Description
Technical field
At field of plant growing technology, more particularly to a kind of microwave for improving agronomic crop seed germination ability
Reason method.
Background technology
In agricultural production, in order to improve seed vitality, Dormancy breaking, promote sprouting and growth of seedling, it will usually to kind
Son carries out pre-sowing treatment, is primarily referred to as more using traditional chemical method, chemical method processing seed using bactericide, desinsection
Agent, inorganic chemical reagent, plant growth regulator etc. handle seed.Though this method is to crops in sterilizing, diseases prevention and disease-resistant, increasing
Production etc. serves certain effect, but there is also many drawbacks.On the one hand, the ring such as seed disease-resistant, cold-resistant in itself, precocity
Border adaptability can not be improved by chemical treatment, but also may suppress the growth of rhizobium；In addition, as people give birth to
The demand of the raising of bioplasm amount and environmental consciousness, food security and organic agriculture steps up not only stops for Demand of Nation, people
Staying in will solve the problems, such as Well fed,well bred., can also realize and eat safe and healthy, traditional chemical treatment method is to agricultural production
Very big negative effect is brought with natural environment, does not adapt to the technical need of Modern Green environmental protection agricultural development.
The content of the invention
The embodiment of the present invention provides a kind of microprocessor method for improving agronomic crop seed germination ability, it is desirable to provide a kind of green
Processing method that colour circle is protected, improving percentage of seedgermination.
The present invention is achieved in that a kind of microwave handling method for improving agronomic crop seed germination ability and arriving, the microwave
Processing method is specific as follows：
Microwave treatment is carried out to the seed in 20~90 day time before seed plantation, the microwave treatment refers to use
The microwave of any frequencies of 2~40GHz carries out uniform irradiation to seed, and controls the power flow density of the microwave to be in (120-
300)mW/cm2, the uniform irradiation refers to that the microwave radiation inhomogeneities is less than 5dB/cm2。
Further, the time that the seed receives microwave irradiation is 60 seconds~110 seconds.
Further, 20~60 day time is interior to the seed progress microwave treatment before planting for the seed.
Further, the frequency of the microwave is 2.45GHz.
Seed is handled using microwave method, microwave handling method belongs to physical method, pollution-free to the external world, helps
In preserving the ecological environment, while it can effectively kill seeds self and carry harmful levels of pathogens, disinfective action is played to seed；Can lifting
Seed resistance against diseases, improve the transportation performance of seed in-vivo tissue capillary channel；Promote seed imbibition, facilitate and speed up kind
Metabolic process in son and plant culture from endosperm to embryo；Enzymatic activity and respiratory intensity are improved, lifting seed sprouts and children
The formation of seedling neologism and growth ability, improve the germinating capacity of seed.
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to embodiments, to the present invention
It is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not used to
Limit the present invention.
While the present invention implements that seed uniformly irradiate to improve the germinating capacity of seed by microwave, externally
Boundary is pollution-free, helps to preserve the ecological environment.
The microwave handling method provided in an embodiment of the present invention for improving agronomic crop seed germination ability, this method include as follows
Step：
Before seed plantation in 20~90 day time, seed is carried out using the microwave of any frequencies of 2~40GHz uniform
Irradiation, and it is (120-300) mW/cm to control the power flow density of microwave2。
In embodiments of the present invention, uniform irradiation refers to control microwave radiation inhomogeneities to be less than 5dB/cm2, microwave radiation
It is more uniform, be more advantageous to control seed to receive microwave irradiation energy, more have the germination percentage that interests improve seed, but can not possibly realize
Absolute uniform irradiation, considers the cost and percentage of seedgermination for improving uniformity, and control microwave radiation inhomogeneities is less than
5dB/cm2；
In addition, from consider cost angle, frequency be 2.45GHz microwave be easiest to obtain, and procurement cost compared with
It is low, therefore consider that selection 2.45GHz microwave is irradiated to seed, to improve the germination percentage of seed；
Seed is handled using microwave method, microwave handling method belongs to physical method, pollution-free to the external world, helps
In preserving the ecological environment, while it can effectively kill seeds self and carry harmful levels of pathogens, disinfective action is played to seed；Can lifting
Seed resistance against diseases, improve the transportation performance of seed in-vivo tissue capillary channel；Promote seed imbibition, facilitate and speed up kind
Metabolic process in son and plant culture from endosperm to embryo；Enzymatic activity and respiratory intensity are improved, lifting seed sprouts and children
The formation of seedling neologism and growth ability, improve the germinating capacity of seed.
Table 1 provides the seed for receiving uniform microwave irradiation and the hair for not going out the seed through microwave irradiation for the embodiment of the present invention
The bud rate table of comparisons, the seed of the microwave treatment in table 1 be before planting 40 days when the microwave treatment that carries out, the frequency that microwave uses
