The invention belongs to the field of organic fertilizer and microbial fertilizer manufacturing, and particularly relates to a saline-alkali soil conditioner and application thereof in the technical field of saline-alkali soil conditioning. The invention provides a saline-alkali soil conditioner. The saline-alkali soil conditioner comprises the following components: a nitrogen fertilizer, a phosphate fertilizer and a synergist. Urea and ammonium sulfate in nitrogen fertilizer of the saline-alkali soil conditioner cooperate with acidizing rhizosphere to promote rhizosphere salinity reduction, different types of phosphatic fertilizers are mixed to improve the fertilizer efficiency of phosphatic fertilizers in salinized soil, and a carbon source and a synergist are matched to strengthen the microbial function of the soil. When the soil conditioner is applied, the activity of soil microorganisms can be stimulated, the soil acidity and alkalinity can be improved, and nutrient turnover can be promoted. When the conditioner disclosed by the invention is applied to the salinized soil, the contents of nitrogen, phosphorus and potassium at the overground part of crops can be increased, and the growth of the crops is promoted.

The application discloses a planting method for improving tobacco quality, and the fertilization mode of the planting method is set as T3, or T4, or T5. The fertilization treatment is beneficial to tobacco plant growth, tobacco carbon and nitrogen metabolism, tobacco leaf quality, and improves tobacco leaf yield.

The application belongs to the field of agricultural biotechnology, and particularly relates to a gene mutant with high potassium absorption and utilization efficiency and application thereof. GhAKT1bD The gene mutant A is obtained by deleting the 111th-114th bases of the wild-type gene, and the gene mutant B is obtained by deleting the 112th-114th bases of the wild-type gene. GhAKT1bD The gene mutant A is obtained by deleting the 111th-114th bases of the wild-type gene, and the gene mutant B is obtained by deleting the 112th-114th bases of the wild-type gene. GhAKT1bD The gene mutant A is obtained by deleting the 111th-114th bases of the wild-type gene, and the gene mutant B is obtained by deleting the 112th-114th bases of the wild-type gene. The transgenic plant provided by the application has excellent low-potassium stress resistance compared with the wild-type plant. In addition, the transgenic plant provided by the embodiments of the application has growth advantages, higher stem potassium content and root potassium content compared with the wild-type plant under the conditions of sufficient potassium supply (2.5 mM) or severe potassium deficiency (0.03 mM).

This invention relates to a method for preparing potassium-enriched soy sauce, comprising the following steps: adding food-grade potassium salts to a fermented and extracted soy sauce base liquid for fortification, so that the potassium content of the final product reaches 3500-4000 mg / 100 mL. (a) Raw material processing: soaking and steaming soybeans, roasting and crushing wheat, and mixing the two; (b) Koji making: inoculating the mixture with Aspergillus oryzae for cultivation to obtain koji; (c) Fermentation: mixing the koji with brine for dilute mash fermentation; (d) Extraction: performing solid-liquid separation on the fermented mash to obtain the soy sauce base liquid. This invention significantly increases the potassium content of soy sauce to approximately 3700 mg / 100 mL, classifying it as a high-potassium fortified food. For people with "low potassium constitution" who do not consume enough potassium in their daily diet, there is no need to deliberately increase the intake of vegetables and fruits; potassium can be conveniently and efficiently supplemented simply through daily cooking and seasoning.

The invention provides a tobacco calcium modulated nerve phosphatase B-like gene and application of the tobacco calcium modulated nerve phosphatase B-like gene. The tobacco calcium modulated nerve phosphatase B-like gene comprises NtCBL1b, NtCBL2a, NtCBL2b, NtCBL3a or NtCBL3b; the nucleotide of the gene comprises: (1) a nucleotide sequence as shown in any one of SEQ ID NO: 2-6; or (2) a nucleotide sequence which is obtained by substituting and / or deleting and / or adding one or more nucleotides to the nucleotide sequence as shown in any one of SEQ ID NO: 2-6 and expresses the same functional protein. Experiments prove that the NtCBL gene is a key gene related to tobacco potassium loss, the potassium content of tobacco can be improved, high-quality tobacco varieties can be cultivated, the quality of tobacco products can be improved, economic benefits can be improved, and the NtCBL gene has good and wide market application prospects.

The invention discloses a nutrient sustained-release acid soil conditioner for facility agriculture and a preparation method thereof. The preparation method comprises the following steps: drying fresh chicken manure, cow dung and sheep manure, crushing until the particle size is less than 1cm, and uniformly mixing the crushed chicken manure, cow dung, sheep manure and snakegourd seed shell powder according to a proper weight ratio; heating to 900 DEG C in an anaerobic environment for pyrolysis, and keeping for 2 hours; and cooling to room temperature, fully grinding, and screening with a 2mm screen to finally obtain the acid soil conditioner. The soil conditioner prepared through interaction of various raw materials not only can increase the pH value of soil and replace traditional lime, but also contains a large amount of organic matter (larger than or equal to 40%), nitrogen (4%) and phosphorus (8%) needed by plant growth, and is a high-quality organic nitrogen phosphate fertilizer. The product is wide in raw material source, rich and cheap in resource, simple in preparation process and suitable for popularization and application.

The invention discloses a method for producing potassium sorbate by liquid-liquid neutralization reaction and continuous cooling crystallization, and belongs to the field of chemical industry. The present invention dissolves sorbic acid in a mixed solvent to obtain a sorbic acid solution, and pumps the sorbic acid solution and potassium hydroxide or potassium carbonate aqueous solution into a neutralization reactor for neutralization reaction to obtain a potassium sorbate solution, and then pumps the potassium sorbate solution into a two-stage crystallization reactor for continuous cooling crystallization, and finally the crystallized tide product potassium sorbate is dried to obtain a potassium sorbate finished product, wherein the mixed solvent is a mixed solvent composed of one or two of ethanol or acetone and water, and the concentration of ethanol or / and acetone is 10%-80%. The present invention dissolves sorbic acid in a solution and reacts liquid-liquid with a potassium hydroxide solution, and the mixing is more uniform and the reaction is easy to control, and the potassium sorbate crystals in the obtained potassium sorbate finished product are regular granular, with a content of ≥99.8% and a transmittance of ≥98.5%.
