1小麦冻害的类型初冬冻害初冬冻害一般由骤然强降温引起。11月中下旬-12月中旬,最低气温骤降10℃左右,达-10℃以下,持续2～3天,小麦的幼苗未经过抗寒性锻炼,抗冻能力较差,极易形成初冬冻害。壮苗一般不会造成冻害,最多造成叶尖受冻,对小麦的生长和产
A type of frost damage in early winter Frost damage Early winter frost damage is generally caused by sudden strong cooling. From the middle of November to the middle of December-December, the minimum temperature plunges about 10 ℃ and reaches below -10 ℃ for 2 ~ 3 days. The seedlings of wheat have not been subjected to the cold-resistance exercise and have poor frost-resistance ability, . Strong seedlings generally do not cause frost damage, causing the tip of the most frozen, the growth and production of wheat
