Problems solved by technology

These nutrients can play an important role in promoting the growth and development of sugar beets. If they are directly discharged into water bodies, they will cause serious pollution and a great waste of resources.
[0003] However, there is no specific treatment method for the yeast concentrate in the prior art. Many enterprises directly discharge the yeast concentrate with sewage or directly irrigate the farmland with the yeast concentrate, which not only pollutes the water environment, but also pollutes the land.
The specific reasons are: (1) the yeast concentrate itself has a certain stench. If it is applied to the ground without treatment, the stench will disperse and affect the environment; (2) the COD content of the yeast concentrate is relatively high, such as Without treatment, it will aggravate land pollution and affect the growth of crops; (3) Yeast concentrate has high salt content, if it is not treated, it will aggravate soil salinization
And if the yeast concentrate is directly used for farmland irrigation without compounding according to the nutrient requirements of the crops, the crops are prone to deficiency diseases

Embodiment 1

[0058] A special liquid fertilizer for sugar beet prepared by using yeast concentrate, which is prepared by the following method:

[0059] (1) Add sulfuric acid solution to the yeast concentrate, stir and react to obtain the first reaction liquid;

[0060] Among them, the mass percentage concentration of the sulfuric acid solution is 25%, the volume ratio of the yeast concentrate to the sulfuric acid solution is 8:1, and the reaction time is 0.5h.

[0061] (2) Pass the EM bacterial solution into the first reaction solution, and then perform fermentation and aeration treatment at 25-30°C for 5.5 hours under light conditions to obtain the second reaction solution;

[0062] The EM bacterial liquid contains lactic acid bacteria, Bacillus subtilis, Bacillus licheniformis, yeast, nitrifying bacteria, photosynthetic bacteria and carriers, and the effective number of viable bacteria is ≥10 billion / g. The mass ratio of the first reaction liquid to the EM bacterial liquid is 100:0.3. The EM ba...

Embodiment 2～6

[0070] The preparation process is basically the same as that of Example 1. The products include special flush fertilization during the luxuriant period of sugar beet leaves and special flush fertilization during the growth period of sugar beet roots. The changed parameters are shown in Table 1.

[0072] Example Variable parameters Example 2 In step (1), no sulfuric acid solution was added to the yeast concentrate, and other preparation processes were the same as in Example 1. Example 3 In step (2), no EM bacteria liquid was added, only aeration treatment was performed, and other preparation processes were the same as in Example 1. Example 4 No synergist is added in step (4), and other preparation processes are the same as in Example 1. Example 5 In step (5), ammonia was not used to adjust the pH value to 6-7, and other preparation processes were the same as in Example 1.

experiment example

[0074] 1. The purpose of the experiment

[0075] Using the yeast concentrate liquid fertilizer for sugar beet prepared in the embodiment of the present invention, field experiments were conducted at the Baihuisheng R&D Center Experimental Base of Linxi County, Chifeng City, Inner Mongolia, to identify the effect of the liquid fertilizer on sugar beet, yield and disease resistance.

[0076] 2. Overview of the experiment

[0077] The field management of the test field was carried out in accordance with standardization, including planting and transplanting, drip irrigation under the film, and timely prevention of diseases, insects and weeds. The sugar beet variety is Syngenta HI0936, the beet spacing is 26cm, the row spacing is 50cm, and 5000 seedlings are protected per mu.

[0078] 3. Experimental design

[0079] In this experiment example, the experimental group and the control group are set, and each group is set to repeat the experiment three times. The setting method is as follows...

Abstract

The invention provides a special beet liquid fertilizer prepared from yeast concentrate. The special beet liquid fertilizer is prepared by a method including the steps: (1) adding sulfuric acid solution into the yeast concentrate and performing stirring reaction to obtain first reaction liquid; (2) performing aeration treatment on the first reaction liquid to obtain second reaction liquid; (3) naturally precipitating the second reaction liquid by standing to obtain precipitates and suspension liquid; (4) dissolving the suspension liquid, fulvic acid, urea, potassium sulphate, monoammonium phosphate, monopotassium phosphate, borax, chelated zinc, ammonium molybdate and synergists in water to obtain the liquid fertilizer. The yeast concentrate is prepared into the special suitable for beet growth, the problem of water environment pollution caused by the yeast concentrate is solved, the requirements of beets for nutrients in all growth periods can be met, and the nutrients taken away by the beets in the growth process are returned to lands. Moreover, waste can be comprehensively used and turned into wealth, and the environmental protection pressure of enterprises is relieved.

Description

Technical field [0001] The invention relates to the technical field of compound fertilizers, in particular to a special liquid fertilizer for sugar beet prepared by using yeast concentrate. Background technique [0002] Using sugar beet as the raw material, the remaining substance in the sugar making process is beet molasses (beet molasses), which is a dark brown viscous liquid with a dry matter content of 72%-88.8%. Its main components are Sugars, including natural sucrose, glucose and fructose, have a content of 30% to 50%. Beet molasses is the raw material for fermented production of dry yeast powder or yeast extract and other products. After using molasses as raw material to produce dry yeast powder or yeast extract, the remaining waste liquid is yeast concentrate. Yeast concentrate is a high-concentration organic wastewater, with a pH of 5.8-6.5, COD about 40,000 mg / L, and BOD about 20,000 mg / L. Because the yeast concentrate contains a lot of amino acids, organic matter, m...
