摘要
天峻县"黑土滩"型退化草地分布广,面积大,需要科学经济适宜的植被恢复措施,以推进全县退化草地治理工作。本文以舟群乡四村社"黑土滩"为例,针对其退化现状和土地条件,因地制宜的从选择优良品种和建植时节,规范建植技术入手,在坡度小地段采用机耕,在坡度大地段采用畜蹄法镇压等措施治理退化草地。建植后治理区出苗率达≥45%,成活率≥90%,越冬率≥96%,草地产量(次年)2034kg/hm^2,生态功能得到逐渐恢复。
As the "bare land"of deteriorated grassland in Tianjun county is distributed widely and has a large area,it needs a scientific and economical re-vegetation mode to promote the management of deteriorated grassland in the whole county. Taking the "bare land"in Sicuan Community,Zhouqun Village as a case,focusing on the degradation situation and land condition of it,this research selects the fine varieties and planting time according to circumstances. Starting from the standardization of planting technology,this research adopts the way of tractor-ploughing in areas with small slope and adopts the method of plow( hoof-repression) in areas with large slope to manage the deteriorated grassland.After planting,the emergence rate of plants in the management area is or even more than 45%,the survival rate is or more than 90%,the wintering rate is or more than 96%.In addition,the output of grassland( in the next year) is 2034 kg/hm2 and the ecological function has gradually recovered.
