A new type of liquid fertilizer special for capsicum that can be used for integrated prevention and control of diseases and insect pests and its preparation method

Abstract

The invention provides a novel special liquid fertilizer for integrated pest control for chili. The liquid fertilizer comprises 10-15 parts of urea-ammonium nitrate solution, 5-10 parts of ammonium polyphosphate solution, 5-10 parts of potash fertilizer, 0.1-0.5 part of trace elements, 20-40 parts of water, 1-5 parts of homemade plant-derived pesticide extract, 1-2 parts of soil conditioner, 2-5 parts of natural active organic material and 1-2 parts of natural surfactant, wherein the homemade plant-derived pesticide extract is obtained by mixing peach kernel, gardenia, herba houttuyniae and roxburgh rose according to a proportion and extracting the mixture with water. A preparation method of the liquid fertilizer comprises the steps of adding the prepared urea-ammonium nitrate solution and ammonium polyphosphate solution into a mixing tank according to the formula, adding other metered formula materials into the mixing tank, mixing, dissolving, and filtering, thus obtaining the liquid fertilizer. The prepared fertilizer has a good using effect, and is an environment-friendly special liquid fertilizer for chili.

Description

technical field [0001] The invention belongs to the field of fertilizers, and in particular relates to a novel special liquid fertilizer for capsicum which can be used for comprehensive prevention and control of diseases and insect pests and a preparation method thereof. Background technique [0002] Capsicum is a vegetable that is often seen on the table of our family. It belongs to Solanaceae and Capsicum. It is an annual or limited perennial herb. Stems subglabrous or slightly pilose, branches slightly zigzag bent. Pepper growth requires sufficient nitrogen, phosphorus, and potassium. Phosphorus plays an important role in the formation and development of flowers, and potassium is an essential element for fruit expansion. In production, nitrogen, phosphorus and potassium must cooperate with each other to improve yield and quality. At present, conventional fertilizers are widely used in pepper fields in my country, and the application of trace elements is not paid attenti...

Problems solved by technology

[0003] Most of the existing capsicum fertilizers are based on solid fertilizers. Patent CN200910255602.0 reports an organic-inorganic compound fertilizer and its preparation method. It is a special capsicum for preventing and controlling soil-borne diseases produced by using decomposed organic matter, inorganic fertilizers and pesticides as the main raw materials. Organic-inorganic compound fertilizer, the decomposed organic matter is obtained by accumulating and fermenting 1-2 parts of edible fungus residue, cake, and microbial fermentation agent EM compound agent, and airing until the moisture content is 30-35wt%. The main problem is that the organic matter content is insufficient , the extensive use of inorganic fertilizers reduces the content of organic matter in the soil, and the soil is easy to harden, and due to the comprehensive influence of fertilizer properties and soil environmental conditions, low fertilizer utilization is a common problem in the application of inorganic fertilizers. Excessive application of inorganic fertilizers leads to Soil compaction and reduced soil permeability

Existing organic liquid fertilizers have disadvantages such as unbalanced trace elements and poor application effect
