土壤盐分含量以及盐分对作物的危害,前人已做了很多工作,并提出了盐类分级标准。但各地情况不同,常常碰见当土壤总盐量为10%或大于1.0%,按分级标准为强度盐化,按理作物受到严重抑制或不能生长,但事实如何呢?作物生长正常,产量很高,群众反映是一等地。但也有含盐量在0.5%以下者,也没有CO_3=含量,按理作物应该生长正常,但有时却不是这样,只能种一些耐盐能力比较强的作物,如葵花、甜菜、红花等。
Soil salt content and salt damage to crops, many people have done a lot of work, and put forward salt grading standards. However, the situation varies from place to place. When the total salt content in the soil is 10% or more than 1.0%, the grading standard is intensity salinization and the crop is severely inhibited or can not grow. However, what are the facts? Crops grow normally with high yield, The masses reflect first-classly. But there are also salt content below 0.5%, there is no CO_3 = content, rational crops should grow normally, but sometimes it is not the case, only to plant some salt tolerance stronger crops such as sunflower, beet, safflower and so on.
