【摘要】 采用田间小区试验,研究了17年定位不同种类有机肥与无机肥配施对早稻产量和品质的影响。结果表明,长期有机-无机肥配施均可提高早稻产量,以绿肥与无机肥配施增产幅度最大,比单施无机肥高30.05%,比1倍稻草与无机肥配施高15.57%,比2倍稻草与无机肥配施高7.13%,比猪粪与无机肥配施高6.45%,产量差异达到极显著水平;有机-无机肥配施处理穗粒数、结实率、千粒重、穗数和蛋白质产量均较NPK处理高,以绿肥与无机肥配施表现最为明显,有机-无机肥配施可增加稻米出糙率和精米率,均以绿肥与无机肥最高,分别比单施无机肥高0.99%和2.06%,比CK高2.29%和2.62%,可减少稻米垩白度,以绿肥和无机肥配施垩白度最少,比单施无机肥少14.37%,比CK少32.88%。更多还原

【Abstract】 The effect of 17-year long-term mixed application of Organic-inorganic fertilizations on grain yield component and grain quality was studied in the field.The results showed that mixed application of Organic-inorganic Fertilizers can increase early rice yield especially Mixed Application of Green manure and inorganic fertilizer.It showed that in mixed using Green manure and inorganic fertilizer,output of early rice were 30.05% higher than that in only using inorganic fertilizer,15.57% higher than that in mixed using 1 times straw manure and inorganic fertilizer,7.13% higher than that in mixed using 2 times straw manure and inorganic fertilizer and 6.45% higher than that in mixed using pig manure and inorganic fertilizer.The difference among all the treatments was extremely significant.Mixed application of Organic-inorganic fertilizers,especially Green manure and inorganic fertilizer,had more effect not only on Panicle number,ripening rate,1000·grain weight,Grains per panicle but also protein yield,brown rice rate,milled rice rate compared to only inorganic fertilizer.It showed that in mixed using Green manure and inorganic fertilizer,brown rice rate and milled rice were respectively 0.99% and 2.06% higher than that in only using inorganic fertilizer and 2.29% and 2.62% higher than that in not using fertilizer.Mixed Application of Organic-inorganic Fertilizers could reduce Chalkiness,and mixed using Green manure and inorganic fertilizer could reduce by 14.37% and 32.88% compared to only inorganic fertilizer and not using fertilizer.更多还原
