菇渣对土壤理化性质和生菜生长的影响

Effect of Spent Mushroom Compost on Physiacal and Chemical Properties of Soil and the Growth of Lettuce

以发酵腐熟菇渣为原料,按不同体积配比施入土壤,进行生菜盆栽试验,探讨施用菇渣对土壤性质和生菜生长发育的影响。结果表明:施用菇渣后土壤的理化性状得到明显改善,土壤中的有机质,氮磷钾3元素的含量得到提高,以菇渣与土壤配比为1∶2时生菜叶面积最大,菇渣与土壤配比为1∶1时生菜产量最高。

With fermentative mushroom residue good as raw material,according to the different volume ratio were applied into soil,lettuce pot test,to investigate the effect of application of mushroom residue on growth and development of soil properties and lettuce.The results showed that after the application of mushroom residue,soil physical and chemical properties was improved obviously,soil organic matter,nitrogen phosphorus and potassium content of three elements was improved,when mushroom residue and soil ratio was 1∶2,area of the lettuce leaves was the largest,when mushroom residue and soil ratio was 1∶1,yield of lettuce was the highest.
