Problems solved by technology

At present, zinc-enriched plants are often enriched by applying zinc fertilizers to the soil. Generally, inorganic zinc is applied, and the final absorption efficiency is low. The enrichment of zinc in alfalfa is small, and when the amount of inorganic zinc used is large, it will cause soil pollution.

Embodiment 1

[0018] 1. a planting method of zinc-rich alfalfa, comprising the following steps:

[0019] Cultivate alfalfa according to the conventional method. When the alfalfa grows for one year, spray EDTA disodium zinc solution with a concentration of 50-200 mg / kg into the soil, and the spraying amount is 200-500 mg / mu, every morning from 8:00 to Spray at 10:00, and do not spray on rainy days. During the spraying period, the cultivation and management measures of alfalfa are the same as usual. Spray for 30 days, and then harvest to obtain zinc-rich alfalfa.

[0020] 2. A kind of zinc-rich alfalfa feed additive, is made up of the raw material of following weight portion:

[0021] 90-95 parts of zinc-rich alfalfa leaves, 60-65 parts of zinc-rich alfalfa roots, and 70-80 parts of zinc-rich alfalfa stems, wherein the zinc-rich alfalfa leaves, zinc-rich alfalfa roots, and zinc-rich alfalfa The stems are all obtained from the zinc-rich alfalfa.

[0022] 3. The preparation method of the zinc...

Abstract

The invention discloses a method for planting zinc-rich alfalfa, which comprises the following steps: cultivating alfalfa according to a conventional method, and spraying EDTA disodium zinc solution into the soil when the alfalfa grows for one year, at 8:00-10 every morning: 00 spraying, not spraying in rainy days, the cultivation and management measures of alfalfa during the spraying period are the same as usual, spraying for 30 days, and then harvesting. At the same time, the invention also discloses the zinc-rich alfalfa feed additive and its preparation method, as well as its application in feeding dairy cows. The planting method of zinc-rich alfalfa provided by the present invention has a high enrichment amount of organic zinc EDTA disodium zinc in alfalfa, and the feed additive prepared by finally distributing and combining leaves, roots and stems of alfalfa obtained by planting, Can increase the zinc content in milk.

Description

technical field [0001] The invention belongs to the technical field of alfalfa, and in particular relates to a method for planting zinc-rich alfalfa, a feed additive for zinc-rich alfalfa, a preparation method and application thereof. Background technique [0002] Zinc is a commonly used non-ferrous metal, silvery white with a slight bluish tint, it is the fourth most common metal after iron, aluminum and copper. Zinc is one of the essential trace elements for organisms, and it is also an essential nutrient element for plant growth and development. Zinc promotes crop growth and development, improves seed maturity rate, and promotes callus formation, pollination and fertilization, and increases thousand-grain weight. Significantly. It can enter the food chain through enrichment in plants and pass into the human body and animals through the food chain. [0003] Zn is widely distributed in nature, and Zn in soil mainly comes from parent materials. Therefore, the regional dis...
