Background

Fructus Pruni Salicina Lindl is a plant of Prunus of Rosaceae, and is also called Jiaqing seed, Bulin, fructus Pruni Salicinae, YUHUANG fructus Pruni Salicinae, or SHANLU. The fruits are ripe within 7-8 months, full, mellow, exquisite, brilliant in shape and sweet in taste, and are one of the favorite fruits. The plum is widely cultivated around the world, is sour in taste, can promote secretion of gastric acid and gastric digestive enzyme, and can promote gastrointestinal peristalsis, so that the plum has the effects of improving appetite and promoting digestion, and is especially effective for patients with achlorhydria, after-eating fullness and constipation. The amino acids such as serine, glycine, proline, and glutamine in fresh plum flesh have diuretic and repercussive effects, and can be used for adjuvant treatment of liver cirrhosis. The plum contains various nutrient components, has the effects of beautifying and lubricating the skin, has high content of antioxidant in the plum, and is named as 'super fruit' for resisting aging and preventing diseases.

The existing plum planting mode is to firstly carry out seeding, seedling raising, seedling transplanting and planting growth. The sowing is the beginning of the plum growth process, and the plum seeds can be enabled to emit better plum seedlings only if the plum seeds are well grown. Therefore, the sowing of the plum seeds is particularly important, firstly, the sown plum seeds cannot be empty seeds (namely rotten and bad seeds), and secondly, when the plum seeds are sown in the soil, a certain distance exists between the plum seeds and the plum seeds, so that the probability of fighting for nutrient elements in the soil between the plum seeds is reduced, and thus when the plum seeds emit plum seedlings, the plum seedlings can grow well.

The plum seeds are required to be screened before sowing, the screening mode is that the plum seeds are soaked by liquid medicine, empty seeds with light weight can float, other plum seeds sink or suspend in the liquid medicine, secondary screening is required for obtaining optimal seeds, the suspended plum seeds are taken out, and high-quality seeds with large weight are left. The seeding is carried out after the seeds are sunned for a plurality of times, so that the process is complex and the working efficiency is reduced.
