摘要
为探究不同有机质肥料在水稻生产上的应用效果,特开展水稻田间肥效试验.结果表明:增施有机和有机无机替换BB肥可有效提高水稻有效穗、结实率和产量;在同氮水平下,与常规施肥相比,商品有机肥区增产5.1%、减收7.5%,生物有机肥区增产10.9%、增收0.14%,有机无机复混肥区增产4.0%、减收0.03%;生物有机肥对于水稻的产量、经济效益和氮肥偏生产力、氮肥农学效率的效果都要优于商品有机肥、有机无机复混肥区.
Abstract
In order to explore the application effect of different organic fertilizers on rice production,field experiments on rice fertil-izer efficiency were carried out.The results showed that increased application of organic and organic inorganic replacement BB fertil-izer could effectively improve effective ear,seed setting rate and yield of rice.Under the same nitrogen level,compared with conven-tional fertilization,the yield of commercial organic fertilizer increased by 5.1%and decreased by 7.5%,that of bio-organic fertilizer increased by 10.9%and increased by 0.14%,and that of organic and inorganic compound fertilizer increased by 4.0%and decreased by 0.03%.The effects of bio-organic fertilizer on rice yield,economic benefit,nitrogen partial productivity and nitrogen agronomic efficiency were better than those of commercial organic fertilizer and organic and inorganic compound fertilizer.
