大豆玉米带状复合种植条件下的玉米品种筛选
Screening of Maize Varieties Under Soybean-Maize Strip Intercropping Conditions
摘要
Abstract
Under conditions of a large population and limited arable land resources in China,the soy-bean-maize strip intercropping model improves land-use efficiency and crop productivity,helping to mitigate constraints on grain production.To screen out maize varieties suitable for intercropping,five maize varieties('Shaandan 650''Yanke 288''Yudan 896''Zhengdan 958'and'Shaandan 660')were used as materials in the Weibei region.The suitability of these varieties for intercropping was assessed under a soybean-maize 4∶2 planting pattern(maize planting density:75 000 plants/hm2;soybean planting density:150 000 plants/hm2).The results showed that under the 4∶2 soybean-maize inter-cropping system,'Shaandan 650'and'Zhengdan 958'exhibited better overall performance,including more ears per plant,more grains per row,and higher yield.'Shaandan 650'ranked among the top in yield for two consecutive years(10 376.36 kg/hm2,9 716.64 kg/hm2),and had low lodging rate(1.2%-1.65%),demonstrating stronger lodging resistance than'Zhengdan 958'.In this study,maize varieties were suitable for strip intercropping,thereby may help promote the maize-soybean strip interecropping model in the Weibei area.关键词
