate is as high as 20% -30%, the growth rate difference will be observed. One way is to reduce the shoot or improve the survival rate.Recently is to explore how the use of plant growth substances to induce early rooting of transplant seedlings, early buds, consistent buds.This will help to resist the impact of bad weather for a long time here, We also induced young branches to grow early with growing material, shortening the non-productive period by early stem-growth.
