Problems solved by technology

[0004] In my country, the soil in the main sugarcane planting areas is brick red soil, red soil, etc. However, most of the special fertilizers for sugarcane on the market contain three components of N, P, and K plus fungicides, and a few special fertilizers for sugarcane contain only N, P In addition to the three macroelements, K and K, it also contains a small amount of medium and trace elements, such as Ca, Mg, S, Cl, B, Zn, Cu, Mo and other elements and organic matter, in order to meet the nutrients needed in the growth process of sugarcane, but It did not consider the specific needs of sugarcane for different medium and trace elements in different soils, resulting in low yields of sugarcane per unit area and waste of trace elements in fertilizers during fertilization, and even blindly pursuing yield increases and excessive application, resulting in excessive soil fertility decline. On the contrary, it affects the crop quality

Embodiment 1

[0034] The compound fertilizer preparation method that improves sugarcane yield is as follows:

[0035] (1) Pour urea, ammonia water, monoammonium phosphate, calcium silicate, lime, magnesium sulfate, copper sulfate, boric acid, sodium molybdate, zinc sulfate, amino acid and peat into the reaction kettle with heating jacket and stirring device in proportion In the process, the temperature was controlled at 40° C. and stirred for 70 minutes to obtain the primary mixture, wherein the stirring rate was controlled at 300 rad / min.

[0036] (2) After testing, each active ingredient is calculated according to the mass percentage of pure nutrients, including: 35% of macroelements, 8% of medium elements, 0.1% of trace elements and 15% of organic auxiliary materials; among them, Si element and Ca element The mass sum is 5%.

[0037] (3) Pour out the initial mixture from the reaction kettle, put it into a granulator for granulation, and dry it at a temperature of 90° C., cool it, pass t...

Abstract

The invention provides a composite fertilizer for improving the output of sugarcane, and relates to the agriculture field. The effective components of the composite fertilizer comprise, by mass, 28-42% of macro-elements, 5-14% of medium elements, 0.1-3% of trace elements and 8-17% of organic auxiliary materials. The composite fertilizer for improving the output of sugarcane improves various nutrient substances needed in the sugarcane growth process, improves the quality of sugarcane, improves the output and the sugar content of the sugarcane, improves the properties of the soil and has an increased utilization rate. The invention also provides a preparation method of the composite fertilizer for improving the output of sugarcane. The preparation method is simple and saves the preparation cost.

Description

technical field [0001] The invention relates to an agricultural fertilizer, and in particular to a compound fertilizer for improving sugarcane yield and a preparation method thereof. Background technique [0002] Sugarcane is rich in sugar and water, and also contains various vitamins, fats, proteins, organic acids, calcium, iron and other substances that are very beneficial to human metabolism. It is mainly used for sugar production, and can also be used to refine ethanol as an energy substitute. [0003] Sugarcane is also the main raw material for sugar production in China. At present, my country accounts for more than 80% of the world's total sugar production. Sugarcane is not only an important raw material for sugar production, but also one of the important raw materials for light industry, chemical industry and energy. Therefore, the development of sugarcane production plays an important role in improving people's living standards and promoting the development of agricu...
