雷竹林地覆盖对竹笋产量的影响

The Influence of Phyllostachys praecox Forest Cover on the Bamboo Shoot Production

采用5∶5的双层覆盖法(下层用新杂草为发热层,上层采用发热增温性能好的新鲜砻糠为覆盖物作为保温层),探讨雷竹林地不同覆盖厚度、覆盖时间对竹笋产量的影响,结果表明:雷竹林地不同覆盖厚度、覆盖时间处理间的出笋数、鲜笋产量差异极显著,林地覆盖处理比没有覆盖处理出笋时间早、出笋数多、鲜笋产量高。以12月中旬林地覆盖厚度25 cm效果最好,雷竹的笋产量达6.75 t·hm-2,产值10.80万元·hm-2·a-1。

This paper discussed the influence of Phyllostachys praecox woodland different cover thickness ,covering time on the yield of bamboo shoots with 5∶5 double covering method ,through the contrast analysis ,and the results showed that:Phyllostachys praecox woodland different cover thickness ,the number of the bamboo shoot and fresh bamboo shoot yield difference between covering time processing was significant ,the bamboo shoot out earlier ,and the number of bamboo shoot ,and fresh bamboo shoot yield with the for-est coverage processing was higher was better than those without the coverage processing .Covers treatment B ( cover thickness 25 cm in Mid 10 days,December) Phyllostachys praecox income was high,up to 108000 yuan· hm-2/year for the yield of 6.75 t· hm-2.
