Liquid microbial saline-alkaline land improvement fertilizer and preparation method thereof

Abstract

The invention provides a liquid microbial saline-alkaline land improvement fertilizer and a preparation method thereof. The preparation method comprises the following steps: 1) collecting salt crust from a target plant to be improved, and preparing brine from the collected salt crust; 2) uniformly mixing crop straws, kelp powder and peanut oil cakes, spraying the brine to the obtained mixture, adding a fermentation culture product of mixed florae, performing primary fermentation, extracting the obtained primary fermentation solution, and filtering the primary fermentation solution to obtain aprimary fermentation filtrate; 3) drying a primary fermentation solid substance obtained after the filter-out of the fermentation solution, carrying out soaking fermentation in a biogas slurry, extracting the obtained secondary fermentation solution, and filtering the secondary fermentation solution to obtain a secondary fermentation filtrate; 4) mixing the secondary fermentation filtrate and theprimary fermentation filtrate with dry Enteromorpha powder, sunflower disk powder, straw vinegar and starch processing wastewater, adding an EM strain to the obtained mixture, and performing sealing fermentation; and 5) filtering the obtained fermentation solution, collecting the obtained filtrate, and adding indole-3-butyric acid potassium salt and forchlorfenuron to the filtrate to obtain the liquid microbial saline-alkaline land improvement fertilizer.

Description

technical field

[0001] The invention belongs to the soil quality adjustment technology in the field of agriculture, and in particular relates to a liquid microbial salinity-alkali improvement fertilizer and its preparation. Background technique

[0002] There are about 27 million hectares of saline-alkali land in my country, mainly distributed in the northeast, north, northwest inland areas and the coastal areas north of the Yangtze River. Salinization makes the physical and chemical properties of the soil worse, the content of soil organic matter is relatively lower, the nutrient supply conditions are worse, and the activities of soil microorganisms are also inhibited, which has a negative impact on plant growth, resulting in lack of seedlings, reduced production, or even extinction. The main damage caused by saline-alkali environment to plants is manifested in the following two aspects: one is that salt ions will cause physiological toxicity, and plants absorb a large amou...

[0046]The preparation method of the primary filtrate used in the embodiment is as follows: collecting salt crusts from the target area to be improved, and preparing the collected salt crusts into 10% brine.

[0047] Mix wheat, corn, rice, soybean, sunflower, peanut, sorghum and other crop straws and crush them to a size below 1.5cm. According to the mass ratio of 10% brown sugar, 10% lard, 30% bean cake, and 50% honeydew dregs remaining after the honeydew melon seeds are taken, the raw materials are crushed and stirred evenly, steamed with water, cooled and adjusted to 50~ 65%, according to 10% inoculum, add individual strains such as Bacillus lateralis, Bacillus colloidus, Vibrio cellulosum, Bacteroides succinogenes, Pseudomonas fluorescens, etc., at 37°C, in a fermenter alone After fermenting for 4 days, the fermented products of the single strains were mixed, mixed and fermented for another 3 days, and the solid matter was collected to obtain the fermented culture of the mi...

[0050] The ratio is: secondary fermentation filtrate (50%), primary fermentation filtrate (10%), Enteromorpha dry powder (12%), sunflower plate powder (8%), straw vinegar (5%), starch processing wastewater (15%) %).

[0051] Mix the secondary fermentation filtrate, the primary fermentation filtrate with Enteromorpha dry powder, sunflower powder, straw vinegar, and starch processing wastewater, add 1% of EM bacterial agent produced by Mitsubishi Chemical Holdings Co., Ltd. to the resulting mixture, and seal and ferment for 10 days; The fermented liquid is filtered, the filtrate is collected, and 0.25% potassium indolebutyrate and 0.15% forchlorfenuron are added to the filtrate to obtain the liquid microbial salinity-improving fertilizer.

[0052] Dilute the finished product 500 times. Take oil sunflower seeds, soak in the diluent for 24 hours, control treatment 1 seed in deionized water for 24 hours; control treatment 2 seeds ...
