Abstract

The invention belongs to the field of farmland ecological environmental protection, in particular to a method for monitoring soil salinity by utilizing sensitive plants. The method comprises the following steps of: 1) establishing a scientific composite indication system; 2) arranging reasonable monitoring cells and setting a sensitive plant planting method; and 3) analyzing to obtain meaningful judgment results. The method has the advantages that: 1, the traditional situation that the soil salinity is monitored by physicochemical methods is broken, and the influence of factors such as soil texture, carbon nitrogen ratio and microbial community on crop growth under the equivalent salinity condition can be comprehensively reflected; 2, the established sensitive plant composite indication system is simple and effective, does not have requirement on educational background of investigators, is suitable for the research of scientific research personnel and is easily understood and mastered by farmers; and 3, the sensitive plant composite indication method has high economical efficiency, the whole monitoring process can be completed by means of simple equipment such as a ruler and a scale, and expensive instruments and energy are saved.

Description

Technical field [0001] The invention relates to a method for monitoring the degree of soil salinization, in particular to a method for distinguishing and monitoring the degree of soil salinization by using a sensitive plant compound indicator system, and belongs to the field of farmland ecological environmental protection. Background technique [0002] Salinized soil is a type of soil widely distributed in the world. Especially since the second half of the 20th century, with the large-scale and intensive development of irrigation and facility agriculture technologies around the world, it has been caused by excessive irrigation or poor drainage systems. As the groundwater level rises, more and more fertile fields have erupted with secondary salinization. According to incomplete statistics from the United Nations Educational, Scientific and Cultural Organization (UNESCO) and the Food and Agriculture Organization (FAO), the saline soil area in the world is about 95438 million hectar...
