摘要
采用大田试验,选用12个生产中常用的早稻品种,进行施氮和不施氮2种处理,分析不同基因型水稻的产量、干物质积累和氮素吸收等情况,并以产量和氮素生理利用率(PE)为主要筛选指标,筛选出氮高效品种中嘉早17、中早35、金优463,并分析了氮高效早稻品种的籽粒性状。
Field experiments were carried out to study the effects of different nitrogen application rate on rice yield, dry matter accumulation and nitrogen uptake of different genotypes rice varieties, 12 early rice varieties were used as materials. Three high nitrogen use efficiency varieties, Zhongjiazao17, Zhongzao 35 and Jinyou463, were selected with yield and physiological nitrogen use efficiency (PE)as the main screening indexes.
