Method for resisting water in soil of field experiment plots

Abstract

The invention relates to a method for resisting water in soil of field experiment plots. The method comprises the following steps: (1) determining the total length and the total width of a test field according to the required area of the experiment plots and the length-width ratio of the experiment plots; (2) determining the line space and plot space of each plot according to the step (1); (3) removing the soil between every two lines and between every two plots in the step (2); (4) arranging water-resisting layers among the experiment plots in the step (3), and back filling the removed soil; (5) leveling and compacting the soil between every two lines and between every two plots of each test plot in the step (4); (6) leveling the surface of each test plot in the step (4) and compacting the contact sites between the experiment plots and the water-resisting layers; and (7) covering soil layers which can prevent wind erosion and solar radiation-caused aging and prevent being broken during work onto the water-resisting layers in the step (4). The method provided by the invention does not disturb the field soil, and ensures the natural field soil characteristics, and the objectivity of the experimental study is improved. The materials are easily accessible, and the fabrication cost is low.

Description

technical field [0001] The invention relates to the field of agricultural scientific research, in particular to a method for soil water isolation in a field test plot. Background technique [0002] my country's agricultural water use accounts for more than 60% of the total amount of water used in water resources, of which 90% is used for planting irrigation. At present, the low effective utilization rate of agricultural water in my country is mainly caused by the low production level of agricultural irrigation water. Therefore, soil-plant system water research is an important content in the field of agricultural research. However, due to the difficulty in controlling the soil moisture in farmland (affected by factors such as drought and precipitation), the research results on moisture in the soil-plant ecosystem vary widely. How to improve the quality of the field experiment research platform has become an important way to improve the accuracy of the in-depth research concl...

Problems solved by technology

There is a major defect in this method: that is, the natural structure of the soil is completely destroyed during the operation, and the physical and chemical properties of the soil such as bulk density, porosity, and enzyme activity are changed, and the soil quality is also seriously changed by turning the soil up and down. The soil fertility of the plow layer is completely inconsistent with that of the original soil, and it takes a certain amount of time to cultivate the soil to get close to the original soil quality and structure to meet the test requirements

This will not only cost a lot of manpower and financial resources, but also affect the progress of the test due to time delay
