毛竹林高产施肥技术探讨

Study on Fertilization Practice for High Yield Phyllostachys pubescens Grove

通过对福建省邵武市龙湖采育场毛竹林进行随机区组设计连续４ａ的施肥试验，主要结果经数理统计分析，获得毛竹林土壤养分（水解Ｎ、速效Ｐ、速效Ｋ）对毛竹林总产值（毛竹＋竹笋）的多元回归方程，作为毛竹林丰产施肥的基本理论依据；在保证高产高效的条件下，求得回归方程的最优解，作为高产毛竹林土壤养分的标准状态，其它毛竹林经测定其土壤养分后与之相比，便知土壤养分缺乏的种类和程度，由此确定合理施肥方案，则可成本低、效益好、产量高。

The test of fertilizer application in Ph.pubescens grove progressed between1989～ 1993 in Longhu Forest Farm of Shaowu,Fujian Province. According to the main re-sults and mathematical statistical analysis,the regression equation between soil nutrient(N、P、K)and output value of Ph.pubescens are important basis for fertilizer practice in Ph;pubescens grove. As a result,the standard of soil nutrient,with which the highest yield ofPh.pubescens would be produced,is set up.The amount of nutrient contents required in thesoil in other Ph.pubescens grove and the contrast should be determined.Then,how muchnutrient and what kind of nutrient are needed in the soil can be determined.
