施肥对毛竹林灾后竹笋影响效应研究

Effects of Fertilizer Treatment for Bamboo Shoot Growth after Disaster

2008年1月中下旬我国南方遭受持续性大范围雨雪冰冻天气袭击,造成毛竹林受灾严重。该试验研究不同施肥处理对各受损程度毛竹林灾后出笋数、笋产量和竹笋地径等因子的影响。试验结果表明:年度间和施肥处理间出笋数、笋产量和竹笋地径等因子均达到了极显著性差异,以施肥处理4为最佳施肥技术措施,各项因子增幅最大。

Phyllostachys heterocycla cv.pubescens Mazel was affected seriously by persistent wide range weather of snow and freeze,in the middle of January 2008 in South China.The shoot-emergence number,shoot yield,and shoot ground diameter in various disaster degrees were measured under different fertilizer treatments.The results showed that the shoot-emergence number,shoot yield,and shoot ground diameter were significantly different between fertilizer treatments,and the maximum increase amplitude occured in treatment No.4,which might be the best remedy technical measure for disaster recovery of Moso.
