在大田试验条件下,研究了玉米‖大豆间作对辽西地区作物生长和产量的影响。结果表明:间作对玉米、大豆各项生长指标均有不同程度的影响;间作模式玉米的产量及产量性状指标均高于单作模式,尤其边行1的优势更为明显;灌溉条件与雨养条件下对比发现,间作模式下玉米产量性状指标差异不显著,而单作模式下穗长、穗粒数和产量灌溉处理高于雨养处理,并达显著水平。间作种植的大豆产量较单作种植有所下降,灌溉处理的间作模式比单作模式减产15.49%,雨养处理间作模式比单产模式减产29.76%;间作模式在灌溉条件下水分利用效率高于单作模式;综合分析表明辽西地区玉米大豆间作4∶4模式是提高产量和增加效益的适宜模式。
Under field conditions, the effects of intercropping of corn with soybean on crop growth and yield in western Liaoning were studied. The results showed that intercropping had different effects on the growth indexes of maize and soybean. The yield and yield traits of intercropping maize were all higher than that of single intercropping pattern, especially the advantage of borderline 1; Under the condition comparison, it was found that there was no significant difference in the index of yield traits of maize under intercropping, while the spike length, grain number per spike and yield irrigation were higher than those of rain-fed treatment under single cropping pattern. The yield of intercropped soybean was lower than that of single cropping. The intercropping pattern of irrigation treatment was 15.49% less than that of single cropping pattern, and the rainfed intercropping pattern was 29.76% less than that of single cropping pattern. The water use efficiency of intercropping pattern under irrigation condition was higher than that of single cropping pattern As a model; comprehensive analysis shows that the intercropping 4: 4 mode of corn and soybean in western Liaoning is a suitable mode to increase yield and increase efficiency.
