为了解决观赏竹培育中的高度控制问题,以毛竹为例,分别对10 cm高的竹笋从基部开始和200 cm高的竹笋从130 cm处进行竹箨剥除,研究不同时间竹箨剥除对竹笋及幼竹高生长的影响。经3 a试验表明:2个时间节点均能不同程度地抑制毛竹高生长,其中10 cm高的竹笋从基部开始竹箨剥除的效果较好,与对照比较,竹笋日均高生长量下降了53.71%;新竹的节间长度缩短了25.3%;节的数量增加了37.5%;立竹枝下高降低了38.3%、全竹高降低了26.7%,均达到了极显著差异(P<0.01)。竹箨剥除对毛竹竹笋及幼竹高生长有明显的影响,可以缩短节间距离、控制植株高度,达到立竹矮化的目的。
In order to solve the problem of high control in the ornamental bamboo cultivation, taking bamboo as an example, the bamboo shoots with the height of 10 cm and the height of 200 cm were peeled from 130 cm at the base and 200 cm respectively. Effects of bamboo shoots and young bamboo height growth. After 3 years of experiment, the results showed that both of the two time nodes inhibited the growth of bamboo at different degrees. Among them, the height of 10 cm high bamboo shoot was stripped from the base, and the average daily growth of bamboo shoots decreased 53.71% respectively; the length of internodes of Hsinchu was shortened by 25.3%; the number of nodes increased by 37.5%; the height of bamboo stand was decreased by 38.3% and the height of bamboo was reduced by 26.7%, all of which reached the extremely significant difference (P <0.01). Bamboo stripping bamboo shoots and young bamboo high growth have a significant impact, you can shorten the internode distance, plant height control, to achieve the purpose of bamboo dwarf.
