摘  要：
通过研究不同用量腐植酸有机肥与化肥配施对水稻增产效果的影响,筛选腐植酸有机肥的最佳施用方法和施用量。试验结果显示,施腐植酸有机肥对水稻增产增收效果显著。与不施肥处理(处理1)和纯施化肥处理(处理2)比较,罗山试验点分别增产28.2%~78.5%和15.5%~39.3%,固始试验点分别增产29.2%~75.2%和15.4%~35.6%。其中,以基施氮肥8千克/亩和腐植酸有机肥60千克/亩(处理8)效果最好,产值分别增加78.5%和75.2%;其次是氮肥8千克/亩和腐植酸有机肥20千克/亩基施处理(处理7)、氮肥8千克/亩和腐植酸有机肥30千克/亩基施和追施各半处理(处理5),且处理8、处理7和处理5三者间均无显著差异。从产量构成因子来看,腐植酸有机肥促进水稻增产主要是增加了有效穗数和每穗实粒数。综合考虑肥料投入成本和增加产值,以处理7最为经济。因此,农业生产上推荐氮肥8千克/亩和腐植酸有机肥20千克/亩基施。此外,在氮肥4千克/亩和腐植酸有机肥20千克/亩基施和追施各半施用(处理6)的情况下,水稻未减产,说明施用腐植酸有机肥可以适当降低氮肥用量。

摘  要：
The combined effects of different amount of humic acid organic fertilizer applied with chemical fertilizer on rice yield were studied. The optimum application methods and amount about humic acid organic fertilizer were screened. The results showed that the yield significantly improved with application of humic acid organic fertilizer. At Luoshan test site, the yield was increased by 28.2%~78.5% compared with no fertilization(treatment 1), and was higher by 15.5%~39.3% than chemical fertilizer(treatment 2); at Gushi test site, the yield was increased by 29.2%~75.2% compared with treatment 1, and was higher by 15.4%~35.6% than treatment 2. Among all treatments, the basal application of nitrogen fertilizer 8 kg/667 m~2 and humic acid organic fertilizer 60 kg/667 m~2(treatment 8) had the best yield-increasing effects, and the output was increased by 78.5% and 75.2% respectively at two test sites. Next were the basal application of nitrogen fertilizer 8 kg/667 m~2 and humic acid organic fertilizer 20 kg/667 m~2(treatment 7), the treatment of nitrogen fertilizer 8 kg/667 m~2 and humic acid organic fertilizer 30 kg/667 m~2 at the ratios of basal application and top dressing is 1:1(treatment 5). There were no significant difference among these three treatments. The results of yield components showed that rice yield increased induced by the application of humic acid organic fertilizer was due to the increase in numbers of panicles per plant and grains per panicle. However, consider the increase of input costs and output into account, the treatment 7 was the most economical, so it was recommended in the practice of agriculture. Moreover, the yield under treatment of nitrogen fertilizer 4 kg/667 m~2 and humic acid organic fertilizer 20 kg/667 m~2 evenly applied as basal and top dressing(treatment 6) had not declined. The result showed that the nitrogen fertilizer can reduce when applying humic acid organic fertilizer.
