Weighing apparatus promotes neutron absorption to utilize, and avoids seed decay, accelerates the growth of radicle and plumule, shortens the germinating time of seed, must broadcast
Kind seed；
（5）Managing after sowing：After planting spray step（2）The soak of generation, it is 42 ~ 44% to keep water content of substrate, adjusts temperature
It is that 85 ~ 87%, illumination is 80 ~ 100lx for 23 ~ 25 DEG C, ambient humidity, avoids microbiological contamination infested, adjust suitable temperature and humidity,
Accelerate germination to be unearthed, obtain rice bud；
（6）It is managed after bud：The calcium gluconate solution that backward seed sprinkling mass concentration of germinateing is 0.3 ~ 0.5%, continuously spray 2 ~
3 times, it is 61 ~ 63% to keep water content of substrate, adjust temperature be 21 ~ 22 DEG C, ambient humidity be 82 ~ 84%, illumination be 600 ~
700lx promotes fibrous root growth, accelerates the absorption of nutritional ingredient, make seedling early growth vigorous, resistance is strong, shortens the nursery of rice
Time obtains rice seedlings；
（7）Hardening：15 ~ 16 days after germination, it is 10 ~ 12 DEG C that daily noon, which adjusts temperature, and the time is 25 ~ 30 minutes, continuous hardening 3
~ 4 days, obtain rice seedling.
The step（2）Zymotic fluid, the water of 8 ~ 10 times of amounts of peanut meal weight are added in into peanut meal, access lactic acid bacteria,
It ferments 3 ~ 4 days in 37 ~ 39 DEG C, adds in the borax of peanut meal weight 2 ~ 3%, be uniformly mixed, continue fermentation 2 ~ 3 days in 41 ~ 43 DEG C,
Filtering and removing slag obtain zymotic fluid.
The lactic acid bacteria through re-activation, takes precipitation, is in lactobacillus plantarum, lactobacillus acidophilus, streptococcus thermophilus
One or more of arbitrary mixing.
The step（3）Plant ash, by rice husk carry out fully burn after obtain, weight for rice paddy seed weight 30 ~
35%。
The step（4）Matrix, be made of the raw material of following parts by weight：Rice husk 42 ~ 44, corncob 36 ~ 38, chicken manure 27
~ 29, cow dung 23 ~ 25, banana skin 20 ~ 22, bagasse 20 ~ 22, sawdust 15 ~ 17, EM bacterium 3 ~ 4, vermiculite 12 ~ 14, perlite 17 ~ 19,
Graphene 0.6 ~ 0.8.
The rice seedling that the fast soiless method for culturing seedlings of the rice obtains.
It is an advantage of the invention that：The fast soiless method for culturing seedlings of rice provided by the invention, when making the processing of rice paddy seed
Between shorten to 1 day, avoid it is traditional bask seeds and pregermination procedure, germinate within after planting 3 ~ 4 days, rice transplanting can be carried out within 18 ~ 20 days after germination,
Rice shoot utilization rate reaches more than 95%, hence it is evident that improves the breeding efficiency of rice；After seed selection by rice paddy seed be placed in zymotic fluid into
Row impregnates, and zymotic fluid is prepared by lactobacillus-fermented peanut meal, turned waste into wealth, and generates abundant small molecule nutritional ingredient and enzyme
Class inhibits disease pest growth, improves seed enzyme activity, promote germination, shortens germination and the seedling raise period of seed；It will after immersion
