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 1

[0019] A method for planting selenium-enriched Sorghum alba, comprising the following steps:

[0020] (1) Fertilization for site preparation: select sandy loam, clay loam or weakly acidic soil, apply 250kg of decomposed farmyard manure and 100g of herbicide per mu after weeding, then plow 25-30cm deep, and rake the ground;

[0021] (2) Seed treatment: Before sowing, choose a sunny day to spread the seeds thinly for 3 consecutive days. When drying the seeds, turn the seeds frequently to make them evenly heated. Soak the seeds in 40-50°C water the day before sowing;

[0022] (3) Sowing: When the temperature of 5cm on the soil surface reaches 15-20°C, it can be sown. Drill sowing or hole sowing is adopted. The row spacing is 40-50cm, the sowing width is 15-20cm, the sowing depth is 2-3cm, and the sowing rate per mu is 1.5-2kg. Cover the seeds with fine soil after sowing;

[0023] (4) Field management: combine watering and plowing for 2 times after emergence, and carry out thinni...

Abstract

The invention discloses a planting method for selenium-enriched sorghum hybrid sudangrass, and relates to the technical field of pasture planting. The planting method comprises the following steps of 1 land preparing and fertilizing; 2 seed processing; 3 sowing; 4 field managing; 5 cutting; 6 grazing. According to the planting method, the selenium-enriched sorghum hybrid sudangrass is planted and obtained by spraying compound selenium fertilizer on the leaf surfaces, inorganic selenium is converted into organic selenium in pasture, and therefore the safety and absorbability are higher after the pasture is eaten by live stocks; herbicide and pesticide are used, therefore, the pasture yield and quality can be improved, and the economical benefit is increased.

Description

Technical field: [0001] The invention relates to the technical field of forage planting, in particular to a method for planting selenium-enriched sorrel grass. Background technique: [0002] Sorghum grass is a new forage grass that was recently approved by the third National Forage Variety Approval Committee, based on the principle of heterosis by hybridizing sorghum and sudan grass. Sorghum grass combines the advantages of thick stems and wide leaves of sorghum and strong tillering and regeneration ability of sudangrass, and the heterosis is very obvious. Hay contains crude protein and high sugar content, suitable for silage. It can be used to raise livestock such as cattle, sheep, rabbits, geese and fish. The production performance is high-quality and high-yield, and the benefits are obvious. [0003] Selenium is not only an essential trace element for humans, but also an essential trace element for animals. Adding a certain amount of selenium to poultry and livestock ...
