Embodiment
The concrete enforcement of cultivation method main points of the present invention is as follows:
One, suits measures to local conditions, select breeding for use
According to regional condition, suit measures to local conditions to select for use high yield and high quality, cold-resistant, disease-resistant worm, strong, the wide adaptability of regeneration power, the middle round-grained rice of moderate growth duration, glutinous rice, middle rice with japonica rice and indica hybrid rice are done the perennial root rice, are the prerequisites of succeeing, and also are the key factors of stable high yield.Advance over 2 years, we prove that all works all can be done the perennial root rice at 140-145 days conventional round-grained rice, glutinous rice and middle rice with japonica rice the time of infertility in single evening in production practices.The region of no relief of low height above sea level can be with late ripe excellent 63, middle round-grained rice, the glutinous rice spent; In mountain area, the upper level of low height above sea level preferably select for use and make Dan Wanquan fertility 130-135 days assorted excellent rice, middle round-grained rice, glutinous rice and do the perennial root rice, excellent as river perfume (or spice), eight excellent No. 6, do the perennial root rice in No. 1, round-grained rice of Soviet Union, revive No. 2, round-grained rice, March three (Hainan is glutinous) etc.
Two, region and field are selected
In the many rice varieties (combination) of China, which is suitable to do the not complete investigation as yet of perennial root rice, investigate and introduce a fine variety and plant experimentally, demonstrate, and promptly makes the kind (combination) of perennial root rice and does not find out; That how the perennial root rice is carried out winter is anticorrosion, frost damage prevention is also lacked experience, in view of this, so present stage, carrying out the selection of its cultivated area and field was important key in order to ensure perennial root rice success high yield.Therefore, should be selected in low height above sea level (100 meters) the region of no relief and in mountain area, the upper level of low height above sea level (300-400 rice), and to select on the sunny side, the water source is arranged, row irrigation is convenient, the soil property fertility is better-than-average, the field that soil acidity or alkalinity is moderate is cultivated the perennial root rice and is advisable.
Three, anticorrosion, frost damage prevention
Preparation do the perennial root rice in, late rice, at first, strengthen its extermination of disease and insect pest, especially to note carrying out preventing and controlling such as later stage rice fulgorid, aleyrodid, leafhopper, banded sclerotial blight, stalk rot, be strictly on guard against that due to illness worm harm causes that rice stub, dead the rotting of rice root can not regenerate; Secondly, note frost in anti-winter, snow, freezing evil, guarantee the rice stub sleeping bud, resting bud and root survive, and once more, do the field of perennial root rice, and winter, spring, closure against grazing fowl poultry prevented to ravage rice stub, early gave birth in order to the next spring and sprouted.Anti-corrosion measure is except that the above-mentioned reinforcement extermination of disease and insect pest, and harvesting back rice stub preferably sprays one or more in the bactericide such as 70% thiophanate methyl, 65% fenaminosulf, green prosperous No. 1, green prosperous No. 2, and is anticorrosion with sterilization, sterilization.But the field is put in draining before the winter, keeps field soil moistening, in order to soil aeration, promotes rice root, rice stub to survive; Cold comes interim, irritate the deep water about 3 cun, with frost prevention, snow, freezing evil; Warm weather of the winter of frostless, snow, freezing evil can be irritated thin skin water or be irritated half cun shallow water, in order to ventilation, coordinates the soil water, gas, heat, shortly supports the root stake of living, and prevents the death of rice stub radical bud.This is a perennial root rice anticorrosion protection against cold and freezing conditions evil in winter, guarantees next spring early growth and quick tiller, captures the key and the important assurance of high yield.
Four, just stay the rice stub height
In, the harvested rice stub of late rice is to the next spring, goes through the 5 wheat harvesting period times of Winter-Spring, because of being subjected to the freeze injury of beating and tremble with fear of Exposure to Sunlight, wind, rain, the high-order bud of its rice stub is death all.Therefore, the perennial root rice can not utilize high-order bud, utilize its next bud sprouting and tiller into fringe, so stay stake highly to want suitably, needn't stay stake by height, generally stays high 10-13 centimetre of stake.Rice stub will cut flat, does not tiltedly cut, and cuts the back rice stub and is not stained with mud, and keeps off and steps on, in case it rots and promotion is emerged neatly.
Five, intertill in good time, fill the gaps with seedlings, apply fertilizers scientifically
The perennial root rice from the year before last, the rice stub of late rice is longer, its feature: the one, do not have basal dressing, the 2nd, spring sprout growth early.Therefore, intertillage is early in good time topdressed, fills the gaps with seedlings, is weighed fertile tap holder, is key measure and the important assurance that perennial root rice early growth and quick tiller is captured high yield.Promote fertilization compositions based on earth measurement, lack and the cultivation yield index according to the rich of the various nutriment in a fertilizer content of soil, accomplish farmyard manure and chemical fertilizer combination, nitrogen, phosphorus, potassium are reasonably combined, see kind, see ground, see seedling, see fertilizer, see day etc. that " five see " applies fertilizers scientifically.Grasp the fertilization principle of " tap holder, protect in the middle of tail, the control ", take preceding weight, in light, the balance fertilizing method that mends the back, to satisfy demand paddy rice each breeding time to nutrition; Fill the gaps with seedlings: promptly cannot not excavate longly the dead rice stub of seedling, fill the rice stub alive of long seedling; Nitrogen, phosphorus, the general proportioning of potassium are: 1: 0.4: 0.6-0.7, the ratio that goes out seed manure (basal plane fertilizer), tillering fertilizer, ear manuer, granulated fertilizer is 60: 25: 10: 5.Specifically: go out seed manure and carry out the intertillage first time at the beginning of the last ten-days period topdress in mid-March, mu is executed pure people's domestic animals manure 200-250 kilogram, carbonic hydroammonium 25-30 kilogram, superphosphate 20-25 kilogram, 5 kilograms in potassium chloride, short early growth and quick tiller; Tillering fertilizer carries out the intertillage second time in early April and topdresses, and mu is executed 20 kilograms of Nitrogen, Phosphorus and Potassium (nitrogen, phosphorus, potassium were than 16: 16: 16), 5 kilograms in urea, 6 kilograms in potassium chloride, short tillering; At the beginning of the last ten-days period, ear differentiation 1-2 is during the phase in mid-May for ear manuer, and mu is executed urea 3-5 kilogram, 4 kilograms in potassium chloride, and with short ear differentiation, anti-grain husk flower is degenerated, and strives big panicle many grains per panicle; Granulated fertilizer is in late June, and beginning fringe to full heading time sees the leaf look is drunk and execute, i.e. field fertilizer, Miao Wang, and what the leaf look dark green does not execute, and available multi-element leaf fertilizer carries out top dressing; Otherwise, fertilizer deficiency, the leaf look takes off light green will the executing of in good time not changeing, and mu is executed urea 2-3 kilogram, and with big fertile king, multi-element leaf fertilizer etc. carry out top dressing 2-3 time, to keep later stage leaf look normal, strengthen photosynthesis, prolong the canopy leaf life-span, anti-early ageing promotes solid fullly, and it is heavy to improve ripening rate and dry granular.
Six, science Guan Shui, put roasting field in good time
After intertillage is topdressed, emerge, shallow water is short emerged, tillered to irritate tillering stage.According to the principle of " seedling when not waiting, time to not waiting seedling ", see seedling, see ground, see day, see water source etc. " four see ", dig trenches to drain the water away, put roasting field moderately and at the right moment, with upper-controlling-lower-promoting, control later stage ineffective tillering, strong root is strengthened stalk, big fringe is urged in diseases prevention.No matter assorted excellent rice still is conventional rice to the perennial root rice, and the dense planting specification is grasped 26 * 25 centimetres, 27 * 20 centimetres and is advisable, about every mu of slotting 10257-12346 clump.When mu stem tiller number reaches the 160000 seedling left and right sides, carry out the roasting field of draining, put afterwards earlier and bake.Leave over for the first time light roastingly on the lenient side, roastingly shank occurs to the limit, field and split, pin has been stepped on footprint, rehydration when mud is not stained with pin (irritate and reveal Tu Shui); Naturally carry out the roasting field second time after falling to doing in 2-3 days after the rehydration, roasting have fine fisssure, limit, field large fracture to occur to bottom of trench, and there is gap in the field, and pin is stepped on no footprint, and the rice seedling stem is hard, and leaf is energetically straight and upright, rehydration when white root exposes.Carry out " five see " after the rehydration and execute and protect the short ear manuer of tiller once, mu is executed Nitrogen, Phosphorus and Potassium 3-4 kilogram, and adopts the method for irrigation and drainage combination, mu seedling numerical control built in 20-22 ten thousand.Should stop roasting field during 2 phases to ear differentiation.In a word, science Guan Shui grasps shallow water and urgees to emerge, tiller, and enough seedlings are put roasting field, and booting stage, shallow water intermittently replaced, and heading flowering period keeps shoaling layer, and being in the milk keeps dried wet to the maturing stage, based on wet, and the short strong stalk of root of strengthening, diseases prevention is prevented early ageing, is increased the grain weightening finish.
Seven, the sick Chinese caterpillar fungus bird of the integrated control plague of rats
Adhere to the policy of " relying mainly on prevention; integrated control ", with cultural control, the body-building cultivation is main, strengthens forecast of disease and pest, carries out the field monitoring, catch " four worms, three diseases ", be that the control of snout moth's larva, rice fulgorid, rice leafhopper, rice leaf roller, rice blast, banded sclerotial blight and leaf blight is attached most importance to, adopt efficient, low toxicity, wide spectrum, safe, lasting agricultural chemicals integrated control, sick worm was eliminated before just sending out the stage, endangering.As, mu is converted water 3000-6000 doubly with chlopyrifos abamectin emulsifiable concentrate 100 grams, adds 30% malicious thiophene 100 grams and converts water 1500-2000 times solution, adds sick upright 100 grams that clear off of rice again and converts water 800-1000 times solution, mu spray admixing medical solutions 60-75 kilogram, but the multiple rice pest of integrated control; Basal stem rot, bacterial stripe, bacterial leaf-blight can be converted the water 500-1000 control of doubly spraying with Thiodiazole-copper 20%SC 100 grams, or convert water 1000-1500 and doubly water at base portion and prevent and treat; On April, topdress in conjunction with secondary intertillage the middle ten days, mu is executed 10 kilograms of golden rice dragons, to reach the purpose of weeding fertilising; The bird evil adopts net to catch and the poison bait poisoning, and the plague of rats carries out " five is unified " with green prosperous rodenticide and kills mouse.By comprehensively preventing the disease Chinese caterpillar fungus bird plague of rats, grain loss is dropped to bottom line, guarantee good harvest.
Eight, optimum period harvesting, smart beating carefully received
The perennial root rice is longer heading stage, and the heading maturing stage is inconsistent, for last season turns round and look at following season, captures bumper harvests, and therefore, the perennial root rice can not be waited 100% harvesting when ripe, will gather in during the spike of rice yellow maturity of GPRS 85%, accomplishes suitable period harvest, smartly beats thin receipts.Biennial root ratoon rice cultivation method according to the present invention carries out the processing ratoon regenerating rice culture, and its output can reach: general per mu yield reaches about 505.2 kilograms, and the highest per mu yield reaches 572.8 kilograms.If did the perennial root rice last season, following season plantation rice transplanting rice, the per mu yield of two seasons can reach more than 900 kilograms, even ton-grain in the per mu yield.
