Introduction to the growth of alfalfa

Alfalfa has a wide adaptability to soil, but is suitable for planting in soft sandy loam soil. my country has a wide planting range, mainly distributed in Inner Mongolia, Sichuan, Guizhou, Guangxi, Hubei, Jiangsu, Fujian, Xinjiang, Gansu and other places.

Alfalfa growth cycle

Alfalfa likes a warm and humid climate, is drought-resistant, cold-resistant, and heat-resistant. It has wide adaptability to soil and climate. It can be sown all year round and has tenacious vitality. . It can be used for soil and water conservation, sand prevention and sand fixation, slope protection and mountain greening. The growth cycle of alfalfa is very short, generally only 25 days from sowing to harvest

Alfalfa growth rate

1. Swelling is the initial stage of seed germination. 1. The first action after the seeds are sown in the soil is that the seeds will become saturated after absorbing water. Once the seed has absorbed 125% of its own weight, it breaks through the seed coat and germinates. 2. Germination is the second stage of seed germination, which is manifested by various weight changes in the seed body. The storage material is transformed, causing the embryo volume to expand, and the tip of the radicle breaks through the seed coat and extends outward, which is also called "white exposure" or "broken chest". 3. After germination, the embryo continues to grow. When the radicle and embryo protrude from the seed coat and develop to a certain extent, it is called germination. This is the third stage in the growth process. 4. Alfalfa can germinate at temperatures above 3°C, but the ideal germination temperature is 18-25°C. If it can meet its growth standards, you can see its tender green shoots in about 20 days. Alfalfa grows quickly.

Alfalfa growth cycle management

The yield of alfalfa per mu is generally 2000 to 4000 kilograms, and the yield of hay is 500 to 800 kilograms per mu. In areas with better conditions, the hay yield per mu can reach 700 to 800 kilograms. Temperature management: Alfalfa has a wide adaptability to temperature, and can grow and germinate from a low temperature of minus fifteen degrees to a high temperature of forty degrees. The most suitable temperature is between five and thirty-five degrees. Fertilization management: Appropriate amount of nitrogen fertilizer can be applied during the seedling stage of alfalfa to promote growth. At the same time, after each mowing, top dressing can be performed when watering, mainly using phosphorus-potassium compound fertilizer. In addition, fertilizers containing trace elements such as sulfur, boron, and molybdenum can also be applied to increase yields.
