Alfalfa sprouts production technology

Axillary buds have a short growth cycle, high yield, simple cultivation facilities, no application of chemical fertilizers, pesticides, and no pollution, and are pure natural green vegetables. Eat its tender stems, leaves, nutritious, containing protein, a variety of amino acids, vitamins, also contains plant saponin, strong alkali, can reduce the body's cholesterol, is conducive to the prevention of coronary heart disease, there is a clear role in health care, with Better promotion and development prospects.

First, venues and facilities

The spring-autumn sprouts can be produced in plastic greenhouses, shady pergola, and indoors with good ventilation, cooling and lighting. In winter, they can be produced in greenhouses and other indoor facilities with heating facilities. The growth rack uses a three-dimensional cultivation frame made of wood or steel. It is 1.5 meters long and 0.6 meters wide. The cultivation racks have a spacing of 40-50 centimeters per floor and can generally be made into 4-storey racks. Seedling trays use standard plastic seedling trays (0.6 m 0.25 m 0.05 m) and can also be made of wood, metal, etc., but the bottom must be flat and porous.

Second, the selection process

The seeds for the production of axillary buds should use new seeds such as alfalfa, sweet peony and dongdong wolfberry that were harvested in the same year. Before sowing, the seeds were air-dried 1-2 days after the panning, remove impurities and pod seeds, soaked in warm water at 20°C for 20 hours, then drained and ready for sowing.

Third, the production method

Before sowing, disinfect and wash the seedling tray, spread two layers of newspapers at the bottom of the pan, or use 3-5 mm thick perlite as the bed base. Drench with water and spread the seeds evenly on it. The seeding rate is 50 g per plate.

After sowing, each 5-8 seedlings were piled together and stacked to give rise to germination. There is a space of 3-5 cm between each seedling plate for air ventilation and even emergence. Seedlings covered with moisturizing sacks or wet grass curtains, light and germination, each morning and evening spray cold water 1-2 times. To keep the seeds moist, when the seedling height is 0.5-1 cm after 2-3 days, the germination is ended, the seedling disks are separated, and the light is kept on the shelves to maintain the room temperature at 17° C.-22° C. When the temperature exceeds 27° C., the seeds are easy to mold. Shade nets should be used in summer production to increase ventilation. When the temperature exceeds 28 °C, ventilation should be promptly cooled to prevent rot and mildew. Spray water l-2 times a day, so water is not suitable. When the seedling height is 3 cm, it can shine light, but avoid exposure. In production, often due to insufficient air humidity or insufficient illumination, sometimes the seed coat does not fall off. At this time, water spray can be performed first. After the seed is wet, the seed coat is combed off with a comb.

Fourth, harvest and sell

Eight to ten days after sowing, the cotyledon buds are green, the hypocotyls have been as long as 3.5-4 cm, and the white stems of the hypocotyls are about 1 mm thick. The cotyledons are sufficiently enlarged and flattened, and the young seedlings can be harvested when they are tender. When harvesting, the seedlings are uprooted, packed in small boxes or sold in whole trays. The general yield is 7-8 times the seed weight.
