通过对河南县高寒草句退化草地封育3年试验表明:轻度退化草地封育3年后的总盖度从78%提高到98%,增加了20个百分点,优良牧草产量增加52.8%,毒杂草产量减少33.1%;中度退化草地封育3年后总盖度从55%提高到79%,增加了24个百分点,优良牧草产量增加96.1%,毒杂草产量减少29.4%;重度退化草地封育3年后总盖度提高了35%,可食杂类草和不可食杂类草的盖度分别提高了25%和7.3%,优良牧草产量增加35.0%,毒杂草产量同时也增加25.5%。

The study showed that the vegetation coverage of mild degraded alpine meadow increased 20 percent point, from 78% improved 98% ,the yield of good pasture increased 52.8%, the yield of poisonous weeds in reduced 33.1% in fencing degraded grassland alpine meadow for 3 years in Henan County. The coverage of moderate degraded alpine meadow increased by 24 percent point,from 55% improved 78% ,the yield of good pasture increased by 96.1%, the yield of Poisonous weeds reduced by 29.4%. For the Severe degraded pas- ture, the coverage increased 35%, the coverage of Edible weeds and Inedible weeds increased 25% and 7.3% respectively, the yield of good pasture increased by 35.0% and the yield of Poisonous weeds increased by 25.5%.
