针对市场上麻纤产品需求的日益增加及多功能新用途产品的开发和麻类作物种植面积不断减少[1－2]之间的矛盾，在不与粮争地的前提下，最大限度地利用土地资源，增加麻作产量，最大程度满足社会需求。通过田间小区试验，设置了大麻作前茬，在不同的收割期收获后接茬种植红麻的种植模式进行研究，两年结果显示：大麻—红麻接茬种植比单独种植红麻干皮（纤维）平均增产44.2％（2013年）和48.5％（2014年），总产量平均增产69.5％和74.0％。而且6月20日左右接茬净收益和产投比最高。从麻纤（麻皮）产量、净收益和产投比等指标综合来看，大麻和红麻接茬产量增产显著，实际经济效益可观，是值得推广的种植模式。%To solve the contradiction between the increasing market demand for bast fiber products and the continuously decreasing bast fiber crop planting area,we have to maximize the use efficiency of land resources and enhance the output of bast-fiber crops to meet the needs of society at the greatest de-gree. In this paper,field plot test was designed as the hemp was planted in the previous season and then kenaf was planted after hemp harvesting. Two year results of 2013 and 2014 showed that the total yield of hemp dry skin (fiber)increased by 44.2%(2013)and 48.5%(2014)respectively and the total yield increased by 69.5% and 74.0% respectively with this hemp—kenaf planting pattern,compared with that of single planting kenaf. Moreover,both of the net income and output to input ratio increased than that of single planting,the maximum values were obtained on June 20. The indexes of bast fiber yield, net income and output to input ratio,etc. indicated that the planting pattern of hemp—kenaf could in-crease the yield of bast fiber and improve farmers’economic benefits,thus it is worthy of large area ap-plication.
