One, the cultivation process
1, select beans: clean water, wash, pay attention to the floating beans (mung beans, soybeans, peas) all removed, these floating beans are immature or have been deteriorated, the germination rate is extremely low.
Bean sprouts
2, with a cylinder, or a large plastic box, or other containers (material does not matter, clean can be, the bottom can be drained), lay a layer of clean sand about 5CM thickness, will be washed and has been soaked to expansion of cracked beans evenly spread a layer of sand, can not be too much, otherwise it is easy to bad. Beans and then evenly covered with a layer of clean sand, thickness of about 1CM can be.
3, watering several times a day, to maintain humidity, but can not let the water retention.
4, a few days after the bean sprouts will arch out. Just wash the sand away in the water.
Two, technical points
1, remove the bad beans when cleaning.
2, container drainage should be good, never let the beans soak in water, but to maintain enough humidity.
3, do not let the beans see the sun, or immediately turn green. Cover with sand to avoid sunlight, if you are not sure, you can cover the container with a lid.
4, beans grow quickly after germination, so harvest in time.
Three, notes
1, choose beans: to choose full without trauma of the excellent bean seeds, generally available on the market are left over by the selection of seeds, so the bean sprouts born very short on the long roots! So be carefully selected, generally a pound of beans can be selected about half a pound of good beans! To save yourself the trouble, buy beans straight from the seed store.
2, do not let the bean sprouts and sunlight contact, this will make it early root yellow.
3, water hard every day! Water every 2 hours or so, and water at night, preferably at intervals of no more than 8 hours or more.
4, try not to use cold water, use room temperature water.
4, recommended tools
Kettle: sealing good, permeability is good, disadvantage: manual watering.
Bean sprout machine: automatic watering.
