Abstract

The invention discloses a plant immune type direct-spraying liquid compound fertilizer and a preparation method thereof, wherein the compound fertilizer comprises the following raw materials in parts by mass: 2 parts of water, 0.25 part of a chelating agent, 0.25 part of trace elements, 3 parts of an activated organic nutrient solution, 1.5 parts of a potassium fertilizer, 1.5 parts of a nitrogen fertilizer, 1 part of a phosphorous acid solution, and 0.5 part of a potassium hydroxide solution. According to the invention, large, medium and trace elements in organic and inorganic nutrients and a plant bactericidal immunizing agent are integrated in the liquid compound fertilizer, and direct sprinkling can be realized without digging holes, so that the labor efficiency is greatly improved, and the work is not tedious any more. The problems of difficulty in fertilization of solid fertilizer, single element, poor dissolution and absorption and the like are effectively solved or improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a plant-immune direct spray liquid compound fertilizer and a preparation method thereof. Background technique [0002] Fertilizer is an essential substance to promote plant growth and increase production, and it is also one of the important conditions for the development of agricultural production. At present, the common fertilizers on the market are high-concentration solid fertilizers with relatively single components, such as urea and nitrophosphate fertilizers. However, these solid fertilizers can only provide macronutrients such as nitrogen, phosphorus, and potassium, and almost do not contain medium and trace elements, so that the crops have low lodging resistance, resistance to diseases and insect pests, and solid fertilizers are difficult to dissolve. The absorption efficiency is low, and When fertilizing, it is often necessary to dig pits and bury fertilizers. Even ...
