摘要
在河西走廊东部,冬枣可以正常生长,但受霜冻影响,不能正常落叶;其开花时间、座果时间和果实变色时间均较民勤小枣和鸣山大枣迟,果实的生育期相对较长,耐霜冻,果实的含糖量较其原产地高;果实较民勤小枣和鸣山大枣脆,但风味较后者淡。冬枣果实在10月上中旬才完熟,早霜期在9月中旬的河西走廊应谨慎种植。
Dongzao can grow in east of Hexi Corridor, but cannot defoliate normally because of the influences of frost. Its times of abloom, fruiting and turning colors of fruit are later to compare with that of Minqin Xiaozao and Mingshan Dazao, the procreating time of fruit is relatively longer, and resistant frost, with more sugar to compare with that of original area, but the fruit is crisper and with lighter flavor to compare with that of Minqin Xiaozao and Mingshan Dazao. The fruit of Dongzao will ripe fully in early and middle October, and it should be cultivated discreetly in Hexi Corridor with an early frost in middle September.
