Alfalfa is a kind of alfalfa grass, the flowering form is very beautiful, and the next step is to introduce you to the introduction of alfalfa farming.
Biological characteristics of alfalfa
Alfalfa is a perennial herbaceous plant, and its hay production ranks among the top of a variety of leguminous pasture grasses, and its nutritional composition is complete, rich in protein, trace elements and more than ten kinds of vitamins. The main root of alfalfa is very long, generally can reach into the soil below 3-5 meters, and the deepest can reach about 10 meters. The lateral roots are well developed, and the stems are erect and smooth, 60-100cm high, with three leaflets, obovate-orbicular, long and smooth petioles and large stipules. Flowers purple, racemes, seeds kidney-shaped, thousand grains weight 1.5-2.5g, two or three years after sowing to reach the peak growth, life expectancy can be maintained for 10-20 years, or even 40 years.
Sex like warm semi-humid climate, very drought-resistant, intolerant of waterlogging, strong cold resistance, the soil requirements are not strict, PH6.5-8.5 calcium-rich hustle or sandy loam is most suitable. In poor soil, it is advisable to apply a moderate amount of stable fertilizer and phosphate fertilizer as a base fertilizer to facilitate the formation of rhizomes.
Alfalfa can be sown all year round.
Clover's flower language: luck.

Legends about clover have a long history, some say it is Adam and Eve from the Garden of Eden to bring gifts to the earth; there are also said that the name of the lucky grass is derived from Napoleon,

What to look for in alfalfa farming?
Land selection: you should choose fertile land with a soil layer of 1m or more, loose, with good drainage and permeability. Alfalfa grass is drought-resistant, but afraid of flooding, alfalfa land flooded for 24 hours, 80% of alfalfa grass will die.
Adaptation area and seed selection: alfalfa grass cannot be farmed in areas where the fertility period is less than 85 days.
Land preparation and sowing:
1. Before sowing, deep turning once, rotary plowing once, once fishing level and suppression, let the land under the tight upper loose. Remove stones over 2cm.
2. Sowing machinery selection: alfalfa should be sown in fine quantities.
3. When the soil moisture is poor, spray irrigation is sufficient before and after sowing.
4. Sowing method: sowing volume: 1.5-2 pounds/mu, width 60cm row spacing 15-20cm sowing depth 1.5-2cm
5.
Weed control: after sowing to the seedling period, every year after the return of green, after each harvest should pay attention to weed control. Available artificial plucking or chemical weeding method. Chemical weed control can be sprayed with alfalfa-specific herbicides, and pay attention to the ban within 14 days before harvest.
Drainage and irrigation: alfalfa root system into the soil deep, drought resistance. However, timely watering in the dry season and after each mowing can significantly improve yield. The alfalfa root system is not resistant to flooding, so the floodplain should pay attention to timely drainage during the rainy season.
Fertilizing: alfalfa has rhizomes, which can fix nitrogen in the air and provide nitrogen for itself,
so it should be mainly applying phosphorus fertilizer and appropriate potash; however, in the barren wasteland, saline and alkaline land, and the place where soil nitrogen content is low, it should be applied a certain amount of urea to be seed fertilizer at the time of sowing. In the seedling period of alfalfa growth or every year after the return of green, the root system nitrogen fixation capacity is weak, and a certain amount of nitrogen fertilizer can improve its yield.The above is the introduction of alfalfa,
I hope you can help.
