【摘要】 将稻草和砻糠作为雷竹林地覆盖基础层,本着保温、透气、保湿、环保、经济、易得等原则,选择鸡粪、麦麸、菜饼等作为添加材料进行雷竹林地覆盖增温试验。首先对3种材料进行单一添加试验,并根据试验结果对添加材料复配了3个配方进行第二轮的试验,试验结果显示,各处理均能有效提高雷竹笋产量,而在基础覆盖层间加入鸡粪(750 t·亩-1)+麦麸(500 t·亩-1)+菜饼(750 t·亩-1)增产最多。更多还原

【Abstract】 According to the principles of thermal insulation,high permeability,moisture retention,environmental protection,economies and easy availability,poultry manure,wheat bran and rapeseed dregs were selected as additive materials to the soil thermal insulation materials such as rice straw and rice hull in the forest of Phyllostachys praecox f. prerenalis. The singlefactor experiment was conducted to test the effects of the three additive materials respectively.Then,additive material were remixed with three formula in the second-round experiment. The results showed that the yield of Phyllostachys praecox f. prerenalis shoots increased significantly under all treatments. The optimal additive formulation was poultry manure 750 t·mu- 1,wheat bran 500 t·mu- 1and rapeseed dreg 750 t·mu- 1.更多还原
