Description
Nearest Japan Patent NO.675817(patent application NO.28,751/1972 proposes a kind of method of quickening rice seed germination with direct seeding technique.
Be different from and seed rice broadcast on the surface of paddy field soil or imbed conventional method in the paddy field soil with the degree of depth arbitrarily, above-mentioned method is to invent from the type of seeding that seed rice is imbedded in the paddy field soil by the degree of depth of being wished.This method is compared with grafting, and labour cost is low and can obtain higher harvest.
The basis of improving one's methods is to encase seed and live in soil with the degree of depth of about 1Cm with the bag agent that contains calper calcium peroxide prior to seeding.
Under this occasion, the general required air outside of seed rice germination just obtains from the oxygen that peroxide layer produces gradually and emits.The root of seedling also can make paddy rice vertical growth better than common seeding technique.
But, adopt the method for this vernalization, though demonstrate a growth fraction faster through the seedling that germinates like this, and diauxic growth (tillering) will be suppressed or be the effect that does not have what raising at least.
The new improvement method that the purpose of this invention is to provide paddy rice vernalization.This vernalization is undertaken by the seed bag agent of being made up of calper calcium peroxide in fact exactly.Another purpose again of the present invention provides improves the seed rice that germinates and have growth characteristics.
In addition, another purpose of the present invention provides and can germinate in condition under the immersion water and paddy field soil, and the seedling that grows from water demonstrates grows and most secondary (or lateral bud) growths, the just seed rice with shooting property through improveing.
Task of the present invention is clear, uses the seed rice be surrounded by calper calcium peroxide, and the agent of calper calcium peroxide bag just can solve as separating layer and the plant growth regulator that contains the effective dose of mixing with calper calcium peroxide.
So-called plant growth regulator of the present invention (PGR) is interpreted as the single-unit plant influential chemicals thing of biological nature of paddy rice particularly.
Useful PGR is well-known to the single-unit plant, and at " Chemie der pflanzenschutz-Und Schaedling-sbe Kaempfungsmittel " the 4th volume as Wei Gele (R.Weg-ler) work, Berlin, " Plant growth regulato-rs and herbicide antagonists " Noyes Data Corp.Park Ridge of Heidelberg, New York (1977) and John (J, P, Johnson) work, the New Jersey U.S. (nineteen eighty-two) put down in writing.
The PGR that desirable embodiment of the present invention matches with the agent of above-mentioned calper calcium peroxide bag is exactly the polycyclic compound that contains nitrogen that " spy opens clear 52-131599 number " put down in writing.In the classification of the compound of being put down in writing in this patent gazette, desirable compound is a following formula:

2,6, 0
8,11)-12 carbon-3, the disclosed material of 9-diene.
Both coat seed with calper calcium peroxide and PGR, adopt any suitable method as peroxide, PGR and according to circumstances added adjuvant such as adhesive are mixed, again this mixture is put on the skin at the surface of the seed, or various compositions are coated with separately put on the skin can.In desirable embodiment, at first seed is encased with calper calcium peroxide layer or bag agent, coat then and contain the PGR material layer, be coated with the last layer calper calcium peroxide at last again.
PGR uses under the state of dilution, here because most PGR is a just effective cause under quite low concentration.
PGR can adopt calper calcium peroxide or inert carrier to dilute, and the suitable inert carrier that the invention process adopted is gypsum and calcium carbonate.
PGR uses with the mixture of the oxygen discharge agent that resembles calper calcium peroxide and so on that resembles No. 675.817 record of Japan Patent with above-mentioned a kind of polycyclic compound that contains nitrogen in desirable embodiment.
The weight of seed is to calculate with 100, and the amount of calper calcium peroxide and PGR then can change in sizable scope.The weight ratio of calper calcium peroxide and seed is that 1: 1 ratio is preferably as between 1: 10～10: 1, with respect to the amount of the PGR of seed weight, ratio depend on PGR words and also minimum for the amount of the seed weight PGR of unit can be 10

Annotate: tillering capacity is the seedling of tillering to be arranged at the long neat back of the whole seedlings ratio relative with sum.
As shown in table 2, the growing height of (respectively being March 4 and March 6 days) 16 days and 18 days has not after planting treatedly compared only big 0.5% and 1.0% with after handling.Its reason is; Through after processing since the leafing rate is big thus vegetative stage in advance and plant height also reflect, the investigation in March 10 (after planting the 22nd day), littler than what do not handle all through handling growing height afterwards, and this dwindling especially to handle afterwards the most obvious with 2.0%.
Vegetative stage has promptly shifted to an earlier date owing to the cause of processing, promptly is sowing (March 10) back the 22nd day, does not shift to an earlier date 10～37% with having comparing of processing.
There is the ratio of the bud of tillering sowing the 22nd day after (March 10), and that handled is also high by 20～40% than what do not handle.
II) leaf sheath and blade
As shown in table 3, the length of the 1st～the 3rd leaf sheath, the ratio of handling does not have the weak point of processing, and the high more shortening of consumption is obvious more (2.0%＞1.0%＞0.5%) just.
Blade also can be observed same trend, and blade length also is the weak point that the ratio handled was not handled, and consumption is high more, the length of blade is short more.
III) leaf is wide
Be apparent that owing to use chemicals leaf is wide, and very big variation has taken place, leaf is wide to be handled bigger, and this phenomenon consumption is high more obvious more.
IV) diameter of stem
The diameter of stem is handled obviously thick, and this tendency also is that consumption is many more obvious more;
V) dry weight of seedling
The dry weight of table 4 seedling

4 5.9 100 0.201 100 2.0 100
Annotate: dry weight is represented with the mg/ plant.
A) dry amount of part in the air
As shown in table 4, the dry amount of part in the air owing to handle increases, and high, the dry more amount of consumption is just big more.
Maturity of seedling (dry amount/growing height of part in the air) and comparing of not handling have increased 9～61%, and this has shown that the action effect of chemicals is very big.
B) dry amount of root
Because the stretching, extension of root becomes more favourable, so the dry amount of root owing to handle and increased by 10～30%, and thisly is increased in usage amount to handle when higher the effect of processing more remarkable.
