Description

A kind of contrast difference's seed selection late rice new varieties process
Technical field
The invention belongs to agricultural technology field, particularly a kind of contrast difference's seed selection late rice new varieties process.
Background technology
For many years, southern rice cultivation is arbitrarily to recommend to select by seeds company, pungent all the year round with very big blindness Arduous hardship, harvest is taken a chance, is often yielded poorly, and poor quality, rice lodging phenomenon happens occasionally.
The content of the invention
The present invention lacks science, paddy field soil species fertilizer not enough standardized administration to overcome existing rice cultivation, there is provided a kind of method Novelty, simple to operate, low cost, a kind of contrast difference's seed selection late rice new varieties process of instant effect, preferably good child-rearing.
Technical solution of the invention is such：A kind of contrast difference's seed selection late rice new varieties process, it is special Levy is that its step method is：
Step 1, selectes kind：There are rich excellent 568, Toyota excellent 981, state good excellent 7633, dragon Feng You 139, U.S. excellent 622；
Step 2, land used treatment：P in soil H values 6.2, containing organic matter 2.8%, full nitrogen 15%, full phosphorus 0.05%, full potassium 0.68%, soil Middle fertility, uniformity, abundant water, irrigation and drainage are convenient, are periodical water-logging Sandy soil fields；
Step 3, fixed point is chosen：5 kinds are divided into 5 treatment groups, each treatment group leader 500cm, 400cm wide, random protection side Formula, control is not set, and periphery sets protection row；
Step 4, process operation：Set up 5 cells, ridge isolation, ridge 30cm wide, 15cm high separately, and use farmland plastic sheeting, Parcel is separated by its fertilising：Containing 64% phosphoric acid diamines 280kg/hm2,, tea seed bran 80kg/hm2, urea 280kg/hm2, containing 45% Composite fertilizer 280kg/hm2, mix rice transplanting field herbicidal 16 and wrap/hm2,Dressing of turnning green stage 135kg/hm2, potassium chloride 280kg/hm2, Mixing applies rush tiller and attacks ear manuer, and regular pesticide removes insect pest；
Step 5, the selection result：Heading flowering, the young fringe of kind Toyota excellent 981 is secondly by stages state good excellent 7633 earliest, beautiful Excellent 622, panicle primordium dif ferentiation stage difference 5d, again to rich excellent 568, the panicle primordium dif ferentiation stage difference 6d of dragon Feng You 139, Toyota excellent 981 takes out Ear period does sth. in advance 5d than other 4 kinds, and the maturity period does sth. in advance 8 d than remaining 4 kind, and the time of infertility shortens 8 than remaining 4 kind D, is prevented effectively from cold dew wind；
Its yield is up to imperial Feng You 139, is 8004 kg/hm2, it is secondly U.S. excellent 622, it is 7403.7 kg/hm2, state is good Excellent 7633, it is 7253.6 kg/hm2, Toyota excellent 981 is 7003.5 kg/hm2, excellent 568 are won, it is 6553.635kg/hm2, it is most It is low；
Toyota's excellent 981 breeding time is 115d, belongs to middle late-maturing variety, and the photosensitive soft rice type of the multi-spike-type that fringe is short, setting percentage is high is excellent Matter Hybrid Rice Varieties, the yield of imperial Feng You 139 is up to 8004kg/hm2, secondly U.S. excellent 622, state good excellent 7633, Toyota excellent 981 be General kind.
Divide 5 interval experiments, in process points, each process points has been marked, and the field management irrigation and drainage phase, is sprayed On the liquid date, ear flowering date, ripe date, except seedling is weeded the fields the date.
Present invention advantage compared with prior art is：Selection of land simplifies, and scheme is novel, and field management is convenient, side
Method reliability, selected good child-rearing, substantially, low cost, operation is easy for effect.
Specific embodiment
The present invention is described specifically below
First, materials and methods：
1st, kind is tested：For examination Varieties In Late Rice totally 5, excellent 568, Toyota excellent 981, state good excellent 7633, Long Fengyou is respectively won 139th, U.S. excellent 622.Above kind is provided by breeding industry Co., Ltd of Guangxi state.
2nd, experimental plot overview：To test that be located at Yulin City Fu Mian areas Shatian town Shatian cottage back slope in late rice in 2014 old just now Peasant household's farmland covered by contract, abundant water, irrigation and drainage are convenient, area 1354m2, preceding as paddy rice, experimental plot is periodical water-logging Sandy soil fields, soil PH value 6.0, containing organic matter 2.72%, full nitrogen 0.15%, full phosphorus 0.07%, full potassium 0.64%, soil fertility is medium, and uniform one Cause.
3 experimental designs：Experiment sets 5 treatment altogether, each treatment 20m2, 5m long, 4m wide, each kind are 1 treatment, are adopted Random alignment mode is used, control is not set, periphery sets protection row.In addition to kind difference, other conditions are consistent.
4th, process of the test：The experiment sowing time is on July 21st, 2014, and transplanting time is August 2.August is set by experiment on the 1st Count 5 ridge isolation of cell, ridge 30cm wide, 15cm high, and be separated by with agricultural plastic film parcel.Base manure applies Guangxi Luzhai The Diammonium phosphate (DAP) of chemical fertilizer factory（Content 64%）250kg/hm2, tea seed bran 75kg/hm2.The urea 250kg/ that August is produced with rivers and ponds on the 10th hm2, the Yang Feng composite fertilizers of Hubei Yang Fengchang productions（Content 45%）250kg/hm2Mixing rice transplanting field herbicidal 15 wraps/hm2, August 25 Daily rivers and ponds urea 125kg/hm2Applied down as dressing of turnning green stage, Canadian potassium chloride 250kg/hm2Mixing applies rush tiller and attacks ear manuer.Disease pest Evil prophylactico-therapeutic measures is identical.
2nd, result and analysis：
1st, phenological period and upgrowth situation：
The different Different Rice Varieties During Growth Durations of table 1 compare
As it can be seen from table 1 the phenological period performance of tested variety is variant.Each kind is in the flowering of earing successively of October 3, kind The excellent 981 children fringe of Toyota is September 5 earliest by stages, is secondly September 10 to state good excellent 7633, U.S. excellent 622 panicle primordium dif ferentiation stage, poor Different 5d, is September 11, difference 6d to rich excellent 568, dragon Feng You 139 panicle primordium dif ferentiation stages again.October 3 at heading stage of Toyota excellent 981 Day does sth. in advance 5d than other 4 kinds, and November 9 maturity period does sth. in advance 8d than remaining 4 kind, and the time of infertility is accordingly than remaining kind Short 8d, effectively avoids cold dew wind from endangering.
2nd, rice varieties plant economic characters
The different rice varieties plant economic characters of table 2
As shown in Table 2, the yield highests of imperial Feng You 139, are 8004kg/hm2, secondly for U.S. excellent 622, state good excellent 7633, Toyota is excellent 981, yield is respectively 7403.7kg/hm2, 7253.6kg/hm2, 7003.5kg/hm2.Win excellent 568 yield minimum, be 6553.35kg/hm2。
3rd, conclusion：
Toyota's excellent 981 breeding time is 115d, belongs to middle late-maturing variety, the photosensitive soft rice type high-quality of the multi-spike-type that fringe is short, setting percentage is high Hybrid Rice Varieties.The yield of imperial Feng You 139 is up to 8004kg/hm2, secondly U.S. excellent 622, state good excellent 7633, Toyota excellent 981, produces Amount is respectively 7403.7kg/hm2, 7253.6kg/hm2, 7003.5kg/hm2。
