摘要: 本研究表明,3~5月(萌牙开花期)在柑桔园覆盖地膜,使10~20厘米土层增温2.3℃、土壤含水量提高23.7%、根系活力相对增强4-15%;在9-11月(果实成熟期)覆盖地膜,日平均土温增高1.7℃、土壤含水量比对照降低11-24%。覆膜显著地提高了树冠下层地面的光照反射率,叶片光合能力增强。

Abstract: Mulching plastic film of orchard during March to May (blooming period) increased the soil temperature to 2.3℃ in the depth of 10-20cm soil layer and soil moisture content to 23.7%. The activity of root system was increased to 4-15%. Mulching plastic film from September to November (fruit ripening. period) increased soil temperature per day to 1.7℃, but decreased soil moisture to 11-24%. The rate of reflecting light on the soil surface of low crown sections was largely improved by using mulching plastic film. In addition, the photosynthetic ability of leaves was also strengthened.
