毛竹笋用林冬笋覆盖试验初报

为提高毛竹笋用林冬笋产量 ,对试验竹林采取冬季覆盖加温技术 ,分别用稻草和竹叶 2种覆盖材料进行不同厚度覆盖处理。试验结果表明 ,它们均能提高冬笋产量 ,覆盖样地冬笋平均产量比对照提高 119.4 % ,覆盖栽培后对第 2年春笋和新竹产量影响不显著。对覆盖材料进行了正交分析 ,其中以稻草 2 0 cm加 2 0 cm厚的竹屑的处理效果最佳 ,产量提高了 186 .3%。覆盖后冬笋的投入产出比约为 1∶ 2 .5 7,经济效益可观。

Research on Bamboo Shoots of Winter in Bamboo and Bamboo-shoot Forest

To increase the output of bamboo shoots of winter in bamboo and bamboo shoot forests, we use covering (with straw and bamboo leaves) and raising temperature technology to the research bamboo forests. The results show that they will increase the output, such as in the research ground, it reaches to 119.4%, but the influence to the bamboo shoots of spring is not obvious. After the careful analysis, we get the best effects by using straws with 20 cm and scraps of bamboo with 20 cm, up to 186.3%. The economic effect is visible, since output is 2.57 times more than input.
