Problems solved by technology

[0002] Potato is not only one of the main food crops in my country, but also an important feed and industrial raw material crop. It has high economic benefits. However, since potatoes are asexually propagated crops, if they are planted for a long time, the characteristics of the variety will be seriously degraded, and the result will be a significant decrease in yield.

Embodiment 1

[0020] A method for multiplication of virus-free seed potatoes includes the following steps:

[0021] ①Site selection and soil preparation: select newly reclaimed sandy loam with a deep soil layer, an altitude of 2000m, a soil organic matter content of 1.0%, and a pH value of 5, turn the soil deep, remove debris, and level it;

[0022] ② Seed potato preparation:

[0023] a Variety selection: choose the original seed that is suitable for local planting and does not rot;

[0024] b Seed tuber treatment: the original seed is continuously seeded for 4 hours, first mix 100kg of talcum powder with 400g of 75% chlorothalonil or 72% carbendazim, and then mix the talcum powder mixture with the original seed The seed dressing ratio of the mixture of the talcum powder and the original seed is 1:10, and finally the original seed after the dressing is covered with a film for accelerating germination, and seeding can be carried out after germination;

[0025] ③Sowing:

[0026] a Sowing time: in the m...

Abstract

The invention discloses an expanding propagation method for detoxified potato seeds of potatoes. The method mainly comprises the following steps: selecting a land and carrying out soil preparation, preparing potato seeds, sowing the seeds, carrying out intertillage management, preventing and treating plant diseases and insect pests, harvesting in proper time and carrying out expanding propagation breeding. The planting method of the detoxified potato seeds cultured by the method is reasonable, is easy to grasp and is easy to operate; the emergence rate is high, and plants in a whole growth period have vigorous growth tendency, low occurrence rate of the plant diseases and insect pests and rapid growth speed; meanwhile, the harvested detoxified potato seeds have small individual difference and more than 95% of superior products can be obtained; after the detoxified potato seeds are planted, the adaptability is strong and the diseases resistance is strong; the production increasing effect is extremely remarkable, and the yield per Mu can be improved by 2-3 times when compared with that of a plot without the detoxified potato seeds; the economic benefits are high; the detoxified potato seeds are suitable for being planted on various mountain lands and fields, have a wide application range and are suitable for large-area popularization and breeding.

Description

technical field [0001] The invention belongs to the technical field of potato planting, and in particular relates to a method for multiplying virus-free seed potatoes. Background technique [0002] Potato is not only one of the main food crops in my country, but also an important feed and industrial raw material crop. It has high economic benefits. However, since potatoes are asexually propagated crops, if they are planted for a long time, the characteristics of the variety will be seriously degraded, and the result will be a significant decrease in yield. . In recent years, by cultivating virus-free seed potatoes and establishing a breeding system for good varieties, a key problem restricting the development of the potato industry has been effectively solved. Virus-free seed potatoes are cultivated into regenerated plants by peeling off potato shoot tips, and after virus serological detection Non-toxic plants, tissue culture and rapid propagation to produce test-tube seedli...
