Special fertilizer for ecological organic watermelons and production method thereof

Abstract

The invention relates to the technical field of environment-friendly organic fertilizers, and discloses a special fertilizer for ecological organic watermelons and a production method thereof.The production method comprises the steps that biochar obtained after carbonization treatment of crop straw is mixed with livestock and poultry manure, biogas residues, slaked lime and a decomposition agent according to a certain proportion, decomposition fermentation is conducted, and a fermented fertilizer is obtained; and the fermented fertilizer is fully and uniformly mixed with a watermelon auxiliary fertilizer, a conventional fertilizer and a beneficial bacterial agent according to a ratio to obtain a compound fertilizer, the compound fertilizer is mixed with a forming auxiliary agent and wood vinegar according to a ratio, deodorizing and granulating are performed to obtain the special fertilizer for the ecological organic watermelons. Moreover, the air permeability, water retention and fertilizer retention capabilities of the soil are effectively enhanced, and the quality of watermelons is improved.

Description

technical field [0001] The invention belongs to the technical field of environment-friendly organic fertilizers, and in particular relates to a special fertilizer for ecological organic watermelons and a production method thereof. Background technique [0002] Watermelon is not only sweet and delicious, refreshing and juicy, but also contains a lot of glucose, lycopene, fructose, amino acids and rich vitamin C. It has high edible value and is a healthy, nutritious and delicious summer fruit. At present, my country's watermelon planting area is huge, and its output ranks first in the world, accounting for more than 45% of the world's total output. The demand for watermelon fertilizers is also huge, but there are few types of watermelon fertilizers on the market. Most watermelon growers choose nitrogen, phosphorus, and potassium fertilizers. , but conventional chemical fertilizers are easy to lose from the soil, and the utilization rate of fertilizers is low, and excessive use ...

Problems solved by technology

At present, my country's watermelon planting area is huge, and its output ranks first in the world, accounting for more than 45% of the world's total output. The demand for watermelon fertilizers is also huge, but there are few types of watermelon fertilizers on the market. Most watermelon growers choose nitrogen, phosphorus, and potassium fertilizers. , but conventional chemical fertilizers are easy to lose from the soil, and the fertilizer utilization rate is low, and excessive use of chemical fertilizers can easily cause soil compaction, which is not conducive to the growth of watermelon plant roots and increases the planting cost of fruit farmers

In addition, the fertilizer lost from the soil will also cause eutrophication of the water body, pollute the water body, and endanger the ecological environment.

[0003] The unreasonable and non-compliant treatment of agricultural waste not only wastes agricultural resources, but also causes serious pollution to the ecological environment

For example, the incineration of agricultural waste stalks produces a large amount of smoke and dust that seriously affects air quality; rural farmers’ random treatment of livestock and poultry manure not only pollutes water and soil, but also produces stench that affects the normal life of residents; anaerobic The remaining biogas slurry and residue after fermentation to produce biogas is acidic or weakly acidic. Long-term application of acidic fertilizers will cause soil acidification and compaction, resulting in secondary pollution
