Zinc-enriched nutrient, its preparation method and cultivation method of zinc-enriched garlic seedlings

Abstract

The invention discloses a zinc-rich nutritional agent and a preparation method thereof, as well as a method for cultivating zinc-rich garlic sprouts. The zinc-rich nutritional agent comprises the following components in parts by mass: 2-20 parts of zinc source, 3-30 parts of organic fertilizer, 1-10 parts of humic acid and 0.15-0.75 part of selenium ore; the zinc-rich nutritional agent is prepared by crushing selenium ore and zinc powder into a micron order, uniformly mixing the selenium ore and zinc powder according to a mass ratio of (0.15-0.75):(2-20) for later use, weighing a commercial organic fertilizer and humic acid according to a mass ratio of (3-30):(1-10), and uniformly mixing for later use; uniformly mixing an obtained product, pelleting on a disc pelleting machine, and spraying a proper amount of adhesives when the particle diameter is 2-3mm during disc pelleting. The method for cultivating garlic sprouts comprises the following steps: soaking seeds by using a 0-100 ppm zinc-containing solution, and spraying the zinc-rich nutritional agent in the growth process of garlic seedlings so as to obtain zinc-rich garlic seedlings.

Description

technical field [0001] The invention relates to the technical field of crop fertilization, in particular to a method for cultivating zinc-rich garlic seedlings. Background technique [0002] Garlic seedlings, also known as gourd, gourd garlic, meat dish, single garlic, single head garlic, are Liliaceae allium plants, bulbs are called garlic heads, stems and leaves are called garlic moss, and flower stems are called garlic sprouts. It is a traditional plant that is widely eaten as a condiment. , has significant antibacterial, anti-inflammatory and anti-tumor effects, and is known as "natural broad-spectrum antibiotic". The bactericidal ability can reach 10% of penicillin and it is not easy to produce drug resistance. In addition to a considerable amount of protein and carbohydrates, garlic sprouts are also rich in calcium, phosphorus, iron, zinc and vitamin C, as well as thiamine, riboflavin, niacin, allicin, citral, selenium and germanium, etc. trace elements. Garlic sprou...

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, but whether it is rice or wheat, the zinc content after enrichment is not particularly ideal, and the planting of different varieties will be restricted by geographical, climatic and other conditions, so it cannot be widely promoted
