Abstract:
Silicone was used as experimental material,and single factor experimental design was adopted.Different proportions of silicone were added into dry soil,0‰，0.15‰，0.30‰，0.45‰，0.60‰ (CK，A1，A2，A3，A4) of dry soil weight respectively,to measure the soil water characteristic curves and evaporation curves,the influence of silicone on soil water availability and evaporation characteristics were explored,in order to provide reference for the improvement of soil water holding characteristics and soil water use efficiency by organic silicon conditioner.The results showed that the soil water content increased with the addition of silicone under the same soil water suction;especially in the range of low suction section (pF 0-2.3) and high suction section (pF 3.0-4.2),and it showed an obvious increase with the increase of silicone application amount.The organic silicon increased the available water and the maximum available water in the soil,while the excess water decreased.The evaporation water loss of silicone treatment was greater than that without silicone treatment,and the more silicone content,the greater water loss of evaporation at the same time.
