Method for producing seed potatoes

Abstract

The invention discloses a method for producing seed potatoes, which comprises steps: 1 tube seedlings which are lush in growth are selected to be as cutting seedlings; 2 vermiculite is fully soaked through water a day before cutting, then is filtered, and is arranged in a nursery seedling plate; 3 tube seedlings which are exercised indoor for 1-2 days, and the tube seedlings with 8-12 leaves are cut into segments according to leaf segments through ophthalmology scissors which are disinfected through ethyl alcohol; 4 the cutting seedlings are soaked through gibberellin and rooting power solution for 5-30 min, and the leaf segments are paved in a plate with a filter paper; 5 the lower ends of the leaf segments of the cutting seedlings which take roots are clamped through healthy ophthalmic forceps, and are lightly inserted into the vermiculite of the nursery seedling plate; and 6 the leaf segments of the cutting seedlings are gradually let in fresh air after being cut for 7-10 days, are watered with clear water after cutting, and are watered with appropriate nutrient solution after 5-7 days, thereby being capable of obtaining minituber seed potatoes after being cultivated for 40-60 days. The method for producing the seed potatoes has the advantages of is simple equipment, less labor, low cost, less seed usage, rapid breeding, high efficiency and convenient industrialized production and the like.

Description

technical field [0001] The invention relates to the technical field of potato production, in particular to a method for producing seed potatoes. Background technique [0002] At present, general growers use such as tip and axillary buds to root, and utilize branches, young shoots and cut sections of young shoots to propagate potato seedlings that can be used for planting. But at present, more research and development personnel have begun to conduct research on the technology of producing seed potatoes from potato seedlings. In the prior art: a method separates the shoot tip tissue cells of potatoes, cultures them in vitro in a nutrient, and then induces rooting, or induces the formation of miniature stems. The production method of the micro tuber is as follows: virus-free test-tube seedlings are cultivated in a nutrient-free medium, and the bottles for cultivating plants are numbered according to the plants. After about three weeks, the nutrient in the bottle must be repla...

Problems solved by technology

The disadvantages of this method are: long production cycle, 10-12 weeks for mini tubers and 85-90 days for small tubers

High cost: the production process is carried out in the laboratory, and a lot of organic matter is consumed, the cost is high, and the difficulty of production is increased
