Net yarn water radish bud technology

First, cultivation equipment

Frames are made of wooden strips or thick wire, cast in 1 to 2 layers of screens to make screens. The meshes cannot leak through the radish, but the root can pass through.

Second, environmental disinfection

Closed doors and windows, 1 g solid sulfur per square meter, lit fumigation 4 to 12 hours, and then open the doors and windows for ventilation. Mesh is soaked with 3% lime, washed and rinsed with water for 2 to 3 times. The cultivating vessel is soaked with 3% lime water and then rinsed with water.

Third, choose

The production of radish sprouts should use high-quality radish seeds full of grains and large heads, such as Dahongpao, Daqing radish, Chuanxinhong, Manyuanhuazi, and green manure radish. After removing impurities and insufficient seeds, wash the dirt outside the seed coat with water. Soak it with water twice the seed volume for 3 to 4 hours. After soaking, wash the seeds 2 or 3 times, wash away the mucous from the seed surface, and then remove and drain.

Fourth, sowing

Wash the soaked radish seeds, wash them out, drain the excess water, and spread evenly on the gauze. The density is 250-300 g/m2. The mesh yarn should be placed in a flat bottom container filled with nutrient solution, and the nutrient solution should be about 0.1 cm above the mesh surface. The nutrient solution is 0.1% urea solution or ammonium bicarbonate solution. After sowing, the cover film is kept warm and moisturized.

V. Management

Remove the film 2 or 3 times a day for 30 minutes each time to allow the seeds to ventilate and ventilate. After the seeds germinate, the film can be removed. The level of the nutrient solution is equal to that of the mesh yarn, which is favorable for the seeds to smash down after germination.

During the growth process, as the leaf surface evaporates, nutrient solution should be promptly added to keep the roots moist, for 7 to 10 days. When the cotyledon is flat and the true leaves are not emerged, they can be harvested.
