摘要
根据2007-2008年对常规粳稻郑稻18密度和播期的试验资料,分析了郑稻18产量性状和稻米品质变化等特性,表明郑稻18在河南省南阳地区的适宜播期为4月20-25日,基本苗适宜密度4.00万/667m2。
According to the experimental datum of Zhengdao18 of density and sowing date to analyse yield and quality change characteristics from 2007 to 2008,the results showed that the region of suitable sowing period was April 20-25 days of Zhengdao18 in Nanyang,Henan,basic seedling suitable density was 40 000/667 m2.
