有机肥替代氮肥对水稻产量、品质及土壤肥力的影响
Effects of Organic Fertilizer Replacing Nitrogen Fertilizer on Rice Yield,Quality and Soil Fertility
摘要
Abstract
The rice variety Zhongzao 31 was used as the experimental material to conduct a 2-year field experiment.Nine different treatments were set up,including no fertilizer application(CK),single chemical fertilizer application(T1),optimized fertilizer application(T2),constant phosphorus and potassium content,with nitrogen fertilizer substitution ratios of 15%,30%,45%,and 60%,respectively(T3～T6),and increasing phosphorus and potassium content,nitrogen fertilizer substitution ratios of 15%and 30%,respectively(T7～T8).The results showed that in terms of rice yield,the combined treatment of organic fertilizer replacing nitrogen fertilizer(T3 and T8)significantly increased grain yield compared to single chemical fertilizer application(T1 and T2).Rice starch content increased first and then decreased with the increase of the proportion of organic fertilizer replacing chemical fertilizer,and T8 treatment was the highest.There were no significant differences in protein content,with the highest in T7 treatment and the lowest in T6.There were no significant differences in total phosphorus,total potassium,alkali nitrogen,and available potassium in the soil among all treatments.Therefore,the treatment of organic fertilizer replacing nitrogen fertilizer can increase rice yield,with the 30%nitrogen fertilizer substitution ratio showing better results,promoting absorption and utilization of nutrients.However,further experiments and research are needed to improve soil physical and chemical properties.关键词
