Abstract
The invention discloses a seedling raising method for colored rice. The method comprises the steps: (1) mounting a bracket capable of rising and falling in a seedling raising pond, arranging three seeding nurseries on the bracket, separately placing colored rice seeds, i.e., purple-leaf rice, golden rice and purple-ear rice into different seeding nurseries, storing a nutrient solution in the seedling raising pond, and carrying out seedling raising by adopting a floatation seedling nursing manner in advance until each colored rice seedling grows out 1-4 true leaves; (2) rising the bracket to enable bottoms of the three seeding nurseries to keep the height of 1-4cm from the water surface of the nutrient solution, and carrying out suspension seedling raising for 1-3 days; (3) lowering the bracket to enable the three seeding nurseries to be submerged into the nutrient solution, and carrying out floatation seedling nursing for 1-3 days; and (4) repeating the steps (2 and 3) until each colored rice seedling grows out 6-10 true leaves, then, carrying out suspension raising seedling for 1-5 days, and then, carrying out transplanting. By the novel manner, the effects that the seedlings are robust, the root systems are developed, the resistance of the colored rice seedlings after transplanting is high, labor is saved, and the seedling raising cost is reduced are achieved.
Description
Technical field
The invention belongs to Rice Cropping technical field, be specifically related to the seedling-cultivating method of a kind of colored paddy rice.
Background technology
Breeding scholar can cultivate some form colors when cultivating rice varieties and conventional rice difference is larger, but the rice varieties that quality taste difference is little, such different shape color especially different colours rice varieties collocation get up, the pattern of different colours can be formed in field, this progressively becomes a unique earth art for 2 years, possesses very high sight.Meanwhile, along with sightseeing and tour agriculture day by day rises, this behavior is excavated by people in the past two years gradually, utilizes, and will inevitably come in more location popularization, becomes various places sightseeing tour sight spot.And along with the popularization of this colored Rice Cropping earth art, pattern will inevitably become increasingly complex.
Paddy rice is one of topmost cereal crops in the world, it is again kind more excellent in paddy, existing paddy rice has engendered colored paddy rice, the paddy rice that color is different can be planted out, various character and graphics is formed in field, play the effect of viewing and admiring, simultaneously also can as grain, following problem has been there is: 1 in existing colored Rice Cropping process, Plant Height of Rice is inadequate, can not sight not high, 2, in planting process, chemical fertilizer consumption amount is very big, substantially increase planting cost, 3, run into insect pest and often use pesticide spraying deinsectization, paddy color can be affected, and it is edible unhealthy.
Because color water rice seedling root system long term growth is in the environment of water saturation, the nutrient solution water surface and air partition make it melt hypoxgia, cause improving activity of root system to weaken, and it is long that color water rice seedling returns the seedling time after transplanting, as easily dead in run into dry weather.Due to these defects of floating seedlings, investigated again moistening seedling raising manners, be specially: adopt shallow water floating mode early stage in nursery, utilize in the middle and later periods and manually carry out discontinuity water spray.Due to discontinuity water spray, make root system be in the environment of alternation of wetting and drying, induction root system further growth is grown, and therefore adopts the colored rice root of the method nursery to grow than floating seedlings root system, goes back the seedling time to shorten dramatically after transplanting.Therefore, moistening nursery is promoted gradually again and is come.But because moistening nursery will rely on a large amount of artificial water spray, Cheng Mu is higher, and management inconvenience, makes to promote and receive restriction to a certain degree.
Summary of the invention
Object of the present invention takes notice of the seedling-cultivating method providing a kind of colored paddy rice, solves the technical problem that colored rice root in prior art is undeveloped, transplant resistance.
In order to solve this technical problem, the present invention adopts following technical scheme:
A seedling-cultivating method for colored paddy rice, comprises the following steps:
Step one, the support that installation can be elevated in nursery pond, support is provided with three nurseries, purple for color water rice leaf rice, golden rice, purple fringe rice are placed in different nurseries respectively, nutrient solution is contained in nursery pond, the mode of floating seedlings is adopted to carry out nursery in advance, when color water rice seedling grows 1-4 sheet true leaf;
Step 2, lifting support make all to keep the height of 1-4cm to carry out suspension nursery bottom three nurseries with the nutrient solution water surface, and suspension seedling raise period is 1-3 days;
Step 3, reduction support make three nurseries all immerse in nutrient solution, and carry out floating seedlings, the floating seedlings time is 1-3 days;
Step 4, repetition step 2, three, alternate cycles like this carries out floating and suspension nursery; Treat that color water rice seedling grows 6-10 sheet true leaf rear suspension nursery 1-5 days, then transplant.
Further improvement, the seedling-cultivating method of colored paddy rice, comprise the following steps: step one, the support that installation can be elevated in nursery pond, support is provided with three nurseries, purple for color water rice leaf rice, golden rice, purple fringe rice are placed in different nurseries respectively, contain nutrient solution in nursery pond, adopt the mode of floating seedlings to carry out nursery in advance, when color water rice seedling grows 2 true leaves;
Step 2, lifting support make all to keep the height of 3cm to carry out suspension nursery bottom three nurseries with the nutrient solution water surface, and suspension seedling raise period is 2 days;
Step 3, reduction support make three nurseries all immerse in nutrient solution, and carry out floating seedlings, the floating seedlings time is 2 days;
Step 4, repetition step 2, three, alternate cycles like this carries out floating and suspension nursery; Treat that color water rice seedling grows 7 true leaf rear suspension nursery 3 days, then transplant.
Further improvement, lays one deck antiseepage film at the bottom of described nursery pond, control nutrient solution seepage.
Further improvement, contain nutrient solution nutrient solution in described nursery pond and be made up of macroelement, trace element, molysite, macroelement is: ammonium nitrate, potassium nitrate, calcium chloride, magnesium sulfate, nitrate of lime, potassium dihydrogen phosphate; Trace element is: manganese sulphate, zinc sulphate, copper sulphate, ammonium molybdate, boric acid; Molysite is: ferrisodium salt.
Further improvement, weighs macroelement, trace element, molysite by 20 times and 200 times of commercial weight, is made into concentrate, when using, adds macroelement 50ml in every premium on currency, micro-5mL at every turn, and fully make nutrient solution after mixing, PH is adjusted to 5-7.
Alternately float alternate cycles that is outstanding and Chi Shui, realize the interruption supply of moisture, increase in water and melt oxygen, control water supply in media, formation air quality grade and thousand early stressful environmental, promotes the further growth of root system.By this new mode, realize that seedling is strong, well developed root system, color water rice seedling strong stress resistance and save labour and reduce seedling cost after transplanting.
Compared with traditional floating seedlings mode, beneficial effect of the present invention has as follows:
1, seedling-cultivating method color water rice seedling root growth environment of the present invention has greatly improved, the long increase by more than 30% of total root, and total root volume increases by more than 30%, and rhizome dry weight is than improve more than 30%.
