Further, the disclosure is to be construed to cover "from about a low value and / or to about a high value" in a range, even if explicitely not mentioned. Further, the disclosure is to be construed to cover individual values stated in the disclosure even if not stated in the context of a range. Furthermore, when a number of ranges are provided, the disclosure is to be construed to cover each and every combination of these ranges. In other words, unless otherwise specified, all ranges disclosed herein are to be understood to encompass any and all sub-ranges subsumed therein. Specified ranges, including ranges obtained by the combination of any of the other disclosed ranges, are to be interpreted as explicitly disclosed. For example, a stated range of "1 to 10" is to be interpreted to include not only the specifically stated range, but also the implied ranges of greater than or equal to 1 and less than or equal to 10, as well as the individual values 1 and 10. Ranges "about a low value and / or to about a high value" are to be interpreted as explicitly disclosed. Ranges including individual values are to be interpreted as explicitly disclosed. For example, a stated range of "about 1 to about 10" is to be interpreted not only to include the specifically stated range, but also the implied ranges of greater than or equal to 1 and less than or equal to 10, as well as the individual values 1 and 10.

[0019] To solve the above problems, the present application provides a naphthalene acetic acid · amino acid ester granules, by weight percentage, the components include naphthalene acetic acid 0.05-0.1%, amino acid ester 0.1-0.8%;

[0020] Preferably, the components include naphthalene acetic acid 0.1%, amino acid ester 0.4%.

[0021] Preferably, the naphthalene acetic acid · amino acid ester granules, by weight percentage, further include urea 5-60%, ammonium dihydrogen phosphate 20-50%, potassium source compound 30-60%, boric acid 1-10%, zinc sulfate 1-10%, iron source compound the remaining amount.

[0022] The naphthalene acetic acid can promote cell division and expansion, induce the formation of adventitious roots to increase fruit setting, prevent fruit drop, change the ratio of female to male flowers, etc.; amino acid ester promotes the absorption of plants to macro-, medium- and trace elements, increases the content of indole acetic acid, amino acid, etc. in the body; when the naphthalene acetic acid is 0.05-0.1% and the amino acid ester is 0.1-0.8%, they synergize with each other to jointly regulate the endogenous hormones of plants, thereby improving the morphology and physiological characteristics of plants, and further improving the yield and quality. Higher content of naphthalene acetic acid will inhibit the growth of crops.

[0023] Further preferably, the naphthalene acetic acid · amino acid ester granules, by weight percentage, further include urea 5-15%, ammonium dihydrogen phosphate 20-40%, potassium source compound 30-50%, boric acid 2-5%, zinc sulfate 1-4%, iron source compound the remaining amount.

[0024] Further preferably, the naphthalene acetic acid · amino acid ester granules, by weight percentage, further include urea 5-15%, ammonium dihydrogen phosphate 20-40%, potassium source compound 30-50%, boric acid 2-5%, zinc sulfate 1-4%, iron source compound the remaining amount.

[0025] Urea is a high concentration nitrogen fertilizer, belongs to neutral quick-acting fertilizer, also can be used for producing various compound fertilizers. Urea does not remain any harmful substances in soil, long-term application has no adverse effects. But in the prilling, high temperature can produce a small amount of biuret, also known as biuret, has inhibitory effect on crops. Urea is organic nitrogen fertilizer, after hydrolysis into ammonium carbonate or ammonium bicarbonate by urease in soil, can be absorbed and utilized by crops. Urea (nitrogen fertilizer) can promote cell division and growth, make branches and leaves grow luxuriantly.

[0026] The ammonium dihydrogen phosphate is a commercially available product, and the manufacturer is not particularly limited, such as Sichuan Anda Nongsen Technology Co., Ltd., Suzhou Boguili Chemical Technology Co., Ltd.; in this application, the total nutrient (total nitrogen + available phosphorus pentoxide + potassium oxide) of the ammonium dihydrogen phosphate is ≥ 73wt%.

[0027] The potassium source compound includes at least one of potassium dihydrogen phosphate, potassium sulfate, potassium nitrate, potassium chloride; preferably, the potassium source compound includes potassium dihydrogen phosphate and potassium sulfate, the potassium dihydrogen phosphate accounts for 25-30% of the total weight of the potassium source compound, and the potassium sulfate accounts for 70-75% of the total weight of the potassium source compound; preferably, the potassium dihydrogen phosphate accounts for 28.6% of the total weight of the potassium source compound, and the potassium sulfate accounts for 71.4% of the total weight of the potassium source compound.

[0028] The potassium dihydrogen phosphate is a commercially available product, and the manufacturer is not particularly limited, such as Sichuan Anda Nongsen Technology Co., Ltd., Suzhou Boguili Chemical Technology Co., Ltd.; in this application, the total nutrient (total nitrogen + available phosphorus pentoxide + potassium oxide) of the potassium dihydrogen phosphate is ≥ 86wt%.

[0029] Urea is a high concentration nitrogen fertilizer, belongs to neutral quick-acting fertilizer, but the oxygen atom in the urea molecule has a surplus of net charge, and the nitrogen atom relatively lacks net charge, so that the hydrogen atom connected with it is protonated, and easily forms a hydrogen bond with a small amount of water molecules in the air, causing the granules to be severely caked, affecting the use of the product; ammonium dihydrogen phosphate contains nitrogen and phosphorus, two essential nutrients for crop growth, among which nitrogen is an essential nutrient for plant growth, which can promote the growth of crop leaves; phosphorus participates in photosynthesis and respiration in crops, not only can promote the formation and growth of crop roots in early stage, but also can improve the adaptability of crops to external environment; the ammonium dihydrogen phosphate of the present application and urea synergize with each other to improve the yield and quality of crops, but the caking rate of the granules is accelerated after urea and ammonium dihydrogen phosphate are mixed to prepare granules; the present applicant accidentally found that when the potassium source compound includes potassium dihydrogen phosphate and potassium sulfate, and the potassium dihydrogen phosphate accounts for 25-30% of the potassium source compound, the caking rate of naphthalene acetic acid·aminoxin ester granules is 0% after 4 days, which is presumably because the potassium source compound can reduce the activity of hydrogen ions in ammonium dihydrogen phosphate, and promote PO4 3-Form stronger forces with urea, preventing the migration of urea.

[0030] The high content of potassium dihydrogen phosphate can affect the yield and quality of tomatoes, and increase the caking rate.

[0031] The boric acid provides boron, which is one of the essential nutrients for plants. Boron is absorbed by plants in the form of boric acid molecules (H3BO3) and is not easily mobile in the plant body. Boron can promote root growth and has an important role in the synthesis and transport of carbohydrates, the product of photosynthesis, and a special role in the normal progress of fertilization.

[0032] The zinc sulfate provides zinc, which is a special active ion of carbonic anhydrase in plant chloroplasts and can catalyze the hydration of carbon dioxide in photosynthesis. Zinc is also an activator of aldolase and can participate in the synthesis of indoleacetic acid. Zinc can promote the synthesis of indole and serine to tryptophan, which is a precursor of auxin synthesis.

[0033] The iron source compound is selected from at least one of EDTA iron, iron sulfate, ferrous sulfate, and ferrous ammonium sulfate.

[0034] Preferably, the granules further comprise 5-10% of a sulfuric acid compound; the sulfuric acid compound is selected from at least one of modified magnesium sulfate, modified ammonium sulfate, magnesium sulfate heptahydrate, anhydrous magnesium sulfate, ammonium sulfate, and zinc sulfate. Preferably, the sulfuric acid compound is modified magnesium sulfate and ammonium sulfate, and the mass ratio of modified magnesium sulfate to ammonium sulfate is 1:1-2.

[0035] The modified magnesium sulfate is a surfactant-modified magnesium sulfate, which is purchased from Weifang Xinneng Chemical Technology Co., Ltd.

[0036] During the off-season, naphthalene acetic acid and fresh amine ester granules often need to be placed for a long time. Due to the high polarity of the granules, water is continuously absorbed from the air under the action of capillary adsorption force, and then combined with water molecules through electrostatic action and oxygen bonds. In addition, temperature changes promote the alternating changes of the salt crystallization-dissolution process, and the formation of "salt bridge" action between the particles aggravates caking. The applicant found that when the sulfuric acid compound is modified magnesium sulfate and ammonium sulfate, it can limit the outward movement of water in the granules to form a crystal bridge effect, and also prevent water in the air from gathering on the surface of the granules, thereby preventing caking. Thus, the caking rate of naphthalene acetic acid and fresh amine ester granules is less than 15% after being placed for 100 days.

[0037] If the content is too high, the surfactant-modified magnesium sulfate will aggregate, causing the particles to adhere to each other.

[0038] Preferably, the fineness of the modified magnesium sulfate is 80-100 mesh.

[0039] The applicant also finds that when the mass ratio of the modified magnesium sulfate and the ammonium sulfate is 1:1-2 and the iron source compound is EDTA iron, the strength of the naphthylacetic acid · fresh amine ester granules obtained is greater than 40 N, which is presumably that in the process of preparing the granules, the modified magnesium sulfate and the like adsorb part of the free water to convert into crystal water, and at the same time, chelate with other materials to generate a more stable structure.

[0040] The magnesium sulfate can also increase the magnesium element required by crops, and magnesium is an important component of chlorophyll and can promote photosynthesis of crops and growth of plants.

[0041] The second aspect of the application provides a preparation method of the granules, which comprises the following steps: uniformly mixing the components and granulating, so as to obtain the granules.

[0042] Preferably, the preparation method of the granules comprises the following steps: adding naphthylacetic acid, fresh amine ester, urea, ammonium dihydrogen phosphate, a potassium source compound, boric acid, zinc sulfate and an iron source compound into a mixer, stirring and mixing, and extruding and granulating, so as to obtain the granules.

[0043] The granules are used for regulating and increasing yield of wheat, rice, cotton, tea, mulberry, tomato, apple, melon, potato and forest trees.

[0044] The application will be described in detail through examples below. It is necessary to point out here that the following examples are only used for further illustrating the application and cannot be understood as limiting the protection scope of the application, and some non-essential improvements and adjustments made by the person skilled in the art according to the content of the application still belong to the protection scope of the application.
