Embodiment 1

[0028] A multi-element water-soluble liquid fertilizer, which is prepared from the following raw materials in weight percentage:

[0029]

[0030] The preparation method of above-mentioned multi-element water-soluble liquid fertilizer, its step is:

[0031] First put water and urea into the reaction kettle together, and stir continuously at a temperature of 50°C. After the urea is completely dissolved, add dipotassium hydrogen phosphate, zinc disodium EDTA and boric acid, and continue to keep the temperature ( 50°C) stirring, the solid matter is completely dissolved and left standing to cool to 30-35°C, adding citric acid, stirring until completely dissolved, standing and cooling to 15-20°C, and then taking out the stirred matter from the reaction kettle, which is the The prepared multi-element water-soluble liquid fertilizer.

[0032] For practical application, it can be mixed with water according to the ratio of multi-element water-soluble liquid fertilizer: water volume...

Embodiment 2-7

[0034] A kind of multi-element water-soluble liquid fertilizer of embodiment 2-7 is formulated by the following raw materials of weight percent respectively:

[0035]

[0036] Compared with Example 1, the preparation method of the multi-element water-soluble liquid fertilizer described in Example 2-7 differs only in the temperature of stirring and mixing. Example 2-4 is 45°C, and Example 5-7 is 48°C. ℃, all the other are the same as in Example 1.

Embodiment 2

[0038] The application effect of the multi-element water-soluble liquid fertilizer prepared in Example 2 on radish.

[0039] The multi-element water-soluble liquid fertilizer of the present invention is a new type of water-soluble fertilizer developed by Wuhan Hefengrui Technology Development Co., Ltd. The product mainly contains nitrogen, phosphorus and potassium, and also contains trace elements such as zinc and boron. It has obvious effects on promoting the growth and development of crops, enhancing photosynthesis, improving crop yield and agricultural product quality. In order to explore the application effect of the multi-element water-soluble liquid fertilizer in radish production, the applicant conducted the test from September to November 2008, and the results of the test demonstration are summarized as follows.

[0040] 1. Materials and methods

[0041] 1.1 Experimental design

Abstract

The invention discloses a multi-element water-soluble liquid fertilizer, which is prepared by the following raw materials: water, urea, dipotassium phosphate, disodium zinc ethylenediaminetetraacetate tetrahydrate, boric acid and citric acid in a certain weight percentage. The preparation method comprises the following steps: putting the raw materials into a reaction kettle, continuously stirring at a certain temperature and statically cooling to 15-20 DEG C; and then taking the stirred substance namely the multi-element water-soluble liquid fertilizer out of the reaction kettle. The liquid fertilizer is reasonable in ingredient and convenient to use; the preparation method is simple and easy to operate; fertilization can be performed along with water irrigation; not only water but also the fertilizer is saved; moreover, the labor is saved and cleanness is achieved. The fertilizer causes no pollution to the environment, is low in cost, convenient to use and capable of being directly absorbed by plants without transformation by soil, is used for satisfying the requirements of the plants on nutrient elements, produces effects of growth promotion, rooting, seedling strengthening, flower formation promotion, fruit retention, disease prevention, stress resistance, production increment and quality improvement, and is colorless and tasteless, and widely applied to the fields of agriculture, forestry and the like.

Description

technical field [0001] The present invention relates to the technical field of water-soluble liquid fertilizer, more specifically to a multi-element water-soluble liquid fertilizer, and also to a preparation method of the above-mentioned multi-element water-soluble liquid fertilizer, which can be widely used in vegetables, melons and fruits and field food crops. Background technique [0002] Since the German scientist Haber successfully industrialized ammonia synthesis technology in 1918, the fertilizer industry has developed rapidly since then, which has greatly helped human beings solve the problem of food and clothing. Of course, with the improvement of chemical industry technology, chemical fertilizers have also experienced a series of development processes such as simple fertilizers such as ammonium sulfate and urea, and binary compound fertilizers such as ammonium dihydrogen phosphate. In the middle of the last century, mankind took another big step forward in chemica...
