| Abstract: |
| Annual Lycium barbarum L. was taken as the object of study in the district of lift irrigation with Yellow River in Jingtai County. The regular irrigation quantity was 5 500 m3／(hm2·a), the material of film, fine sand and straw were used to cover between the lines, and the irrigation with no coverage anything was contract plot. The effects of different measures in water holding and for the growth and fruiting of Lycium barbarum L. were analyzed. The results show that the effects of three types of coverage on soil water content and plant nutrition growth, yield of fruits per plant were that film covering＞straw mulching＞fine sand covering＞comparison. By comprehensive analysis it can be concluded as follows: when film coverage and fixed irrigation per year 5 500 m3/(hm2·a) were used, Annual Lycium barbarum L. can achieved at the purpose of high efficiency, high yield and water-saving. |
