| Abstract: | Based on the experiment results,combined civil and outside related researches,we discussed the ecological and economic benefits of returning grassland from cropland in the agro-pastoral transitional zone.Returning grassland from cropland could improve the soil physical and chemical characteristics efficiently,utilize rainfall and solar energy more efficiently and increase the economic benefit of soil output.Four kinds of key technology during returning cropland to grassland were put forward:(1) selecting suitable grass species was the base of success;(2) soil selecting and preparation was the key influencing factor of grassland quality;(3) timely planting grass;(4) reasonable management and utilization provided the guarantee of economic and ecological benefits. |
