【摘要】 在中等肥力条件下,不同土壤质地和追氮方式对强筋小麦产量和品质的影响是极显著的。土壤质地,中壤土明显优于沙壤土,中壤土更宜栽培强筋小麦;追氮方式,中壤土和沙壤土均以拔节期追N 30%+孕穗期追N 10%的效果最好。追肥可后移到孕穗期,但要采取2次追肥,孕穗期追肥数量一般为施氮肥总量的10%。1次追肥应选择返青期追施40%N。更多还原

【Abstract】 Field test in 2003～2005 showed that under middle soil fertility,the effects of different soil textures and different nitrogen topdressing methods on yield and quality of strong gluten wheat was extremely notable.Strong gluten wheat planted in medium loam was the better than in sandy loam.It was best that the nitrogen topdressing methods in jointing stage with 30%N and in booting stage with 10%N of total N-fertilizer.Topdressing nitrogen is easy to be lost in booting stage,sot the topdressing nitrogen must be double and the amount of topdressing nitrogen must be 10% and topdressing nitrogen must be 40%N in returning stage.更多还原
