摘要
对黑腐酸生物有机肥在小麦生产上进行了田间施用效果研究。结果显示,处理C的小麦群体生长势和土壤环境优于处理B和A;在高肥力土壤上,处理C(底施化肥和黑腐酸生物有机肥)的平均产量为5 095 kg/hm^2,显著高于处理B(底施化肥加拔节期追施尿素)的平均产量4 705 kg/hm^2,极显著高于处理A(一次性底施化肥)的平均产量4 185 kg/hm^2,分别高出8.3%和21.7%;在中低肥力土壤上,处理C的平均产量为3 703.5 kg/hm^2,极显著高于处理B的平均产量3 349.5 kg/hm^2和处理A的平均产量2 934.0 kg/hm^2,分别高出10.6%,26.2%。说明在不增加化肥的情况下适当增施黑腐酸生物有机肥,小麦的产量得到显著提高。
The application effect of black humic acid bioorganic manure on wheat production was studied. The field test results showed that the wheat growth potential and soil environment of Treatment C were better than that of Treatment B and A, in high fertility soil, the average yield of Treatment C（base fertilizer plus black humic acid biological organic fertilizer）was 5 095 kg/hm^2, which was significantly higher than the average yield 4 705 kg/hm^2 of Treatment B（base fertilizer plus topdressing urea at the jointing stage of wheat）, and very significantly higher than the average yield 4 185 kg/hm^2 of Treatment A（one-time applied base fertilizer）, was higher 8.3% , 21.7% , respectively. And in the medium and low fertility soil, the average yield of Treatment C was 3 703.5 kg/hm^2, which was very significantly higher than the average yield of 3 349.5 kg/hm^2 of Ttreatment B and the average yield of 2 934.0 kg/hm^2 of Treatment A, was higher 10.6% , 26.2% , respectively. The experimental analysis showed that the yield of wheat was significantly improved by properly adding some black humic acid bioorganic fertilizer without increasing chemical fertilizer.
