摘要

通过人工控制试验法测定了马铃薯冻害等级冠层温度指标.结果表明:马铃薯0级冻害(无冻)温度指标为冠层温度＞-3.0℃;1级冻害(轻冻)温度指标为冠层温度(-3.5℃,-3.0℃];2级冻害(中冻)温度指标为冠层温度(-4.5℃,-3.5℃];3级冻害(重冻)温度指标为冠层温度(-5.5℃,-4.5℃];4级冻害(严重冻)温度指标为冠层温度≤-5.5℃.

Abstract

In this paper,the canopy temperature index of potato frost damage grade was determined by artificial control experimen-tal method.The results showed that the temperature index of grade 0 frost damage(no freezing)was canopy temperature greater than-3.0℃,the temperature index of grade 1 frost injury(light freezing)was that the canopy temperature was lower than or equal to-3.0℃and higher than-3.5℃,the temperature index of grade 2 frost damage(medium freezing)was canopy temperature less than or equal to-3.5℃and higher than-4.5℃,the temperature index of grade 3 frost damage(heavy freezing)was that the canopy tem-perature was lower than or equal to-4.5℃and higher than-5.5℃,and the temperature index of grade 4 frost damage(severe freez-ing)was that the canopy temperature was lower than or equal to-5.5℃.
