Description

Technical Field

[0001] The invention relates to the technical field of compound fertilizers, and in particular to a compound fertilizer and application thereof. Background Art

[0002] Pineapple is one of the famous tropical fruits. It is native to the tropical regions of America and widely distributed between the Tropic of Cancer and the Tropic of Capricorn. It is one of the important fruits in the world. It is cultivated economically in more than 80 countries and regions in the world. The main production areas are concentrated in Thailand, the Philippines, Indonesia, Vietnam, Brazil, South Africa and the United States. China is one of the top ten pineapple producing countries. It is cultivated in Guangdong, Hainan, Fujian, Guangxi, Yunnan and Taiwan in China. Pineapple grows in the tropics. Under the influence of high temperature and heavy rain, excessive rain brings strong leaching effect, which can dissolve and take away almost all soluble minerals, such as potassium, sodium, etc., making the soil lose the nutrients needed by plants and become barren. Therefore, compound fertilizer is generally required.

[0003] Pineapple is rich in nutrition, including carbohydrates, proteins, fats, vitamins A, B1, B2, C, proteolytic enzymes, calcium, phosphorus, iron, organic acids, niacin, etc., especially vitamin C. Among them, the sweetness of pineapple is one of the important quality indicators, that is, increasing sweetness, reducing the sweet-sour ratio, and increasing the fresh taste and flavor. There are few compound fertilizer products in the prior art that can achieve these goals. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a compound fertilizer, which solves the problem that the compound fertilizer in the prior art cannot well increase the sweetness of pineapples.

[0005] According to an embodiment of the present invention, a compound fertilizer is characterized in that it includes, by weight, 500-600 parts of liquid compound amino acids, 150-250 parts of molasses, 55-75 parts of magnesium nitrate, 50-55 parts of zinc nitrate, 15-20 parts of EDTA iron, 3.5-5.5 parts of copper sulfate pentahydrate, 16-17 parts of manganese sulfate monohydrate, 14-16 parts of boric acid, 0.1-0.7 parts of ammonium heptamolybdate, 12-17 parts of glycine, and 50-90 parts of water.

[0006] Further, molasses includes sugar cane molasses.

[0007] Further, molasses includes beet molasses.

[0008] According to an embodiment of the present invention, there is also provided an application of the compound fertilizer, which includes applying it to pineapple.

[0009] Further, drip irrigation is used for application.

[0010] Further, the dilution concentration is 300-500 times.

[0011] Furthermore, the application is carried out by foliar spraying.

[0012] Further, the dilution concentration is 500-1000 times.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The provided compound fertilizer utilizes molasses to chelate divalent cations such as calcium and magnesium to form an organic chelate state, which can meet the pineapple's nutrient needs for trace elements therein and improve the pineapple's photosynthesis efficiency; and molasses contains rich vitamins, minerals, bacterial proteins, nucleic acids, surfactants and growth-promoting factors (bioactive substances), which can promote the growth of pineapples while increasing the vitamins and other nutritional components of pineapples; at the same time, the glycine added in the compound fertilizer synergizes with the sugar in the molasses, which can effectively promote photosynthesis and sugar accumulation, thereby increasing the sugar content of the pineapple and increasing its sweetness. DETAILED DESCRIPTION

[0015] The technical solution of the present invention is further described below in conjunction with embodiments.

[0016] Example 1

[0017] The present embodiment provides a compound fertilizer, including 500g of liquid compound amino acid, 150g of sugarcane molasses, 55g of magnesium nitrate, 50g of zinc nitrate, 15g of EDTA iron, 3.5g of copper sulfate pentahydrate, 16g of manganese sulfate monohydrate, 14g of boric acid, 0.1g of ammonium heptamolybdate, 12g of glycine, and 50g of water.

[0018] Example 2

[0019] The present embodiment provides a compound fertilizer, including 550 g of liquid compound amino acid, 200 g of sugarcane molasses, 65 g of magnesium nitrate, 52.5 g of zinc nitrate, 17.5 g of EDTA iron, 4.5 g of copper sulfate pentahydrate, 16.5 g of manganese sulfate monohydrate, 15 g of boric acid, 0.5 g of ammonium heptamolybdate, 15 g of glycine, and 70 g of water.

[0020] Example 3

[0021] The present embodiment provides a compound fertilizer, including 600 g of liquid compound amino acid, 250 g of sugarcane molasses, 75 g of magnesium nitrate, 55 g of zinc nitrate, 20 g of EDTA iron, 5.5 g of copper sulfate pentahydrate, 17 g of manganese sulfate monohydrate, 16 g of boric acid, 0.7 g of ammonium heptamolybdate, 17 g of glycine, and 90 g of water.

[0022] Example 4

[0023] This embodiment provides a compound fertilizer, which is consistent with the embodiment 1 except for the following contents, except that:

[0024] Replace the sugar cane molasses with jackfruit molasses.

[0025] Example 5

[0026] This embodiment provides a compound fertilizer, which is consistent with the embodiment 2 except for the following contents, except that:

[0027] Replace the sugar cane molasses with jackfruit molasses.

[0028] Example 6

[0029] This embodiment provides a compound fertilizer, which is consistent with the embodiment 3 except for the following contents, except that:

[0030] Replace the sugar cane molasses with jackfruit molasses.

[0031] Example 7

[0032] This embodiment provides a compound fertilizer, which is consistent with the embodiment 2 except for the following contents, except that:

[0033] Contains no cane honey.

[0034] Example 8

[0035] This embodiment provides a compound fertilizer, which is consistent with the embodiment 2 except for the following contents, except that:

[0036] Does not contain glycine.

[0037] Example 9

[0038] This embodiment provides a compound fertilizer, which is consistent with the embodiment 2 except for the following contents, except that:

[0039] Glycine is 7g.

[0040] In the above embodiments, all ingredients are commercially available, and the liquid composite amino acid does not contain glycine.

[0041] Example 10

[0042] The compound fertilizer provided in the above-mentioned Examples 1-9 was applied to pineapples, and the results of different application methods were statistically analyzed, as shown in the following table:

[0043]

[0044]

[0045] Note: The total amount of compound fertilizer applied is controlled at 10kg / mu.

[0046] From the above table, it can be seen that foliar spraying is slightly better than drip irrigation in terms of application method. Specifically, in Examples 1-3, the compound fertilizers provided all made the sweetness of the pineapple reach about 18-21, and Examples 4-6 reached about 16-17. Examples 1-6 were better than Examples 7-9.

[0047] Specifically, both sugarcane molasses and pineapple molasses can promote the sweetness of pineapples, but sugarcane molasses is relatively better;

[0048] At the same time, the use of glycine also affects the sugar content, which may be achieved through the synergistic effect between glycine and sugarcane molasses. The synergy can effectively promote photosynthesis and sugar accumulation, thereby increasing the sugar content of pineapples and increasing their sweetness.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
