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
The present invention relates to a kind of potato production technical field, specifically refer to a kind of production method of seed potato.
Background technology
At present, general plantation family uses such as taper and axillalry bud to carry out root of hair, utilizes the segment etc. of branch, young shoot and young shoot to breed to can be used for the potato seed of planting.But the technology having more research staff to start to produce potato seed potato seed at present launches research.In prior art: a kind of method is separated the seedling point histocyte of potato, culture in vitro in nutritional agents, then root induction, or induces miniature stem block to be formed.The production method of its microtubers is: not containing the test-tube plantlet of virus, is not cultivating containing in nutritional agents, cultivates the bottle of plant by plant numbering.After about three weeks, the agent of bottle Middle nutrition must be changed with another kind of nutritional agents, to promote the synthesis of tuber character element.Cultivate 10 ~ 12 weeks under 17 DEG C of 1000 Lei, can grow 40 ~ 60 diameters is the microtubers of 0.3 ~ 0.6cm.The production method of tubercle is: aforementioned microtubers to be inserted kind or plantation containing 0.5kg/m
3the peat of urea artificial manure and perlitic composite soil.And need water to plant under natural temperature and illumination condition, to meet their needs.After eight weeks, growth regulator must be used to stop foliage development, and stop watering.After planting can obtain 3 ~ 4 tubercle original seeds.The deficiency that the method exists is: the production cycle is long, and micro potato needs 10 ~ 12 weeks, and tubercle needs 85 ~ 90 days.Cost is high: production process is all carried out in laboratory, and will exhaust many organic matters, and cost is high, increases the difficulty of producing.
