The invention discloses a kind of method for culturing seedlings of paddy rice.The method for culturing seedlings includes seed selection, vernalization, sowing and the prevention and control of plant diseases, pest control.Method for culturing seedlings of the invention by optimizing paddy rice, strengthens the growing way of rice shoot, and then significantly improve the yield of paddy rice.

Description

The method for culturing seedlings of paddy rice
Technical field
The present invention relates to a kind of implantation methods of crops, more particularly to a kind of method for culturing seedlings of paddy rice.
Background technology
By promoting the hybrid rice of Academician YUAN Long-ping, the Chinese population grain for accounting for world's a quarter is not only solved, and Solve " bottleneck " that many Rice Cropping state yield in the world are difficult to improve, so as to have very big side to alleviating world food crisis Help.
This is a gratifying progress, but the reduction in the growth arable land with China human mortality, production-scale narrow and small, water resource A series of problems, such as shortage, arid threat, propulsion of conceding the land to forestry, objectively all exacerbates the demand contradictory of grain, adds The science and technology of China more falls behind and service system is weak, more indicate the current food problem of China also exist a variety of hidden danger and Risk can not look down upon.
And as the high-tech transgenosis relied on now, although the quality and character of paddy rice can be changed, but farming can not be improved The yield of thing, simultaneously as transgenic seed price is much higher than common breeding seed, so as to add agricultural planting cost.
Optimum proportion of crop planting method is found out from actual plantation experience, grain yield is improved with this, then be one can The effective method of row, and the method for culturing seedlings of paddy rice plays vital effect to the whole yield for improving paddy rice.
The content of the invention
It is an object of the invention to overcome in the presence of prior art above-mentioned not enough there is provided a kind of method for culturing seedlings of paddy rice.Should Method for culturing seedlings includes seed selection, vernalization, sowing and the prevention and control of plant diseases, pest control.Method for culturing seedlings of the invention by optimizing paddy rice, strengthens rice shoot Growing way, and then significantly improve the yield of paddy rice.
In order to realize foregoing invention purpose, the invention provides following technical scheme:
Method for culturing seedlings of the present invention, including seed selection, vernalization, sowing and the prevention and control of plant diseases, pest control, it is characterised in that specific method is such as Under:
(1) choose seeds:The flat kind floated in seed selection, removing is floated for 10% sodium chloride solution with mass ratio, the full of sedimentation is pulled out Seed rice, clear water is cleaned, standby;
(2) vernalization:48~72h will be shone in the sun through obtained full seed rice of choosing seeds;With 1% limewash at 10~15 DEG C Soak seed 24~48h;Then seed is pulled out, cleaned with clear water;Seed is wrapped up using wet cloth, is placed in 10 in 30~35 DEG C of incubators ~16h;
(3) sow:Selection physical features is higher, flat, with seeping water the convenient rice seedling bed of moderate, irrigation and drainage as the nursery land used of paddy rice, will Pine is dug in rice seedling bed, reaches that soil block is in small, broken bits, field face is smooth, a trench digging point railway carriage or compartment, the wide 120~140cm in railway carriage or compartment, 20~30cm of furrow width, and ditch depth 10~ 15cm;Apply 120~160kg of pig manure, 18~22kg of nitrogen-phosphorus-potassium compound fertilizer in every mu of rice seedling bed;Then uniform sowing;Will with plastic sheeting Rice seedling bed is covered, and is removed film after 20 days, is allowed rice shoot to divulge information;
(4) prevention and control of plant diseases, pest control:Rice seedling bed should be noted rice seedling blight, pythium rot and planthopper pest and disease damage, be entered if necessary using agricultural chemicals Row preventing and treating.
Implantation methods of the present invention strengthen the growing way of rice shoot, and then improve by the method for culturing seedlings of reasonably optimizing paddy rice The yield of follow-up paddy rice.
Applicant has found by experiment for many years, will shine 48~72h in the sun through obtained full seed rice of choosing seeds, can make seed rice Moisture content it is consistent.Soaked seed 24~48h, then pull seed out at 10~15 DEG C with 1% limewash, cleaned with clear water; Seed is wrapped up using wet cloth again, 10~16h in 30~35 DEG C of incubators is placed in, can not only improve the disease and insect resistance energy of seed rice Power, and the germination percentage of seed rice can be improved.Preferably, seed is wrapped up using wet cloth in the step (2), is placed in 30~35 DEG C 12h in incubator.
Base manure is done using pig manure and nitrogen-phosphorus-potassium compound fertilizer, the growing way of rice shoot can be strengthened.Preferably, every mu in the step (2) Apply pig manure 150kg, nitrogen-phosphorus-potassium compound fertilizer 20kg in rice seedling bed.Preferably, in step (2) nitrogen-phosphorus-potassium compound fertilizer N P and K weight Than for 1~1.5:0.5~0.8:0.8~1.It is further preferred that in step (2) nitrogen-phosphorus-potassium compound fertilizer N P and K weight Than for 1:0.5:0.8.By to the preferred of rice seedling bed base manure, can balanced seedling growth nutritional ingredient, to reach further increasing The purpose of strong rice shoot growing way.
The beneficial effects of the present invention are:
Method for culturing seedlings of the present invention, including seed selection, vernalization, sowing and the prevention and control of plant diseases, pest control.The method for culturing seedlings rice seed germination Rate is high.Method for culturing seedlings reasonable selection pig manure and nitrogen-phosphorus-potassium compound fertilizer of the present invention make base manure simultaneously, and it is compound to adjust N P and K The weight ratio of N P and K three in fertilizer, the nutritional ingredient required for balanced seedling growth development, promotes seedling growth, growing way Well, it is that increasing production of rice lays the first stone.
