Abstract
The invention discloses a kind of cultural method of ratooning rice, including selecting breeding, presoaking and germinating, nursery, cultivated whole crop field and transplanting rice transplanting, first rice crop cultivation, first rice crop gathers in, ratooning rice manages, regenerates season harvest, the present invention can not only rationally utilize soil, reasonably managed in first rice crop and ratooning rice growth course, the yield of ratooning rice can be increased.
Description
Technical field
The present invention relates to field of agricultural cultivation, more particularly to a kind of cultural method of ratooning rice.
Background technology
Ratooning rice refers to semilate rice and adds accumulation ratooning rice, is the reproducing characteristic using rice, using certain cultivation management measure,
Make the Dormant Buds growth on the rice stub after season rice harvesting, and then a kind of rice for obtaining regeneration season spike of rice makees type.Cause
It regenerates that breeding time in season is short, and the daily output is high, and with save kind, saving of labor, province's medicine, province rice seedling bed, water-saving, that cost is low, benefit is high etc. is excellent
Point, cultivated area expands year by year in recent years, has a surplus for south China rice region one season of plantation rice temperature light resource, plantation double cropping of rice is again
Deficiency and part double rice cropping system are raised the multiple-cropping index, increase the yield per unit area provides effective measures with income.Also become
A kind of important light simplified cropping system of South Rice Region of China Rice Cropping, plays more and more important in China's grain security is ensured
Effect.
The content of the invention
It is an object of the invention to provide a kind of cultural method of ratooning rice, rational management of the present invention, can effectively improve again
Raw rice yield.
To achieve the above object, the present invention adopts the following technical scheme that：
A kind of cultural method of ratooning rice, comprises the following steps：
(1) breeding is selected：Select Early-mid ripening kind of the breeding time within 135d；
(2) presoaking and germinating：Before presoaking and germinating, seed sunlight is disappeared according to 1-2d, when seed soaking is shone using fungicide such as Prochlorazs
Malicious 20-30min, is then cleaned with clear water, when lower warm water immersion 10-12 is small, is then dried in the air half a day, then when warm water immersion 0.5 is small, weight
It is multiple three times, seed shows money or valuables one carries unintentionally germination, when sprouting is grown to 0.5cm long, dresses seed, mixes thoroughly to spread out and dry, in treating；
(3) nursery：Higher, flat, with seeping water moderate, the convenient rice seedling bed of irrigation and drainage as rice the nursery of physical features is selected to use
Ground, digs pine by rice seedling bed, reaches that soil block is in small, broken bits, field face is smooth, pig manure 120-160kg, nitrogen-phosphorus-potassium compound fertilizer 18- are applied in rice seedling bed per acre
22kg；Then uniformly sowing；Rice seedling bed is covered with plastic film, removes film after 20 days, allows rice shoot to divulge information；Three leaves wholeheartedly after,
At the 25-28 days length of time rice seedlings grow, spray imidacloprid+Buprofezin, while imposes urea+25-30 jins of potash fertilizer per acre；
(4) whole crop field and transplanting rice transplanting are ploughed：Plough whole crop field and big Tanaka applies base fertilizer, it is compound to apply 50-55 jins of chloros per acre
Fertilizer, then sheds rice shoot to big Tanaka using wide-and narrow-row；
(5) first rice crop is cultivated：After rice transplanting rice shoot is turned green, tillering stage, the urea for applying 4-6kg per acre makees tillering fertilizer；It is pregnant
Ear period applies the composite fertilizer of 10kg, 5kg potash fertilizer per acre；
(6) first rice crop gathers in：Gathered in the first rice crop stage of yellow ripeness, in harvesting process, stay height as rice stub very little 7-8；
(7) ratooning rice manages：After first rice crop harvesting, weeds are removed in time, and righting rice stub, applies 30 jin of urea per acre, multiple
30 jin of Hefei；After first rice crop harvest in 1O days, field should be kept to moisten, gather in later 24-3O days, ratooning rice is raised into people's heading
Florescence, field face keep shallow water, and later stage field holding is dry easily to fall into sufficient state；Ratooning rice prevents pest and disease damage in time during growing up；
(8) season harvest is regenerated：Ten maturation of rice to be regenerated is gathered in.
Beneficial effects of the present invention：The present invention can not only rationally utilize soil, in first rice crop and ratooning rice growth course
Reasonably managed, the yield of ratooning rice can be increased.
Embodiment
Technical scheme is further described below.
A kind of cultural method of ratooning rice, comprises the following steps：
(1) breeding is selected：Select Early-mid ripening kind of the breeding time within 135d；
(2) presoaking and germinating：Before presoaking and germinating, seed sunlight is disappeared according to 1-2d, when seed soaking is shone using fungicide such as Prochlorazs
Malicious 20-30min, is then cleaned with clear water, when lower warm water immersion 10-12 is small, is then dried in the air half a day, then when warm water immersion 0.5 is small, weight
It is multiple three times, seed shows money or valuables one carries unintentionally germination, when sprouting is grown to 0.5cm long, dresses seed, mixes thoroughly to spread out and dry, in treating；
(3) nursery：Higher, flat, with seeping water moderate, the convenient rice seedling bed of irrigation and drainage as rice the nursery of physical features is selected to use
