摘要
为探讨沼气发酵有机肥在番茄基质育苗中的作用,以合大906番茄为试材,将不同比例的沼气发酵有机肥配入育苗基质,观测、比较各处理番茄生长情况。结果表明:在番茄育苗基质中,配入10%～30%的沼气发酵有机肥,对番茄幼苗生长均有一定的促进作用,其中以配入10%沼气发酵有机肥的配比最佳。40d内配入10%～20%沼气发酵有机肥的处理番茄幼苗多项生理指标均明显优于施用化肥的对照。在番茄育苗基质中配入适量沼气发酵有机肥可较好地替代育苗基质中化肥的使用,节约能源,并减轻环境污染负荷。
In order to better play the effect of biogas organic fertilizer on tomato seedling,Heda 906 was used as material,biogas organic fertilizer with different proportion in nursery substrate was used to observe and compare the tomato growth condition of different treatment.The result showed that adding 10%~30% biogas organic fertilizer to the nursery substrate would have certain promoting effect on the seedling growth,and the optimal proportion was 10%.Many physiological indexes of tomato seedlings of the treatments which adding 10%~20% biogas organic fertilizer were better than that of the control which were treated by chemical fertilizer within 40 days.Adding proper biogas organic fertilizer which might replace chemical fertilizer well in tomato nursery substrate could save energy and reduce environmental pollution.
