摘要: :基于枇杷山坡地梯度观测资料和幼果低温箱试验分析,对枇杷低温冻害等级指标进行初步研究。建立了基于日最低气温的枇杷低温冻害等级指标,轻度冻害:-2.5℃Abstract: Based on the data of gradient observation in hillside land of loquat and analysis of an experiment on young fruits harmed in low-temperature box,the grade index of freezing injury of loquat was preliminarily studied. The grade index of freezing injury of loquat was established on the basis of the daily extremely low temperature, that is: the mild freezing injury was -2.5℃< Tmin≤-1.0℃; the moderate freezing injury was -3.5℃
