【摘要】 脱硫石膏改良盐碱地效果与前期灌水量及耕作方式有着密切的关系.本文通过吉林省白城盐碱地整治野外观测科学研究基地,采用不同的灌水量和泡田时间,灌溉时采用起垄灌溉和不起垄灌溉两种耕作方式,来研究最佳灌水量和泡田时间;通过起垄和不起垄灌溉研究对土壤结构及出苗率的影响.更多还原

【Abstract】 The effect of desulfurized gypsum on saline- alkali soil is closely related to the early irrigation and tilling methods. Through the Field Observation and Scientific Research Base of Jilin Province for Saline- alkali Land Renovation,the optimum irrigating quantity,optimum soaking time,soil structure and seedling emergence rate were studied based on ridge irrigation and flat irrigation.更多还原
