[目的]为了提高单位面积的综合收益以实现农业的高效生产。[方法]2006年以玉米间作绞股蓝套作平菇的净收益为研究对象,开展玉米密度(30000~90000株/hm2)、绞股蓝密度(15000~75000株/hm2)以及玉米施肥量(纯N 75~255 kg/hm2)对净收益影响的试验研究。[结果]在这种种植模式中,玉米的种植密度对净收益有极显著的影响,绞股蓝密度有显著影响,而玉米纯N施肥量无显著影响。在玉米密度为75000株/hm2、绞股蓝种植密度为45000株/hm2、玉米纯N施肥量为210 kg/hm2时,净收益最高,达到33285元/hm2。[结论]玉米种植密度是影响净收益的主要因素,其次为绞股蓝种植密度,玉米施肥量则无显著影响。
[Objective] In order to improve the comprehensive income per unit area so as to realize the efficient agricultural production. [Method] In 2006, the net income of intercropped maize intercropping Mushroom was studied. The density of maize (30000 ~ 90000 plants / hm2), the density of Gynostemma pentaphyllum (15000 ~ 75000 plants / hm2) and the amount of maize fertilization ~ 255 kg / hm2) on the net income of the pilot study. [Result] In this planting pattern, the planting density of maize had a very significant effect on the net income, and the density of Gynostemma pentaphyllum had a significant effect, while the pure N fertilizer had no significant effect. The highest net income was 33285 yuan / hm2 when the density of corn was 75000 plants / hm2, the density of Gynostemma pentaphyllum was 45000 plants / hm2, and the corn N fertilization was 210 kg / hm2. [Conclusion] The planting density of maize was the main factor affecting the net income, followed by the planting density of Gynostemma pentaphyllum and the no significant effect of corn fertilizer.
