摘要
玉米套种高菜是山西省高寒地区的一种新型种植模式。为获得产量和经济效益最大化,于2013-2016年开展了玉米高菜套种的栽培试验(小区试验)和示范(规模化种植试验),研究了二者套作的田间最优配置模式。结果表明:5种处理模式对除穗行数和高菜产量以外的其他玉米农艺性状及产量都有不同程度的影响。其中以处理3模式田间配置最优,即玉米种植密度为67 500株/hm^2,株行距分别为13.5cm、110cm,高菜种植密度为60 000株/hm^2,株行距分别为30cm、55cm;处理3的经济效益最高。
Maize/Brassica juncea var. integlifolia intercropping is a new type of planting pattern in alpine regions of Shanxi Province. In order to obtain the maximum yields and economic benefits, a cultivation experimental plot test （community test） and field demonstration experiment （large scale planting experiment） of maize and Brassica juncea var. integlifolia intercropping were carried out during 2013-2016. The results showed that the five treatments had different effects on the agronomic traits and yields of maize except for the ear rows and yields ofBrassiea jlmcea var. integlifolia. The optimum pattern was T3 treatment which had the densities of 67 500 plants/hm2 for maize and 60 000 plants/hm2 for Brassicajuncea var. integlifolia, and the rows spacing was 13.5cm/110cm and 30cm/55cm, respectively. In the scale cultivation experiment, compared with other treatments, the net income ofT3 was the highest.
