摘要
于2007-2008年,选用小麦品种皖麦48,进行行距、密度、施氮总量、基追氮比例、追施时期等稻茬小麦5个关键农艺因素试验,研究其对产量性状的影响。结果表明:以行距15 cm、基本苗375万/hm2、施氮总量300kg/hm2、基施氮比例60%和追氮叶龄余数为2时,小麦产量最高,达到8852.4kg/hm2。
In 2007 - 2008, selected wheat varieties Wanmai 48, for spacing, density, total nitrogen, nitrogen - based ratio of nitrogen, such as rice stubble of wheat during the five key agronomic factors experiment was conducted to study its impact on yield traits. The results showed that： The line spacing 15era,seedlings 3750000 / hm^2, total N 300kg/hm^2, nitrogen - based and 60 percent the proportion of leaf nitrogen for more than 2：00, the highest wheat production reached 8852. 4kg/hm^2.
