Description
Technical field
The invention belongs to tobacco seedling technical field, be specifically related to the floating outstanding alternate cycles seedling-cultivating method that grows tobacco.
Background technology
At present, 1,800 ten thousand mu of cigarette areas are planted throughout the year by China, and the seedling raising manners overwhelming majority is floating seedlings and moistening seedling raising manners.Floating seedlings mode is the seedling-cultivating tray of making of polystyrene, and interior filling substrate, swims on nutrition liquid level and grow seedlings, and is characterized in that tobacco seedling growth is neat, and cost is lower, is convenient to management, is beneficial to batch production, large-scale production.Therefore, this technology is introduced after China from the nineties, perfect by digesting and assimilating and innovating, and in China's tobacco business development rapidly, has just exceeded 90% of the gross area at usable floor area in 2009.But along with the expansion of area, the defect of itself also obviously shows.Because cigarette shoot root is that long term growth approaches in saturated environment at moisture, the nutrient solution water surface and air partition make it melt hypoxgia, cause improving activity of root system to weaken, and return the seedling time long after cigarette transplantation of seedlings, as it is easily dead to run into xeothermic weather.Due to these defects of floating seedlings, tobacco scientific worker, in conjunction with traditional earth culture seedling raising manners of past, has worked out again moistening seedling raising manners, is specially: adopt the floating mode of shallow water in the early stage of growing seedlings, utilize and manually carry out discontinuity water spray in the middle and later periods.Due to discontinuity water spray, make root system be in the environment of alternation of wetting and drying, the further growth of induction root system is grown, and therefore adopts the method tobacco root of growing seedlings to grow than floating seedlings root system, goes back the seedling time to shorten dramatically after transplanting.Therefore, moistening grow seedlings and gradually promote come.But because moistening growing seedlings will rely on a large amount of artificial water sprays, cost is higher, and management inconvenience makes to promote the restriction of receiving again to a certain degree.
Summary of the invention
For overcoming prior art deficiency, the object of the invention is to provide the floating outstanding alternate cycles seedling-cultivating method that grows tobacco, and adopts the method to grow seedlings, tobacco seedling well developed root system, and cigarette seedling strong stress resistance after transplanting, does not have seedling-slowing stage substantially.
For achieving the above object, the present invention has taked following technical scheme:
One grows tobacco floats outstanding alternate cycles seedling-cultivating method, it adopts the mode of floating seedlings to grow seedlings filling in standoff nursery pond in advance, in the time that cigarette seedling grows 3-5 sheet true leaf, discharging part water in nursery pond makes seedling-cultivating tray be suspended on support and seedling-cultivating tray bottom keeps the height of 2-3cm to carry out suspension with the water surface growing seedlings, in interval 1-3 days backward nursery ponds, pass into water and carry out floating seedlings, again within interval 1-3 days, discharge afterwards part water in nursery pond and carry out suspension and grow seedlings, so alternate cycles is carried out floating and suspension and is grown seedlings; Treat that cigarette seedling grows the 8-9 sheet true leaf rear suspension 2-3 days that grows seedlings, and then transplants; Wherein, the water in described nursery pond is to contain the fertile aqueous solution of growing seedlings (being nutrient solution).
Concrete, the floating outstanding alternate cycles seedling-cultivating method of above-mentioned tobacco, comprises the steps:
1) be arranged side by side three identical nursery pond A, B and C, lay one deck antiseepage film at the bottom of pond, then in antiseepage film, place the fragment of brick of high 5cm as support, the placement density of fragment of brick is lived seedling-cultivating tray with energy suspension and is as the criterion;
2) in three nursery ponds, discharge water, seedling-cultivating tray is placed on simultaneously and on support, carries out floating seedlings;
3) in the time that cigarette seedling grows 4 true leaves, part water in nursery pond B and C is evacuated in nursery pond A with pump, so that the seedling-cultivating tray in nursery pond B and C is suspended on support and seedling-cultivating tray bottom keeps the height of 2-3cm to carry out suspension with the water surface growing seedlings (now the height of water level in nursery pond B and C just remains on 2-3cm), proceed floating seedlings in nursery pond A;
4) interval, after 1 day, pumps into the part water in nursery pond A in the B of pond, ensures that nursery pond B carries out floating seedlings, is that suspension is grown seedlings and nursery pond A and C carry out;
5) interval, after 1 day, pumps into the part water in nursery pond B in nursery pond C, ensures that nursery pond C carries out floating seedlings, is that suspension is grown seedlings and nursery pond A and B carry out;
6) interval is after 1 day, then the part water in nursery pond C is pumped in nursery pond A, ensures that nursery pond A carries out floating seedlings, is that suspension is grown seedlings and nursery pond B and C carry out; So alternate cycles is carried out, and after cigarette seedling grows 8-9 sheet true leaf, the equal suspension of nursery pond A, B and the C 2-3 days that grows seedlings, then transplants.
Above-mentioned three ponds, tobacco seedling pond share the amount of a conventional Chi Shui, grow seedlings that early stage, every Chi Shui was constant 1/3rd, at the bottom of pond, establish support.Utilize water pump at interval of the regular hour in the middle and later periods of growing seedlings, alternately a certain Chi Shui is discharged in another pond, the floating floating seedlings that carries out of seedling-cultivating tray that Chi Shui is many, two other pond seedling-cultivating trays are suspended on support and keep the height of 2-3cm to carry out suspension with the water surface and grow seedlings, and so form the alternate cycles of alternately floating outstanding and Chi Shui of seedling-cultivating tray.Realize the interruption supply of moisture, increase in water and melt oxygen, control water supply in media, form whole of air and drought stress environment, promote the further growth of root system.By this new mode, realize that seedling is strong, cigarette seedling strong stress resistance and save labour and reduce seedling cost after well developed root system, transplanting.Attention: if Chi Zhongshui reduces, while can not meet the seedling-cultivating tray floating state in a pond wherein, should suitably keep the skin wet.
