Problems solved by technology

[0002] The climate characteristics of northern Yunnan are mainly divided into dry season and rainy season. That is to say, most of the agricultural production in northern Yunnan is plagued by water shortage. The rapid evaporation of water in the soil intensifies the pressure on agricultural production, especially in Zhaotong. , the planting of apple trees is the main agricultural pillar industry in Zhaotong area, but Zhaotong area is not a livestock area, it is difficult to obtain a large amount of continuous metabolite fertilizer for cattle and sheep in Zhaotong area, and the application effect of metabolites of other animals is not ideal and composting It is difficult. In order to obtain good growth conditions of apple trees, existing planters use a large amount of various inorganic fertilizers. These fertilizers containing nitrogen, phosphorus and potassium will indeed provide a large amount of growth elements needed by apple trees in the short term, but The price of fertilizing for a long time is that the fertile plateau soil becomes more barren, and a large number of hardening phenomena appear, which seriously affects the long-term sustainable development of apple planting areas. Similar problems in Zhaotong area still exist in other parts of the country
[0003] It is undoubtedly the best choice to use a chemical fertilizer that can provide sufficient nutritional requirements and can also continuously improve the soil fertility in these areas. The existing technology mostly uses chemical fertilizers with high content of humic acid combined with calcium and magnesium to achieve this purpose , but in the prior art, fertilizers containing calcium-magnesium-bound humic acid generally have a higher price, because calcium-magnesium-bound humic acid needs to be obtained by processing lignite, and many enterprises directly use calcium-magnesium-bound humic acid after lignite purification It can be processed for other purposes or even discarded as waste. Using the existing technology to directly compost and ferment lignite can obtain a certain amount of humic acid combined with calcium and magnesium, but the content is extremely low and the composting time is very long

Abstract

The invention discloses a preparation method of a high-nutrient organic / inorganic compounded fertilizer which is used for a whole growth period of highland apple trees. The preparation method includes the steps of preparing lignite humic acid raw powder, crushing and mixing materials, performing granulation, drying granules and screening to obtain a finish product. The raw materials of the fertilizer are very easy to obtain. The preparation method achieves quick production and is free of a large number of production devices and expensive production devices. The lignite is directly processed to prepare the raw lignite powder being rich in calcium-magnesium-mixed humic acid. The raw lignite powder, after treatment, has significant effect on improvement of soil and increase of water retaining capacity of soil.
