Liquid fertilizer with sterilization and leaf protection functions and preparation method of liquid fertilizer

Abstract

The invention discloses a liquid fertilizer with sterilization and leaf protection functions. The liquid fertilizer is prepared from the following raw materials in parts by weight: 2-3 parts of manganese sulfate, 6-8 parts of potassium nitrate, 4-5 parts of quartzite powder, 7-9 parts of tea dregs, 2-4 parts of salicylic acid, 4-6 parts of monopotassium phosphate, 4-5 parts of reed vinegar liquid, 3-5 parts of ferric chloride, 4-7 parts of bract of carpesium macrocephalum, 2-3 parts of manganese sulfate monohydrate, 0.1-0.2 part of 2,3-D-butyl ester, 0.1-0.3 parts of N-dimethylamino succinamide, 5-6 parts of strobile of platycladus orientalis, 3-5 parts of iron-containing waste residue and 8-12 parts of a compounding agent. The liquid fertilizer contains various bioactive components and is rich in medium-trace elements such as iron and calcium required by crops; by spraying ground slurry, with a sterilization effect, of the bract of carpesium macrocephalum and the strobile of platycladus orientalis, diseases and pests on the leaf surfaces of the crops can be effectively reduced; the liquid fertilizer is wide in application range.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a liquid fertilizer for sterilizing and protecting leaves and a preparation method thereof. Background technique [0002] Due to its instant and uniform advantages, liquid fertilizer is the first choice for fertilization of irrigation equipment. Due to its ready-to-use, it does not need to be stirred and dissolved, so it is very suitable for automatic fertilization. However, the research and development and production of liquid fertilizers in my country are still in their infancy, and most liquid fertilizers have problems such as low nutrient content, layered agglomeration and precipitation. In order to solve the above problems, the inventors selected various raw materials, and obtained a uniform and impurity-free liquid functional fertilizer through multi-step stirring and filtering production processes, which has high nutrient content and contains a variety of beneficial ba...
