Sugar alcohol zinc boron molybdenum manganese compound colloidal solid leaf microelement fertilizer and preparation method thereof

Abstract

The invention belongs to the field of agricultural production, and discloses a sugar alcohol zinc boron molybdenum manganese compound colloidal solid leaf microelement fertilizer and a preparation method thereof. The colloidal fertilizer is composed of solid salts of various microelements, a pH conditioning agent, a chelating agent, a potentiating agent, a surface active material, an antibacterialagent and an adhesion agent. Firstly, heating reaction is carried out on molybdenum salt and the chelating agent, then solid boron salt, the pH conditioning agent, zinc salt, manganese salt, the potentiating agent and the adhesion agent which are evenly stirred are added, the surface active material and germicide are added, heating is carried out to make the mixture mixed evenly, so that the mixture is changed into jelly from liquid to obtain a compound fertilizer with high concentration, stability and good effect. According to the sugar alcohol zinc boron molybdenum manganese compound colloidal solid leaf microelement fertilizer and the preparation method thereof, after the prepared compound fertilizer is sprayed on the leaf surface, a surface active agent makes the microelement fertilizer spread on the leaf surface evenly, the adhesion agent resists washing of rainwater and prolongs the fertilizer efficiency time, the contained microelements are essential ingredients of the plant growth, the leaf fertilizers are stored and transported easily, and are dissolved easily when being in use.

Description

technical field [0001] The invention relates to the field of agricultural production, in particular to a sugar alcohol zinc boron molybdenum manganese composite colloidal solid foliage micro-fertilizer and a preparation method thereof. Background technique [0002] Trace elements such as zinc, boron, manganese, and molybdenum are essential nutrients for crops. Although crops have little requirement for trace elements, they are equally important to the growth and development of crops as nitrogen, phosphorus, and potassium. When a certain trace element is deficient, the growth and development of crops will be significantly affected, the yield will be reduced, and the quality will be reduced. When zinc is deficient, plant growth is inhibited, especially internode growth is severely hindered, and intervein chlorosis or albinism symptoms are shown; boron exists in the form of acid radicals in plants and participates in many important physiological activities. Irreplaceable speci...

Problems solved by technology

[0003] At present, most of the micro-fertilizers for foliage in the market are liquid and solid. The packaging and transportation of liquid fertilizers are relatively difficult, and they are greatly affected by the environment, and precipitation and sedimentation may occur

It takes a long time to dissolve solid fertilizer
