Problems solved by technology

[0003] At present, there are generally two types of plant breeding: asexual reproduction and sexual reproduction. Chinese yam generally adopts asexual reproduction technology, including terminal bud propagation, tuber root propagation and zero-surplus seed reproduction. The decline of disease and stress resistance is generally carried out by the combination of zero surplus seeds and root tuber propagation, but the zero surplus seeds have a long dormancy period, usually harvested in October-November, and can only germinate after sowing in April of the next year. The body sleep period lasts for 4-6 months

Embodiment 1

[0018] A kind of breeding method of iron rod yam, comprises the steps:

[0019] 1) At the end of October of the first year, select high-quality single yam zero-yuzi. It is required that the grains are large and full, and the single-grain weight of zero-yuzi should be more than 2 grams. After γ-ray irradiation treatment, it should be stored in sand for about two months;

[0020] 2) At the end of December, use the zero residue stored in step 1) with H2O with a mass concentration of 2-5%. 2 o 2 Soak for 20-24 hours, then rinse with distilled water 2-3 times, evenly buried in fine sand; Irrigate with nutrient solution once a day to keep the sandy soil moist until the yam seeds sprout;

[0021] 3) In mid-February of the 2nd year, plant the Lingyu seeds that germinated in step 2) in a yam selection field with consistent soil and fertilizer conditions and good irrigation and drainage, and carry out film-mulching treatment, and then conduct field management; After Huang, collect th...

Abstract

The invention discloses a breeding method for iron stick yam. According to the invention, a mode of combining bulbil and earthnut is adopted for breading; the selected bulbil is disinfected and is processed with a nutrient solution; and the period of dormancy of the bulbil is released to quicken the sprouting of the bulbil for breeding. According to the method, the bulbil is adopted for breeding, so that the stable heredity of the excellent variety shape can be ensured, and the dormancy of the yam bulbil is broken through certain process of the bulbil, the dormancy is shortened to be 2-3 mouths from original 4-6 mouths, and the plating time is February every year instead of the April every year; the quality and yield of the yam can be improved by prolonging the childbearing period through a mulching method; and at the same time, the method can be used for improving the bud ratio of the bulbil to 56-70% so as to improve the yield.

Description

technical field [0001] The invention relates to the field of agricultural planting biotechnology, in particular to the planting of Chinese yams. Background technique [0002] Yam is a perennial twisting herb of Diospinaceae. It is one of the characteristic economic crops that combine medicine, vegetables and grain. It has high edible and medicinal economic value and industrial development potential. The tubers of yam are delicate in meat and rich in nutrition. They not only contain rich starch, protein, vitamins and sugars, but also contain a variety of amino acids and minerals necessary for the human body. They have anti-virus, anti-aging, Anti-tumor and other health effects. Yam can not only be used as food to provide a large amount of carbohydrates for human beings, but also provide biologically active ingredients, which can enhance immunity for the human body, inhibit cancer cells, regulate gastrointestinal function, improve antioxidant capacity, reduce blood sugar and ...
