Abstract

This invention relates to one plant tar paper process method to prevent water and saline-alkali, which can prevent earth water infiltration and down earth saline alkali rising. The invention is processed by plant materials with low poison and biological degradation used for saline alkali improvement and roof anti-water.

Description

Technical field: [0001] The invention relates to a preparation method of plant tar paper which is waterproof and prevents the penetration of saline-alkali components, and is mainly used for the improvement of saline-alkali land and sand leakage land. Background technique: [0002] my country is a large agricultural country, and agricultural development is one of the important components of national economic development. However, at present, more than 80% of the cultivated land in my country has obstacles such as drought, low-lying areas, and salinity, which require different degrees of conditioning and improvement. Problems such as soil erosion, soil desertification, soil salinization, and soil pollution are emerging one after another. Studying effective measures to control problematic soils, improve soil conditions, and control the further improvement of ecosystems will be a major event related to the growth of our national economy, and it is also an important measure for o...
