摘要：

为了完善“甘薯/鲜食玉米”模式的配套栽培技术，寻求甘薯玉米套作体系下获取甘薯、玉米共同高产的最佳玉米播期和密度，通过大田试验，采用玉米播期与密度二因素裂区设计，研究不同玉米群体对玉/甘薯模式下甘薯农艺性状及产量的影响。结果表明：甘薯/鲜食玉米套作模式下以B1M1处理（6月5日播种，密度1.5万株/hm2）最高，总产值98609.19元/hm2，其次为B1M2处理（6月5日播种，密度1.8万株/hm2）和B3M2处理（6月25日播种，密度1.8万株/hm2），产值分别为87423.65元/hm2、82179.4元/hm2，分别比最低的B4M3处理（7月5日播种，密度1.8万株/hm2）高65.43%、46.66%、37.87%。薯玉套作体系中玉米在6月5—15日播种，密度为1.5万株/hm2的条件下有利于总产量和总产值的提高。

Abstract:

In order to perfect the sweet potato/fresh corn model of cultivation techniques of form a complete set, seek the best corn planting and density. Through the field experiments, the corn planting density and two factors crack zone were designed, researched different maize population of jade/sweet potato mode sweet potato agronomic characters and the influence of the production. The results showed that, the sweet potato/fresh corn mode B1M1 to deal with the highest, and the total output value of 98609.19 yuan/hm2, followed by B1M2, B3M2, the value of 87423.65 yuan/hm2, 82179.4 yuan/hm2 respectively, and the lowest B4M3 processing were high 65.43%, 46.66%, 37.87%. Jade relay itercropping system, corn chips on June 5th to 15th sowing seeds, the density of 15000 plants/hm2 condition conducive to the improvement of total output and output.
