【摘要】 为探究交替耕作对滨海盐碱地的改良效果，在典型滨海盐碱地地区山东省无棣县小泊头镇进行大田试验。设置翻耕与旋耕交替的耕作模式，测定土壤中水盐运移状况和冬小麦产量及其构成。结果表明：交替耕作造成旋耕条带土壤中盐分随着水分的横向运移向翻耕条带聚集，使旋耕条带土壤含盐量比翻耕条带平均降低4.99%，可以减轻旋耕条带盐碱胁迫；交替耕作模式比常规旋耕模式冬小麦产量提高7.00%。交替耕作模式可以在机械条件良好的滨海盐碱地地区推广应用。更多还原

【Abstract】 In order to explore the improvement effect of alternate tillage on coastal saline-alkali land, the field test was carried out in XiaoBotou Town, Wudi County, Shandong Province, a typical coastal saline-alkali land area. The alternate tillage mode of ploughing and rotary tillage was set up to determine the water and salt transport in soil and the yield and constituent of winter wheat. The results showed that: Alternate tillage causes the salt in the soil of the rotary tillage belt to the ploughing tillage belt with the lateral transport of water,which reduces the salt content of the rotary tillage belt by 4.99% compared with that of the ploughing tillage belt, which can reduce the salinity stress of the rotary tillage belt; The yield of alternate tillage mode was 7.00% higher than that of conventional rotary tillage mode.Alternate tillage mode can be applied in coastal saline-alkali land areas with good mechanical conditions.更多还原
