sodium layer

Methods: Add sodium chloride injection to the germ layer medium.

方法: 菌层培养基加氯化钠注射液.

The results showed that the total sodium, exchangeable sodium and water-soluble sodium contents in the 0-20 cm soil layer were 10.7-24.6, 48-10250 and 21.5-10400.5 mg/ kg respectively.

结果表明，冀中南棉田土壤0&20cm全钠含量为10.7～24.6gkg；交换性钠含量为48～10250mg kg，水溶性钠含量为21.5～10400.5mg kg。

When using high pressure sodium lamp, the density of squid will increase, the fishing layer will be shallower, and the fishing efficiency will be better, and the average product per hour will be 1 to 6.5 times than before.

采用高压钠灯可以使鱿鱼聚集密度增大，钓捕深度变浅，从而提高渔获效率，其每小时平均产量比采用高压钠灯前高1～65倍。
