宁夏荒漠草原改良技术研究
Study on the Improve Techniques in Ningxia Desert Steppe
摘要
Abstract
This study investigated the germination ratio, winter survival ratio, stress resistance, palatability, quality, and yield of 21 varieties of gramineae grasses. The results showed that varieties such as 859, 731, 710, 552, and 616 could be used as fine varieties for range restoration in Ningxia desert steppe. And then, those selected varieties were used for natural range improvement combined with deep plowing, transplant and reseeding recovery technologies. The yield of natural range, plant cover percentage and integrated economic benefit increased 20% and 14.29% to 54.74% , respectively. The pH and salinity of soil decreased slightly and the total mass of micro organism increased. The order of fertility improvement by those technologies were: deep plowing > transplant > reseeding > control treatment.关键词
