The invention provides the single cropping rice high-yield cultivation method, the rice is sufficient in ears, large in ears, heavy in grains, and the method is high in yield. The single cropping rice cultivation method is characterized by comprising the following steps: 1, selecting a variety, sowing early in good time, including selecting the variety which is good in adaptability, large in ears, more in grains, and high in yield, and is fertilizer tolerant and lodging resistant, and has excellent yielding ability; 2, performing fertilizer and pesticide seed dressing and mulched adaptability, with each 500 g seeds in a 30 m<2> seedbed as standard, preferably performing seedbed unified seedling raising in a centralized manner, before sowing, firstly cleaning seeds which are soaked and disinfected; 3, raising middle age seedlings in a dried manner, and transplanting rice seedlings in shallow water, seedling age increasing to about 25-28 days, transplanting the rice seedlings when leaf age is about five leaves, having 2-3 tillers, inserting double seedlings; 4, performing double seedling thin planting, and wide narrow row alternate planting, originally planting 6 rows in each width by manual transplantation of each person being changed into four rows of wide and narrow row spacing , 40 cm for a wide row and 20 cm for a narrow row, average row spacing being about 30 cm, spacing in the rows being 22 cm, and cluster number in each mu being about ten thousand.
Description
Technical field
the invention belongs to planting technology field, particularly relate to the culture technique of a kind of single cropping rice.
Background technology
paddy rice originates in Tropical Asian, after China widely plants, propagates into gradually all over the world.According to diverse ways, paddy rice can be divided into long-grained nonglutinous rice and japonica rice, early rice and middle late rice, glutinous rice and non-glutinous rice.The research of China scientist Yuan Longping to hybrid rice makes a great contribution, and is described as " father of hybrid rice ".The grain of rice that paddy rice is tied claims rice, scented rice, rice or rice after shelling.Nearly half population is in the world all food with rice.The eating method of rice is varied, has rice, congee, rice cake, rice cake, rice noodles rice wine etc.Paddy rice, except edible, can also be made wine, refine sugar and make the raw material of industry, rice husk, rice straw, can as feed.China paddy rice main producing region mainly the Northeast, the Yangtze river basin, Pearl River Delta.Paddy rice institute knot reality and paddy, claim rice or rice after shelling.Belong to direct economy crop.Still the staple food of 1/3rd mankind in the world.Rice precision determined amounts culture technique, according to different soil, kind and design output, in the strong seedling of cultivation, culturable standard, fertilization mode and water management etc., carrying out accurate quantification, and by quantitatively operating, is perfect further to rice intensification technology and rational application of fertilizers technology.In conjunction with actual conditions and the late high-yield culturing experience of our station list in the past of Dongyang City, adopt the cultivation strategy in " early stage Hong, control in mid-term, the later stage attacks ", namely " urge in earlier stage early to send out to strive large tiller; control colony in mid-term strives into fringe; fringe type of assaulting the main target and grain weight ", thus reach the object that fringe is sufficient, fringe is large, grain is heavy, output is high.
Summary of the invention
the present invention is exactly for the problems referred to above, provides a kind of fringe foot, a kind of single cropping rice high-yield cultivating method that fringe is large, grain is heavy, output is high.
to achieve these goals, the present invention adopts following technical scheme.
a kind of single cropping rice high-yield cultivating method, is characterized in that: comprise the following steps.
one, kind is chosen, in good time early sowing; " selection adaptation is good, fertilizer resistance anti-lodging, big panicle many grains per panicle output are high, has the kind of extremely strong yielding ability.The determination in sowing time, meets the weakness of Yu Yifa false smut according to the excellent series of products full heading time in river in Zhejiang Province.
two, the seed dressing of medicine fertilizer, drought educates strong seedling by every 500g seed 30m2 seedbed standard, concentrate and carry out seedbed and unify seedling, before sowing, first the seed through seed soaking sterilization is cleaned, drench fenaminosulf liquid, and mix Imidacloprid 15g by every 600g seed, fused calcium magnesium phosphate 200g standard is dressed seed, broadcast rear earthing 1cm, fill with half ditch-water and let alone auto drying, make furrow face moistening, second afternoon is unified sprays furrow face management of weeds with 500 times of butachlor liquids, non-irrigated seedling is cultivated in the seed dressing of medicine fertilizer, can endanger by basic controlling rice shoot sick worm in early stage, make well developed root system, rice shoot is healthy and strong, without falling yellow phenomenon after rice transplanting, growth is fast, tiller early many, for large tiller Cheng great Sui lays a good foundation.
three, drought educates middle seedling, the shallow water rice transplanting length of time rice seedlings grow is increased to about 25 ~ 28 days, the left and right rice transplanting of leaf age 5 leaf, and band tiller 2 ~ 3, two basis is inserted.Rice transplanting to be executed rake leaven the previous day and is weeded and loosen the soil flat field, and the same day was first arranged the rice transplanting again of shallow Soil surface water layer in rice transplanting, filled with thin water after 3 days.Shallow water rice transplanting, can avoid on the one hand floating seedling to lack clump, accelerate to take root growth, is conducive on the other hand shallowly inserting, early tillers, becomes large tiller, within after rice transplanting about 20 days, just can send out the sufficient seedling number corresponding to number of productive ear.
four, in original rice transplantation by hand, everyone often plants a width is that 6 row replant as width line 4 row for this thin planting two, wide-narrow row planting, wide row 40cm, narrow row 20cm, average row apart from about 30cm, spacing in the rows (crosspiece) 22cm, several about 10,000 clumps of mu clump.Wide-narrow row planting, facilitates farm work, can improve permeability, makes full use of light temperature resource, and coordinate the complementary relationship of individual and group, each single file has the growing environment similar in appearance to limit row, thus can strengthen edge effect to greatest extent, improves output.
further, nitrogen fertilizer amount and application process total N content are by per mu yield 1200kg, this season interest rate 0.425 calculates, in practical operation, because of Shen Liang demonstration side, soil property is sand partially, kind is river in Zhejiang Province excellent 12, suitably add fertilizing amount, be specially: carbon ammonium 50kg executed by every mu of base manure, topdress special formulation fertilizer for rice 25kg+ urea 5kg, urea 12kg executed by short fertilizers for potted flowers, protect fertilizers for potted flowers and execute urea 7.5kg, reduce traditional consumption that topdresses, increase ear manuer proportion, favourable summary: by summarizing to the culture technique of 3 paddy rice demonstration fields, draw a set of Dongyang City single cropping rice accurate quantification high yield technique.Keyword: the single cropping rice; Accurate quantification; Culture technique, in control ineffective tillering, improves the percentage of earbearing tiller, increases large spike and grain weight, thus obtains high yield.
beneficial effect of the present invention.
the present invention is according to different soil, kind and design output, accurate quantification is carried out in the strong seedling of cultivation, culturable standard, fertilization mode and water management etc., and by quantitatively operating, be perfect further to rice intensification technology and rational application of fertilizers technology.Make Rice Panicle foot, fringe is large, grain is heavy, output is high.
