A large amount of research data shows that black-bone chicken is rich in vitamins, trace elements, unsaturated fatty acids, melanin, selenium, and sulfur. The seeds of some black crops, such as black corn, black sesame, black wheat, black beans (commonly known as black beans), also contain trace elements, vitamins, amino acids, and iodine, selenium, amylopectin, and soluble pigments. A recent feeding experiment conducted by China Agricultural University showed that the black-bone chicken only needs to feed once with the above-mentioned black mixed feed in the morning, and the content of unsaturated fatty acids, vitamins, and trace elements in the chicken can be increased by 0.5 to 2 times that of the black-bone chicken fed ordinary feed. The melanin, sulfur, and selenium contents increased by about 3.5 times year-on-year, and the growth status of black-bone chickens was significantly improved. The medicinal functions such as nourishing impotence and nourishing qi were also significantly improved.
A seedbed or seedling bed is the local soil environment in which seeds are planted. Often it comprises not only the soil but also a specially prepared cold frame, hotbed or raised bed used to grow the seedlings in a controlled environment into larger young plants before transplanting them into a garden or field. A seedling bed is used to increase the number of seeds that germinate.
