Embodiment 1

[0013] In 2011, the three-stage breeding of healthy purple yam mini-potatoes of 5 acres was carried out in the Zijinteng Potato Industry Professional Cooperative in Caozhuang Village, Dashahe Town, Fengxian County, Xuzhou City, Jiangsu Province.

[0014] (1) The stage of dicing and raising seedlings in the greenhouse of purple yam seed potatoes: On March 15, the excellent varieties of Xunong Ziyao were selected, and the three-stage seedling method was used to improve the quality of purple yam potato seedlings, and strive for more seedlings, uniform seedlings, and strong seedlings. , early seedlings, laying the foundation for the production of a large number of high-quality, healthy miniature purple yam seed potatoes in autumn. Choose potato pieces that are disease-free, insect-free, and frost-free, and cut purple yam seed potatoes into pieces, with a standard of 50-60g / piece. Then mix the original carbendazim powder and quicklime powder in a ratio of 1:3 for disinfection and s...

Abstract

The invention discloses a three-segment healthy purple micro yam breeding method, and belongs to the field of yam seedling breeding methods. The three-segment rapid yam seedling breeding method is utilized in the seedling growing method, healthy micro yam seedlings without soil-borne diseases and yam-borne diseases are produced from purple yam seedlings without yam tubers and are non-contact with soil, factorial production is implemented, a large amount of healthy micro yam seedlings are bred intensively, breeding efficiency of purple yam seedlings can be improved, and production cost can be reduced. Yield of purple yams is increased by 15 to 20% per mu, original fine species and yield of the purple yams are recovered, and planting benefits of soil per unit area is increased.

Description

technical field [0001] The invention relates to the field of breeding methods for yam seed potatoes, in particular to a three-stage breeding method for healthy purple yam mini-potatoes. Background technique [0002] Chinese yam (Dioscorea opposite Thunb) is a perennial herbaceous entwined vine of the Dioscorea family, Dioscorea, and is a highly efficient economic crop that can be used for both grain, vegetable and medicine. Purple yam is rich in anthocyanins and has a wide range of uses. It can be used as a delicacy on the table and as a health care medicinal material. Regular consumption of purple yam can reduce blood pressure, blood sugar, anti-aging and longevity, strengthen the brain and strengthen the body's immunity. . However, unlike common yam, purple yam can produce yam beans (surplus seeds or pearl buds) at the leaf nodes during growth, and then use a large number of yam beans in the following year to purify and rejuvenate its excellent species. At present, the p...
