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 rice bud paddy radical bud is controlled to radical bud by physical means and grows, thereby reach the method for operating that is conducive to rice growing.
Background technology
China is one of main agriculture country in the ，Ye Shi of the first in the world populous nation world.Paddy rice is the most important cereal crops of China.Yet rice cropping mainly be take vernalization sowing as main, along with human resources shift to the secondary industry and the tertiary industry; agricultural workforce reduces increasingly; paddy rice is gradually in large-scale production, and agricultural mechanization popularity rate is more and more higher, and Mechanization Planting Technology is penetrated among transplanting, 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, due to long uncontrollable of bright blastogenesis, a large amount of artificial, the facility of vernalization sowing need of work, adapt circumstance condition etc. in contrast should, the careless slightly seeding quality that causes declines, and causes the paddy rice underproduction.And at present applied chemistry material carries out that rice root blastogenesis is long to be controlled, there is the effect of the coming time slow, defects such as efficiency time is long, effect is 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, solved people usually grows because bud paddy radical bud is lasting when mechanical planting, the problem that causes seeding quality to decline, 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 method, is characterized in that: comprise the following steps:
The seed soaking of A, rice paddy seed:
Get the rice paddy seed without worm-eaten, mature and plump, pack in netted seed packet, select free of contamination farmland irrigating water, in temperature, be in 20-35 ℃ of condition, soak seed after 30-60 hour and to take out, then with farmland irrigating water, eluriate 1-3 time, be placed on clean water mud ground face, place after 1-2 hour stand-by;
B, accelerating germination of rice seed:
By the rice paddy seed of seed soaking, together with netted seed packet, being placed in temperature is 15-25 ℃, and humidity vernalization in the insulating box of 70-80% stops vernalization after the broken chest of rice paddy seed shows money or valuables one carries unintentionally standby;
C, the growth of startup rice bud paddy radical bud are controlled:
By the bright bud paddy tiling of paddy rice thickness 5-15 centimetre, being placed in temperature is 15-25 ℃, in the environment that humidity is 40-70%, stirs one time bud paddy every 2 hours, until bright bud bud paddy moisture reaches 14-15%;
D, the growth of maintenance rice bud paddy radical bud are controlled:
The rice bud paddy of controlling by growth, laying temperature is 15-20 ℃, in the environment that humidity is 40-50%, grows between control time 0-40 days;
E, the growth of releasing rice bud paddy radical bud are controlled:
The bud paddy that growth is controlled, is placed in the warm water of 15-35 ℃, soaks after 3-5 hour and takes out, and removes growth control stand-by.
For adapting to length 5-10 centimetre of root, the manual sowing of length 1-3 centimetre of bud, another kind of technical scheme of the present invention is:
A method, is characterized in that: comprise the following steps:
The seed soaking of A, rice paddy seed:
Get the rice paddy seed without worm-eaten, mature and plump, pack in netted seed packet, select free of contamination farmland irrigating water, in temperature, be in 25-35 ℃ of condition, soak seed after 30-50 hour and to take out, then with farmland irrigating water, eluriate 1-3 time, be placed on clean water mud ground face, place after 1-2 hour stand-by;
B, accelerating germination of rice seed:
By the rice paddy seed of seed soaking, together with netted seed packet, being placed in temperature is 25-35 ℃, vernalization in the insulating box that humidity is 70-80%, and the length of root reaches 5-10 centimetre, when the length of bud reaches 1-3 centimetre, stops vernalization standby;
C, the growth of startup rice bud paddy radical bud are controlled:
By the bright bud paddy tiling of paddy rice thickness 5-15 centimetre, being placed in temperature is 25-35 ℃, in the environment that humidity is 40-70%, stirs one time bud paddy every 1 hour, until bright bud bud paddy moisture reaches 14-15%;
D, the growth of maintenance rice bud paddy radical bud are controlled:
The rice bud paddy of controlling by growth, laying temperature is 25-35 ℃, in the environment that humidity is 40-50%, the growth control time is between 0-15 days;
E, the growth of releasing rice bud paddy radical bud are controlled:
To grow and control bud paddy, be placed in the warm water of 15-35 ℃, and soak after 3-5 hour and take out, remove growth control stand-by.
The inventive method is compared with bright bud sowing, can significantly improve seeding quality, is especially applied to rice mechanization live upper, can obviously reduce the resistance of the mechanical transfer kind period of the day from 11 p.m. to 1 a.m, makes 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 advantages such as grasp.
