Calyx is famous for the king of pasture. It not only produces high grass yield, but also has excellent grass quality. It is also rich in crude protein and rich in essential amino acids. The content of crude protein in dry matter is 18.8%, which is close to half that of soybean cake and about 1 times higher than that of corn. It has good palatability and can be fed on green, silage or dried hay. The young quail feeds pigs, poultry, rabbits, and herbivorous fish and is a supplement to protein and vitamins. A strong root system is a good soil and water conservation plant. Long nodules on the roots can fix nitrogen in the air. Besides satisfying their own needs for nitrogen, they can also increase the content of nitrogen in the soil. Indigo hay can be used for animal feeding for a long period of time. High quality alfalfa hay retains green and blue color, aromatic smell, soft texture, leaves do not fall off, and palatability is good.

Alfalfa is an annual or perennial legume herb belonging to Leguminosae. Hi warm and semi-arid climate. The average daily temperature of 12°C to 20°C is the most suitable for growth. The root system is well developed and deep into the soil. It can fully absorb the deep water in the soil, so it has strong drought resistance. Lax soil requirements. During the growth period, the water is most avoided. Continuous flooding for 1 day and 2 days means a large number of deaths. Therefore, good drainage is required, and the groundwater level is less than 1 meter. Salt-tolerant, adult plants have a salt content of 0.3% and grow well below 0.2% sodium chloride.

1, sowing. Before sowing, a soil preparation of 3,000 to 5,000 kg of farmyard fertilizer per acre was applied, and 50 kg of calcium phosphate was used as a base fertilizer. The seeds of alfalfa are small, fine soil preparation is required before sowing, and the soil moisture content is maintained. In the poor soil, appropriate amount of manure and phosphate fertilizer should be applied as base fertilizer. It can be sown all year round. Drilling is generally used. The row spacing is 30 cm to 40 cm. The sowing depth is 1 cm to 2 cm. The sowing volume per acre is 1 kg to 1.5 kg.

2, management. Seedling growth is slow, vulnerable to weeds, weeding should be timely. In the early spring before returning to green or after the previous cutting, cultivating loose soil, top dressing, and watering are carried out. After topdressing, topdressing was performed once, using phosphorus and potash fertilizers as main nitrogen fertilizers, and the ratio of N, P and K was 1:5:5.

3, harvest. Each year, it can be castrated 3 to 4 times, and it is harvested from the end of the bud to the early flowering period. The height of the alfalfa is 5-7 cm. General yield of 1,000 kg of hay hay? 2000 kg, high yield up to 4,000 kg. Usually 4 kg? 5 kg of fresh grass drying hay 1 kg, drying hay should be cast in 10% of the plants when the flowering, leaving the sting height is about 5 cm is appropriate.
