Abstract:
Taking radish ‘Weixian’ as experimental material,different concentrations of Uniconazole(S3307),Abscisic Acid(ABA),Maleic hydrazide(MH) and Chlorcholinchlorid (CCC) four kinds of plant growth regulators were sprayed on seedlings at trefoil stage to explore the inhibition effects of plant growth regulators on bolting of anti-season radish cultivation.In this experiment, the budding rate,the bolting rate and changes of C/N ratio were investigated.The results showed that compared with the control, four kinds of plant growth regulators, four days of spraying time and a total of four times,made seedlings dwarf and strong in various concentrations.The treatment of S3307,ABA,MH and CCC led to radish bolting rate descending 421%,141%,906%,237% respectively, in which the treatment of MH severely inhibited plant growth.The treatment of Uniconazole 600 mg/L decreased the radish leaf C/N ratio to 802%,effectively reduced the budding rate and the bolting rate (decreased by 673%,598%) of plants, it was suitable for spring anti-season radish cultivation and relieve the budding process.
