Abstract
The invention discloses a high-yield rice cultivation method. The method comprises the steps of improved variety selection, rational combination, sowing quantity increment, timely seedling sowing, cultivation and seedling strengthening, rice seedling field management, base seedling increment, early cultivation at appropriate age, suitable close planting, formula fertilization, scientific water management, and disease and pest prevention and control. The defect that the rice yield is lower due to the weak double cropping rice producing area season awareness, the poor rice seedling quality, the lower density, the insufficient absolute plants and the like is overcome. According to the high-yield rice cultivation method, every mu of the field is sown with seedlings larger than seedlings sown in the prior art by a half kilo, the density of the seedlings is increased by two to three times, the seedlings cultivated through the high-yield rice cultivation method are 5000-6000 larger than the seedlings cultivated in the prior art, the application amount of base base-tiller nitrogen fertilizer is decreased, the application amount of granule fertilizer is increased, water is controlled by the water-gas balance, and plant diseases and insect pests are prevented so that the percentage of earbearing tiller can be improved; the absolute plants can be increased by 30000 to 40000, the yield of grain produced through the high-yield rice cultivation method is a hundred larger than that of grain produced in the prior art, and the purpose that the rice per unit area yield is greatly improved is achieved.
Description
Technical field
The invention belongs to plant cultivation grain management method class, relate to a kind of rice high yield method.
Background technology
Tradition double cropping rice producing region consciousness in season is weak, seedling quality is poor, density is on the low side, effective fringe is not enough, causes rice yield lower.
Summary of the invention
In order to overcome, double cropping rice producing region consciousness in season is weak, seedling quality is poor, density is on the low side, effective fringe is not enough, cause the shortcoming that rice yield is lower, a kind of high yielding culture of rice method takes every mu of multicast one jin of kind, increase by 2 ~ 3 one-tenth density, many cultivation 5 ~ 6,000 root and stem of certain plants seedlings, subtract and execute base fetilizer for tillering, enrich fringe granulated fertilizer, aqueous vapor balance pipe water, the measures such as anti-good damage by disease and insect, to reach the raising percentage of earbearing tiller, increase by 3 ~ 4 universal effect fringes, fecund hundred jin of paddy, realize the target increasing substantially paddy rice yield per unit area, thus make increasing production of rice, increase food supply.
The technical scheme that the present invention takes is:
Select breeding, reasonably combined.Select high yield, high-quality, multi-resistant rice kind, as excellent in Y two No. 1, the super hybridization rice kind such as excellent No. 1 of middle Zhejiang, or other hybrid rice improved seeds, as inner excellent 6602, rich excellent 782 etc.Adopt " taking late late " or " in taking late "
Increase sowing quantity.Hybrid rice mu sowing quantity, by current 0.75 ~ 1 kilogram, brings up to 1.25 ~ 1.5 kilograms; Conventional Rice mu kind amount, by current 1.55 ~ 2.0 kilograms, brings up to 2.25 ~ 2.5 kilograms.
Begin sowing in good time.Early rice is in late Febuary to early March, and late rice to the middle ten days, is no more than sowing on July 15 in early July at the latest.
Cultivate strong seedling.One is mould plate seedling raising: apply 434 holes and mould dish, 60 ~ 65, every mu, early rice, late rice 65 ~ 70.With seedling strengthen agent or Fertilizer special for raising rice seedlings seedling, half is spread fertilizer over the fields on seedling bed, and second half dispenser is moulding in disk hole cave.Evenly during sowing broadcast light seeding, 2, the every cave of hybrid rice, conventional Rice 3, every cave seed.Two is the seedling of woven cloth interlayer: use sufficient well-rotted farmyard manure during whole ground or drench sufficient liquid dung, or every square metre of rice seedling bed sealing fertilizer 50 ~ 80 grams.After woven cloth tension is paved, spread fertile mud or mud that thickness is 2 cm, weed and loosen the soil with paddy-field harrow flat, then the seed through " dry-raised nurse " dressing is evenly spread, broadcast conventional Rice 80 ~ 100 grams for every square metre, hybrid rice 50 ~ 60 grams, after planting pressing-seed-into-mud or by fine earth lid kind.
Young plants management.Early rice after planting covers warming with plastic sheeting for farm use, and late rice after planting covers sun-proof rainproof with covering; Note ventilation hardening, water in right amount and weed a garden; As not enough in base fertilizer, rice shoot two leaf wholeheartedly time to drench with loose stool water or methane liquid or 1% ~ 2% urea solution and execute after, then wash seedling with clear water; Transplant to execute to send for first 5 ~ 7 days and transfer fertilizer, drench with loose stool water or methane liquid or 1% ~ 2% urea solution and execute.
Increase base seedling, of the right age morning plants, rational close planted.Early rice transplants 20 ~ 25 days length of time rice seedlings grow, leaf age 3.5 ~ 4.0 leaf; Late rice transplants about the 15 days length of time rice seedlings grow, leaf age 4.0 ~ 5.0 leaf.Hybrid rice seed density in planting every mu 1.8 ~ 2.2 ten thousand root and stem of certain plants, conventional Rice planting density every mu 2.0 ~ 2.3 ten thousand root and stem of certain plants.
Rational application of fertilizers.Total fertilization amount (chemical fertilizer nutrient scale): N10 ~ 11 kilogram, P205 5 ~ 7 kilograms, K20 10 ~ 14 kilograms.
Base manure: mu applications of farmyard manure 750 ~ 1000 kilograms, 30 kilograms, urea, 35 ~ 45 kilograms, fused calcium magnesium phosphate, 7 ~ 10 kilograms, potassium chloride, or other chemical fertilizer that nutrient content is equal; Tillering fertilizer: transplant latter 5 ~ 7 days, mu executes 6 ~ 8 kilograms, urea, 4 ~ 5 kilograms, potassium chloride; Ear manuer: after the backwater jointing of open field, mu executes 6 ~ 8 kilograms, urea, 6 ~ 8 kilograms, potassium chloride; Granulated fertilizer: cut heading stage, the light mu of leaf colour cast executes 2 ~ 3 kilograms, urea, green not the executing of leaf colour cast; Top dressing: after neat fringe, 0.2 kilogram, mu phosphoric acid the second light industry bureau potassium adds 0.5 kilogram, urea and converts 50 kilograms, clear water and spray.
Science Guan Shui.Surrounding drain ditch and work ditch is held successfully before rice transplanting.Surrounding drain ditch requires furrow width 30 centimetres, opens a work ditch, furrow width 30 centimetres, ditch depth 15 ~ 20 centimetres by 4 ~ 6 meters.Aqueous vapor balance science Guan Shui: moistening rice transplanting, moistening or thin moisture tiller, reveals dry field control seedling when mu has seedling number to reach 15 ~ 160,000, and many dew is light to be shone; Ear differentiation, Filling stage, based on moistening irrigation, utilize natural precipitation or artificial furrow irrigation moisturizing to keep face, railway carriage or compartment moistening; Naturally fall stage of yellow ripeness water in hondo, avoids face, field dry and cracked too early.
Sick worm prevention and control.One is transplant to execute to send for first 3 ~ 5 days to transfer medicine, prevention snout moth's larva, rice blast, south rice dwarf wilt etc.; Two is transplant latter 5 ~ 7 days, uses the weeding of this field herbicidal in conjunction with fertilising; Three are cut heading initial stages prevent and treat snout moth's larva, rice blast, rice fulgorid, false smut attach most importance to, mixed reagent guarantor fringe; Four is in the Control stage of forecast, by index for control, selects efficient, low toxicity, counterpart pesticide control, keypoint control paddy rice " two move " insect; Five is that the sick worm of the green prevention and control technology prevention and control such as frequency ventilating type insecticidal lamp, gyplure, biopesticide is promoted in place with good conditionsi.
