西辽河平原中低产田玉米-大豆条带种植适宜模式及效益分析OA
Suitable Pattern and Benefit Analysis of Maize-Soybean Strip Planting in Medium and Low Yield Fields in the Xiliaohe Plain
设置玉米-大豆行比2+2、2+4、4+4、6+4等4种复合种植模式,以单作玉米、单作大豆作为对照,对比分析不同种植模式对2种粮食作物的农艺性状、产量及综合经济效益的影响.结果表明,中低产土壤条件下,复合种植模式在群体产量和经济效益上远高于单作玉米种植模式,其中,2+4和4+4的复合种植模式综合经济效益较好,4+4复合种植模式综合经济效益最佳.因此,在研究区域内以行比为4+4的玉米-大豆种植模式具有较好的经济效益,适于在西辽河平原地区中低产田条件下推广.
The effects of different planting patterns on agronomic traits,yield and comprehensive economic benefits of two economic crops were compared and analyzed by setting four compound planting patterns of maize-soybean row ratio 2+2,2+4,4+4 and 6+4,with monoculture maize and monoculture soybean as control.The results showed that un-der the condition of medium and low yield soil,the population yield and economic benefit of compound planting mode were much higher than those of monoculture maize planting mode.Among them,the comprehensive economic benefits of 2+4 and 4+4 compound planting modes were better,and the comprehensive economic benefits of 4+4 compound planting mode were the best.Therefore,the maize-soybean row ratio of 4+4 model has good economic benefits in the study area,and is suitable for promotion under the conditions of medium and low yield fields in the Xiliaohe Plain.
