为了找出黄腐酸有机肥在冬小麦上的最佳用量和施肥方法,本试验研究了不同用量的黄腐酸有机肥对新乡和驻马店2个试验点冬小麦产量和成产因素的影响。试验结果表明:施用黄腐酸有机肥对冬小麦增产效果显著。综合2个试验点结果,以处理3、处理4效果最好。如果考虑肥料成本,则以处理3的施肥配方和施肥措施最佳,即基施氮肥90千克/公顷,磷肥90千克/公顷,钾肥90千克/公顷,黄腐酸有机肥150千克/公顷;追施氮肥90千克/公顷,黄腐酸有机肥150千克/公顷。2个试验点影响产量差异的主要因素相同,都表现在亩穗数和穗粒数上,基本苗、最大分蘖变化不大。此外,处理5减产,但与处理1(CK)差异不显著,说明施用黄腐酸可以降低化学肥料用量。
In order to find out the best dosage of fulvic acid organic fertilizer on winter wheat and the fertilization method, this experiment studied the effect of different dosage of fulvic acid on the yield and yield of winter wheat in Xinxiang and Zhumadian. The results showed that the application of fulvic acid organic fertilizer on winter wheat yield significantly. Comprehensive test results of two points to deal with 3, the best treatment 4. If we consider the cost of fertilizers, the best fertilization formula and fertilization measures for treatment 3 are: 90 kg / ha nitrogen-based fertilizer, 90 kg / ha phosphate fertilizer, 90 kg / ha potassium fertilizer and 150 kg / ha organic fertilizer of fulvic acid Nitrogen fertilizer 90 kg / ha, fulvic acid organic fertilizer 150 kg / ha. The two main test factors affect the yield differences are the same, are reflected in the number of acres per spike and grains, the basic seedlings, the maximum tiller little change. In addition, treatment 5 reduced production, but with treatment 1 (CK) difference was not significant, indicating that the application of fulvic acid can reduce the amount of chemical fertilizer.
