Abstract
The invention discloses a method for using sweet potato vines to reproduce sweet potato seedlings. The method includes the following steps: (1), cutting vines of harvested sweet potatoes which are strong and free of diseases into vine segments with at least 2 leaves, and placing the vine segments at a lucifugal and cool area until no liquid exists on vine sections for standby use; (2), subjecting the prepared vine segments to sterilization and rooting treatment, namely soaking the vine segments in carbendazim liquid for 3-5 minutes, taking out the vine segments, dripping away the carbendazim liquid on the surfaces of the vine segments, and soaking the vine segments in rooting liquid for 3-5 minutes; (3), inserting the vine segments soaked by the rooting liquid in a seedling bed in a greenhouse; (4), seedling cultivation management including a rooting and leafing period, a dormancy period and a growing period, wherein requirements on temperature and soil humidity are different in different periods. The method is used for cultivating the sweet potato seedlings.
Description
Technical field:
The present invention relates to seedling growing process, particularly a kind of method of Sweet potato stem breeding sweet potato seedling.
Background technology:
Sweet potato is comparatively strong to the adaptability of soil, liquid manure, and output is high, is widely cultivated in the region of irrigation conditions difference.The breeding of sweet potato is with the breeding of potato block, is placed on hotbed, burns hotbed degree and humidity that coal keeps hotbed below traditional hotbed by potato block, its temperature requirement is stricter, slightly carelessness can cause potato block to rot, and this traditional propagation method need consume potato block, and seedling cost is higher.
Summary of the invention:
The present invention seeks to the method for a kind of Sweet potato stem breeding sweet potato seedling obtaining potato seedling without sweet potato soon.
The technical scheme realizing the object of the invention is, a kind of method of Sweet potato stem breeding sweet potato seedling, it is characterized in that there are following steps: (1), climing after sweet potato rewarding disease-free for stalwartness is cut into climing section that is no less than 2 blades, lucifuge is cool puts climing section without till juice, for subsequent use;
(2), by above-mentioned ready climing section carry out sterilizing and rooting treatment: first climing section is placed in carbendazol and soaks 3-5 second, take out and after the carbendazol pouring on climing section surface is fallen, make climing section in taking root liquid, soak 3-5 second;
(3), above-mentioned climing section of soaking taking root liquid is inserted in the seedbed in booth;
(4), the management of nursery is divided into the phase of coming into leaves of taking root, resting stage and vegetative period,
Taking root the management of the phase of coming into leaves: the temperature of the phase of coming into leaves of taking root of climing section of sweet potato is 15-20 DEG C, and soil moisture is 50-60%, makes climing section to take root very soon, and grows new blade gradually, when growing the new blade of 4-6 sheet, seedling being stopped growing,
The management of the resting stage of sweet potato's seedlings: temperature is 9-14 DEG C, soil moisture at 30-40%, and keeps good illumination, prevents seedling wind long,
The management in the vegetative period before emerging, before potato transplantation of seedlings to the earth, make the sweet potato's seedlings restoration ecosystem of dormancy, temperature remains on 15-25 DEG C, and soil moisture is 50-60%, keep good illumination, in this vegetative period, the petiole director of the new blade of potato seedling goes out sprouting, when sprouting grows 4-6 blade, sweet potato seedling on seedbed is pulled out, the sprouting on seedling is cut off and tumbles on land for growing field crops.
The present invention has compared with the prior art and does not consume sweet potato and the remarkable advantage of breeding potato seedling.
Embodiment:
Traditional sweet potato nursery is all on hotbed, carry out nursery with potato block, needs to consume a large amount of potato blocks, and this method does not change so far.
In order to solve the defect of the consumption potato block utilizing potato block breeding and seedling to exist, through repeatedly testing, successfully achieving and utilizing the climing incubation potato of stem when gathering in the crops sweet potato autumn seedling, for sweet potato nursery have found a kind of new method.
This seedling-cultivating method is:
1, select healthy and strong disease-free sweet potato climing, be cut into climing section by climing by 3-5 leaf, lucifuge is cool puts two hours to the potato liquid on the end face of potato section solidifies, generally needs for subsequent use;
2, above-mentioned ready sweet potato climing section of elder generation is taken out after many mattresses ichor soaks the several seconds, after drenching the many mattresses ichor on clean climing surface, again 1-2 second is soaked in the termination of climing section in taking root liquid;
3, climing section after above-mentioned immersion taking root liquid is tumbled on seedbed; The requirement of nursery soil, because to soil and liquid manure, sweet potato requires that not tight, nursery soil requires that soil layer loosens, draining is good, containing certain organic fertilizer;
4, seedling management be divided into the phase of coming into leaves of taking root, resting stage and vegetative period three phases.Due to nursery stage in the sweet potato rewarding phase (Frost's Descent is forward and backward) to the beginning of April next year, have cold winter therebetween, the temperature and humidity of seedbed and growing environment has different requirements.
Taking root the linear leaf phase: require that temperature is 15-20 DEG C, soil moisture is 45-55%, when growing new blade 5-6 sheet, it should be made to stop growing.
Resting stage: temperature requirement, but can not lower than 9 DEG C lower than 15 DEG C, and soil moisture is 30-40%, prevents seedling frostbite, makes seedling enter resting stage, prevents wind long.
Vegetative period: the seedling of resting stage should be made to proceed to vegetative period planting (generally in the last ten-days period in February) before seedling stage to land for growing field crops, temperature is 15-25 DEG C therebetween, soil moisture is 50-60%, and add intense light irradiation, make seedling healthy and strong, make seedling go out sprouting the petiole director of the blade newly grown, and sprouting grows 4-6 blade to land for growing field crops be applicable to plant potato seedling time, extract seedling by seedling sprouting be separated be inserted in land for growing field crops.
In order to the condition of the temperature and soil moisture that meet above-mentioned nursery, seedbed should be built in booth.
