摘要
与有机肥、牛粪和羊粪3种肥料作比较,设置施肥量4.50、7.50、11.25、12.00、15.00 t/hm2,以不施肥为对照,共21个处理,探讨新型微生物菌肥在冀北地区水稻种植的适用性及应用效果.结果表明,水稻产量表现为微生物菌肥＞有机肥＞羊粪＞牛粪,施用 11.25 t/hm2微生物菌肥的水稻结实率达98.68%,产量为7 740.15 kg/hm2,对水稻生长性状和产量构成有提升作用.综合分析,施用11.25 t/hm2 微生物菌肥为基底肥,能够促进水稻生长、增加产量,适宜在北方水稻高产栽培中推广应用.
Abstract
The applicability and application effect of new microbial fertilizer on rice planting in Northern Hebei were explored,compared with three kinds of fertilizers,namely organic fertilizer,cow manure and sheep manure.The fertilization amount was 4.50、7.50、11.25、12.00、15.00 t/hm2.With no fertilization as the control,a total of 21 treatments were used to study.The results showed that the rice yield was in the or-der of microbial fertilizer＞organic fertilizer＞sheep dung＞cow dung.The seed setting rate was 98.68%,the yield was 7 740.15 kg/hm2 with 11.25 t/hm2 microbial fertilizer.According to comprehensive analysis,11.25 t/hm2 microbial fertilizer as basal fertilizer could promote rice growth,increase yield,which was suitable for popularization and application in high-yield cultivation of rice in the northern.
