Description

Special fertilizer and application for increasing jasmine fragrance

[0001] The invention belongs to the field of fertilizers, and particularly relates to a special fertilizer and application capable of increasing jasmine fragrance.

Background technique

[0002] Jasminum is a genus of jasmine, whose flowers are elegant and pure. It is a special precious spice crop in China. Jasmine can not only be used to extract expensive jasmine essential oil, but also an important tea raw material. It is an important economically cultivated in north and south of China. One of the crops. Jasmine has good health and beauty effects. Jasmine roots, stems and leaves have medicinal value, sweet and bitter, cool, with heat-clearing and detoxifying, dampness and swelling, promoting blood circulation and dispersing, diuresis and diuresis, and can effectively treat menstruation. Irregular, prostatitis, rheumatism, joint pain, bruises, diabetes, acne and other diseases.

[0003] China is the country with the largest production of jasmine in the world, with annual output accounting for more than 60% of the world's total output. For a long time, Jasmine Garden relies on the application of a large number of chemical fertilizers to increase the production of jasmine. However, due to the unreasonable use of chemical fertilizers and pesticides, environmental pollution has caused environmental aggravation, soil organic matter has decreased, physical and chemical properties have deteriorated, and soil fertility has been greatly reduced. Decrease, the accumulation of harmful substances such as nitrates, heavy metals and pathogenic bacteria is one of the most important factors leading to the weakening of the jasmine flower buds and the deterioration of quality. At present, there are also some special fertilizers for improving the quality of jasmine. For example, Chinese patent CN103130563A discloses a method for preparing jasmine nutrient fertilizer, which comprises rice bran powder, high peel powder, wheat bran powder, black rice flour powder, powder, fish meal, Pig bone powder, lotus root starch, sweet potato powder, vegetable protein powder, animal protein powder, ginseng powder, honeysuckle powder, cassia powder, ginkgo powder, sesame powder, Zhimu powder, rich in nutrients in ingredients, making jasmine strong Jasmine is big, but the special fertilizer uses some rare and expensive animal powder and bone powder to increase the cost, and the simple release of organic fertilizer is slow, which makes the stimulation effect of jasmine not obvious.

[0004] At present, there are few reports on jasmine special fertilizer, and there is no specific fertilizer for increasing jasmine fragrance. The floral aroma of jasmine comes from the volatile aromatic substances produced by the secondary metabolic process of jasmine, mainly esters and alcohols. Its content is very small, but it is the main constituent of jasmine fragrance. The floral scent of jasmine is an important factor in evaluating the quality of jasmine. Therefore, increasing the floral scent of jasmine can increase the economic value of jasmine, but there is no special fertilizer on the market for increasing the jasmine fragrance. [0005] Therefore, according to the growth and fertilizer regulation of jasmine, it is of great significance to research and develop special fertilizers that increase the yield of jasmine and increase the jasmine fragrance.

Summary of invention

technical problem

[0006] The floral scent of jasmine is derived from the volatile aromatic substances produced by the secondary metabolic process of jasmine, mainly esters and alcohols, and its content is very small, but it is the main constituent of jasmine fragrance. The floral scent of jasmine is an important factor in evaluating the quality of jasmine. Therefore, increasing the floral scent of jasmine can increase the economic value of jasmine, but there is currently no special fertilizer on the market for increasing the jasmine fragrance.

Problem solution

Technical solution

[0007] The present invention is directed to the above problems, and proposes a special fertilizer for increasing jasmine fragrance. The special fertilizer provides the required organic matter and large micronutrients for the growth of jasmine. The nutrient content ratio is in line with the fertilizer requirement of jasmine growth, and pyridoxal phosphate, mercaptan, organic acid and surfactant are added to the fertilizer. A fragrant active agent that promotes the synthesis of alcohols and esters with a special aroma in jasmine, making the scent of jasmine more intense. Applying the special jasmine fertilizer can not only increase the yield of jasmine, but also increase the volatile aromatic substances of jasmine, so that jasmine has a strong floral fragrance.

[0008] The technical solution of the present invention is as follows:

[0009] A special fertilizer for increasing jasmine scent, characterized by comprising a special fertilizer comprising the flavoring active agent consisting of the following raw materials: 10 to 15 parts of biochar, 10 to 15 parts of beet pulp, human feces 15~ 20 parts, 5 to 10 parts of gluten, 15 to 20 parts of ammonium polyphosphate, 10 to 20 parts of potassium sulfate, 2 to 6 parts of ferrous sulfate, 1 to 5 parts of borax, 2 to 6 parts of amino acid, soil conditioner 1 to 5 parts, aromatizing active agent 5 to 10 parts; wherein, the flavoring active agent is pyridoxal phosphate, mercaptan, organic acid and surfactant in a mass ratio of 1: 1 to 3: 1 ~ 2: 0. 05~0. 1 composition; wherein the soil conditioner is composed of alginate hydrogel, thiol starch and soil warming agent ammonium mass ratio of 1: 1: 2; One or more of mercaptopropionate, thioglycolate, mercapto mercaptan, thiophenol; the surfactant is polyethylene glycol octylphenyl ether, sodium dodecyl sulfate, Any of sodium dodecylbenzenesulfonate and polyoxyethylene sorbitan fatty acid ester.

[0010] The organic acid is any one of malic acid, tartaric acid, citric acid, shikimic acid, and phenylalanine.

[0011] The preparation method of the special fertilizer for increasing jasmine fragrance of the invention is to firstly decompose and mature the organic fertilizer. After drying, smash, pass 60 mesh sieve; smash the chemical fertilizer raw material and pass 60 mesh sieve, mix with decomposed organic fertilizer, amino acid, soil conditioner and flavoring active agent according to the ratio, and mix the uniform product according to the prior art. The disc is granulated, then dried and sieved, and the sieved product can be packaged and tested.

[0012] The jasmine special fertilizer of the invention is suitable for top dressing application in the flowering stage of jasmine bud. The flowering stage of jasmine is also the stage of formation of volatile aromatic substances. During this period, insufficient fertilizer and water will directly affect the yield and quality of flowers, making the flower petals thin, the oil content lower, the aroma weakening, and causing a lot of buds. The special fertilizer of the invention is applied during the flowering stage of jasmine, and the floral fragrance of jasmine is increased. The specific application method is as follows: The special fertilizer of jasmine is evenly spread on the surface of the soil, and thoroughly mixed with the surrounding soil, and 10-20 kg of special fertilizer is applied per acre of jasmine, and water is poured on the second day after fertilization.

[0013] The main purpose of the jasmine special fertilizer of the present invention is to increase the jasmine flower scent while increasing the jasmine yield. Jasmine can stimulate people's respiratory center, regulate the nervous system, promote blood circulation, and maintain a strong energy for a long time. The floral aroma of jasmine comes from the aroma components released during the opening process of jasmine, mainly a large number of esters and alcohols. Among them, the highest content of esters is benzyl acetate, methyl benzoate and methyl anthranilate. Alcohols mainly include terpene alcohols and aromatic alcohols such as linalool, benzyl alcohol, phenylethyl alcohol and the like. The esters in jasmine are mainly derived from the conversion of amino acids. Under the catalytic action of aminotransferase, amino acids are deaminated and decarboxylated to form aldehydes, and then alcohols and acids are formed. The latter two form corresponding esters under the action of ester synthase. The aromatic alcohol and monoterpene alcohol aroma in jasmine are mainly present in flowers in the form of a glycosidic precursor, which is hydrolyzed by a glycosidase to form a free alcohol to release the aroma.

[0014] Jasmine land is prone to aging, resulting in low soil organic matter content, increased bulk density, imbalance of nutrients, etc. To improve the yield of jasmine and improve the quality of jasmine, soil fertility must be cultivated. Therefore, the special fertilizer of the invention according to the fertilizer requirement rule of jasmine, rationally prepares the nutrient content, provides sufficient organic matter and nutrient elements for the growth and development of jasmine, balances the nutritional condition of jasmine, and increases the yield of jasmine; meanwhile, the soil conditioner is also added to the fertilizer. Optimize the soil environment in which jasmine grows, improve the quality of jasmine, and restore the original scent of jasmine. Alginic acid hydrogel particles and sulfhydryl starch in soil conditioner can make the soil form a porous structure, soft and breathable, improve soil permeability and water retention, enhance soil water and water penetration, promote soil microbial activity, and enhance jasmine disease resistance. Improve the quality of jasmine; also add soil warming agent to increase soil temperature and ensure the normal opening and scent of jasmine.

[0015] The special fertilizer of the invention also adds a flavoring active agent to improve the content of esters and alcoholic aromatic substances in jasmine the amount. The flavoring active consists of pyridoxal phosphate, a thiol, an organic acid, and a surfactant. Pyridoxal phosphate in aromatizing active agent is a coenzyme of amino acid transaminase, which plays a role in the transfer of amino groups in the catalytic process, improves the efficiency of amino acid conversion, and promotes the synthesis of esters in jasmine; thiol substances act as inducing substances to amino acids The transaminase has an activating effect, enhances the catalytic activity of the transaminase, and cooperates with pyridoxal phosphate to promote the conversion of amino acids and increase the content of ester substances. The organic acid provides an acidic environment for the hydrolysis of glycosidase, and the glycoside precursor is rapidly hydrolyzed into a free alcoholic aroma substance; the surfactant can promote the production of glycosidase in jasmine, accelerate the hydrolysis rate, and release the rich fragrance of jasmine, and Its good hydration characteristics are beneficial to the rapid absorption of nutrients by jasmine and the utilization of aromatizing active agents.
