Container is sandwiched in the below of sugarcane stem by step 4., fills sulfurous acid solution;
Step 5. solution replacing construction and cut stem
Cut stem method: utilize shrub and hedge trimmer up to be cut off at 2cm place by sugarcane stem undercut;
Bloom before terminating, change a solution and cut stem every 2-3 days, bloom after terminating, flower of female parent fringe sugarcane stem was changed a solution every 4-5 days and is cut stem, and through after-ripening in 25-35 days, the moisture of recycling oven for drying seed, finally obtained hybrid seed;
Temperature and Humidity Control in step 6. greenhouse
Utilize Temperature and Humidity Control equipment that temperature should be remained on 26-28 DEG C, humid control is at 60-80%.
Preferably, step 2 sulfite solution is sulphur dioxide 6% aqueous solution, during use within half a year date of manufacture.
Compared with prior art, beneficial effect of the present invention is:
1. namely the sulfurous acid solution in the inventive method joins i.e. use, simple to operate, ensure that the freshness of solution.
2. the method for the invention is more cost-saving than tuns such as original barreleds, changes solution more convenient.
3. stem and Temperature and Humidity Control technology are cut in technical solution of the present invention cooperation, can improve foster stem effect and effectively spend fringe rate.
4. in specific implementation process of the present invention, the Sugarcane Breeding that some misses phimosis time or the not long root of phimosis can be made full use of, improve hybridization efficiency.
