Problems solved by technology

However, there are still some problems in the influence of water-retaining agents on soil, such as how the application of water-retaining agents affects the mechanism of soil aggregates, how does water-retaining agents affect soil infiltration, and the application of water-retaining agents for different regions The type, method of administration, and dosage are all unknown
[0009] To sum up, there have always been problems such as high pollution, high energy consumption per unit of machine farming, high additive dosage, and unfavorable environmental protection related technologies for suppressing soil water evaporation.

[0082] 2) Test plan

[0083] The inspiration of the present invention comes from Chinese opera pasting film technology. In order to fix the hair bun on the head and face, danjiao actors often soak the inner fibers of the elm bark after removing the outer skin (that is, horny hard skin) with boiling water, and the elm fiber is soaked in boiling water. After soaking, a gel will be produced, which has the characteristics of moisture ...

Abstract

The invention provides a method for reducing soil moisture evaporation by using elm powder. The method comprises the following steps: mixing elm powder into surface soil to obtain soil containing elmpowder with a certain concentration; and adding a certain amount of water according to a preset water content to prepare unsaturated soil to be evaporated. According to the method, the application amount of the elm powder calculated according to the elm powder concentration of 0.01%-0.03% is 9-27 kg / mu, the elm powder is applied to cultivated land soil according to the application amount, and thewater saving efficiency is 10.348%-12.108%. According to the method, the elm powder serves as the soil anti-evaporation additive, the purpose of achieving high water-saving efficiency through the low-concentration additive is achieved, the method has the advantages of being low in cost and small in use amount, and the method further has the advantages of being wide in raw material source, free ofpollution, capable of improving soil fertility, high in stability and the like.

Description

technical field [0001] The invention relates to the technical field of agricultural water conservancy engineering, in particular to a method for reducing soil water evaporation by using elm wood powder. Background technique [0002] Soil moisture is the link and central link between the land and the atmosphere, and participates in processes such as surface water cycle, energy and momentum exchange, and is an indispensable key parameter in ecosystems and climate systems. Especially in arid and semi-arid regions, soil moisture is an important indicator that can characterize the soil conditions in arid regions. It affects the growth, distribution pattern and evolution process of vegetation, and can also reflect and explain the degree of soil weathering. Soil water evaporation is an important part of soil water balance, and it is the process of soil water diffusion at the soil-atmosphere interface. The evaporation process is a complex process that occurs inside the porous mediu...
