Trials with Lu Cotton No. 28 seed Chen dielectric sorting , separation of high voltage electrostatic and dielectric high voltage electrostatic composite processing , cotton seed germination rate was measured by the germination test , germination potential , seedling field test determination of the full-length , seedlings high , stem diameter , growth index and field emergence , to provide technical guidance to determine the cotton seed optimal processing program , guided by high yield and quality of cotton cultivation . The results show that : the different sorting Voltage (6000v, 7000v, 8000v) different drum speed (20 r / min, 25 r / min, 30 r / min) seed dielectric separation process , the germination rate , germination potential and field emergence there were significant differences , 7000V voltage 25r/min speed is optimal . Speed ??significantly affect seedling total length , height, stem diameter , and with the voltage increases , an increasing trend , 7000v voltage 25r/min speed conducive to to improve root diameter than nurturing seedlings . Considering to 7000v voltage 25r/min speed of processing . Different voltages (15 kV / m, 20kV / m, 25kV / m) processing time (20s, 40s, 80s) of high voltage electrostatic processing seed germination rate , germination potential and field emergence significant difference to 20 kV / m and 25 kV / m voltage processing 40s better . The processing time significantly affect seedling total length , height , stem diameter , 20 kV / m voltage processing 40s will help improve the root diameter than nurturing seedlings . Considering the 40s for the best treatment of 20 kV / m voltage processing , followed by the voltage of 25kV / m processing 40s . Voltage 7000v Select sorting speed 25r/min processing of seed , high voltage electrostatic 20kV / m and a 25kV / m processing time 40s combined treatment , tests completely experimental design , through the cottonseeds the germination test measurement germination rate , germination potential, measured by seedling field test seedlings full-length , height , stem diameter , growth index and field emergence , composite processing 20kV / m voltage for 40s better The 25kV / m voltage handling the 40s treatment had no significant effect . In summary , the dielectric separation , high-pressure the static can improve the germination rate , conducive to nurturing seedlings , sorting to of 25r/min speed dielectric 7000v voltage and 20 kV / m voltage processing 40s composite processing effect . Experimental results show that , after sorting dielectric and electric field treatment of seeds can improve vitality, promote the use of agricultural production .
