桑树的耐盐碱程度与大多数田间作物大致相似,土壤含盐量在0.2%以下时都可栽植。实践表明,表土含盐量在0.15%时栽桑成活率达95%。一般盐碱土经改良降低到0.3%以下即可栽桑。栽桑时,必须掌握盐碱的变动规律,采取有效的排盐措施。一、翻土脱盐平整、深翻土地,可促进脱盐。土地平整,可使灌水或降水分布均匀,减少地面径流,使盐分不易集中于地表。土地经平整后还可把含盐量 The degree of salt-tolerance of mulberry trees is similar to that of most field crops. When the salt content of soil is below 0.2%, it can be planted. Practice shows that topsoil salinity rate of 0.15% when planted mulberry survival rate of 95%. Salt and alkali soil generally reduced to 0.3% below can be planted mulberry. When planting mulberry, we must master the changes of saline and alkali, and take effective measures to drain salt. First, the soil desalination formation, deep turning the land, can promote desalination. Land formation, irrigation or precipitation can be distributed evenly, reducing surface runoff, so that salt is not easy to focus on the surface. After the formation of the land can also salinity
