不同地面覆盖物对黄甜竹林土壤化学性质及生产力的影响

     

摘要

[目的]为黄甜竹高效培育奠定技术基础.[方法]研究了不同地面覆盖物及覆盖厚度对黄甜竹林分土壤化学性20生产力的影响.[结果]与对照(未做人为覆盖的自然状态)相比,谷糠、稻草和厩肥等3种地面覆盖物处理均不同程度地增加了0~20 cm土壤有机质、全N、全P、水解N、速效P、速效K的含量,其中厩肥覆盖处理的培肥能力最高.谷糠、稻草和厩肥等3种地面覆盖物处理不同程度地增加了黄甜竹林的出笋量,延长了笋期,促进了黄甜竹的生长.[结论]3种覆盖方式对黄甜竹出笋量及生长的影响效果依次为厩肥>谷糠>稻草.就覆盖厚度差异而言,覆盖厚度6 cm对黄甜竹出笋量及生长的影响效果优于覆盖3 cm处理.%[Objective] To lay a technique foundation for high-efficient breeding of Acidosasa edulis.[Method] The effect of different mulches and different mulch thickness on soil chemical properties and productivity of Acidosasa edulis forest were studied.[Result] The results showed that:compared with control,the treatment of barnyard manure,rice bran and straw mulches promoted content of organic matter,total nitrogen,total phosphorus,hydrolyzed nitrogen,available phosphorus and available potassium,and treatment of barnyard manure had the best effect than that of the treatment of rice bran and straw; The treatment of barnyard manure,rice bran and straw mulches promoted shoots amount and growth of A.edulis.[Conclusion] The treatment of barnyard manure had the best effect than that of the treatment of rice bran and straw; As far as the mulch thickness were concerned,the mulch thickness of 6 cm had the better effect than that of the mulch thickness of 3 cm.
