摘　　要：研究了不同覆盖方式对幼龄枸杞生长发育和土壤温度变化的影响.结果表明:砂子、地膜和秸秆覆盖与露地处理相比,幼龄枸杞株径分别增长了111.4%、3.6%和38.0%;枸杞株高增长最为明显的是地膜覆盖,增长了83 cm,砂子覆盖次之;在砂子、地膜和秸秆覆盖方式下,幼龄枸杞的一年生枝与露地相比,都有大幅度的增长,最显著的是砂子覆盖,增长122 cm;地温升温效果最明显的是地膜覆盖,砂子覆盖次之.In this paper, the effects of various mulching patterns on the growth and development of young L ycium that the strain 111.4 %, 3.6 film mulching, barbarum , as well as the changes of soil temperature, were studied. The results showed diameters under the treatments of mulching by sand, plastic film, straw, were increased by and 38 %, respectively; the plant height increased most significantly under the plastic which was 83 cm, followed by the sand mulching; under all the mulching treatments, annu al branches of Lycium barbarum branch grew by 122 cm; the soil grew significantly, temperature raised mulching, then the sand mulching. To draw a conclus especially the sand mulching, under which annual most obviously under the treatment of plastic film ion, the optimum mulching measure for the cultiva-tion of young Lycium barbarum in high altitude area was sand mulching.
