不同改良物料及其配施组合对黄河三角洲滨海盐碱土的改良效果

open access: yesShuitu Baochi Xuebao, 2017
以玉米为研究对象,在盆栽条件下,探究脱硫石膏、蚯蚓粪、硫磺、糠醛渣、沸石对土壤改良的效果,并据此设计改良剂配施组合,研究不同改良剂配施组合对玉米生长发育及土壤性状的改良作用。结果表明:在0—20 cm土层中,脱硫石膏、硫磺、糠醛渣、蚯蚓粪、沸石处理的土壤pH值均有不同程度的降低,轻度盐碱条件下降低了0.05~0.19个单位;中度盐碱条件下降低了0.20~0.33个单位。脱硫石膏可显著降低0—20 cm土层水溶性Na+含量。根据不同改良剂的改良特点,设计了T1(脱硫石膏+硫磺+蚯蚓粪)和T2(蚯蚓粪+沸石+
