摘要 通过研究新型腐植酸氮肥对水稻产量和氮肥利用率的影响,以期为促进新型肥料的广泛应用提供理论依据。采用两地水稻田间肥效试验,共设4个处理:CK1(不施氮肥)、CK2(普通尿素N 180 kg/hm^(2))、HA1(脲基活化腐植酸氮肥N 180 kg/hm^(2))、HA2(常规掺混腐植酸氮肥N180 kg/hm^(2)),对比分析水稻成熟后籽粒产量和氮肥利用率的指标。结果表明:与普通尿素相比,梅川镇和大金镇水稻施用腐植酸氮肥均能显著提高籽粒产量和产值;梅川镇和大金镇水稻施用腐植酸氮肥的氮肥利用率分别提高15.0、6.7个百分点和10.9、4.2个百分点。综上,脲基活化腐植酸氮肥综合效果更好。 The effects of new humic acid nitrogen fertilizer on rice yield,and nitrogen use efficiency were studied to provide theoretical basis for promoting the application of new fertilizer.Four treatments were used in rice field fertilizer efficiency experiment in two places:CK1(no nitrogen fertilizer),CK2(ordinary urea N 180 kg/hm^(2)),HA1(urea activated humic acid nitrogen N 180 kg/hm^(2)),and HA2(conventional blended humic acid nitrogen N 180 kg/hm^(2))were used to compare and analyze the grain yield and nitrogen use efficiency after rice maturation.The results showed that compared with ordinary urea,humic acid nitrogen fertilizer could significantly increase grain yield and output value of rice in Meichuan and Dajin towns.The nitrogen use efficiency of humic acid nitrogen fertilizers in Meichuan and Dajin Town increased by 15.0 and 6.7 percentage points and 10.9 and 4.2 percentage points respectively.In conclusion,urea activated humic acid nitrogen fertilizer had better comprehensive effect.
