Description

A kind of breeding method of rice seedling
Technical field
The invention belongs to agricultural plantation technology field more particularly to a kind of breeding methods of rice seedling.
Background technique
Rice is important one of the cereal crops in China, is occupied an important position in national economy, sown area, total Produce the first place that cereal crops are occupied with per unit area yield, it is seen that the importance of rice.Rice Cropping process is cumbersome, generally can be divided into: rice shoot Cultivation, rice transplanting, site preparation, transplanting and field management.Seedling cultivation is the first step of Rice Cropping, only the premise in rice shoot health It is lower to obtain good rice yield.
Therefore, it is necessary to a kind of breeding method of novel rice rice shoot be designed, to be used to cultivate the rice shoot of healthy growth.
Summary of the invention
Present invention aims to overcome that the shortcomings of the prior art, and a kind of breeding method of rice seedling is provided, it should Method can cultivate the rice shoot of healthy growth: rice shoot survival rate is higher, rice shoot growing way is good.
To achieve the above object, the technical scheme adopted by the invention is as follows: a kind of breeding method of rice seedling successively wraps Include following steps:
S1) seed is subjected to exposure in the sun, impregnates seed with 30~40 DEG C of warm water after exposure, then carry out screen for seeds Choosing；The seed filtered out is immersed in thimerosal to carry out disinfection, is rinsed after disinfection with clear water；The thimerosal is that quality volume is dense The prochloraz aqueous solution that degree is 1.1%~1.8%, the thimerosal also include kuh-seng water extract and radix achyranthis bidentatae chrysanthemum water extract, Kuh-seng water extract and radix achyranthis bidentatae chrysanthemum water extract the summation mass percentage in the thimerosal are 6%~10%；
It S2 is) Paracetamol aqueous solution being immersed in 2~3d of seed-soaking liquid, the seed-soaking liquid by kind that step S1) is obtained, The seed-soaking liquid also includes yellow cinnamon leaf water extract, aloe water extract and alanine；
S3 vernalization) is carried out to the seed that step S2) is obtained, until seed breaks chest and shows money or valuables one carries unintentionally；
S4) seed broadcasting for obtaining step S3) carries out the cultivation of rice shoot on seedling bed.
In step S1), present invention improves over the formula of thimerosal, thimerosal is to contain kuh-seng water extract and radix achyranthis bidentatae chrysanthemum The prochloraz aqueous solution of water extract, when the mass-volume concentration of prochloraz aqueous solution is 1.1%~1.8%, and kuh-seng water is mentioned Taking object and radix achyranthis bidentatae chrysanthemum water extract the summation mass percentage in thimerosal is 6%~10%, has been surprisingly found that the thimerosal energy High-effective disinfecting is carried out to rice paddy seed；In step S2), present invention improves over the formula of seed-soaking liquid, seed-soaking liquid is to contain cinnamomum camphora The Paracetamol aqueous solution of leaf water extract, aloe water extract and alanine, can be in S1) step further sterilization later Disinfection seed, and nutritional ingredient required for germination can be provided for seed, improve plumule activity.
As an improvement of the above technical solution, the thimerosal is the prochloraz aqueous solution that mass-volume concentration is 1.6%, Kuh-seng water extract and radix achyranthis bidentatae chrysanthemum water extract the summation mass percentage in thimerosal are 7%；Pass through many experiments, discovery When the component of thimerosal uses above-mentioned content, the Disinfection Effect of seed is preferable.
As an improvement of the above technical solution, the seed-soaking liquid is the Paracetamol that mass-volume concentration is 1%~3% Aqueous solution, yellow cinnamon leaf water extract, mass percentage of the aloe water extract summation in seed-soaking liquid are 8%~13%；It is logical Many experiments are crossed, when finding the component of seed-soaking liquid using above-mentioned content, the Disinfection Effect of seed is more preferable, can preferably improve plumule Activity.
As a further improvement of the above technical scheme, the seed-soaking liquid is the acetylamino that mass-volume concentration is 2% Phenol aqueous solution.
Further improvement as above-mentioned technical proposal, the yellow cinnamon leaf water extract, aloe water extract summation exist Mass percentage in the seed-soaking liquid is 9%.
As an improvement of the above technical solution, in step S4), before seed broadcasting, one layer is also laid on seedling bed Nutrition Soil, the Nutrition Soil are made of the component of following mass fraction: 53~60 parts of peat soil, 10~20 parts of urea, sulfuric acid are sub- 4~7 parts and 4~8 parts of monkshood of iron.The present invention provides heat preservation, saturating on one side by being laid with one layer of Nutrition Soil on seedling bed for rice shoot The good environment of gas；On the other hand nutritional ingredient is provided for rice shoot, make rice shoot healthy growth: rice shoot survival rate is higher, rice shoot is long Gesture is good.
As a further improvement of the above technical scheme, the Nutrition Soil is made of the component of following mass fraction: peat 55 parts of soil, 14 parts of urea, 5 parts of ferrous sulfate and 5 parts of monkshood.
The beneficial effects of the present invention are: the present invention provides a kind of breeding method of rice seedling, and present invention improves over disappear The formula of venom, it is the prochloraz aqueous solution containing kuh-seng water extract and radix achyranthis bidentatae chrysanthemum water extract that thimerosal, which contains, is had been surprisingly found that The thimerosal can carry out high-effective disinfecting to rice paddy seed；Invention also improves the formula of seed-soaking liquid, seed-soaking liquid is to contain cinnamomum camphora Leaf water extract, aloe water extract and alanine have Paracetamol aqueous solution, then can be in S1) it is further after step Sterilizing, and nutritional ingredient required for germination can be provided for seed, improve plumule activity；The present invention is by seedling bed One layer of Nutrition Soil of upper laying, Nutrition Soil are the compound of peat soil, urea, ferrous sulfate and monkshood, and Nutrition Soil is rice shoot on one side Heat preservation, good environment of breathing freely are provided；On the other hand nutritional ingredient is provided for rice shoot, makes rice shoot healthy growth: rice shoot survival rate It is higher, rice shoot growing way is good.
