In crop production, potato is generally asexual growth process from potato block to potato block. The whole growth period of potato can be divided into dormancy period, germination period, seedling period, hair growth period, potato growth period and maturity period.
Potato dormancy: Newly harvested potato tubers must germinate after a certain period of time under suitable conditions. This period is called dormancy, and this phenomenon is called dormancy. The dormancy of the tuber actually starts from the moment when the tuber begins to enlarge, and it is harvested from the decay of the stem and leaf after planting, and is considered to enter the dormancy period. To measure the length of dormancy of a species, the tubers harvested at physiological maturity should be used as the standard. The length of the dormancy period is determined by the genetic characteristics of the species and the temperature of storage. At room temperature, some species have a dormant period of only one month, while others last for four to five months.
The significance of potato dormancy in production: Potato tubers can remain dormant for a long time if they are stored at a low temperature of 2°C-4°C. When the temperature reaches above 10°C, the tubers easily germinate through natural dormancy. For the same species, the dormancy period of young tubers is longer than that of full maturity, and the micro-seedlings are longer than the dormant period. Therefore, using this dormant law, according to needs, artificially controlling dormancy can make fresh canned potatoes extend the market supply time. Processing special potatoes to extend the processing period. Seeds of potato in order to control the break dormancy, to promote germination of buds, is conducive to early sowing, early emergence, improve the field emergence rate and uniformity.
When potato seeds are about to come down, the method of breaking dormancy is used: Gibberellin is commonly used in the production of germination, but the concentration and processing time of the gibberellin must be strictly controlled to avoid excessively high concentration and affect the photosynthetic efficiency of plants, resulting in reduced yield. The concentration of gibberellin used is generally 5-10ppm soaked with whole potatoes for 5-10 minutes; the sown seeds are generally 1-3ppm and soaked for 5-10 minutes.
