摘要
对2013—2015年河北省邯郸市曲周县麦棉套作一年两熟与春棉一熟2种模式下的投入、产出与效益进行了比较研究。结果表明:麦棉两熟种植模式在物化投入、机械费用、灌溉费用、人工投入等方面均高于春棉一熟,但小麦与棉花的总产值与纯收益显著高于春棉一熟,2013年、2014年、2015年纯收益分别较春棉一熟增加26.0%,57.3%与57.0%,不同年份间小麦与棉花价格是影响纯收益的首要因素。麦棉套作一年两熟种植模式在植棉效益大幅下降的背景下具有广阔的发展前景。
The input, output and benefit for wheat-cotton intercropping system and single cotton system were analyzed during 2013-2015. The results showed that the input of material investment, agricultural machine-using expense, irrigation spend and labor cost for wheat-cotton intercropping system were higher than that of single cotton pattern, but the output value and benefits of wheat and cotton were higher significantly than that of single cotton. The benefit of wheat-cotton intercropping system was 26.0%, 57.3% and57.0% higher than that of single cotton pattern in 2013, 2014 and 2015 respectively, and the price of wheat and cotton was the most important factor affecting the benefits. The prospect of wheat-cotton intercropping system was anticipated under the condition that the benefit of cotton production was not good.
