specific Embodiment approach 1

[0022] Specific embodiment 1: This embodiment describes a soda saline-alkaline soil nutrition improver for hemp, which includes component A and component B, wherein component A accounts for 50vol.%-90vol.%, B accounts for 10vol.%-50vol.%. Component A is corn steep liquor. Component B contains 10-50 grams of citric acid, 50-150 grams of boric acid, 50-150 grams of amino acid, and 50-200 grams of superphosphate per liter. 1. A mixed solution of 50-150 grams of potassium sulfate.

specific Embodiment approach 2

[0023] Embodiment 2: The soda saline-alkaline soil nutrition improver for hemp as described in Embodiment 1, the corn steep liquor is a by-product produced in the process of producing corn starch.

specific Embodiment approach 3

[0024] Specific embodiment three: a special soda saline-alkaline soil nutrition improver for hemp as described in specific embodiment one or two, the composition of the component A is as follows: Fufeng corn syrup: total sugar 1.0-9.0g / 100g, reduced Sugar 1.0-5.2g / 100g, ash content 1.0-11.0g / 100g, amino nitrogen 0.5-3.0g / 100g, total nitrogen 10.0-30.0g / 100g, lactic acid 1.0-10.0g / 100g, total acid 0.5-3.0g / 100mL , aflatoxin B1<0.2μg / kg, ochratoxin A<1.67μg / kg, zearalenone 10.0-80.0μg / kg, deoxynivalenol<0.03mg / kg, slurry moisture Content 20.0-80.0g / 100g, slag moisture content 20.0-80.0g / 100g, slag yield total acid 0.1-0.8g / 100g; of which, total sugar, reducing sugar, ash, amino nitrogen, total nitrogen, lactic acid and total acid All are calculated on wet basis; slag yield and total acid are calculated on dry basis. The pH of corn steep liquor changes little with the increase of temperature, at 50°C, pH=4.12; at 20°C, pH=4.39; at 4°C, pH=4.50.

Abstract

The invention discloses a soda saline-alkali soil nutrition improver special for China-hemp and a preparation method thereof, belongs to the technical field of China-hemp cultivation, and aims to solve the problem of saline-alkali soil remediation. The nutrition improver comprises a component A and a component B. The component A accounts for 50 vol.%-90 vol.%, the component B accounts for 10 vol.%-50 vol.%, the component A is corn steep liquor, and the component B is a mixed solution of citric acid, boric acid, amino acid, calcium superphosphate and potassium sulfate. The method comprises thefollowing steps: dissolving the citric acid, boric acid, amino acid, calcium superphosphate and potassium sulfate according to a weighed amount, and uniformly mixing; mixing the A and the B at room temperature according to a ratio of (1-9): 1, and uniformly stirring; fermenting at the temperature of 25-35 DEG C for 2-14 days; and before application, uniformly mixing the improver with water according to a ratio of 1-4: 5. According to the method, the nutrition improver and China-hemp planting are effectively combined, the soda saline-alkali soil improvement effect is doubled with half the effort, and the China-hemp fiber yield is increased.

Description

technical field [0001] The invention belongs to the technical field of hemp cultivation, and in particular relates to a soda saline-alkaline soil nutrition improver for hemp and a preparation method thereof. Background technique [0002] Hemp (Cannabis sativa L) is a variety type with THC (tetrahydrocannabinol) content <0.3%, and no drug utilization value. Hemp is easy to grow and does not compete with grain and cotton for land. Therefore, the Chinese hemp industry technology system has shifted hemp production to non-cultivated land (saline-alkali land, hillside land, and winter fallow land), and hemp is used as a crop to improve saline-alkali land. Not only has economic value, but also has ecological restoration value. [0003] Soil salinization has become a global environmental problem. According to incomplete statistics, saline-alkali soil resources are found in more than 100 countries in the world, with a total area of ​​1 billion hectares 2 , of which 99.13 million...
