紧凑型玉米与大豆带状复合种植多模式的对比研究

Comparative Experiment on Multiple Patterns of Compact Corn and Soybean Strip Compound Planting

为了探明不同模式大豆玉米带状复合种植对大豆经济性状和玉米农艺与经济性状的影响,采用三种不同的种植模式对其占地面积和产量及农艺性状进行评价。结果表明,玉米∶大豆(2行∶2行)种植模式中每667 m^(2)大豆所占面积为366.67 m^(2),产量为54.78 kg,而玉米所占面积为300 m^(2),产量为536.23 kg。玉米∶大豆(2行∶3行)种植模式中每667 m^(2)大豆所占面积为405.80 m^(2),产量为71.28 kg,而玉米所占面积为260.87 m^(2),产量为466.29 kg。玉米∶大豆(3行∶4行)种植模式中每667 m^(2)大豆所占面积为435.90 m^(2),产量为86.02 kg,而玉米所占面积为230.77 m^(2),产量为411.56 kg。大豆和玉米产量与其所占面积成正比,但三种大豆玉米带状复合种植对大豆经济性状和玉米农艺及经济性状的影响差异均不显著。

In order to explore effects of different models of soybean corn belt compound planting on soybean economic traits,maize agronomic and economic traits,three different planting models were used to evaluate their area and yield.The results showed that the area of soybean was 366.67 m^(2) in planting pattern of corn:soybean(2∶2 row),with yield of 54.78 kg.,while the area of corn was 300 m 2,with yield of 536.23 kg.The area of soybean was 405.80 m^(2) in planting pattern of corn∶soybean(2∶3 row),with yield of 71.28 kg,while area of corn was 260.87 m^(2),with yield of 466.29 kg.The area of soybean was 435.90 m^(2) in planting pattern of corn∶soybean(3∶4 row),with yield of 86.02 kg.,while area of corn was 230.77 m^(2),with yield of 411.56 kg.The results showed that the yield of soybean and maize was proportional to acre area occupied.However,there was no significant difference in effects of three types of soybean corn strip composite planting on soybean economic traits and corn agronomic and economic traits.
