麦玉薯带状种植玉米间大豆的配置方式和品种研究

本文用联合方差和稳产性参数分析法研究了南充地区1986年麦/玉/薯地玉米间大豆配置方式中玉米、大豆、甘薯产量差异显著性、大豆品种的丰产性和稳产性。结果表明,大豆以亩植6000株、玉:豆为2:2、双行玉米两边靠宽行各种一行比对照亩增大豆24.0kg,玉、豆、薯合计增产3.33％,亩产值高24.91元,效果最佳,且对玉米和甘薯均无明显影响。找出了适宣的早、中、晚熟大豆品种,提出了玉米间大豆品种的合理布局。

STUDIES ON THE CULTIVATED FORM AND VARIETIES OF CORN INTERPLANTED WITH SOYBEAN IN THREE CROPPING SYSTEM OF STRIP PLANTING SWEET POTATO AND CORN AND WINTER WHEAT

The productivity and yield stability of soybean varieties and the significance in yield difference of corn and soybean and sweet potato were stndied on the cultivated form of corn interplanted with soybean in strip planting of sweet potato, corn and winter wheat by meen of joint variance and yield stability parameter analytical method, in nanchong Distriotin in 1986. The results showed that effect is better for planting soybean 6000/mu. in the corn row in the ratio of 2 to 2 , with both sides leaned on wide row of two row corn, increasing soybean yield 24.08kg/mu more than that of the Control plots, the total yield of corn and soybean and sweet potato increasing 3.33% and the value of output raising 24.91 yuan/mu. Moreover, no significant influence was laid upon the growing of corn and sweet potato. The suitable varieties of soybean in early and middle and late maturity were found separately The rational layout of corn interplanted with soydean varieties were proposed.
