Abstract
Potato growths have a certain scale in the cultivation of crops in the Shiyanghe River Basin of arid inland river,which is one of the main crops there.In order to promote the application of drip irriga-tion technology,the irrigation system under drip irrigation was carried out on virus-free potatoes.Six soil treatments were treated according to soil moisture content(expressed as the percentage of field capacity). The lower limits of soil moisture content of I and IV irrigation was 45%of the field capacity,and the up-per limit was 75%and 80%,respectively.Besides,the number of irrigation times was four.The lower limit of soil water content of treatment II and V irrigation was 55%, and the upper limit was 75% and 80%of the field capacity,with irrigation times five.The lower limit of soil water content of treatment III and VI irrigation was 65%of the field water holding capacity,and the upper limit was 75%,80%.The number of irrigation times is set to six.The results show that the lower limit of soil moisture content of po-tato that was suitable for growth is no lower than 55%of soil water holding capacity,and the upper limit is 75% ~80%of field water holding capacity,and irrigation times are 5~6,The growth period of vi-rus-free potato Shepody is 120 days,and the irrigation quota was about 3000 m3/hm2.关键词
