盐碱土壤的改良与种植制度是一对互相制约、互相促进的矛盾。对 2 9团场近几年资料的分析结果表明 :不同轮作方式对地下水埋深、土壤含盐率和土壤返盐率均有明显影响。指出合理的轮作方式 ,应在保证当年丰收的同时 ,还应有利于改土治碱的长远目标 Saline-alkali soil improvement and planting system is a pair of mutual constraints and promote each other’s contradictions. Analysis of the data of 29 tenements in recent years shows that different rotation modes have significant effects on groundwater depth, soil salinity and soil salinization rate. Pointed out that a reasonable mode of rotation, should ensure that the current harvest, but also should be conducive to the long-term goal of soil and water conservation
