香菇废菌糠作基肥对板栗土壤理化性质及产量的影响

Effect of Different Fertilization Treatment on Soil Physio-chemical Properties and Yield in Castanea mollissima Stand

设置香菇废菌糠、有机肥、复合肥3种施肥处理,研究不同处理对板栗（Castanea mollissima）林土壤理化性质及产量的影响。结果表明：在连续5 a施肥处理后,施用废菌糠和有机肥土壤有机质含量比施肥前增加30.12%和37.18%,其有机质含量比单纯施复合肥处理分别高出36.13%和34.87%;3个处理的速效N含量比施肥前增加27.78%~31.53%,施复合肥导致土壤p H下降16.08%,而施废菌糠或有机肥土壤p H分别上升5.60%和2.28%;3个处理的板栗产量相近,但是使用废菌糠具有良好的经济效益、生态效益和社会效益。

Experiments were conducted in 2010 on application with waste mushroom substrate, organic fertilizer and compound fertilizer in Castanea mollissima stand in Songyang, Zhejiang province. Five years＇ continuous treatment demonstrated that organic matter content in stand applied with waste mushroom substrate and organic fertilizer increased by 30.12% and 37.18% compared with that before the treatment, and 36.13% and 34.87% higher than that treated with compound fertilizer. The available N content in three treated stands increased by 27.78%-31.53% compared with that before. Soil pH value decreased by 16.08% in the stand treated by compound fertilizer, while increased by 5.60% and 2.28% in that treated with waste mushroom substrate and organic fertilizer. Yield of chestnut in three treated stand had no evident difference, but application of waste mushroom substrate had significant economic, social and ecological effect..
