Application Effect of Fertilizers Containing Different Organic Matter on Rice Production
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.
