间作建立白三叶种子田试验

The Study on Establishing Trifolium repens Seed-breeding Field with Interplanting

在白三叶与鸭茅、多年生黑麦草、大麦3种植物间作的试验中，得出结果为：大麦在苗期及冬春季节对杂草的控制效果较好，以后就失去了对杂草的控制作用；鸭茅能较好地控制杂草，但抑制白三叶的生长；多年生黑麦草与白三叶共生性较好，能长期控制杂草，同时白三叶可获得较理想的种子产量，是白三叶种子生产理想的间作物种。白三叶与多年生黑麦草间作，种子产量511．33kg／hm^2，显著高于白三叶与鸭茅及大麦的间作（P〈0．05）。

On interplanting experiments of Trifolium repens with Dactylis glomerata, Lolium perenne and Hordeum sativum, the result showed that Hordeum sativum can control weeds in seedling stage and winter and spring, later has not this function. Dactylis glomerata can control weeds well but suppresses growth of Trifolium repens. Lolium perenne is perfect interplanting species on Trifolium repens seed production, they can control weeds chronically and their symbiosis is better, simultaneously seed yield of Trifolium repens is higher 511.33 kg/ha, there is significant difference in comparison with interplanting Dactylis glomerata and Hordeum sativum（P 〈 0.05）.
