研究不同时间套种对玉米生长发育及产量的影响,为玉米适时早套,提高玉米产量提供参考。于5月15、20、25、30日和6月5日共5个播期处理,麦套采用畦埂与套种行2种不同间距的套种方式,观察和测定不同播期玉米的展开叶数、可见叶、种子根数、次生根数、株高、地上部鲜重和干重以及产量。结果表明,共生期间,不同播期玉米的展开叶数、可见叶、种子根数、次生根数播期早的均多于播期晚的,地
The effects of intercropping on the growth and yield of maize at different time were studied to provide references for early maize to improve maize yield. A total of five sowing dates were conducted on May 15, 20, 25 and 30, and June 5, and the two sets of intercropping methods were used in the two sets of intercropping and intercropping. The number of inflorescences of maize at different sowing dates was observed and measured , Visible leaves, the number of seeds, the number of secondary roots, plant height, shoot fresh weight and dry weight and yield. The results showed that during the symbiotic period, the number of leaf unfolding of maize at different sowing dates showed that the number of leaves, the number of seeds and the number of secondary roots sowed earlier than those sowed late,
