土壤耕作与春季灌水次数对冬小麦产量要素与经济效益的影响

S274.1; 2016-2019年小麦季,在河北农业大学辛集实验站,以石麦15为供试品种,设4个处理:旋耕+春季2次灌水(RT2);深松+春季1次灌水(ST1);深松+春季2次灌水(ST2);旋耕+春季1次灌水(RT1),测定小麦开花与结实特性、灌浆和农田投入产出情况.结果表明:耕作与灌水次数对有效穗数无显著影响.1次和2次灌水条件下,深松处理均可显著降低不孕小穗数和不孕小穗比例,ST2和ST1处理穗粒数比RT2和RT1处理2个生长季分别高3.2％和5.7％.1水条件下,深松比旋耕处理有效灌浆期显著延长;2水条件下,降水较多的2018年表现为深松处理比旋耕处理提升灌浆速率;同次数灌水的深松条...

Abstract S274.1; 2016-2019年小麦季,在河北农业大学辛集实验站,以石麦15为供试品种,设4个处理:旋耕+春季2次灌水(RT2);深松+春季1次灌水(ST1);深松+春季2次灌水(ST2);旋耕+春季1次灌水(RT1),测定小麦开花与结实特性、灌浆和农田投入产出情况.结果表明:耕作与灌水次数对有效穗数无显著影响.1次和2次灌水条件下,深松处理均可显著降低不孕小穗数和不孕小穗比例,ST2和ST1处理穗粒数比RT2和RT1处理2个生长季分别高3.2％和5.7％.1水条件下,深松比旋耕处理有效灌浆期显著延长;2水条件下,降水较多的2018年表现为深松处理比旋耕处理提升灌浆速率;同次数灌水的深松条件下2个处理千粒重和旋耕处理相比,深松处理2个灌水次数的处理千粒重也均显著高于同样灌水次数旋耕条件下处理,2个生长季平均高4.8％.采用深松施肥旋耕一体化作业可有效降低农田耕作施肥投入,对提高收获指数和产投比也有积极意义,ST2比RT2分别提升4.8％和28.1个百分点,ST1比RT1分别提升和11.3％和46.0个百分点.
