1. Rootless bean sprouts technology - selection of beans selection of ripe, full of particles, high germination rate, in order to sprout the momentum of strong bean seeds. Remove cracked beans, broken beans, tender beans, insect mouth beans and other debris. Storage heat away from the oil beans, the next year beans, can not be used for the production of rootless bean sprouts; this bean is not only a low germination rate, and even will not germinate. And in the production process will be poisonous rot.
2. Rootless bean sprouts technology - soaked beans selected bean seeds poured into the tank, full of water (tap water, well water, etc. can be), up and down, stirring, with a wire strainer to float up the beans and other debris, and then repeatedly wash with water, soak for half an hour, and then poured into a container, container leakage holes shall be used to fill with bushels of strips, but can not be filled too tightly or too loosely, the standard loosening of the smooth flow of both water and will not leak out of the bean seeds appropriate. The standard of looseness and tightness is that the water can flow smoothly and the bean seeds will not be missed. A diameter of 64 centimeters, 66 centimeters high barrel can be loaded with 16.5 to 17.5 kilograms of seed, generally loaded to 1/3 of the container. seed into the container, but also drenched in water once.
3. Rootless bean sprouts technology - drenching this is a key part of the production of good bean sprouts. Although there is a period of dormancy after the beans are matured and harvested, they are still breathing. This phenomenon appears to be particularly vigorous when sprouting. If the heat generated by its respiration is not emitted in a timely manner, the bean sprouts will rot and deteriorate giving off a sour odor. The number of times and how much water, according to seasonal climate change and increase or decrease. Summer temperatures are high, generally four hours a shower, a shower twice; spring and fall climate is mild, suitable for the growth of bean sprouts, can be four to five hours a shower; winter weather is cold, the growth of bean sprouts is slow, the indoor temperature should be increased. Conditional places, the indoor temperature should be maintained at 22 to 25 ℃, the number of drenching every six hours, a drenching once. But to use warm water, to master the water temperature. Do not have high and low. Water temperature is too high will make the bean sprouts grow slowly, appear curved, gray color, commonly known as "old mouth", the growth period is long. What's more, it is necessary to prevent a hot burst of cold burst. In short, mixed with hot water to be uniform, to feel gentle, the temperature of 22 ℃ is appropriate, before drenching with a thermometer to measure the water temperature, do not just estimate.
(Drenching method: one hand grasps the drenching bucket from the tank full of water, to the palm of the other hand slowly sprinkled, like watering flowers, the action as slow as possible, to sprinkle open sprinkled evenly, not to rush, pouring, to prevent the wash over rushing broken bean sprouts, affecting the growth. Drenching should be sufficient, while drenching the container of water from the leakage hole, but also to make the container full of water over the bean sprouts).
4. The production process of the first day of seed soaking, the second and third day in the morning, but also the container of bean seeds poured into the tank to soak once (warm water in winter), because of the different germination potential of the bean seeds, containers of bean sprouts in different locations of the water, light, air, heat are different, the speed of germination is not consistent, after a few times of panning, basically change the container of the upper mouth of the buds long, around the bottom and the bottom of the buds of the short situation. Strive to bean seed bud germination uniform and neat. Method of operation: pour the bean seeds into the water tank, with the hands up and down stirring mix evenly, with a scorn basket fished out, into the container, in addition to no germination, the rest are covered with bushels (cold days with straw bales), regardless of seasonal changes, can only be washed once a day, can not be washed, otherwise it will damage the bean sprouts and affect the growth. To the morning of the fourth day, do not have to wash under the tank, only have to be watered on time, so that the bean sprouts in the container growth, commonly known as "sitting in the bucket". In the soaking seeds to buds 1.8 centimeters long, about three and a half days in winter, other seasons as long as three days at most on the line.
