Zinc-enriched nutrient, its preparation method and method for cultivating zinc-enriched vegetable

Abstract

The invention discloses a zinc-rich nutritional agent, a preparation method thereof and a method for cultivating zinc-rich sedum aizoon. The zinc-rich nutritional agent comprises the following materials in parts by weight: 4-40 parts of zinc source (by the mass of zinc), 3-30 parts of organic fertilizer, 0.1-0.6 part of borax and 0.05-0.3 part of molybdenum sulfide. The manufacturing method comprises the following steps of: crushing the molybdenum sulfide and the borax, mixing according to the mass ratio being (0.05-0.3):(0.1-0.6), and crushing into powder with the particle diameter being less than 50mum, wherein the nano-level powder accounts for 3-25%; crushing zinc salt into powder, adding commercial organic fertilizers according to the mass ratio being (4-40):(3-30), and mixing uniformly for spare use; mixing obtained products, granulating on a disc granulator with the granules being 2-3mm in diameter, and spraying a bonding agent when in granulation of the disc granulator. The method for cultivating the sedum aizoon comprises the steps of: treating soil, applying a proper amount of compound fertilizer, and cultivating the sedum aizoon according to the conventional cottage method; and the applied amount of zinc-rich nutritional agent in the growth process of sedum aizoon is 4-40kg / mu and the zinc-rich sedum aizoon is obtained.

Problems solved by technology

Yet the zinc content after wheat and rice zinc fortification is also not very ideal, the rice zinc content of cultivation as described in Chinese patent CN101278715B is at most only 50mg / kg; The zinc content can reach 135mg / kg, ranking first in the world's existing cereal crops. However, whether it is rice or wheat, the planting of its varieties is restricted by geographical, climatic and other conditions, and it cannot be popularized on a large scale. It is still far from practical application. long time
