盐碱地种植水稻是改良和利用盐碱地的最有效的措施。大家知道,盐碱地是由于含有过多的盐碱,危害作物生长而需要改良的。种植水稻,田面经常保持有水层,相当于长期冲洗,容易使土壤脱盐。这就是种稻改良盐碱地的优点之一,也是使土壤脱盐的主要原因。根据一些地区的观测资料,在种稻的过程中,特别是在改稻初期,在原始含盐量较重或透水性不良的盐化土上,水稻仍然会在一定的程度上受着盐碱危害的威胁,不过这种危害可以通过一定的措施予以防 Saline-alkali rice is the most effective way to improve and utilize saline-alkali land. As we all know, saline-alkali soil needs to be improved because it contains too much salt and harms crop growth. Planting rice, the field often keep a water layer, equivalent to long-term flushing, easy to desalinate the soil. This is one of the advantages of rice to improve saline land, but also the main reason for soil desalination. According to some regional observation data, in the process of growing rice, especially in the early stage of rice reforming, on the salinized soil with heavy original salinity or poor water permeability, rice will still be affected to some extent by saline-alkali Hazard threat, but this damage can be prevented by certain measures
