覆草量对水盐运动影响的实验研究
A Experhoental Study on Effect of Straw Cover Amount on Salt-Water Movement
【摘要】 利用盆钵土壤自动供水装置,定量研究了稻草不同覆盖量对滨海盐土水盐运动的影响。结果表明;覆草量与盆钵土壤日均蒸发量、节水量及表层0~5cm土层含水量和含盐量有一定的定量关系;覆草的节水和抑盐效果分别为每增加0.1kg·m-2的覆草量,抑制蒸发率提高5.92%和抑盐率提高2.57%。
【Abstract】 Through using self-irrigating greenhouse pots, the effect of straw cover amount on saltwater movement was studied quantitatively. The results indicated that there were quantitative relations between straw cover amount and average per-day evaporation capacity, water-saving amount,0 ̄5cm soil water content, 0 ̄5cm soil salt content. With adding 0. 1kg/m2 straw cover amount,the evaporation rate and salt accumtilation rate of restraining increased respectively by 5. 92% and 2. 57%.
