通常所说的冻害,有秋冬甘蔗成熟季节的冻害,也有越冬的宿根蔗地下芽的冻害,也有窖藏甘蔗种苗的冻害。成熟季节的冻害,习惯称“霜冻”。当绝对最低气温在0℃或0℃以下时,重霜伴随着冰冻使甘蔗部份组织或整株丧失生活力,或失去部份生理功能。霜冻对甘蔗造成糖份水解,制糖困难。蔗芽受冻坏后,影响留种,所以霜冻是甘蔗生产上不可忽视的问题。1975～79年,笔者曾对甘蔗霜冻作过初步的调查,现整理如下。
Commonly referred to as frost damage, there are autumn and winter frost damage in sugar cane ripening season, there are winter frog damage to the underground shoots of ratoon sugarcane, there are cellar sugar cane seedlings frost damage. Frost damage in the mature season, used to call “frost ”. When the absolute minimum temperature below 0 ℃ or below 0 ℃, heavy frost along with frozen some of sugarcane tissue or whole plant loss of viability, or loss of some physiological functions. Frost on sugar cane sugar hydrolysis, sugar difficulties. After the frost is damaged, the sugarcane will affect the remaining species, so the frost is a problem that can not be ignored in the production of sugar cane. From 1975 to 1979, I had a preliminary investigation of sugar cane frost, are now organized as follows.
