Embodiment 1

[0029] Use a graduated catheter to draw 5ml of corn stalk juice with a concentration of 100% and evenly inject it into the soil pan filled with soil, and leave it for two weeks. After the test soil in the soil pan is completely dry, carry out the soil aggregate analysis test . Soil aggregate analysis was performed at the USDA State Key Laboratory of Soil Erosion. The soil aggregate analysis was carried out on the unregulated soil (adding 5ml deionized water) and the adjusted soil (adding 5ml corn stalk juice), and the analysis results showed that compared with the unregulated soil, the adjusted soil The structure was significantly improved, and the soil quality was significantly improved, among which the total amount of soil aggregates increased by 25.62%.

Embodiment 2

[0031] The difference between this example and Example 1 is that 5ml of the juice of rape stalks with a concentration of 100% is applied. The results showed that compared with the unregulated soil, the soil aggregate structure was significantly improved, and the soil quality was significantly improved, and the total amount of soil aggregates increased by 18.49%.

Embodiment 3

[0033] The difference between this embodiment and the first embodiment is that 5 ml of grape stalk juice with a concentration of 100% is applied. The soil aggregate analysis was carried out on the unregulated soil (adding 5ml deionized water) and the adjusted soil (adding 5ml grape stalk juice), and the analysis results showed that compared with the unregulated soil, the adjusted soil The structure was significantly improved, and the soil quality was significantly improved, in which the total amount of soil aggregates increased by 5.86%.

[0034] The test data in the above examples are as Figure 1~4 shown.

Abstract

The invention provides a method for improving the structures of soil granules and increasing the contents of soil aggregates by the aid of juice of corn stalks, juice of rapeseed stalks and juice of grape stalks. The method includes steps of extracting the juice from the corn stalks, the juice from the rapeseed stalks and the juice from the grape stalks; manufacturing soil discs and uniformly applying the extracted juice of the corn stalks, the extracted juice of the rapeseed stalks and the extracted juice of the grape stalks to soil surfaces of the soil discs; allowing the soil with the applied juice to stand still in dry environments. According to the technical scheme, the method for increasing the contents of the soil aggregates has the advantages of practicality and effectiveness.

Description

technical field [0001] The invention relates to a method for regulating soil, in particular to a method for increasing the content of soil aggregates by using pure natural plant stalk juice. Background technique [0002] Soil erosion and soil erosion are global environmental problems that affect human survival and sustainable development. The irrational use of land resources by humans has greatly accelerated the process of soil erosion, making soil, a renewable resource, virtually non-renewable during the development of human society. my country is one of the countries with the most serious soil erosion in the world. In 2005, the Ministry of Water Resources, the Chinese Academy of Sciences and the Chinese Academy of Engineering jointly organized the "Scientific Comprehensive Investigation of Soil Erosion and Ecological Security in China" expert group pointed out that soil erosion is a concentrated reflection of various ecological problems in my country, and it is also the r...
