笋用毛竹林留养母竹时间的研究

本试验结果表明：集约经营的笋用毛竹林推迟留母可增产增值，谷雨前后留母比清明、谷雨间留母，竹笋产量增加26．9％，产值增加27．8％；比清明前留母产量与产值各增加40％。新留母竹胸围与座底母竹同粗，母 竹质量没有下降。

RESEARCH ON DEFERRED FARMING TIME FOR THE MOTHER BAMBOO OF SHOOT IN BAMBOO FOREST

Experimental results indicated that in the intensive farming bamboo forest, the bamboo yield and benefit could be increased if the mother bamboos reserve time had been deferred. Due to the deferred farming time of mother bamboo, in Guyu （6th solar term） but not in between Qingming （5th solar term） and Guyu, the bamboo shoot yield and benefit value could be increased 26.9% and 27.8%, respectively. By comparison, Guyu reserve time could exceed 40% benefit value than Qingming. The chest - girth of new cultivation mother bamboo was similar to base mother bamboo ; and retained the same quality.
