Abstract
The invention relates to seedling growing technology of test-tube potatoes, in particular to a method for growing seedlings through an indoor cultivating support for detoxicated test-tube potatoes. The method mainly includes the steps of designing of a seedling growing tray, a cultivating substrate formula, a nutrient solution formula and seedling growing. The seedling growing step includes: a germinant detoxicated test-tube potato is sown on the tray, then the tray with the sown potato is placed on a sterilized semi-opened light-emitting diode (LED) lamp cultivating chamber cultivating support to be cultivated, lighting is conducted for 8 hours under the LED lamp of red and blue light with the light intensity as 2500-3500 lux, the ratio of red light to blue light is 6:4, and the temperature is kept at 25 DEG C. 15-20 days later after sowing, seedlings are pulled out from a holed plate, roots with the cultivating substrate are transplanted, and seedling growing of small-size test-tube potatoes is delayed appropriately according to specific conditions. By means of the indoor cultivating support tray seedling growing technology, the detoxicated test-tube potatoes can emerge seedlings fast and neatly, strong seedlings are cultivated, production cost of seed potatoes is reduced, seedling emergent rate is high, loss of the detoxicated test-tube potatoes is less, emergent rate can be more than 95%, transplanted seedlings are easy to survive, root damage is small, a device is simple and can be used repeatedly, and operation is convenient.
Description
Technical field
The present invention relates to the seedling growing process of test tube potato, the method that particularly the indoor culturing rack of a kind of potato detoxicating cuvette potato is grown seedlings.
Background technology
Potato is important grain, vegetables, feed and the raw material of industry, has that output is high, a strong adaptability, the characteristic such as nutritious, has become the fourth-largest cereal crops in the world.The application of virus-free seed potato technology is to solve the key that seed potato is degenerated, improved potato production benefit.Utilize tissue culture technique in laboratory, to produce the important breakthrough that detoxicating cuvette potato is virus-free seed potato production technology.In this technology, potato detoxicating cuvette potato survival rate of seedling is the key factor of restriction production efficiency, how to control rearing condition, for test tube potato provides the suitable condition of emerging, ensureing that test tube potato goes out shoot survival percent, is the technical issues that need to address in production practices.At present, the method that test tube potato breeding breeder's stock adopts is conventionally, live breeding in booth is bad due to moisture, nutrient, temperature control, often occurs being difficult for emerging, the problems such as irregular and weak seedling of emerging.In addition, " method of potato detoxicating cuvette potato float seedling " (application for a patent for invention number: 200710066315.6) improved the emergence rate of test tube potato, but need to build Miao Chi, cost is higher, is not suitable for growing seedlings on a large scale inconvenient operation.The method that the indoor culturing rack of test tube potato of the present invention is grown seedlings had both improved the emergence rate of test tube potato, can large-scale industrializedly produce again, simple to operate, and apparatus can reuse, with low cost.
Summary of the invention
The object of the invention is to propose the method that the indoor culturing rack of a kind of potato detoxicating cuvette potato is grown seedlings, on the basis of existing detoxicating cuvette potato seedling growing process, adopt indoor culturing rack tray seedling growth technology, the strict test tube potato seedling raising environment of accurately controlling, reach and make test tube potato fast, fitly emerge, cultivate strong sprout, reduce the production cost of potato seed.
For realizing above goal of the invention, the present invention proposes following technical scheme: the method that the indoor culturing rack of a kind of potato detoxicating cuvette potato is grown seedlings, is first seeded in the test tube potato of germination on the dish of cave by seeder; The cave dish of having sowed is put in chassis, and the dark nutrient solution of 1cm is injected on chassis, and nutrient solution slowly soaks culture matrix by sidewall immersion hole, bottom, hole; Then put on culturing room's culturing rack and cultivate, illumination every day 8 hours under the red blue LED lamp that is 2500-3500lux in light intensity, red blue light, than being 6:4, keeps 25 DEG C of temperature; In chassis, injected fresh nutrient solution every 4 days, injection rate is the half that starts injection rate, keeps liquid level in chassis, and unnecessary nutrient solution is discharged by spillway hole; Cultivate and obtain seedling after 15-20 days, water in chassis is outwelled, chassis left-hand thread is on seedling, after being transported to Greenhouse base, seedling is extracted from cave dish, root system is transplanted with matrix in the hole of accomplishing fluently in advance on Greenhouse nursery, suitably covers matrix, waters normal root water, a shady and cool week, the seedling of just can waking up cultivated.
Further, on the dish of described cave, be distributed with water injection hole and some holes of growing seedlings, on described chassis, be provided with spillway hole; Described seeder comprises seed board, mud guard not with holes, is distributed with some planting holes corresponding to the hole site of growing seedlings on the dish of cave on described seed board, and described seed board bottom is provided with kerve, is provided with the mud guard not with holes that can extract in described kerve; The size of planting hole is only held a test tube potato, to guarantee sowing 1 test tube potato in each hole of growing seedlings, the longitudinal section in the described hole of growing seedlings is inverted pyramid type, described bottom, the hole sidewall of growing seedlings is evenly distributed with little immersion hole, described little immersion hole allows nutrient solution to pass through, but matrix and root system are not easy by maybe not passing through.
Further, described cave dish is evenly distributed with the hole of growing seedlings that entrance is 2.0cm*2.0cm pros above, described in the hole hole depth of growing seedlings be 3.0cm, adjacent pitch of holes is 0.5cm; Described little immersion bore dia is 0.2mm; Chassis is long 62cm, wide 42cm, dark 3cm, is provided with two spillway holes apart from tray bottom 1cm depths.
The matrix of growing seedlings further, is that vermiculite and perlite mix by the weight ratio of 8:1.
Further, the concrete formula of the nutrient solution in described seedling-cultivating tray is:
Nitrate of lime 945mg/L, potassium nitrate 1500mg/L, ammonium nitrate 1601mg/L, potassium dihydrogen phosphate 300mg/L, magnesium sulfate 350mg/L, iron salt solutions 2.5ml/L, micro-5ml/L, pH=6.0;
Iron salt solutions: ferrous sulfate heptahydrate 2.78g, disodium ethylene diamine tetraacetate (EDTA.Na) 3.73g, distilled water 500ml, pH=5.5;
Liquid microelement: potassium iodide 0.83mg/l, boric acid 6.2mg/L, manganese sulphate 22.3mg/L, zinc sulphate 8.6mg/L, sodium molybdate 0.25mg/L, copper sulphate 0.025mg/L, cobalt chloride 0.025mg/L.
The present invention is better than other seedling-cultivating method specifically to be had: this method, emerge fast, and shorten the production cycle, only need now 15-20 days; This method emergence rate is high, and especially the most obvious for small size test tube potato effect, big or small potato emergence rate all can reach 85%, more much higher than booth direct seeding emergence rate; Transplant and easily survive, root system development is good, and when transplanting, root system damage is little; Facility is simple, can reuse, and after growing seedlings, culturing room can also use as culture test tube potato; Save nutrient solution, avoid pollute seedling stage.
