Problems solved by technology

With this method, the seed potatoes produced in spring can break dormancy in time, so that they can be planted in autumn sowing with strong buds. At the same time, the problem of oversummer and high temperature storage of spring seed potatoes is solved, which is helpful for the production and management of autumn sowing potatoes

Embodiment 1

[0027] A cold storage method for accelerating germination of potato seed potatoes, comprising the steps of:

[0028] A. The seed potatoes produced in spring are harvested and placed in a cold storage at a temperature of 0-6°C;

[0029] B. After storing the seed potatoes in step A for 30-60 days, adjust the temperature of the cold storage to 9-15°C;

[0030] C. After the seed potatoes in step B are stored for 2-5 days, adjust the temperature of the cold storage to 18-25° C. and store for 30-50 days.

[0031] Among them, in step A, the seed potato was sown on February 16, 2012, and the "Zhongshu No. 3" virus-free seed potato harvested on June 1; In the bag; move into the warehouse on the day of receipt, the temperature of the warehouse in step A is controlled between 0-4°C, after 30 days of storage, the temperature of the cold storage in step A is adjusted to 9-13°C, and the temperature of the cold storage in step B is adjusted after 2 days of storage The temperature of the co...

Embodiment 2

[0033] Embodiment 2 is the same as Embodiment 1, the difference is:

[0034]In step A, the seed potato was sown on January 28, 2012 and harvested on May 26. The virus-free seed potato of "Five Ruita"; in step A, the seed potato was stored in a corrugated box with 25kg / box; The weight of the seed potatoes in step A is 20-40g / piece; it is moved into the warehouse on the day of receipt, and the temperature of the warehouse in step A is controlled between 2-6°C; after storage for 45 days, adjust the temperature of the cold storage in step A to 12-15°C ℃; after storing for another 3 days, the temperature of the cold storage in step B is adjusted to 20-25 ℃; after about 13 days, germination begins, after 22 days, the buds are all formed, after 30 days, the buds are strong, and the requirements for sowing are met. The cold storage in steps A, B, and C is a warehouse with refrigeration function.

Embodiment 3

[0036] Embodiment 3 is the same as Embodiment 1, the difference is:

[0037] In step A, the seed potato was sown on February 16, 2012 and harvested on June 1, "Donnong 303" virus-free seed potato; in step A, the seed potato was stored in a basket at 20kg / basket; Moved into the warehouse on the same day, the temperature of the warehouse in step A is controlled between 0-6°C; after 60 days of storage, the temperature of the cold storage in step A is adjusted to 12-15°C; after storage for 5 days, the temperature of the cold storage in step B is adjusted to 20-6°C 23°C; after about 12 days, the buds will start to sprout, after 35 days, the buds will be full, and after 45 days, the buds will grow strong, meeting the requirements for sowing. The cold storage in steps A, B, and C is a warehouse with refrigeration function.

Abstract

The invention relates to the technical field of crop seeds, and discloses a technology for refrigerated and accelerated germination of potato seed potatoes, comprising the following steps: A, the potato seed potatoes are harvested and placed in a cold storage at a temperature of 0-6°C; B, the seed potatoes in step A are stored After 30-60 days, adjust the temperature of the cold storage to 9-15°C; C, after storing the seed potatoes in step B for 2-5 days, adjust the temperature of the cold storage to 18-25°C, store for 30-50 days, and then sow in autumn. The present invention carries out the potato seed potato storage and germination at the same time, which not only solves the problem of oversummer storage of potato seed potatoes produced in spring, but also solves the problem of conflict between the dormant period of potato seed potatoes and the suitable sowing period of autumn sowing; Potatoes can be sown with strong buds at the suitable sowing time for autumn sowing, and germination is simple and reliable; the effect of refrigeration and germination of potato seed potatoes is not affected by the dormancy period of the variety, which is conducive to the promotion of new potato varieties of virus-free seed potatoes in autumn potato production.

Description

technical field [0001] The invention relates to the technical field of crop seeds, in particular to a method for refrigerating and accelerating germination of potato seed potatoes. Background technique [0002] Potatoes are traditionally planted in spring and autumn in the two-season cropping areas of the middle and lower reaches of the Yangtze River. Due to the high temperature in July to August, autumn potatoes are generally sown from the end of August to early September, and the seedlings emerge around September 20. They are harvested in early November and harvested in mid-November. If the temperature is too low in the future, the aboveground part will die easily. Therefore, the growth period of potatoes in autumn is shorter, and the suitable sowing period is only about 10 days from the end of August to the beginning of September, and the suitable sowing period is short. Under natural conditions, it takes at least 3 to 4 months for seed potatoes from harvest to sowing und...
