一般盐碱地,由於含有大量可溶性盐类,土壤溶液浓度高,阻碍植物吸收水分和养分,因而影响正常生长,在发芽阶段各个作物均随土壤含盐量的增高而发芽延迟,发芽率也減低。根据我们研究一般作物在盐土中发芽期盐害的结果。虽然与盐分透过的多少有关系,但主要原因还是因为土壤盐分浓度过大,妨碍种子正常吸水,而造成发芽迟延和发發率低。因
In general saline-alkali soil, due to the high content of soluble salts and high concentration of soil solution, it hinders the plants from absorbing water and nutrients, thus affecting the normal growth. In the germination stage, the germination rate and germination rate of all crops are delayed with the increase of soil salt content. According to our study of general crop salt in the salt germination of the results. Although it is related to how much salt is transmitted, the main reason is that the soil salinity is too large to prevent the seed from absorbing water normally, resulting in delayed germination and low rate of hair growth. because
