增施黑木耳废菌糠对毛竹笋生长及土壤的影响

Effect of Application of Waste Black Fungus Substrate to Shoot Growthand Soil of Phyllostachys heterocycla cv. pubescens Stand

摘要: 2014 年4 月，在浙江省丽水市莲都区的毛竹（Phylloctachys heterocycla cv. pubescens）林基地设置了4 个处理（对照不处理），分别施用60，75，90，105 m3?hm-2 黑木耳废菌糠，研究其不同施用量对竹笋生长和土壤性状的影响。结果表明，废菌糠不同施用量对毛竹鞭笋和春笋生长都有明显促进作用，增产效果显著。当废菌糠施用量达90 m3?hm-2 时，毛竹鞭笋的基径和长度达最大值，春笋的基径达最大值，单位产量也最高；随着废菌糠施用量的增加，毛竹林中土壤的有机质和水解性氮也随之增加，土壤容重随之降低，pH 值有所上升。

Abstract: Four treatments were implemented with one control to apply 60, 75, 90 and 105m3?ha-1 of waste black fungus substrate at Phylloctachysheterocycla cv. pubescens stand in Liandu, Lishui of Zhejiang province in April 2014 for studying effect on shoot growth and soil traits. The resultdemonstrated that each treatment could promote growth of rhizome and spring shoot with more yield. Ground diameter and height of rhizomeshoot, basal diameter of spring shoot and unit yield topped at stands with 90m3?ha-1. Quantity of waste black fungus substrate had positive relationwith organic matter content and hydrolyze nitrogen, but negative with soil bulk density. The experiment showed that pH increased a little.
