- 摘要:
- 霜冻危害是梨树生产中常见的自然灾害之一,发生频繁,生产损失大。因此,如何科学的预防防霜,减轻生产损失,是梨树栽培者和研究者共同关心的问题。现通过对梨树霜冻的特点、临界温度、地理和气象因素分析,结合多年来梨园生产实践经验,提出了梨树春季晚霜冻害预防技术措施,以期为梨树生产提供技术参考依据。
- Abstract:
- The frost injury is one of the common natural disasters happened frequently in the pear production,and it would cause the production loss.Therefore,how to scientific prevention frost injury,reduce the production loss,is the problem of common concern of pear planter and researcher.Based on the analysis of characteristics of pear frost injury,critical temperature,geographical and meteorological factors,and the production practice,the prevention techniques of frost injury in the pear orchard were introduced.The purpose was to provide technical reference for the pear production.
