Abstract
The invention discloses a paddy rice seed pregermination method. When radical buds of paddy rice grow up to a specified standard, a physical method is used to control the growth of the radical buds, thereby widening the optimal period of seeding, so that the aims of labor conservation, cost conservation, effect enhancement and labor intensity relief are achieved. Compared with the traditional paddy rice pregermination seeding, the method can improve the seeding quality remarkably, and in particular to applying the method to mechanized direct seeding of paddy rice, the resistance of the machinery transmission of the seeds can be reduced obviously, so that the sprouts can pass through a seed passage smoothly and the seeding quality is guaranteed; when the paddy rice seed sprouts are prepared, the 'seed soaking-germination accelerating' process does not need to be repeated everyday; and the method has the characteristics of simplicity, convenience, easiness for mastering the technology and the like, and can be widely applied to paddy rice cultivation.
Description
Technical field
The present invention relates to paddy rice vernalization and sowing, specifically a kind of with rice bud paddy radical bud, control the radical bud growth by physical means, thereby reach the method for operating that is conducive to rice growing.
Background technology
China is the first in the world populous nation, also is one of main agriculture country in the world.Paddy rice is the most important cereal crops of China.Yet rice cropping is mainly take the vernalization sowing as main, along with human resources shift to the secondary industry and the tertiary industry; the agricultural workforce reduces increasingly; paddy rice is gradually in large-scale production, and the agricultural mechanization popularity rate is more and more higher, and Mechanization Planting Technology is penetrated among transplanting, the machine direct seeding technique.
And Mechanization sowing be always bright bud directly sowing be main, radical bud length to bud paddy has very strict requirement, because bright blastogenesis length is uncontrollable, a large amount of artificial, the facility of vernalization sowing need of work, adapt circumstance condition etc. are corresponding with it, the careless slightly seeding quality that namely causes descends, and causes the paddy rice underproduction.And at present the applied chemistry material carries out the long control of rice root blastogenesis, and it is slow to have the effect of the coming time, the defective such as efficiency time is long, effect is relatively poor, contaminated environment and not being employed.
Summary of the invention
The invention provides a kind of physical method of controlling the growth of rice bud paddy radical bud, solve people and when mechanical planting, usually continued growth because of bud paddy radical bud, the problem that causes seeding quality to descend, and at present Mechanization sowing take a lot of work, the problem of time-consuming, the duplication of labour.
The present invention adopts following technical scheme for achieving the above object:
A kind of accelerating germination of rice seed method is characterized in that: may further comprise the steps:
The seed soaking of A, rice paddy seed:
Get the rice paddy seed without worm-eaten, mature and plump, in the netted seed packet of packing into, select free of contamination farmland irrigating water, be in the 20-35 ℃ of condition in temperature, soak seed after 30-60 hour and to take out, then eluriate 1-3 time with the farmland irrigating water, place on the clean water mud ground face placement stand-by after 1-2 hour;
B, accelerating germination of rice seed:
Together with netted seed packet, placing temperature is 15-25 ℃ with the rice paddy seed of seed soaking, humidity vernalization in the insulating box of 70-80%, and it is for subsequent use to stop vernalization after the broken chest of rice paddy seed shows money or valuables one carries unintentionally;
C, startup rice bud paddy radical bud growth control:
With 5-15 centimetre of the bright bud paddy tiling of paddy rice thickness, placing temperature is 15-25 ℃, and humidity was in the environment of 40-70%, stirred one time bud paddy every 2 hours, until bright bud bud paddy moisture reaches 14-15%;
D, maintenance rice bud paddy radical bud growth control:
By the rice bud paddy of growth control, laying temperature is 15-20 ℃, and humidity is in the environment of 40-50%, grows between control time 0-40 days;
E, releasing rice bud paddy radical bud growth control:
With the bud paddy of growth control, place in 15-35 ℃ the warm water, soaks after 3-5 hour and take out, namely remove growth and control stand-by.
For adapting to length 5-10 centimetre of root, length 1-3 centimetre manual sowing of bud, another kind of technical scheme of the present invention is:
A kind of accelerating germination of rice seed method is characterized in that: may further comprise the steps:
The seed soaking of A, rice paddy seed:
Get the rice paddy seed without worm-eaten, mature and plump, in the netted seed packet of packing into, select free of contamination farmland irrigating water, be in the 25-35 ℃ of condition in temperature, soak seed after 30-50 hour and to take out, then eluriate 1-3 time with the farmland irrigating water, place on the clean water mud ground face placement stand-by after 1-2 hour;
B, accelerating germination of rice seed:
Together with netted seed packet, placing temperature is 25-35 ℃ with the rice paddy seed of seed soaking, and humidity is vernalization in the insulating box of 70-80%, and the length of root reaches 5-10 centimetre, and when the length of bud reached 1-3 centimetre, it was for subsequent use to stop vernalization;
C, startup rice bud paddy radical bud growth control:
With 5-15 centimetre of the bright bud paddy tiling of paddy rice thickness, placing temperature is 25-35 ℃, and humidity was in the environment of 40-70%, stirred one time bud paddy every 1 hour, until bright bud bud paddy moisture reaches 14-15%;
D, maintenance rice bud paddy radical bud growth control:
By the rice bud paddy of growth control, laying temperature is 25-35 ℃, and humidity is in the environment of 40-50%, and the growth control time is between 0-15 days;
E, releasing rice bud paddy radical bud growth control:
The control bud paddy that will grow places in 15-35 ℃ the warm water, soaks after 3-5 hour and takes out, and namely removes growth and controls stand-by.
The inventive method is compared with the sowing of bright bud, can significantly improve seeding quality, especially be applied to rice mechanization live on, can obviously reduce the resistance of the mechanical transfer kind period of the day from 11 p.m. to 1 a.m, make bud paddy swimmingly by kind of a subchannel, guarantee seeding quality; Making the rice machine sowing period of the day from 11 p.m. to 1 a.m, do not need every day and all repeat " seed soaking-vernalization " operation, have by comparison saving of labor, abridged edition, simple to operate, be easy to the advantage such as grasp.
