One, soybean selection
1, select beans: soybean evenly spread over the seedling tray, carefully select the first step of the beans, to have wormholes, black, particles are not full of pick out do not.
2, soaking beans: soybeans rinsed once, into a clean oil-free container, water added to soybeans above about 8 to 10 centimeters, soak for 10 hours.
3, spread the beans: the seedling tray clean, put a piece of water-soaked seedling paper, and then clean soybeans evenly spread all over.
4, rinse: summer general soak 10 hours or so beans good has grown a lot, then immediately rinse with running water, miscellaneous beans discarded.
Two, daily management
1, temperature: soybean in the temperature over 30 degrees will affect the germination, only in the appropriate temperature will not be corrupt, the germination of the appropriate temperature at about 28 degrees.
2, watering: watering is the most important part, to keep wet at all times, but the water can not be too much, the bottom of the disk can not leave water, otherwise it may rot the roots.
3, light: soybean must avoid light seedlings, sprayed with water, seedling tray to cover a thick layer of moist gauze.
4, germination: soybean sprouts watering to be watered through, cotton cloth should also continue to spray moistened and covered with it, generally to the next night will be able to send out fine shoots to.
Three, notes
1, when the bean sprouts grow to 15 millimeters long when watering to penetrate without leaving a dead end to prevent red roots, rotten roots.
2, master the water temperature, regular watering, water is not cold and hot, in order to prevent the bud root into reddish brown.
3, watering water temperature should not be too high, the head of water should not be too short, otherwise it will make the bean sprouts only long roots not long stalk.
4, buds 50 millimeters long should increase the water temperature, increase heat to prevent sprouting roots black.
5, when the bean sprouts will be good should reduce the water temperature of the last three watering, germination is completed in time to take out, in order to prevent the middle of the bean sprouts rot phenomenon.
