通过对毛竹笋期切秆育苗与造林技术的7 a研究,结论是:(1)采用笋期切秆培育的毛竹苗具有竹秆分枝高度降低、竹节密度增加、枝条生长旺盛的特点,竹苗矮化、健壮,尤以笋期抽枝展叶前切秆培育的竹苗,其造林成活率为95.91%,第1年发笋株率为79.1%,发笋株单株发笋数为1.66个,分别比普通毛竹苗增加了21.31%、27.26%、53.7%,造林效果明显优于未切秆培育的普通毛竹苗.(2)切秆时期和切秆高度不同,对毛竹苗质量有明显影响.其中,笋期展叶前切秆、切秆高度在1.0~1.3 m的苗木造林效果最佳.(3)笋期切秆育苗是毛竹苗培育的一项技术创新,能大幅度提高造林成活率、发笋率,加快成林,提早受益,生态效益、社会效益、经济效益明显.
The results showed that: (1) Bamboo shoots with cut stalks had the characteristics of lower bamboo branch height, increased bamboo density and vigorous growth of shoots, Bamboo seedlings dwarfed, robust, especially shoots bamboo shoots cut before the development of stalks, the survival rate of afforestation was 95.91%, the first year the rate of bamboo shoots was 79.1%, bamboo shoots shoot number per plant 1.66, respectively, than ordinary bamboo increased 21.31%, 27.26%, 53.7%, afforestation effect was significantly better than the uncut stalk cultivated common hairy bamboo seedlings. (2) Cutting stalks and cutting height, the quality of bamboo shoots Which had the obvious effect, among which, the seedlings with cut stalks and cutting stalks height of 1.0-1.3 m had the best afforestation effect at the time of shoot development. (3) Cutting and nursery is the technological innovation of cultivating bamboo shoots, Improve the survival rate of afforestation, bamboo shoots rate, speed up the forest, early benefit, ecological benefits, social benefits, economic benefits.
