山西南部麦后短季棉机械化播种技术初探

通过对小麦收获后麦茬的不同处理和不同的播种机械使用,探讨其对麦后直播夏棉的出苗及生长发育的影响。结果表明,用秸秆还田机切秆灭茬、旋耕机整地后,用玉米播种机播种光籽棉种或用非标准棉花毛籽播种机,采用先播后浇的栽培技术,简约、省时、省工,棉花出苗好,为棉花增加了1周的有效生长时间,为麦后直播棉稳产、高产、优质提供了一定的保证。

Preliminary Approach to Mechanization Planting Technology of Short Cotton after Wheat in Southern Shanxi

Different wheat stubble treatments and usage of machines were designed to study seedling emergence,growth and development of direct seeding short cotton.The cultivation technique to cut poles and break stubbles using field straw chopper,to prepare soil with rotary tiller,then to sow naked seed cotton with maize seeding machine or with non-standard fuzzy seed cotton seeding machine,sowing first and watering later was applied,the results showed the technology was rapid and labour-saving,good seedling emergence,one more week effective growth period for cotton,and guaranteed beneficial stable production,high yield and good quality of cotton sowing directly after wheat.
