摘要: 为探讨半干旱区旱地地膜覆盖方式对花生田土壤水分、温度及植株生长发育动态特征的影响,测定了不同覆盖方式下,垄作花生各生育时期耕层土壤水分(0-40 cm)、土壤温度(0-25 cm)变化情况。结果表明,(1)覆盖方式影响0-40 cm 土层土壤含水量变化,随生育期推进,各土层和起垄位置土壤含水量均表现“抛物线型”变化趋势;各覆盖方式下,花生苗期垄面处0-40 cm土层含水量明显低于垄沟处,且苗期至开花期垄沟处土壤含水量降幅较大。(2)不同覆盖方式主要通过提高日最高温度来影响耕层土壤温度的变化,花生生长前期,地温受覆盖方式影响强烈,多垄覆盖方式的日最高温度较高,达36.2℃;花生生育后期,地温受覆盖方式的影响较小,开花后,覆盖方式对0-10 cm日地温的影响不明显,但对15 -25cm土层14:00~18:00时地温影响较大,且以L3较高、L0和L1较低。(3)覆盖栽培对花生田土壤14:00时温度影响强烈,可使花生苗期耕层土壤日平均温度升高0.5~2.4 ℃,且最大温差出现在15 cm土层的垄中面花生行间位置。(4)地膜覆盖可增产16.81%~37.17%,水分利用效率提高17.03%~37.42%。常规起垄覆膜双行栽培花生的覆盖方式是较为经济、高效、易耕作的覆盖种植方式。

Abstract: The aim was to study the effect of the different cover modes of plastic film on the soil moisture content , soil temperature in peanut field and peanut growth and development in the semi arid region. The soil moisture in the plough horizon (0-40 cm) and soil temperature in 0-25 cm soil layer were measured in ridge culture under different cover modes of plastic film. The result showed (1) The soil moisture content in 0-40 cm soil layer was affected by different cover modes. The soil moisture content in different soil layer and different ridge position showed parabolic trend with the promotion of growth period. The soil moisture content in 0-40 cm soil layer of ridge side was significantly lower than that of furrow in peanut seedling stage. The decreasing range of soil moisture content from seedling stage to flowering stage in furrow was larger.(2)The soil temperature was affected by increasing the daily maximum temperature under different cover modes. The soil temperature was strongly affected by cover modes during early growth stage of peanut. The highest daily maximum temperature was up to 36.2℃ of multi ridge covering. The soil temperature was less affected by cover modes during late growth stage. The soil temperature in 0-10 cm soil layer was not significant affected by cover mode after flowering, while remarkably affect the soil temperature in soil layer below 15 cm during 14:00~18:00. The soil temperature of L3 was highest , which of L0 and L1 were lower. (3)The soil temperature at 14:00 was significantly affected by mulching cultivation. The soil average daily temperature of plough horizon increased 0.5~2.4 ℃ at seedling stage under mulching cultivation, and the greatest temperature difference appeared at 15 cm soil layer in the middle of ridge. (4) Mulching can improve the yield 16.81%~37.17%, water use efficiency increased 37.42%~17.03%.The ridge film mulching and double row cultivation of peanut is an economical, efficient, easy cultivation method.
