摘要
在产生西瓜连作障碍土壤上增施有机肥,促进了连作西瓜生长,显著提高了西瓜根系活性,西瓜总根长、根表面积增大,改善了连作西瓜土壤中微生物的数量和区系,细菌和放线菌数量增加显著。4种有机肥料相比,3号、4号肥料优于1号、2号肥料。
The experiments of applying organic fertilizers to soil that had produced an impediment to continuous cropping watermelon growth were carried out. The results showed that applying organic fertilizers ameliorated soil ecologic environment, increased the root activity and watermelon growth and improved soil microflora. The numbers of soil bacteria and actinomycetes significantly increased after applying organic fertilizers. Among the 4 tested organic fertilizers, the effects of No. 3 and No. 4 organic fertilizers were better.
