    摘要:

    根据黄土丘陵区自然环境、社会经济条件,因地制宜地采取与其相适应的水土保持耕作技术措施,以利于蓄水、保土、培肥地力,提高单产,退耕陡坡,还林还草,促使农业生态系统逐渐向良性循环转变。为此,在大面积推广水平沟种植的基础上,进行了覆盖、留茬倒垄、沟内加土挡,坡地草田带状间作轮种、粮草灌宽带间作、川平地覆膜间作套种、深耕密植等水保耕作技术措施的试验研究,并对各种技术措施的蓄水、挡泥、培肥地力、增产增收效益作了评价。

    Abstract:

    According to the national environment,social and economical situation in loess hilly areas,the suitable tillagetechniques with soil and water conservation have been taken. The objectives of storing water,conservating soil,in-creasing fertility and yield,decreasing field in order to plant trees and grasses on slope land,and making the a-griecosystem into favourable circle cap be achieved through applving these techniques. Therefore,on the basis ofplanting. in level furrow in a large range,the experiments have been made to study tillage techniques with soil andwater conservation,which includes covering soil with film;reserving stubble for inversing ridge; putting soil blockin furrow; intercropping and rotation of grass and grain in belt shape and intercropping of grain and grass as well asbush in wider belt on slope land,etc. The benefits of storing water,retainning soil,increasing fertility and yield andincreasing return for every technical measures have been evaluated.
