Embodiment

A kind of rice direct seeding high yield planting technology, by selecting improved seeds, use sufficient base manure, whole, the seed treatment of exempting to turn over, evenly sowing, chemical weed control, water-saving irrigation, diseases and pests controlling, gather in the crops a series of processes in good time and realize.

1, kind is selected:

Select the good-quality high-yield hybrid rice combination that good, the ripe phase of plant type is moderate, lodging resistance is strong.

2, use sufficient base manure, large Tagayasu Den is whole:

According to Formula fertilization by soil testing requirement, fertilizer accounts for the more than 30% of land for growing field crops total fertilization amount, nitrogen: phosphorus: potassium (N:P2O5:K2O) is generally 1:0.5:0.7.25 kilograms of the general mu of semilate rice sealing fertilizers, 10 kilograms, urea is made base fertilizer.Advocate multiple green manure in winter, improvement soil structure, increases soil fertility, or no-tillage fertilizing, front stubble railway carriage or compartment ditch is cleared up to the soaked field of after planting pouring water.

3, date of seeding determine, seed treatment

(1) sowing time: semilate rice date of seeding arrangement will note making heading flowering period to avoid the hot weather of late July to early August, generally to be advisable about May 10.

(2) seeding quantity: seeding quantity should be according to the germination rate of seed, broadcast the factor such as rear weather conditions considers, generally with 667m ²with planting 2 kilograms of left and right.

(3) seed treatment and vernalization: select fine day to bask seeds before broadcasting 2 days.Seed first soaks 8 hours with clear water, takes to soak less the mode presoaking and germinating revealing more, the vernalization after 1-2 days of soaking seed, and the broken chest of seed shows money or valuables one carries unintentionally and sends out after fork, spreads refining bud out.Before broadcasting, do to transplant spirit seed soaking well, be watered 10 kilograms with 10 milliliters of transplanting spirits, soak 10 jin of rice sprouts, soak 10 minutes, can improve rice sprout resistance and the boisterous ability of anti-low temperature overcast and rainy day, improve live planting percent, guarantee that rice direct-seeding produces successfully.

(4) type of seeding: bud paddy is dried refreshing, in order to broadcasting evenly.Before sowing, by " mixing happyly " seed dressing for bud paddy, can take food by protection against rodents sparrow.1. according to weather forecast, select after planting to have above fine weather sowing in 3 days.2. a point railway carriage or compartment is quantitatively sowed, uniform broadcasting.3. while sowing, should note following 3 points: the one, when wind is large, preferably do not broadcast, in order to avoid it is irregular to spread the grain mud that falls, increases and move the rare labour intensity of close benefit.The 2nd, within latter second day, rain heavily if broadcasted sowing, dewatering outlet should be made to par mouth, anti-heavy rain washes away.Heavy rain is put water immediately later and is dryly prevented that rice sprout is drowned.The 3rd, thin skin water or flat ditch-water on when sowing railway carriage or compartment face, fall dry naturally; Found seedling seedling stage taking dry as main, moisture management is short takes root, and avoids open fire and floods seedling, guarantees planting percent.Broadcast the rear available braiding sack that earth is housed and haul out railway carriage or compartment ditch, railway carriage or compartment is wide 1.5 meters.

4, evenly sowing:

Every mu of seeding quantity 1-1.5 kilogram, should be weighed in a point railway carriage or compartment when sowing, uniform broadcasting.After planting, as emerged inequality, move close benefit in the 5-6 leaf phase and dredge, guarantee full stand.

5, chemical weed control:

No-tillage field can spray after front stubble results gram removes old grass without track; The i.e. 3-5 days after planting of the vertical pin of bud paddy, it is moistening that railway carriage or compartment face keeps, and without ponding, every mu sprays 19.5% wetting powder millet straw and loses 200 grams and be watered 25-30 kilogram, 3-5 days rehydrations after spray; Also 3-10 days after planting, every mu of use 10% pyrazosulfuron wetting powder (grass go out star) is directly thrown and is executed (do not spray, do not mix soil) by (new water friend) 15 grams (3 pouches), but should there be 3-5 centimetre of water layer in field, can prevent and kill off the multiple weeds such as needle spikesedge herb, convexutricle sedge herb.

6, water-saving irrigation:

Keep after planting railway carriage or compartment face anhydrous be conducive to emerge and root system under prick, during 1.5-2.5 leaf, railway carriage or compartment face is filled with shallow water, accomplishes that railway carriage or compartment face has water at booting and heading stage, all the other periods, except dry field control tiller, keep railway carriage or compartment ditch-water continuous, railway carriage or compartment face is dry wet.When every mu of seedling number reaches 220,000, when every square metre of total seedling number reaches more than 300, start dry field.Regulate rainwater the time of infertility, do not fill with and do not arrange as far as possible.

7, science is topdressed:

The 2-3 leaf phase, every mu imposes 5 kilograms of do wean fertilizer of urea, and after dry field rehydration, every mu chases after 10 kilograms, potassium chloride, Qi Suihou sprays " grain grain is full " in conjunction with every mu of the extermination of disease and insect pest and improves plant lodging resistance, and extension function leaf longevity, prevents later stage early ageing, improve ripening rate, increase thousand kernel weight.

8, diseases and pests controlling

When sowing, can execute control insect pest in seedling stage by face, growing period, according to sick insect pest situation report, the good banded sclerotial blight of keypoint control, striped rice borer, three generations paddy stem borer, rice fulgorid and rice leaf roller.

Although technical scheme described in the invention is described in detail the present invention with reference to the above embodiments on specification; but; those of ordinary skill in the art is to be understood that; still can modify or be equal to replacement the present invention; and all do not depart from technical scheme and the improvement thereof of the spirit and scope of the present invention, within it all should be encompassed in protection scope of the present invention.
