摘要
Abstract
Through the study of ecological restoration measures for extremely severely degraded grassland types and no-tillage reseeding tech-niques,the research further provides ecological reseeding recovery technical support for the degraded and desertified grasslands in northern Xi-zang.In the abandoned wasteland surrounding the towns of Nagchu,a trial of mechanized ecological restoration through no-tillage reseeding was conducted.The no-tillage reseeding machinery created furrows about 5 cm deep and spaced 20 cm apart.The seed and fertilizer hopper of the no-tillage reseeding machine mixed organic fertilizer with perennial seeds such as alkali grass and bluegrass at a ratio of 1∶2 for sowing.After sowing,the soil was covered by a rake-like attachment at the rear of the machinery,achieving full mechanization throughout the process.The results showed that by using suitable perennial varieties for mechanized no-tillage reseeding,the coverage rate of edible pasture vegetation in the abandoned wasteland increased from 0 to 64.78%.Additionally,the seedling emergence rate of pasture grasses through me-chanical no-tillage reseeding was 29%higher than that of manual reseeding.关键词
