福建部分酸化障碍土壤的pH、ORP、EC理化性质及其土壤结构调理
|
Abstract:
福建地处中国南方亚热带,由于人们长期的土壤利用缺乏科学理论指导引发了部分土壤出现严重障碍问题。本文选取了福建省内10处酸化障碍土壤作为实验研究基地,进行了土壤pH值、氧化还原电位(ORP)、电导率(EC)等理化性质的跟踪测定,发现酸化土壤的pH值低下,同时出现ORP异常及EC偏低等问题,通过采用泉州市洋屿土壤科技有限公司生产的土壤结构调理剂进行调理改良,历经2年实验及4季作物的轮作,酸化障碍土壤的pH、ORP和EC都得到逐步恢复并趋向正常范围。
Due to the lack of scientific theoretical guidance on long-term soil utilization, some soils have serious obstacles in Fujian Province where is located in the subtropical climate zone of southern China. Based on 10 acidified obstructive soils in Fujian Province as experimental bases, the measurements of soil pH, oxidation-reduction potential (ORP), electrical conductivity (EC) and other physicochemical properties were investigated and tracked concurrently. It was found that the pH value of the acidified soils was below the normal value, and there were also problems such as abnormal ORP and low EC. Soil structure conditioners produced by Quanzhou City Yangyu Soil Technology Co., Ltd. were employed for conditioning and improvement of the acidified soils. After 2 years tests and 4 crop rotations, the pH value, ORP, and EC of the acidified obstructive soils had gradually recovered and tended to the normal ranges.
