Effect of New Microbial Fertilizer on Rice Yield Composition
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.
