辽滨沿海经济区土壤含盐量在0.5%以上,最高含盐量可达3.57%,属于重度盐碱地。本实验以大穴客土法为基础,并制订了淋盐层结合排盐盲管的地下工程措施,结合科学的养护管理,成功地将平均含盐量控制在0.3%以下,有效地控制了盐分对植物生长的影响。
遼濱沿海經濟區土壤含鹽量在0.5%以上,最高含鹽量可達3.57%,屬于重度鹽堿地。本實驗以大穴客土法為基礎,併製訂瞭淋鹽層結閤排鹽盲管的地下工程措施,結閤科學的養護管理,成功地將平均含鹽量控製在0.3%以下,有效地控製瞭鹽分對植物生長的影響。

It was learned that the salt content in soil at the Liaobin coastal economic zone was above 0. 5%, with the highest up to 3.57% , indicating that the land there belongs to the severe saline - alkali land. Adopting the soil re- placement to large cavity method, the experiment successfully controlled the average salt content below 0. 3 % under the scientific maintenance management through underground engineering measure as salt drainage tubes in watering layer, which effectively controlled the impact of salinity to plant growth.
