Selenium yeast leaf fertilizer as well as preparation method and application thereof

Abstract

The application discloses selenium yeast leaf fertilizer as well as a preparation method and application thereof. A suspending agent for preparing the yeast leaf fertilizer is prepared from the following raw materials in parts by weight: 10 to 60 parts of soluble selenium-rich yeast, 1 to 30 parts of a moistening agent, 1 to 30 parts of a dispersing agent, 1 to 20 parts of a synergist, 0.1 to 1 part of a defoaming agent, 1 to 10 parts of an anti-freezing agent, 0.1 to 3 parts of a thickening agent and the balance of water. Wettable powder for preparing the selenium yeast leaf fertilizer comprises the following raw materials in parts by weight: 10 to 60 parts of soluble selenium-rich yeast, 1 to 30 parts of a moistening agent, 1 to 30 parts of a dispersing agent and the balance of anhydroussodium sulphate. The selenium yeast leaf fertilizer has low toxicity and low environment pollution. The selenium yeast leaf fertilizer is matched with the synergist, so that the leaf fertilizer has high long-acting fertilizer efficiency, and the adhesive power of leaf fertilizer liquid drops is facilitated through the synergist; heavy metals in crops can be degraded; undesirable influences such as antagonism of hard water ions on effective components can be lowered, and the development of the performance of the fertilizer is facilitated; the disease resistance of the crops is improved.

Description

technical field [0001] The invention relates to the technical field of crop fertilizers, in particular to a yeast selenium foliage fertilizer, a production method and application. Background technique [0002] Selenium is an essential element of glutathione peroxidase (GSH-P) in humans and animals, and every 1 mol of pure enzyme contains about 4 mol of selenium. GSH-Px is the first recognized selenium-containing enzyme in organisms. GSH-P widely exists in the liver, kidney, heart, lung, etc. of living organisms. Selenocysteine ​​provides the necessary gene for the enzyme's active center. GSH-P uses glutathione to make toxic peroxide Reduce to harmless hydroxyl compounds, decompose peroxides, remove active free radicals, protect cell membrane structure and function, and repair molecular damage. Selenium has many benefits to the human body. It can improve the body's immunity, scavenge free radicals, reduce the incidence of cancer, protect the liver, prevent diabetes and deto...

AI Technical Summary

Problems solved by technology

However, the existing foliar fertilizers have a low penetration rate of nutrients absorbed by the leaves due to the cuticle of the leaves

And it is easy to be lost. During the spraying process, if it is not operated properly or encounters strong winds, it is easy to drop from the leaf surface and waste the liquid medicine; it is easy to leaching and lost in rain. Generally, it needs to be re-fertilized when it rains 4 hours after spraying; If it is too dry, the liquid medicine will dry quickly on the leaf surface and absorb it, thereby improving the fertilizer effect.
