Novel special liquid fertilizer for rice capable of comprehensively controlling plant diseases and insect pests, and preparation method thereof

Abstract

The invention provides a novel special liquid fertilizer for rice capable of comprehensively controlling plant diseases and insect pests, and a preparation method thereof. The novel special liquid fertilizer is prepared from the following components: 5 to 15 parts of urea-ammonium nitrate solution, 5 to 15 parts of ammonium polyphosphate solution, 5 to 10 parts of potash fertilizer, 0.1 to 2 parts of microelement, 20 to 50 parts of water, 1 to 10 parts of homemade plant pesticide extracting solution, 1 to 2 parts of soil conditioner, 1 to 5 parts of natural activity organic materials, and 1 to 5 parts of natural surfactant, wherein the homemade plant pesticide extracting solution is prepared from mixing trifolium pratense, folium artemisiae argyi, herba houttuyniae, semen persicae and black false hellebore in proportion, and extracting with water. The preparation method comprises the steps of adding the prepared urea-ammonium nitrate solution and the ammonium polyphosphate solution in proportion according to a formula into a mixing tank; then adding the other metered materials into the mixing tank; stirring, dissolving and filtering to prepare the liquid fertilizer. The liquid fertilizer provided by the invention is convenient to use and good in effect, and is a special multi-functional environment-friendly liquid fertilizer for the rice.

Description

technical field [0001] The invention belongs to the field of fertilizers, and in particular relates to a novel special liquid fertilizer for rice that can be used for comprehensive prevention and control of diseases and insect pests and a preparation method thereof. Background technique [0002] Rice is a kind of herbaceous Oryza genus, and it is also the most important and oldest kind of grain in Oryza genus. It is also called Asian cultivated rice, and it can be said to be rice in simple terms. It is an annual, gramineous plant, monocotyledonous, sexually warm and humid, about 1 meter high when mature, with slender leaves, about 50 to 100 cm long and 2 to 2.5 cm wide. The flowers of rice are very small. When blooming, the main flowering branches will be arched, and small flowers will bloom between 30 and 50 mm down from the branches. Most of them are self-pollinating and set seeds, which are called rice spikes. Typical rice grains are 5 to 12 mm long and 2 to 3 mm thick. ...

AI Technical Summary

Problems solved by technology

The raw materials of the medicinal fertilizer include: microbial flora, humic acid, nitrogen fertilizer, phosphate fertilizer, potassium fertilizer, borax, pesticides, water-soluble isolating agent, plant growth regulator, water, etc., mainly due to the lack of trace elements, resulting in insufficient rice production. There are also direct addition of pesticides and plant growth regulators. These commercial preparations contain a large amount of organic solvents, pollute the environment, and have insufficient stability in water and the risk of stratification
