摘要
试验对柞树施沼肥,使土壤有机质含量增加71.9%;在单叶重、单株产叶量等方面,增产效果突出,单叶重增加38.6%,单株产叶量增加47.5%,叶片鲜重增加38.6%,烘干后干重增加21.2%,说明叶质充实;熟蚕体重增加15.4%,公斤卵收茧量增加27.2%,养蚕成绩好。
The biogas fertilizer was used on oak tree planting in this test. The result showed that the soil organic matter increased by 71. 9%. The single leaf weight increased by 38. 6% and leaf yield per plant increased by 47. 5%,the yield-increasing effect was prominent. The leaf fresh weight increased by 38. 6% and dry weight increased 21. 2%,which showed good quality of leaves. The weight of matured tussah increased by 15. 4%,and the cocoon yield per kilo of tussah egg increased by 27. 2%.
