摘　　要：松土补播显著增加天山北坡中山带退化打草场的草层高度、盖度,松土补播优质牧草当年至第3年比对照区依次增加24.64%、123.7%、76.3%;88.9%、111.1%、111.1%。松土补播可以有效提高牧草产量及优良牧草比例,松土补播优质牧草当年至第3年比对照区依次提高173.5%、90.6%、157.2%;57%、73.2%、75%。在松土补播的基础上进行根部施肥可显著增加草层高度、盖度、干草产量,试验当年至第3年比对照区草层高度平均提高57.4%、94.7%、79.38%;盖度依次提高72.73%、70%、72.73%;干草产量依次提高49.93%、56.33%、52.3%。在松土补播的基础上进行叶面施肥对草层高度、盖度的影响显著,当年至第3年分别提高43.5%、189.4%、55.2%;88.9%、111.1%、111.1%。对牧草总产量的影响不显著。对于退化打草场适时刈割对牧草营养的影响不显著。Loosen soil sowing significantly increased the northern slope of Tianshan mountains in Zhongshan with grass height, coverage degradation grassland soil, sowing quality forage was to third years increased respectively by 24.64%, 123.7%, 76.3% than the control area; 88.9%, 111.1%, 111.1%. Loosen soil sowing can effectively improve the forage yield and quality forage percentages, loosen soil sowing quality forage was to third years than in the control area were increased 173.5%, 90.6%, 157.2%; 57%, 73.2%, 75%. Based on reseeding in soil root fertilization can sagnificantly increase the height, coverage, hay yield, the test was to third years with an average of 57.4%, than the control area to improve the height of the grass layer 94.7%, 79.38%; 72.73%, 70%, sequentially improve coverage 72.73%; hay yield were increased 49.93%, 56.33%, 52.3%. Base on reseeding on loose leaf fertilization effect on the height, coverage was significant, and third years respectively increase 43.5%, 189.4%, 55.2%; 88.9%, 111.1%, 111.1%. Effect on forage yield was not significant. For the degraded grassland timely mowing effects on Forage Nutrition is not significant.
