Special environmental-friendly organic controlled release fertilizer for grapes and preparation method thereof

Abstract

The invention relates to the field of fertilizers, and in particular relates to a special environmental-friendly organic controlled release fertilizer for grapes. The grape planting high-utilization-rate odorless organic fertilizer is prepared from the following raw materials in parts by weight: 100 to 128 parts of dry natural cow dung, 40 to 68 parts of charcoal, 30 to 55 parts of coated controlled release phosphate fertilizer, 6 to 13 parts of plant ash, 10 to 15 parts of kieselguhr, 4 to 5 parts of sodium alginate, 10 to 16 parts of humic acid liquid, 10 to 20 parts of chitosan, 5 to 11 parts of ammonium molybdate, 10 to 13 parts of attapulgite clay, 10 to 13 parts of fertilizer controlled release formulation, 3 to 13 parts of polyethylene glycol and 20 to 25 parts of surfactant. The special environmental-friendly organic controlled release fertilizer for grapes has the advantages of comprehensive and rich nutrients, low preparation cost, longer fertilizer persistence and rich organic matters, cannot cause soil hardening after long-term use, can increase organic matter content in the soil, and can achieve the effects of continuously increasing of production and income.

Description

technical field [0001] The invention relates to the field of grape fertilizers, in particular to a special environment-friendly organic slow-release fertilizer for grapes and a preparation method thereof.

[0003] The use of fertilizers in the grape planting process plays a key role in the yield and quality of grapes. However, there are many shortcomings in the grape fertilizers currently available on the market: First, they do not target the specific nutritional needs of grapes and soil nutritional characteristics, but simply Provide a large amount of nutrients such as nitrogen and phosphorus; second, chemical fertilizers are mainly used, supplemented by organic fertilizers, which easily produce chemical residues and pollute the environment; third, they cannot improve the soil, which will lead to poor soil in the long run and are not suitab
