以宁夏灵武长枣和中宁圆枣1年生休眠枝条为试材,经低温处理后,测定电导率,经Logistic方程计算,结果表明:其抗寒半致死温度度分别为-33.58℃、-34.44℃。抗寒能力中宁圆枣>灵武长枣。
The results showed that the semi-lethal temperatures of cold-tolerant plants were -33.58 ℃ and -33.58 ℃, respectively. The results showed that the semi-lethal temperatures of cold- 34.44 ° C. Cold-resistant jujube> Lingwu long jujube.
