Special mango liquid compound fertilizer and preparation method thereof

Abstract

The invention discloses special mango liquid compound fertilizer. The fertilizer comprises the following raw materials in parts by weight: 40-80 parts of fermentation liquor, 1-15 parts of potassium nitrate, 5-20 parts of urea, 2-15 parts of monobasic potassium phosphate, 0.5-5 parts of magnesium sulfate, 0.5-5 parts of calcium sulfate, 0.5-10 parts of trace elements and 1-5 parts of rubber liquid. The preparation method of the liquid compound fertilizer comprises steps as follows: after the fermentation liquor is heated, magnesium sulfate and calcium sulfate are added sequentially for continuous heating and stirring, the rubber liquid is added for uniform mixing after sufficient dissolution, potassium nitrate, urea, potassium dihydrogen phosphate and the trace elements are added sequentially, heating and stirring are maintained until the added previous raw materials are completely dissolved, and then the next raw material is added. The invention provides the mango liquid compound fertilizer which is easily absorbed by mango trees and can fully and reasonably use molasses and a preparation method of the mango liquid compound fertilizer. The compound fertilizer is rich in nitrogen,phosphorus, potassium and organic matter, can fully promote growth of the mango trees, enables the mangoes to be rich in various medium and trace elements, and increases sweetness and texture of the mangoes.

Description

technical field [0001] The invention relates to the technical field of fertilizer production, in particular to a special liquid compound fertilizer for mango and a preparation method thereof. Background technique [0002] How to increase the yield of mango is one of the key factors to improve the economic benefits of mango, and fertilization is one of the essential measures to improve the yield of mango. The red soil area accounts for a large proportion of the soil in Guangxi. The nitrogen, phosphorus, and potassium nutrients in the soil are relatively deficient, and the calcium and magnesium contents are also insufficient. The trace elements, especially copper, zinc, and boron, are low in content, and the site conditions vary widely. Especially when the geological conditions are not very uniform, the application of solid fertilizers is prone to unevenness, which cannot fully meet the needs of mango growth, and may easily lead to the occurrence of physiological diseases, res...

The red soil area accounts for a large proportion of the soil in Guangxi. The nitrogen, phosphorus, and potassium nutrients in the soil are relatively deficient, and the calcium and magnesium contents are also insufficient. The trace elements, especially copper, zinc, and boron, are low in content, and the site conditions vary widely. Especially when the geological conditions are not very uniform, the application of solid fertilizers is prone to unevenness, which cannot fully meet the needs of mango growth, and may easily lead to the occurrence of physiological diseases, resulting in a decrease in yield. Fertilizer will dissolve faster, which reduces the effect of fertilizer application on the one hand, causes waste of fertilizer, and pollutes the surrounding water body

[0003] Guangxi is the most suitable place in the world to grow sugar cane. Planting sugar cane to make sugar has become a mature industrial chain. In the process of sugar making, a large amount of by-product molasses will be produced. Many sugar making enterprises directly discharge molasses as waste, and some Enterprises dope molasses into solid compound fertilizer. However, due to the high molecular weight of molasses, it is difficult for plants to absorb it directly into the soil, and it is easy to cause the loss of components. As the rainwater flows into the surrounding water body, it will cause eutrophication. Therefore, it is necessary to find a A production method that can fully integrate molasses and fertilizer
