A kind of high-efficiency propagation method of lumpy yam seed potato seedbed

Abstract

The invention discloses an efficient seedbed breeding method of lump seed yams and belongs to the technical field of seedling breeding. The efficient seedbed breeding method includes the steps of selecting lump seed yams without damage caused by diseases and pests and dicing according to normal sowing requirements, performing protective treatment on the cut surfaces of the seed yams by using plant ash or lime powder, and accelerating germination of the diced seed yams on a germination accelerating seedbed in a greenhouse or a small arch shed, next, dividing each germinating seed yam into 3-4 seed yam blocks with buds, sowing the seed yam blocks with buds in a fertilized seed yam breeding seedbed, carrying out seedbed management by using a lump seed yam seedbed breeding technique after the emergence of seedlings, and harvesting the seed yams before frosting in autumn. The method is capable of breeding 70000 yams per mu. The efficient seedbed breeding method is used for breeding the seed yams by dicing the yams twice, and therefore, the breeding coefficient of the lump seed yams is greatly increased and the purpose of saving the seed cost is achieved. The efficient seedbed breeding method has the advantages of high breeding coefficient, high breeding efficiency, great saving of the seed yam breeding cost and improvement of the seed yam breeding efficiency.

Description

Technical field [0001] The invention relates to a method for efficient propagation of massive yam seed potatoes, which is a new method for high-efficiency and rapid propagation of seedbeds by using massive yam seed potatoes, and belongs to the technical field of seedling breeding. Background technique [0002] As a health food, yam has a history of more than 2,000 years. Its nutritional value, medicinal value and disease resistance mechanism are gradually being discovered and confirmed, and it is increasingly favored by consumers and has a very broad market prospect. Yam is a traditional local specialty of Jiangsu Province. At present, the planting area of ​​yam in Jiangsu Province is about 200,000 mu. It is mainly distributed in the alluvial plains of northern Jiangsu and the riverside and coastal silt plains of central and southern Jiangsu. The area bordering Anhui is one of the four main producing areas of yam in my country. Yam is a high-input, high-yield crop with a planting...

AI Technical Summary

Problems solved by technology

In recent years, Jiangsu Province has increased the introduction and application of new varieties of blocky yams, but most blocky yams do not bear zero seeds, and the thick and short shape of blocky yams leads to extremely low reproduction coefficients, which greatly limits the development of blocky yams. For the application of new yam varieties, there is an urgent need for a method for the propagation of lumpy yam seed potatoes with a higher propagation coefficient
