Abstract
The invention relates to a japonica-type conventional paddy rice breeding and cultivation technology, and relates to the field of agriculture. The invention especially relates to a paddy rice cultivation technology. With the japonica-type conventional paddy rice breeding and cultivation technology provided by the invention, a paddy rice easy lodging phenomenon can be solved, rice ear size is uniform, and yield is high. The technology is characterized in comprising the following steps: 1, breeding is carried out, wherein an ear row nursery is built; 500-1000 typical single-ear seeds are selected, and are respectively sowed and transplanted; the rice is planted in 5-10 Mu of ear row nursery; 2, strong seedlings are cultivated, and sowing is carried out at an appropriate time. A paddy nursery seedling sowing amount per Mu is 25-30kg, and a dry nursery seedling sowing amount per Mu is 35-40kg; 3, the transplanting specifications are that 20000-22000 seedlings are transplanted in every Mu when a seedling age is approximately 35 days; 4, fertilizer and water management are carried out according to a principle that heavy application should be carried out in an early stage, stable application should be carried out in a middle stage and supplementary application should be carried out in a late stage; and 5, available potassium content in mountain area soil is low, such that requirements of paddy rice growth cannot be satisfied. Therefore, if potassium is applied, a significant yield increase effect is provided. Calculated according to K2O potassium, when a potassium fertilizer dose is within a range of 5-10kg/667m<2>, the potassium fertilizer dose is significantly positively correlated with yield.
Description
Technical field
The invention belongs to agriculture field, especially relate to the culture technique of a kind of paddy rice.
Background technology
Paddy rice institute knot reality and paddy, claim rice or rice after shelling.Nearly half population, comprises the population in almost whole East Asia and Southeast Asia in the world, is all food with rice.Paddy rice is mainly distributed in the subtropical and tropical zones in Asia and Africa.The cultivation history of rice can trace back to the Hunan China before the about Christian era before 12000 ~ 16000 years paddy rice.In 1993, associating archaeological team of Sino-U.S. found world's ancient rice the earliest at Dao County Yu Chanyan, apart from about 14000 ~ 18000 years the presents.Paddy rice, after China widely plants, propagates into India westwards gradually, and Middle Ages introduce south of europe.Except the ecotype being called upland rice, paddy rice all in the torrid zone, the coastal plain in the area such as half torrid zone and temperate zone, tidal delta and river basin waterflooding cultivate.Seed is broadcast on ready rice seedling bed, is transplanted to and has the depth of water of dike to be in the rice field of 5 ~ 10cm around, soak in water in the season of growth always when seedling age is 20 ~ 25 days.The grain of rice of results is called paddy, has crust, mills and often shell is removed together with rice bran layer, sometimes add skim glucose and talcum powder, make the grain of rice glossy.Only remove the rice of shell when milling in brown rice, be rich in starch, and contain the protein of about 8% and a small amount of fat, containing thiamines, nicotinic acid, vitamin b3, iron and calcium.Grind the rice of decapsidate and rice bran polished rice or rice, its nutritive value reduces greatly.
Beijing-Tianjin-Tangshan Dao Qu is China's fine quality rice producing region, and its polished rice produced is due to good palatability liking deeply by northern China resident.But in recent years because these ground weather conditions there occurs change, water resource is day by day deficient, Beijing-Tianjin-Tangshan Dao Qu fine quality rice is produced area and is reduced comparatively large, and the high yield and high quality rice varieties being applicable to this area's need of production is deficienter.And the easy lodging phenomenon easily occurred for paddy rice and the unequal problem of spike of rice size, be also badly in need of solving.
Summary of the invention
The present invention is exactly for the problems referred to above, provides a kind of and solves paddy rice and easily to lodge phenomenon and the seed selection of the high a kind of round-grained rice type conventional rice of the even output of spike of rice size and culture technique.
To achieve these goals, the present invention adopts following technical scheme.
The seed selection of round-grained rice type conventional rice and culture technique, is characterized in that, comprise the following steps.
One, breeding, sets up head progeny row garden and selects typical Dan Sui 500 ~ 1000, sow respectively, transplant, plantation totally 5 ~ 10 mu, head progeny row garden.Collect breeder's stock, reject the different head progeny row of phene, by meeting this varietal characteristic, show that consistent head progeny row is mixed receives to obtain breeder's stock.Breeding original seed, expanded by breeder's stock numerous, each link aborning should be avoided mixing, rogueing 2 ~ 3 times, mixes and receives to obtain original seed.
Two, cultivate strong seedling, proper seeding, watery ricenursery mu seeding quantity is at 25 ~ 30kg, and the dry rice seedling mu amount of broadcasting 35 ~ 40kg, rice seedling bed uses sufficient base manure, early executes wean fertile, executes ingeniously to send and transfer fertilizer, cultivate of the right age band tiller and strengthen seedling.
Three, plant specification, about the 35 days length of time rice seedlings grow, plant 2.0 ten thousand ~ 2.2 ten thousand caves, seeding row spacing 13cm × 23cm for every mu, every cave 2 ~ 3 seedling, plants sufficient mu Basic Seedling about 70,000, and the field that fertility is low can in right amount be planted more.
Four, rich water quality management, in line with " front heavy, in steady, rear benefit " principle, mu executes pure nitrogen level 18 ~ 22kg, base manure 50%, tillering fertilizer 20%, fringe granulated fertilizer 30%.Enough seedlings put field, and gradation is gently put, timely rehydration.Control peak seedling and be no more than 300,000, become fringe 220,000 ~ 230,000, receive and cut off the water supply for first 7 ~ 10 days.
Five, Soil Available potassium content in mountain area is lower, can not meet paddy growth, executes potassium volume increase extremely remarkable.Potassium Fertilizer is with the metering of K2O potassium, and within the scope of 5 ~ 10kg/667m2, Potassium Fertilizer and output are remarkable positive correlation.
As a kind of preferred version, base manure will strive executing the organic manure such as farmyard manure more, the quick-acting chemical fertilizer of appropriate compounding application.Farmyard manure is evenly sprinkling upon face, field and then ploughs under in earth before ploughing spring.Every 667m
2execute 1200 ~ 2200kg fertile.
Beneficial effect of the present invention.
The paddy growth amount of being planted by the method for the invention is large, and output is high, and stem stalk is strengthened, and lodging resistance is good, and adaptability is good.Major defect: this kind is longer for breeding time in Beijing-tianjin-tangshan Area.Produce suggestion: the planting early enough as far as possible in Beijing-tianjin-tangshan Area, ensure that there is sufficient time grouting in the later stage, this rice yield potentiality is released.
Embodiment
