摘　　要：于2022年—2023年在贵州省贵定县沿山镇开展田间试验,设置4种处理,分析各处理对水稻生育进程、农艺性状、产量构成及经济效益的影响。结果表明:SRF+OM处理显著延长水稻生育期,提高有效穗数(397.5×10^(4)穗/hm^(2))和穗粒数(123.5粒/穗),实际产量达9125.8 kg/hm^(2),较CK增产108.5%,且产投比最高(21.5)。25%OM处理在减少化肥用量的同时,产量(8650.3 kg/hm^(2))较常规化肥(NPK)处理提高12.3%,土壤有机质提升8.7%。A field experiment was conducted in Yanshan Town from 2022 to 2023,and four treatments were set up to analyze the effects of each treatment on rice growth process,agronomic traits,yield composition and economic benefits.The results showed that SRF+OM treatment significantly prolonged the growth period of rice,increased the number of effective panicle(397.5×10^(4) panicle/hm^(2))and the number of grains per panicle(123.5 grains/ear),and the actual yield reached 9125.8 kg/hm^(2),which was 108.5%higher than that of CK,and the yield to investment ratio was the highest(21.5).With 25%OM treatment,the yield(8650.3 kg/hm^(2))was increased by 12.3%and soil organic matter was increased by 8.7%compared with conventional fertilizer(NPK)treatment.
