耕种方式对小麦产量的影响

以矮抗58为试材，采取旋耕后直接播种（ CK）、旋耕＋耙实后播种、深耕（25 cm 左右）＋旋耕后播种、深耕（25 cm左右）＋耙实后播种4种耕种方式处理，研究了不同耕种方式对小麦生育进程、干物质积累动态、群体茎蘖数量动态以及小麦穗粒数、千粒重和产量的影响。结果表明：不同耕种方式对小麦生长发育进程、干物质积累动态、茎蘖数量变化动态以及穗粒数和千粒重均无显著影响，但对籽粒产量的影响达到了极显著水平。深耕（25 cm 左右）和耙实后播种均对小麦增产作用非常明显。采取深耕（25 cm左右）＋耙实后播种方式小麦产量最高，在生产上具有很好的推广应用价值。

Influence of Different Sowing Ways on Yield of Wheat

Taking wheat variety Aikang 58 as the test material, four sowing ways including seeding directly after rotary tillage （CK）, seeding after rotary tillage and solid harrowing, seeding after deep ploughing （about 25 cm） and rotary tillage, seeding after deep ploughing （ about 25 cm） and solid harrowing were adopted, the effects of different sowing ways on wheat growing process, accumulation dynamic of dry matter , number dynamic of tillers , kernel number per spike thousand kernel weight and yield of wheat were studied.The results showed that different sowing methods had no significant influence on the elements above , but the impacts on grain yield reached a very significant level.The effect of seeding after deep ploughing （ about 25 cm ） or solid harrowing were all very obvious.The method of seeding after deep ploughing （ about 25 cm） and solid harrowing leaded to the highest yield of wheat and was particularly important in production applications.
