Problems solved by technology

The reasons for molybdenum deficiency in southern and northern feed are different. The available molybdenum content in the northern soil is lower than the critical concentration of molybdenum deficiency (0.15mg / kg); Under these conditions, the uptake and utilization of molybdenum by forage plants is almost zero

Abstract

A Mo-complementing forage additive containing the controlled slow releasing Mo is an active Mo contained hydrotalcite prepared from molybdate and hydrotalcite through calcining hydrotalcite, adsorption, ionic exchange reaction, filtering, drying and pulverizing.

Description

technical field [0001] The invention relates to a molybdenum replenishing agent for controlled and slow-release molybdenum, a preparation method and application. Background technique [0002] Molybdenum (Mo) is one of the trace elements necessary for the growth of animals and plants, and widely exists in soil, water, air, plant and animal tissues. Molybdenum was first recognized by zoologists as a toxic element. Molybdenum poisoning can cause severe diarrhea and hair discoloration in grazing sheep, which is called "Teart" disease. Therefore, people have always regarded molybdenum as a toxic substance and have long been committed to the research on the prevention and treatment of molybdenum poisoning in animals. [0003] Molybdenum is an indispensable trace element in animals and plays an important role in the growth, development and genetics of animals. Molybdenum is mainly dependent on molybdenum enzymes (xanthine oxidase, aldehyde oxidase, sulfite oxidase) to participate...
