Fertilizer for improving soil of citrus orchard and preparation method thereof

Abstract

The invention belongs to the technical field of fertilizer processing, in particular to a fertilizer for improving soil of a citrus orchard and a preparation method thereof. The fertilizer for improving the soil of the citrus orchard is prepared from the following raw materials in parts by weight: 500 to 600 parts of livestock manure, 150 to 200 parts of cassava residue, 1 to 1.5 parts of EM (effective microorganism) strain, 10 to 15 parts of brown sugar, 8 to 10 parts of ternary composite fertilizer, 20 to 50 parts of silica gel powder, and 50 to 70 parts of plant extracting solution. The fertilizer for improving the soil of the citrus orchard has the advantages that the production technology is simple, the sources of the raw materials are wide, the raw materials can be selected locally,the cost is low, and the safety of people, livestock and crops in use is guaranteed; when the fertilizer is applied as the base fertilizer, the pH (potential of hydrogen) value of the soil can be reduced, the alkalinity of the soil is reduced, the decomposing is easy, the residue of toxin is avoided, and the pollution to environment is reduced.

Description

【Technical field】 [0001] The invention relates to the technical field of fertilizer processing, in particular to a fertilizer for improving the soil of citrus orchards and a preparation method thereof. 【Background technique】 [0002] Soil is the foundation of citrus growth, and the nutrients and water needed by citrus are extracted from the soil. Therefore, it is required to have a deep soil layer, loose texture, suitable pH, low groundwater level, good drainage, and soil rich in organic matter in order to make citrus plants grow well. Citrus has a wide range of adaptability to soil pH, but the most suitable pH value is 5.5-6.5. [0003] The following problems generally exist in the soil of citrus orchards in Debao County: [0004] 1. The types of citrus cultivation gardens in Debao County are mainly hilly and dry land, and the soil type is mainly purple soil. The soil pH is high, the soil layer is shallow, the ability to retain water and fertilizer is poor, and the soil i...

AI Technical Summary

Problems solved by technology

[0004] 1. The types of citrus cultivation gardens in Debao County are mainly hills and mountains and dry land. The soil type is mainly purple soil. The soil pH is high, the soil layer is shallow, the ability to retain water and fertilizer is poor, and the soil is prone to drought and salinization

[0005] 2. Low fertilizer use efficiency and cause agricultural non-point source pollution

Unreasonable fertilization schemes also lead to serious loss of nitrogen and potassium in the form of runoff and ammonia volatilization, and phosphorus is fixed in the soil and becomes invalid

[0006] The above soil quality problems have seriously affected the sustainable use of citrus orchard soil, and brought hidden dangers to the cultivation of citrus
