Alcohol waste liquor-based soil improving and planting method

Abstract

The invention relates to a method which can recycle waste liquor discharged in a molasses alcohol production process in a simple, safe and environmentally-friendly way. Alcohol waste liquor is delivered to a field which is to be ploughed and planted or is planted with crops by a tank truck and sprayed onto the ground; and after being fully contacted with the air, the waste liquor is fermented and oxidized rapidly, so that the effects of fighting against drought, conserving water, enriching soil and improving the soil are achieved and 5 to 15 tons of waste liquor is applied to every mu (666.7 mm<2>) of the field. The method has the characteristics of safely treating the alcohol waste liquor in time, eliminating a sewage treatment system with a high investment, improving the microorganism environment of the soil, enhancing soil fertility and realizing cyclic economy, along with simpleness, practicability, a small number of investments, no environmental pollution and full utilization of the alcohol waste liquor.

Description

[0001] Technical field: The present invention relates to a method for improving soil and its application, which achieves the effect of improving soil through the method of comprehensively utilizing industrial waste liquid. Background technique:

[0002] my country is a country with a wide distribution of deserts and desertification in the world, and it is also one of the countries most affected by desertification in the world. The total area of ​​deserts is 1.28 million square kilometers, accounting for about 1 / 7 of the country's land area. The land area that has been desertified is 176,000 square kilometers, and the land area that is potentially in danger of desertification is 158,000 square kilometers. The desert, Gobi, and desertified land in the northern region have exceeded 1.49 million square kilometers, accounting for about 15.5% of the country's land area. In addition, there are nearly 100 million hectares of saline-alkali land in my country, which seriously restricts t...

Examples

example 1

[0029] Use a filling vehicle to transport the evenly stirred alcohol waste liquid to the unplanted saline-alkali land or desertified land. The concentration of the waste liquid is about 15Bx, and the pH value is 3.5-4.5. The alcohol waste liquid is flooded, and according to the salinity of the land, flood irrigation per mu of land 10-15 tons.

example 2

[0031] Use a filling vehicle to transport the evenly stirred alcohol waste liquid to the saline-alkali land or sandy land where crops have been planted. After dilution, the concentration of the waste liquid is 8-9Bx. tons, and subsequent farming activities can be carried out after application.

example 3

[0033] Use a filling vehicle to transport the evenly stirred alcohol waste liquid to the saline-alkali land or sandy land after harvesting, and the concentration of the waste liquid is 8-9Bx. Composting: Mix sugarcane leaves, bagasse, straw, turf mud and other plant residues, spray 2-3 tons of waste mash on each pile of 5-7 tons of plant fibers, and cover the pile with mud paste. When retting, water once a day. Due to the process of self-fermentation and microbial parasitic reproduction in the heap, after about 30 days of retting, ordinary plant fibers will be turned into high-quality organic fertilizers, which can increase soil fertility after being sprinkled on the spot.
