山东省茶园总面积1.01万hm2,去冬发生了较大冻害,根据冻害后在日照、青岛、临沂三市10个县(市)调查结果,全省春茶减产约27.93万kg,减产春茶35%。通过冻害因素分析可知,土壤含水量低,冻土深度加厚及管理水平低均与冻害呈正相关。并提出了冻害后技术措施,提高茶园冻害后的经济效益。
According to the survey results of 10 counties (cities) in three cities of Rizhao, Qingdao and Linyi, the province’s spring tea production decreased by 279,300 kg and the output of spring tea 35%. Through the frost damage analysis, we can see that the soil moisture is low, permafrost depth and low management level are positively correlated with frost damage. And put forward the technical measures after frost damage to improve the economic benefits of tea plantation after frost damage.
