本试验以旱作玉米为研究对象,通过免耕与传统耕作两种种植方式,主要从玉米长势、投入产出等角度进行了对比分析。结果表明,免耕玉米长势和产量与传统耕作相接近,但净产值与传统耕作的相当,而产投比和生态、社会等综合效益却远高于传统耕作,在沙区是一项很值得推广的耕作制度。 In this experiment, dry maize was taken as the research object. Through two kinds of no-tillage and traditional tillage planting methods, the contrastive analysis was made mainly from the perspective of maize growth and input-output. The results showed that the growth and yield of no-tillage maize were close to that of traditional farming, but the net output value was equivalent to that of traditional farming. However, the comprehensive benefits of production, investment, ecology and society were much higher than those of traditional farming. Farming system.
