Embodiment 1

[0023] Bacteriostatic effect of carboxylic acids (including substituted carboxylic acids)

[0024] We tested the bactericidal efficacy of a large number of carboxylic acids (including substituted carboxylic acids) by disc diffusion method on agar plates inoculated with spoilage microorganism E. coli. After a lot of screening work and experimental verification, it is proved that some carboxylic acids and carboxylates (including substituted carboxylic acids or substituted carboxylates) have antiseptic effects on spoilage bacteria and antibacterial at a certain concentration. These substances include acetic acid, acetate, diacetic acid, diacetate, dehydroacetic acid, dehydroacetate, oxaloacetate, oxaloacetate, propionic acid, propionate, acrylic acid, acrylate, Malonate, malonate, hydroxypropionate, hydroxypropionate, succinate, succinate, pyruvate, pyruvate, citric acid, citrate, malic acid, malate, etc., and these Mixture of ingredients. The bactericidal effect is most signif...

Embodiment 2

[0030] We took fresh cut flowers and yeast isolated from soil as the experimental objects, and tested their absorption and decomposition effects on carboxylic acids (including substituted carboxylic acids). The results show that acetic acid, diacetic acid, dehydroacetic acid, oxaloacetic acid, propionic acid, acrylic acid, malonic acid, hydroxypropionic acid, succinic acid, pyruvic acid, citric acid, malic acid, etc. have a certain absorption and decomposition effect. The concentration of carboxylic acid (including substituted carboxylic acid) during absorption and decomposition, the total concentration of the above-mentioned relatively small molecular weight acetic acid and hydroxypropionic acid is preferably below 0.002M; while the total concentration of relatively large molecular weight components is preferably 0.001M the following.

[0031] Hereinafter, acetic acid and hydroxypropionic acid with small molecular weights are taken as examples to describe in detail below.

Embodiment 3

[0041] In the 500ml aqueous solution that added concentration is 0.1M acetic acid 5ml and 0.1M hydroxypropionic acid solution 5ml, and MS biological culture fluid 5ml, add soil separation yeast solution 5ml (concentration is about 10 5 Individual / ml), the concentration of carboxylic acid in the solution was measured at the time, 1 day and 5 days after adding the soil-isolated yeast.

[0042] As a result of the detection, the concentration of carboxylic acid in the solution was measured at the time, 1 day and 5 days after adding the soil to isolate the yeast: 2mM, 0.5mM, 0M. It shows that under the above conditions, acetic acid and hydroxypropionic acid have been gradually absorbed and decomposed by yeast isolated from soil.

[0043] And adding concentration is 0.2M acetic acid 5ml or 0.2M hydroxypropionic acid solution 5ml, and in the 500ml aqueous solution of MS biological culture fluid 5ml, add soil separation yeast solution 5ml (concentration is about 10 5 Individual / ml), ...

Abstract

The present invention relates to a plant nutrient active agent, it is an aqueous solution containing several components. It is characterized by that it contains at least two preservative components, the described preservative component is carboxylic acid or carboxylate containing no benzene ring, and its concentration is not less than 0.001 mole / L. The described preservative component can be two kinds or more than two kinds selected from acetic acid, acetate, diacetic acid, diacetate, dehydroacetic acid, dehydroacetate, oxaloacetic acid, oxaloacetate, propanoic acid, propionate, acrylic, acid, acrylate and others.

Description

technical field [0001] The invention belongs to the field of plant liquid preparations, and in particular relates to a plant nutritional active agent. Background technique [0002] In plant cultivation, especially in the cultivation process of potted plants, it is necessary to use various preparations to supply, strengthen or balance plant nutrition, enhance plant activity and health, improve plant immunity, disease resistance and resistance to various adverse effects. Environmental tolerance, and improve and adjust soil properties. In the prior art, various organic and inorganic ingredients, natural nutrients, and soil improvement ingredients are formulated into plant nutrition active agents with aqueous solutions, mostly containing nitrogen, phosphorus, potassium, calcium, magnesium, boron, manganese, sulfur, iron, Nutrient elements needed by plants such as zinc, copper, iodine, cobalt, and molybdenum have been widely used in plant cultivation. However, the above-mention...
