灌水量对膜下滴灌水稻土壤水盐分布及产量的影响
Effect of Irrigation Amount on Soil Water-salt Distribution and Rice Yield under Mulched Drip Irrigation
摘要
Abstract
Field experiments under mulched drip irrigation were carried out in order to analyze the characteristic of soil water-salt movement and rice yield.The results showed that soil water contents of 0～20,20～40 cm layer below film under different irrigation amounts were the highest in the whole rice growth.Soil water contents of 0～60 cm layer under films and 0～60 cm layer between films were the highest when the irrigation amount was the top in the jointing stage to the flowering stage.There was the highest desalinization efficiency in the 0～40 cm layer under film while soil salt was accumulated in 40～60 cm layer under film.The effect of irrigation amount on yield was significant,and the rice yield was higher with higher irrigation amount.关键词
