不同类型配方肥在单季稻上的施用效果

Study on the application effect of different types of formula fertilizers on single crop rice

为探究不同类型配方肥以及肥料运筹方式的应用效果,文章开展了不同类型配方肥在水稻生产上减氮施用的田间试验。结果表明,施用配方肥能够显著增加水稻的分蘖数,提高水稻成穗率,增加有效穗数和提高结实率,稳定每穗粒数和千粒重,从而提高水稻产量。缓释配方肥处理在减氮10%时,相比于常规施肥处理,经济效益最大增幅可达11.6%,实现最大增收3 696.0元·hm^(-2)。综合主要农艺性状、产量和经济效益的表现,施用配方肥能有效降低水稻的生产成本,增加经济效益,最终达到减肥节本增效的目的。

In order to explore the application effects of different types of formula fertilizers and fertilizer application methods,field experiments were conducted on nitrogen reduction application of different types of formula fertilizers in rice production.The results showed that the application of formula fertilizer significantly increased the number of tillers in rice,increased the panicle formation rate,increased the effective panicle number and seed setting rate,stabilized the number of grains per panicle and thousand grain weight,and thus increased rice yield.When nitrogen was reduced by 10%in the slow-release formula fertilizer treatment,compared with the conventional fertilization treatment,the maximum economic benefit increased could reach 11.6%,achieving a maximum increase of 3696.0 yuan·hm^(-2) in income.Taking into account the main agronomic traits,yield,and economic benefits,the application of formula fertilizers effectively reduced the production cost of rice,increased economic benefits,and ultimately achieved the goal of reducing fertilizer usage amount,cost saving,and efficiency enhancement.
