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.
