一、深松效果黄河三角洲土质结构差,土壤为滨海盐化潮土,土壤盐分随土壤水分季节性移动而呈夏淋、春泛、秋冬稳定的规律性变化。滨海盐土棉田应用土壤深松技术代替传统的浅层犁耕,可以松动深层土体,打破犁底层,增强土体的通透性,促使土壤盐分下淋;同时又可避免犁耕造成土层翻转,保持土壤上部的熟化覆盖层,使棉花根系主要分布区的土层熟化程度和熟土 First, the subsoiling effect The Yellow River Delta soil structure is poor, the soil is coastal salinized soil, soil salinity with the seasonal movement of soil moisture showed Xia Lin, spring pan, autumn and winter stable regular changes. Coastal salt soil cotton soil subsoiling technology to replace the traditional shallow plow, you can loosen the deep soil, breaking the bottom plow and enhance the permeability of the soil to promote soil salinity down; at the same time to avoid soil plowing caused by soil flip , To maintain the maturity of the upper soil cover, so that the cotton root distribution area of ​​the main soil maturity and cooked soil
