水稻机械化钵体摆栽氮肥施用量研究

Study on Nitrogen Fertilizer Application Levels of Rice with Mechanization

为使钵育摆栽技术与氮肥使用方法进行有机结合,以水稻品种龙粳30为试材,以新型水稻2ZB-633型摆栽机为试验对象,探究摆栽机最适宜的水稻本田氮肥施用量。结果表明:运用2ZB-633型摆栽机在23.1cm×10.0cm的最优摆栽密度下,全生育期总施氮量为127.5kg·hm-2时,水稻群体各重要性状最优,产量构成因素相互协调发展,可获得较高产量。

In order to make organic combined of the tray grown rice seeding transplanter technique and nitrogen fertilizer application method ,taking rice variety Longjing 30 as material ,taking new type 2ZB‐633 the tray grown rice seeding transplanter machine as test object ,after studying the plant density ,under different nitrogen fertilizer condition the high‐quality rice varieties in Heilongjiang province main grow th traits and yield compo‐nents were studied ,the most suitable application levels of nitrogen fertilizer for rice planting machine were ex‐plored .The results showed that by using 2ZB‐633 machine in the process of practical production ,total nitrogen content in the whole stages was 127 .5 kg·hm^‐2 under the 23 .1 cm ×10 .0 cm of the optimal planting density , the important traits of rice population ,production factors and yield could achieve the maximum .
