Description
Technical field
The present invention relates to a kind of method improving standardization rice seed germination ability, belong to rice paddy seed sorting field.
Background technology
Along with minimizing and the increase of labor cost of China rural laborer, improve Rice Production by mechanization and imitate
Rate is to promote Stabilizing Grain Output and the Important Action of increasing peasant income.Being smoothed out in order to ensure mechanization production, paddy growth is sent out
Neat, the synchronization educated are important preconditions.Under same ecological zone, how to accomplish the consistent of rice growth
Property, children's (seedling) Seedling neat, even and strong be basis.Therefore, in the case of mechanization production, to the purity of rice paddy seed, cleanliness and
The uniformity is proposed new, higher requirement.
Existing Cereal seed quality performs in standard GB4404.1-2008, and land for growing field crops seed purity of hybrid rice should not
Less than 96%, cleanliness is not less than 98%, germination percentage is not less than 80%；Land for growing field crops hybrid corn seed purity should be not less than 95%,
Cleanliness is not less than 99%, germination percentage is not less than 85%.Existing oil plant class seed quality performs in standard GB4407.2-2008,
Land for growing field crops cross-bred rape seed purity should be not less than 85%, cleanliness is not less than 98%, germination percentage is not less than 80%；Land for growing field crops Semen arachidis hypogaeae
Seed purity should be not less than 96%, cleanliness is not less than 99%, germination percentage is not less than 80%.Calculate with 100 seeds, due to Oryza sativa L.
The impact of purity, cleanliness and germination percentage, live or educate (seedling) Seedling miss rate of (seedling) Seedling should be more than 20%, after directly affects
Continuous do mechanization operation.Meanwhile, in existing seed quality execution standard the most not using the seed uniformity as the index of rice paddy seed
One of.Studies have reported that, the plumpness of seed will directly affect the growth promoter of the germination percentage of seed, planting percent and rice shoot,
And then affect rice yield.
The defect of standard is performed, the general application rate using increasing rice paddy seed in production in order to make up existing seed quality
Carry out live and educate (seedling) Seedling, and increasing in follow-up farming operates and select Seedling, thinning operation, on the one hand add seed consumption,
Production cost increases；On the other hand, the operation of follow-up farming and do mechanization operation have also been increased the weight of.Although sowing seeds technology is former
It is capable of the effect of province's kind, potentiation, volume increase in reason, but rice paddy seed is required to higher in purity, cleanliness and the uniformity by it,
There is no effective seed separation method the most supporting.
Summary of the invention
For meeting the sowing seeds technology high request to rice paddy seed, improve standardization Oryza sativa L. it is desirable to provide a kind of
The method of seed germination ability, the method can effectively coordinate the sowing seeds technology requirement to rice paddy seed, uses multi-cascade
Close screening and realize the cleanliness of rice paddy seed 100%；Multi-stage combination screening is used to improve rice paddy seed size, mass of 1000 kernel, colourity
Uniformity；Standardization rice paddy seed is provided, it is achieved the purpose of one Seedling of a seed, consumption is accurate for sowing seeds technology；Really
Protect the concordance of rice seed germination ability, it is achieved seedling neat, even and strong.
To achieve these goals, the technical solution adopted in the present invention is:
A kind of method improving standardization rice seed germination ability, it is characterised in that comprise the steps:
S1 carries out physically screening to rice paddy seed, to improve the cleanliness of rice paddy seed；
Rice paddy seed after step S1 is processed by S2 carries out liquid screening, utilizes the gravity of rice paddy seed to satisfy to realize seed
Expire grain and half full grain or the separation of blighted grain；
Rice paddy seed after step S2 is processed by S3 carries out aberration sorting, the RGB scope of established standards seed, rejects and does not exists
Rice paddy seed in the range of the RGB of standard seed.
Thus, using physically screening, liquid screening and aberration sorting to combine the cleanliness realizing rice paddy seed 100%, it is broadcast
Amount of planting screens the few 40%-70% of seed consumption than existing screen for seeds selecting technology, and planting percent is more than 90%.
According to embodiments of the invention, it is also possible to the present invention is further optimized, below for the skill formed after optimizing
