ABT生长剂在毛竹笋材两用林上的应用

Application of ABT growth regulator in dual purposePhyllostachys pubescens plantation

通过分析施用不同型号的ＡＢＴ生长剂对毛竹笋材两用林的发笋率、笋产量和新竹产量的不同影响，选择最佳ＡＢＴ剂型或组合。结果表明，质量浓度为４０ｍｇ·Ｌ－１的ＡＢＴ４号和ＡＢＴ５号混合使用对竹笋与竹材的产量提高为最佳，与对照组相比，发笋率提高了２８５％，笋产量提高了２９２％，新竹竹材产量提高了３００％。在笋材两用林中施用ＡＢＴ生长剂，竹笋与竹材的产量均有大幅度的增加。

It is a study on rate of shooting,shoot yield and newbambootimber yield of Phyllostachys pubescens plantation which are affected by using the ABT growth regulator.The results show that using of 40 mgL-1 of the mixture of ABT 4 and ABT 5 is better than singularly using each of them in improving shoot yield and newbambootimber yield.In this way,rate of shooting is increased by 292%,shoot yield increased 29%,newbambootimber yield increased 30%.In a word,shoot yield and bambootimber yield are increased sharply by using ABT growth regulator in the dual purpose Phyllostachys pubescens plantation.
