Organic liquid fertilizer for mangoes and preparation method thereof

Abstract

The invention discloses an organic liquid fertilizer for mangoes and a preparation method of the organic liquid fertilizer. The fertilizer is prepared from the following raw materials in parts by weight: 50-70 parts of polypeptide amino acid liquid, 5-10 parts of urea, 20-40 parts of potassium lactate, 5-10 parts of dipotassium hydrogen phosphate and 5-10 parts of chelate of polypeptide amino acidliquid and a trace element composition. The organic liquid fertilizer for mangoes is comprehensive in large, medium and micro elements, and has the advantages of high nutrient content, low consumption, easiness in absorption by plants and high fertilizer utilization rate through reasonable matching of organic and inorganic nutritional ingredients; the fertilizer has the advantages of full water solubility, convenient and safe application, reduction of labor cost, applicability to long-term application and capability of supplementing a part of water-soluble organic matters, promoting the ecological balance of soil and achieving soil improvement and land maintenance effects, is suitable for hilly and mountainous region with harsh fertilization conditions, effectively reduces the labor and fertilizer cost of growers, obviously improves the yield and quality of mangoes, and increases planting benefits.

Description

Technical field[0001]The invention relates to the technical field of liquid fertilizers, in particular to an organic liquid fertilizer for mangoes and a preparation method thereof.Background technique[0002]Mango is the main planted fruit in the southern tropics. It is mainly grown in Hainan, Guangxi, Yunnan, and Guangdong. It is generally grown in hilly and mountainous areas. The planting environment is difficult and the soil organic matter is low. Farmers generally use compound fertilizers and other chemical fertilizers as fertilizer Organic fertilizer is mainly fermented with poultry manure and straw. The total nutrient is about 5% to 8%, and the water-soluble organic matter is low. Generally, it is only used as base fertilizer. The amount is large and the labor cost is high. The growers use organic fertilizer. The enthusiasm is not high. Mango is a perennial woody plant, which requires a large amount of fertilizer, and the fruit hanging is greatly affected by the weather. The gro...

Problems solved by technology

[0002] Mango is the main fruit grown in the southern tropics. It is mainly grown in Hainan, Guangxi, Yunnan, and Guangdong. It is generally planted in hilly and mountainous areas. The planting environment is relatively difficult and the organic matter in the soil is low. Farmers generally use chemical fertilizers such as compound fertilizers for planting fruit. , organic fertilizers are mainly fermented from poultry and livestock manure, straw, etc., with a total nutrient content of about 5% to 8%, low water-soluble organic matter, and generally only used as base fertilizers, which require large amounts and high labor costs. Farmers use organic fertilizers The enthusiasm is not high. Mango is a perennial woody plant, which requires a large amount of fertilizer, and the fruit setting is greatly affected by the weather. The growers basically carry out fertilizer management according to the initial fruit setting. Usually, they only topdress once, and it is difficult to use water on mountainous land. It is difficult to apply ordinary organic fertilizers when making fertilizers, and chemical fertilizers are commonly sprayed. The cost of fertilizers is high. Long-term use of chemical fertilizers and organic matter cannot be replenished in time, which can easily cause nutritional imbalances in mangoes, low utilization rates of chemical fertilizers, and obvious deficiencies, resulting in soil compaction and soil micro-ecological imbalance. , the plant growth is not strong, there are many diseases, resulting in high cost of fertilizer and medicine for planting mango, low commodity value, poor planting efficiency, which seriously affects the enthusiasm of growers
