【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.更多还原

【Abstract】 In this paper,the effects of various mulching patterns on the growth and development of young Lycium barbarum,as well as the changes of soil temperature,were studied.The results showed that the strain diameters under the treatments of mulching by sand,plastic film,straw,were increased by 111.4 %,3.6 % and 38 %,respectively;the plant height increased most significantly under the plastic film mulching,which was 83 cm,followed by the sand mulching;under all the mulching treatments,annual branches of Lycium barbarum grew significantly,especially the sand mulching,under which annual branch grew by 122 cm;the soil temperature raised most obviously under the treatment of plastic film mulching,then the sand mulching.To draw a conclusion,the optimum mulching measure for the cultivation of young Lycium barbarum in high altitude area was sand mulching.更多还原
