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 early rice application multi-element high-concentration liquid fertilizer (embodiment 6) field fertilizer effect test

[0062] 1. Materials and methods

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

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

[0065] 3. Experimental design: There are three treatments in the experiment, namely:

[0066] Treatment ① customary fertilization (CK);

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

[0068] Process 3. get used to fertilizing+spraying (CK+embodiment 6);

[0069] The experiment was repeated three times, the plots were randomly arranged, and the plot area was 2.5m×8m=20m 2

[0070] 4. Explanation of the experimental design: customary fertilization, which is the local average fertilization level, that is, 25 kg / mu of ammonium bicarbonate, 20 kg / mu of superphosphate, 5 kg / mu of potassium chloride, an...

[0098] Effects of applying multi-element high-concentration liquid fertilizer on yield of A wheat at heading stage

[0099] The comparison test of different multi-element high-concentration liquid fertilizer spraying effects was arranged in the wheat experiment field of the students of the Department of Agronomy. The results showed that the multi-element high-concentration liquid fertilizer of the present invention can significantly increase the thousand-grain weight of wheat, which is 11.37% higher than that of the clean water control. , and also significantly increased the yield of wheat, which was 20.52% higher than that of the clear water control, but had no significant effect on the number of grains per panicle and the number of grains per mu. In this test, Green Fenway has no obvious effect on the traits.

[0123] 1. Basic conditions of the test

[0124] The experiment was carried out in Xiahuo Village, Jinshan Township, Tongcheng County. The soil type was gravel white mud field developed by river alluvial deposits, fluvo-aquic soil vegetable garden soil, and the soil fertility was medium. Adopt multi-element high-concentration liquid fertilizer (embodiment 8) to irrigate at the roots, and inject 5000ml of multi-element high-concentration liquid fertilizer into 500kg water successively per mu each time, be made into 1: 100 times of liquid, apply irrigation after mixing. Rapeseed has three groups: (1) clear water group: irrigate clear water once every 10 days; (2) experimental group: begin to irrigate and apply multi-element high-concentration liquid fertilizer (embodiment 8) at the root at the initial flowering stage, every 10 days Irrigate once again, repeat three times, the other time is the same as that of the water group, and irrigate with water once every 10 days: the dosage...

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.
