采用裂区试验设计对陇东旱塬冬小麦夏覆膜秋穴播、秋覆膜穴播、露地条播 3种不同种植方式及锄草效果进行研究的结果表明 ,不同种植方式中以夏覆膜秋穴播产量最高 ,平均折合产量达 1813.8kg/ hm2 ,其较秋覆膜穴播、露地条播分别增产 2 6 1.0 kg/ hm2和 72 8.7kg/ hm2 ,麦田杂草分别减少 5 .3株 / m2和 10 .3株 / m2 ,是一种最佳种植方式 ;同一种植方式下 ,进行人工锄草的产量和水分利用效率分别较不锄草的提高 182 .0 kg/ hm2和1.2 0 kg/ (m m· hm2 ) ,农田耗水量降低 16 .7m m。
The split plot experiment design was used to study the effects of three different planting methods and hoeing effects on the winter mulching film, autumn mulching film and open-field mulching in the winter in the east of the Gansu Province. The results showed that in different planting patterns, The highest yield was 1813.8kg / hm2, which increased by 26.6 kg / hm2 and 72.77 kg / hm2 respectively compared with the mulching and open field sowing in autumn and decreased by 5.3% / m2 and 10.3% Strain / m2, which is the best planting method. Under the same planting mode, the yield and water use efficiency of artificial weeding were increased by 182.0 kg / hm2 and 1.2 0 kg / (mm · hm2) , Farmland water consumption decreased by 16.7m m.
