| 摘 要： | 用正交试验方法，通过除杂、施肥，补播等综合措施，对因杂草侵入，缺水缺肥，利用过度而导致建植草种过早丧失生产性能的“多年生黑麦草－白三叶”人工草地进行复壮试验，结果表明，施肥是较有效的复壮措施，牧草产量提高６５．４％；１００％除杂，施用尿素１５０ｋｇ／ｈｍ＾２，普钙１０５ｋｇ／ｈｍ，硫酸钾３０ｋｇ／ｈｍ＾２，松土撒播多年生黑麦草种子１３．５ｋｇ，白三叶草籽４．５ｋｇ为最佳技术组合，２年平均其牧草产量

| Abstract: | Comprehensive technique such as killing weeds, over seeding, fertilizing were used to recover the degenerated perennial ryegrass white clover grassland. The results showed that the fertilizing could increased herbage yield by 65%. Applying 150 kg CO(NH 4)/hm 2, 105 kg Ca(H 2PO 4)+CaSO 4/hm 2,30 K 2SO 4/hm 2, overseeding 13.5 perennial ryegrass and 4.5 white clover/hm 2 were the best technical constitution. As a result, yield, cover and height of herbage increased by 2.13 times, 71% and 31.2 cm respectively. |
