Problems solved by technology

And sodium selenite has certain toxicity, and biological potency is also very low, and the residence time in the body is short, generally only 3-4 hours, and excessive addition is not conducive to food safety because of its toxic effect
Yeast selenium is expensive, and the cost input is relatively large, so planting selenium-enriched forage is a safe and low-cost method for producing selenium-enriched livestock products

Embodiment Construction

[0017] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0018] A method for planting selenium-enriched alfalfa, comprising the following steps:

[0019] (1) Fertilization for soil preparation: choose land with flat terrain, neutral or slightly alkaline soil, and a salt content of no more than 0.3% as the planting site. After the previous crops are harvested, immediately shallow plow and stubble removal, and then apply decomposed farmyard manure per mu 250kg, 20kg compound ternary fertilizer, 150g herbicide, plow 25-30cm deep, and rake the ground;

[0020] (2) Seed treatment: Soak alfalfa seeds in 50-60°C water for 30 minutes before sowing, take them out and dry them in the sun, then add rhizobia agent for seed dressing, use rhizobia agent 5g per kilogram of alfalfa seeds, mix well and immediately sowi...

Abstract

The invention discloses a method for planting medicago sativa rich in selenium and relates to the technical field of pasture planting. The method comprises the following steps: 1, soil preparation and fertilization; 2, seed management; 3, sowing; 4, field management; 5, cutting treatment; 6, harvesting. According to the method, the medicago sativa rich in selenium is planted and obtained by spraying compound selenium fertilizer onto the leaf surfaces, inorganic selenium is converted into organic selenium through in-vivo conversion of pasture, and the safety and absorbability after the pasture is eaten by livestock are high; through the application of herbicide and insecticide, the pasture output can be increased, and the pasture quality can be improved, thereby economic benefits are increased.

Description

Technical field: [0001] The invention relates to the technical field of grass planting, in particular to a method for planting selenium-enriched alfalfa. Background technique: [0002] Alfalfa is a perennial leguminous forage. Alfalfa has strong stress resistance and a wide range of adaptability. It can grow in various types of climates and soil environments. It has the title of "King of Grass". -The yield of fresh grass per mu in 5 years is generally 2000-4000 kg, and the yield of hay is 500-800 kg; the utilization period is long, the life span can reach 30 years, and the utilization period of field cultivation is as high as 7-10 years; strong regeneration , can quickly recover after mowing. Generally, it can be mowed 2-4 times a year, and the most can be mowed 5-6 times; it has strong palatability, and the stems and leaves are tender and delicious. Processing grass powder, used for compound feed or mixed feed, all kinds of livestock and poultry are the most favorite food,...
