Asparagus
1, Plant introduction
0 Asparagus, (Latin scientific name: Asparagus cochinchinens (Lour.) Merr), alias: Sanbai Rod, Wuzhu , Silk Winter , tiger tail root, Asparagus grass , tomorrow winter. Climbing plants. The roots are spindle-shaped in the middle or near the end, with most of them 3-5 cm long and 1-2 cm thick. The stem is smooth, often bent or twisted, and can be as long as 1-2 meters long, and branches have edges or narrow wings. Leaf-like branches are usually clustered every 3, flat or slightly sharp triangular due to the shape of the central vein keel, slightly sickle-shaped, 0.5-8 cm long and about 1-2 mm wide; the base of the scale-like leaves on the stem extends to hard spines with a length of 2.5-3.5 mm, and the spines on the branches are shorter or less obvious. Flowers are usually grown in every two axillary and light green; the peduncle is 2-6 mm long, and the joints are generally located in the middle, and sometimes the position changes; male flowers: the quilt is 2.5-3 mm long; the filaments are not attached to the quilt; the female flowers are similar in size to the male flowers. The berries are 6-7 mm in diameter, red when ripe, and have 1 seed. The flowering period is May to June, and the fruiting period is August to October.
2, habitat of origin
is distributed in eastern China, , central and southern , Hebei, Henan, Shaanxi, Shanxi, Gansu, Sichuan, Taiwan, Guizhou and other provinces and regions. It mostly grows in wetlands, hilly shrubs or hillside grass.
3, application value
Asian roots are commonly used Chinese medicines, which have the effects of nourishing yin and moistening dryness, clearing fire and relieving cough. At the same time, it also has antioxidant, delaying aging, lowering glycemic, antibacterial, antitumor, antitumor, anti-suppression and expectoration. In addition, Asparagus roots contain 33% starch, 4% sucrose and various other nutrients. As a commonly used Chinese medicine, the market demand has always remained high. This has also led to the corresponding development of the seedling cultivation and planting industries of this medicine. As for the current seedling cultivation situation, there are still many problems. At present, Asparagus mainly reproduces through seeds and divisions. seeds reproduce , resulting in an extended reproduction cycle, increased management costs, unstable emergence rate, and sometimes even hybridization mutations in offspring, affecting the quality of Chinese medicinal materials. The reproduction of the branch requires a large number of roots as reproductive materials. Not only does it have a low reproduction coefficient, it also invisibly increases the cost of materials, which is not conducive to large-scale promotion and cultivation. The rapid breeding of seedlings using plant non-test tube rapid breeding technology invented by researcher Li Changxiao has solved these problems well. Plant non-test tube high-efficiency rapid breeding technology (TERNPC) is essentially an asexual breeding —— (by cutting a high-quality mother plant, one leaf and one bud, it can be cultivated into a complete plant). Compared with traditional seed reproduction, this technology greatly shortens the reproduction cycle and can ensure the high-quality genes of the original plants to the greatest extent and have no mutations. Compared with branch breeding, this method has a higher reproduction coefficient and is more conducive to large-scale expansion. It has the characteristics of low cost, short cycle, high reproduction coefficient, small influence due to seasonal factors, low cost of large-scale production, high survival rate, and simple management. It can meet the market's seedling needs with low cost and high returns. It's a good investment project.
