摘要
本文通过对海南大学农学实习园地近200亩滨海盐土的性质和自然环境进行的多次的调查研究与采样化验分析结果表明:不同部位的土壤含盐量及土层质地的分布,主要受着生物和气候条件的影响。园地中部至南部以1—0.1mm砂粒为主,物理性砂粒大于0.01mm较多;南部0—40cm深度的土壤,在夏季雨水较多时土壤含总盐量为0.15％,而春季雨水较少时则为0.366％。笔者认为滨海盐土利用改良的关键,应着重于开沟引水洗碱和灌溉等行之有效的措施。
This thesis is presented on the base of repeated investigations and researches in the quality and natural circumtance of about 200 mu sea-front salty soil attached to the college of Agriculture, Hainan University The results of chemical examination of its samples indicate that the amount of the containing salt in the soil is mainly affected by the condition of organisms and climate. The sizes of the sands existed in the area from the middle to the south of the farm range from 1—0. 1mm mainly, and a greater portion of the physical sands are bigger than 0. 01mm. The content of salt in the soil in the south, which is 0—40cm in depth, is 0. 15% during the wet summer season, and is 0. 366% during the spring time which has less rainfall. The author concludes that drainage ditches should be dug on the farm to channel water to wash off the salt and to irrigate the soil. This is the key to the improvement and utilization of the farm.
