Problems solved by technology

[0002] Multi-element liquid fertilizers are widely used in the growth period of crops. By compounding multiple elements, various nutrients needed by crops can be supplied at the same time. However, the multi-element fertilizers currently on the market have the following problems: (1) There are few types of compound elements: when compounding more When there are several elements, only by simple mixing, there may be undesired compound reactions among various elements during the preparation or storage (such as producing color, sediment or suspended matter, affecting the absorption of crops), thus affecting the quality of the final product. Characters and performance, based on this consideration, the types of multi-element liquid fertilizers are limited for crops, and are not suitable for wide application; (2) Low element content: the solution specific gravity of ordinary products is only about 1.1; (3) Poor stability: the commercially available The storage time of multi-element liquid fertilizer is short, and the properties of the solution are easy to change after a long time of storage. Suspended solids, sediments or color changes appear, and the content of elements is greatly reduced compared with the original label.
(4) Poor adhesion: it is easy to be washed away by rain, so an adhesive has to be added to improve the adhesion of liquid fertilizer to the leaf surface

[0061] A Field Fertilizer Efficiency Test of Early Rice Application of Multi-element High-Concentration Liquid Fertilizer (Example 6)

[0062] 1. Materials and methods

[0063] 1. Test fertilizer: the multi-element high-concentration liquid fertilizer obtained by the preparation of Example 6.

[0064] 2. Tested variety: conventional early rice "Zhong 86-44"

[0065] 3. Experiment design: The experiment consists of three treatments, namely:

[0066] Treatment ① Habitual fertilization (CK);

[0067] Treatment ② customary fertilization + spraying the same amount of clear water (CK + clear water);

[0068] Treatment ③ customary fertilization+spraying (CK+Example 6);

[0069] The test was repeated three times, the cells were randomly arranged, and the cell area was 2.5m×8m=20m 2

[0070] 4. Description of experimental design: customary fertilization, which is the local average fertilization level, that is, 25 kg / mu of ammonium bicarbonate, 20 kg / mu of calcium superphosphate, ...

[0098] The effect of applying multi-element and high-concentration liquid fertilizer at heading stage of wheat on yield

[0099] A comparative test of the spraying effects of different multi-element high-concentration liquid fertilizers was arranged in the wheat experimental field of students of the Department of Agriculture. The results show that the multi-element high-concentration liquid fertilizer of the present invention can significantly increase the 1000-grain weight of wheat, which is 11.37% higher than that of the clear water control. , and also significantly improved the yield per unit of wheat, which was 20.52% higher than that of the clear water control, but the effect on the number of grains per panicle and the number of grains per mu was not significant. Green Fenwei has no obvious effect on various characters in this test.

[0123] First, the basic situation of the test

[0124] The experiment was carried out in Xiahuo Village, Jinshan Township, Tongcheng County. The soil types were gravel white mud fields developed by river alluvium, fluvo-aquic vegetable garden soil, and the soil fertility was medium. Multi-element high-concentration liquid fertilizer (Example 8) was used to irrigate the roots, and 5000ml of multi-element high-concentration liquid fertilizer was poured into 500kg of water in turn per mu each time to make a 1:100 times liquid, and irrigated after mixing. Rape is set up in three groups: (1) clear water group: irrigate clear water once every 10 days; (2) experimental group: start to irrigate multi-element high-concentration liquid fertilizer (embodiment 8) at the root at the initial flowering stage, every 10 days Re-irrigation was performed once and repeated three times. Other times were the same as in the clear water group, and water was irrigated once every 10 days: the dosage an...

Abstract

The invention relates to a preparation method of a multi-element high-concentration liquid fertilizer with the stable performance, aiming at solving the problems of fewer kinds, low element content and poor adhesive power of a traditional multi-element high-concentration liquid fertilizer. In the technical scheme, the multi-element high-concentration liquid fertilizer comprises 100-200 parts of urea, 50-200 parts of phosphoric acid, 50-500 parts of at least one of monopotassium phosphate, potassium pyrophosphate, potassium hydroxide or potassium nitrate, 10-100 parts of borax, 1-50 parts of ammonium molybdate, 1-50 parts of magnesium sulfate, 1-50 parts of EDTA (Ethylene Diamine Tetraacetic Acid) manganese and 10-100 parts of zinc sulfate, wherein the ratio of the weight of water to the total weight of the raw materials is 3:4. The multi-element high-concentration liquid fertilizer is prepared from the raw materials through a chemical reaction and has the advantages of great specific weight, favorable adhesive power and stable performance.
