Embodiment 1

[0031] The pre-calculated corn stalk juice was evenly applied to the soil surface of the test soil tank according to the concentration of 100% (400g, 800g). Place it for 1 week, wait for the test soil to dry and then conduct a simulated rainfall test. During the rainfall process, 50mm / min rainfall is used for 60 minutes, and a runoff full sample is taken every 5 minutes, and then switched to 25mm / min rainfall for 20 minutes, and a runoff full sample is taken every 5 minutes. , then switch to 75mm / min rainfall for 10min, take a full runoff sample every 3min, then switch to 100mm / min, take a full runoff sample every 3min, the whole test lasted 100min. After the test, weigh the test runoff sample, then add alum water to precipitate for 24 hours, then pour off the supernatant liquid, put the runoff sediment sample after pouring out the supernatant liquid into a large oven, bake at 105°C for 24 hours, and wait for thorough drying After that, take it out and weigh it. The runoff se...

Embodiment 2

[0033] The difference between this embodiment and the first embodiment is that the concentration of the applied corn stalk juice is 75% (300+100g, 600+200g).

Embodiment 3

[0035] The difference between this embodiment and the first embodiment is that the concentration of the applied corn stalk juice is 50% (200+200g, 400+400g).

Abstract

The invention provides a method for preventing soil water erosion by means of juice of maize straw. The method includes the following steps of (1) extracting, wherein the juice is extracted from the maize straw, (2) applying, wherein the extracted juice of the maize straw is applied to the surface of soil and (3) standing, wherein the soil where the juice is applied stands in a drying environment. According to the method, the problem of how to provide a practical and effective method for preventing soil water erosion is solved.

Description

technical field [0001] The invention relates to the fields of desertification prevention and restoration and ecological environment restoration, in particular to a method for preventing and controlling soil water erosion by using corn stalk juice. Background technique [0002] Water erosion desertification is land degradation caused by water and soil erosion. It is an important form of desertification and the most serious ecological environment problem that our country is currently facing. Serious water erosion and desertification lead to land decline, frequent disasters, river reservoir siltation, water quality deterioration, and water shortage, which seriously restrict the sustainable use of resources and environment and the sustainable development of social economy. It is an important ecological and environmental problem to be solved urgently in my country. . The results of the fourth national monitoring of desertification and sandification show that by the end of 2009, t...
