Abstract

Abstract: In order to guide the rational fertilization of rice (Oryza sativa L.) under the condition of mechanical side-deep fertilization, the effects of mechanical side-depth fertilization with reduced nitrogen application on rice growth, yield and economic benefit were studied with Fengliangyouxiang No.1 as material. A total of four different mechanical fertilization treatments were established: conventional broadcast fertilization (control), side-deep fertilization with no nitrogen reduction, side-deep fertilization with a 10% nitrogen reduction, and side-deep fertilization with a 20% nitrogen reduction. The results showed that,compared with control, the number of tillers, total root length, total root surface area, total root volume, number of root tips, number of rootbranches, 1 000 grain weight, eflective panicles, above-ground dry weight, total plant dry weight, and theoretical yield all significantly increased. The number of tillers was increased by 50.7%-59.0% and 17.8%-41.1% at the tillering stage and jointing stage, respectively, compared with the control. At tillering stage, the above-ground dry weight, root dry weight and total plant dry weight of side-deep fertilization were increased by 33.8%-57.4%, 18.2%-27.3% and 30.0%-52.5%, respectively, compared with control. The actual yield was increased by 1.7%-8.6% compared with control. Under the condition of side-depth fertilization, nitrogen partial productivity and total nutrient partial productivity increased gradually with the decrease of nitrogen application rate. The total root length, total root surface area, total root volume and rootbranches number of 20% nitrogen reduction treatment were significantly higher than that of side-deep fertilization with no nitrogen reduction, but the difference was not significant compared with 10% nitrogen reduction treatment. The benefit of side-depth fertilization with a 20% nitrogen reduction treatment was the highest, reaching 17 868.0 yuan/hm², which was 1 852.5 yuan/hm² higher than that of control.

Key words: rice (Oryza sativa L.), mechanical side-depth fertilization, reduced nitrogen application, growth, yield, economic benefit
