Organic liquid fertilizer for tomatoes and preparation method thereof

Abstract

The invention discloses an organic liquid fertilizer for tomatoes and a preparation method thereof. The organic liquid fertilizer comprises the following components in parts by weight: 50-70 parts ofpolypeptide amino acid liquid, 1-10 parts of urea, 20-40 parts of potassium nitrate, 1-10 parts of diammonium phosphate and 1-10 parts of a chelate of polypeptide amino acid liquid and a trace elementcomposition. The organic liquid fertilizer for tomatoes has the advantages of comprehensive and reasonably proportioned large, medium and micro elements, organic-inorganic coordination, high nutrientcontent, low salt content, easiness in plant absorption, high fertilizer utilization rate, full water solubility, convenience and safety in application, reduction of fertilizer labor cost, suitability for long-term application and capability of supplementing a part of water-soluble organic matters, promoting soil ecological balance and exerting soil improvement and land maintenance effects; and the organic liquid fertilizer is particularly suitable for greenhouse planting, effectively reduces the labor and fertilizer costs of growers, obviously improves the yield and quality of tomatoes and increases planting benefits.

Description

technical field [0001] The invention relates to the technical field of liquid fertilizers, in particular to a tomato organic liquid fertilizer and a preparation method thereof. Background technique [0002] Tomatoes are generally planted in greenhouses or paddy fields and picked many times. Farmers generally use chemical fertilizers such as compound fertilizers or water-soluble macronutrient fertilizers when planting. Organic fertilizers are mainly fermented livestock manure and straw. The total nutrients At about 5%-8%, the water-soluble organic matter is low, and it is generally only used as base fertilizer. The amount of organic fertilizer used is large and the labor cost is high. The amount of organic fertilizer applied to the base fertilizer during planting is generally not enough to support the entire growth and development of tomatoes, and tomatoes bloom and bear fruit at the same time. It requires a large amount of fertilizer, farmers generally apply chemical fertili...

[0002] Tomatoes are generally planted in greenhouses or paddy fields and picked many times. Farmers generally use chemical fertilizers such as compound fertilizers or water-soluble macronutrient fertilizers when planting. Organic fertilizers are mainly fermented livestock manure and straw. The total nutrients At about 5%-8%, the water-soluble organic matter is low, and it is generally only used as base fertilizer. The amount of organic fertilizer used is large and the labor cost is high. The amount of organic fertilizer applied to the base fertilizer during planting is generally not enough to support the entire growth and development of tomatoes, and tomatoes bloom and bear fruit at the same time. It requires a large amount of fertilizer, farmers generally apply chemical fertilizers, and the cost of using fertilizers is high. Long-term application of chemical fertilizers and organic matter cannot be replenished in time, which will easily cause tomato nutritional imbalance, low utilization rate of chemical fertilizers, and obvious deficiencies, resulting in soil compaction and salinization of greenhouses. Severe, soil micro-ecological imbalance, unhealthy plant growth, many diseases, resulting in high cost of fertilizer and medicine for planting tomatoes, low commodity value, poor planting efficiency, seriously affecting the enthusiasm of growers
