Application of chemical methods on frost disaster prevention
化学调控技术的防霜应用研究

It is known that accelerating maturation and shortenin g growth cycle of crops may escape from the damage by early frost disaster. In thi s study, aimed at the vulnerability of ordinary techniques in frost prevention, different types of chemical regulators are tested to validate their effects on c rop growth. The results show that the regulators have more effective both on promoting crop growth rate and shortening crop growing cycle, and furthe rmore increasing its yield. It proves to be very significant for alleviating the damage from frost disaster by using chemical regulating methods, and especially it is wor thwhile for further research.
