In spring, the yellow land should be excavated in time when the stems and leaves on the ground are yellow before and after November of that year. When the excavation is completed, a 35 cm deep ditch should be opened at one end of the crucible, and the rhizomes should be carefully removed in turn; the processed ground yellow should be processed into the ripening ground using a special oven to become a commodity. Yellow leaves, flowers, rhizomes can be used as medicine. In the later period of the growth of Rehmannia glutinosa, choose yellow-leaf plants that are robust and disease-free. Pick some leaves properly and dry them in the shade. The yellow leaves treat evil sores and hand and foot spasms, and they have the effects of Xiaoke and treatment of kidney deficiency and low back pain. Therefore, harvesting should be carried out at an appropriate time. The harvest of yellow flowers should be at the flowering stage, choose sunny days, combine the buds to pick flowers and buds, and dry them in the shade. The best harvest time for rhizome of Rehmannia glutinosa is from the end of October to the beginning of November. After the yellow ground has gradually grown yellow to stop growing, it can be harvested by cutting off the stems and leaves of the shoot with shovels or sickles. Be careful not to cut too deep so as not to damage the root. After the ground is cut off, the cut stems and leaves are raked to one side with tweezers, exposing the surface to facilitate the harvesting of the roots. Use a hoe or rake to excavate at one end of the rake. The groove depth is about 35 cm. The depth of digging is good for not damaging the rhizomes, and yellow is easy to break, so be careful when excavating. The picking process also minimizes root damage. Each mu can receive 1000 to 1500 kilograms of fresh yellow, high yield per mu up to 2000 ~ 2500 kg.
