Problems solved by technology

[0004] However, current domestic research is mainly focused on the extraction, purification and determination of soybean isoflavones, which cannot fundamentally solve the problem of shortage of soybean isoflavone resources. It can be said that increasing the content of isoflavones in soybeans is "a temporary solution and a permanent cure". method, the present invention is to use exogenous induction means to regulate soybean secondary metabolic pathways, so as to achieve the purpose of increasing soybean isoflavone content

preparation example Construction

[0017] The method for preparing above-mentioned foliar fertilizer provided by the invention comprises the following steps:

[0018] In the first step, put the hydrolyzed amino acid into the reactor, add appropriate amount of water, stir and heat, then add salicylic acid, and add ethanol after the temperature is cooled to prepare solution A.

[0019] In the second step, since the methyl jasmonate dry powder needs to be kept airtight and protected from light under normal conditions, use a syringe to draw part of the solution A as a solvent and inject it into the bottle containing the methyl jasmonate dry powder. After shaking and dissolving the methyl jasmonate dry powder, Then suck it out from the bottle with a syringe and mix it with solution A to prepare solution B.

[0020] In the third step, since the sodium nitroprusside dry powder is the same as the methyl jasmonate dry powder, it needs to be sealed and kept away from light under normal conditions, so use a syringe to inj...

Embodiment

[0024] Put 50-80g of hydrolyzed amino acid into the reactor, add 1000g of water, stir 70-120 rpm, adjust the temperature to 50-60 degrees Celsius, add 50-120mg of salicylic acid, add 1-3g of ethanol after the temperature cools down, bottle, sealed, and prepared as Solution A.

[0025] Methyl jasmonate 60-100mg, dry powder, sealed and protected from light.

[0026] Sodium nitroprusside 70-100mg, dry powder, bottled and sealed away from light.

[0027] When in use, take an appropriate amount of solution A and inject it into a closed bottle containing methyl jasmonate dry powder with a syringe, shake and dissolve, suck out the syringe and add it to solution A to prepare solution B;

[0028] Take an appropriate amount of water, inject it into a closed bottle containing sodium nitroprusside dry powder with a syringe, shake and dissolve it, suck it out with a syringe, add it into solution B, and shake it well to complete the foliage fertilizer of the present invention.

Abstract

The invention relates to a foliar fertilizer, which is mixed solution mainly comprising 50 to 120mg / L of salicylic acid, 70 to 100mg / L of sodium nitroprusside, 60 to 100mg / L of methyl jasmonate, 50 to 80g / L of hydrolyzed amino acid and 1 to 3g / L of ethanol, and the pH of the mixed solution is between 6 and 8. A method for preparing the foliar fertilizer comprises the following steps of: putting the hydrolyzed amino acid into water and stirring at a speed of 70 to 120rpm to prepare 50 to 80g / L of hydrolyzed amino acid solution; adding 50 to 120mg / L of salicylic acid at the temperature of between 50 and 60 DEG C, adding 1 to 3g / L of ethanol after cooling and regulating the pH to between 6 and 8 with potassium hydroxide to prepare solution A; adding the solution A into the methyl jasmonate for dissolving to prepare solution B, wherein the addition amount of the methyl jasmonate is 60 to 100mg / L; and dissolving sodium nitroprusside dry powder in water, adding the solution of sodium nitroprusside into the solution B and uniformly mixing to prepare the foliar fertilizer, wherein the addition amount of the sodium nitroprusside is 70 to 100mg / L.

Description

technical field [0001] The invention relates to the field of agricultural production, belongs to the category of fertilizers, and is a foliar fertilizer capable of increasing the content of secondary metabolites of soybean products, especially isoflavones. technical background [0002] Soybean (Glycine max (L.) Merr) is one of the most important crops in my country, especially in Northeast China. Soy isoflavones belong to the isoflavones in flavonoids, which are a type of secondary metabolites formed during the growth of soybeans. In 1993, L. Coward pointed out that soy isoflavones may be the main reason why the incidence of cancer in Japanese is lower than that of Americans, which makes soy isoflavones gradually attract people's attention. H. Adlercreutz (1995) reported for the first time that isoflavones are similar in structure to mammalian estrogen, so they have various physiological activities of estrogen. So far, soybean isoflavones have become the focus of attention...
