Problems solved by technology

[0005] Saline-alkali soil has high salinity and high alkalinity, and high-salt osmotic stress causes plant water loss, Na + The accumulation of toxic ions such as ions causes plant cell poisoning, and the high pH value affects the normal growth of plant nutrient absorption; secondly, the soil in saline-alkali soil has poor aeration, sticky structure, large volume, and strong capillary action, which affects plant emergence, root growth and nutrient absorption; finally , the saline-alkali soil itself has low nutrient content, and the high PH value and poor physical structure limit the absorption of nutrients by plants

Embodiment 1

[0035] Preparation of composite organisms organic fertilizer

[0036] (1) Prepare rotten pile: Select pig manure, cow dung, sheep dung and corn straw as composting raw materials for mixing, and make a stack of 1 meter and 1.5 meters wide for oxygen fermentation. Once, 15 days later, 20 days of aging, obtaining rotten and composting;

[0037] (2) Fermented separately, fermentation of Berbalus, yeast, optical bacteria, and lactic acid bacteria separately, and then mixed with fresh fermentation solution of four strains according to the volume of 1: 1: 1: 1 to make composite microbial liquids. The number of bacteria is 6 × 10 8 CFU / ml; the specific fermentation process is as follows:

[0038] Bacillus Berbalus uses an LBG medium (glucose 50g, 10g of protein 胨, 5g of yeast paste, 10g sodium chloride, 1000mll of pure water);

[0039]The yeast uses YPD medium (10g of yeast extract, 20g of protein, 20g of glucose, 1000ml of pure water); the amount of inoculation is 2 %, the cultivation te...

Embodiment 2

[0061] Taking the composite biological organic fertilizer of Formula F for 2 consecutive seasons for wheat planting as treatment 1, the method of the method 1, CK1 and CK2 settings are also the same as Example 1. The result is as follows:

[0062] Table 2

[0063]

[0064] It can be seen that the above -mentioned data can be seen that the composite organic fertilizer of the present invention has a stable reduction of the pH value, reducing the amount of salt content of the soil, and improving the production of crops.

Abstract

The invention discloses a composite bio-organic fertilizer for improving saline-alkali soil and a preparation method thereof, and the preparation method comprises the following steps: mixing pig manure, cow dung, sheep manure and corn straw to prepare a strip stack with the height of 1m and the width of 1.5 m, carrying out aerobic fermentation, and then aging to obtain matured compost; bacillus subtilis, saccharomycetes, photosynthetic bacteria and lactic acid bacteria are respectively and independently fermented to obtain respective fermentation liquor, and then the four kinds of fermentation liquor are mixed to prepare the compound microbial agent. And compounding the matured compost, a compound microbial agent, humic acid, desulfurized gypsum and zeolite to obtain the compound bio-organic fertilizer. The composite bio-organic fertilizer provided by the invention improves saline-alkali soil and also provides nutritional ingredients to promote plant growth.

Description

Technical field [0001] The invention involves the field of compound fertilizer technology, and it is more specifically that it involves a composite biological organic fertilizer and their preparation methods that improve saline -alkali land. Background technique [0002] The area of ​​saline and alkali land around the world is 9543.8 billion hectares, widely distributed in the Americas, Europe, Asia, and Australia. The total area of ​​salt and alkali land in my country is about 99.13 million hectares, mainly distributed in 17 provinces and regions, including the northwest, northeast, North China and Binhai regions, accounting for about 10.33 % of my country's total land area, accounting for approximately one -five -fifth of my arable land area. It includes: native salinized, secondary salt, and various alkaline soils. [0003] Salone and alkali land is a type of land salinized. When the surface layer or sub -surface layer (generally about 20-30cm) water -soluble salts exceeds 0.1...
