1991年在浙北、浙西以及浙东的部份地方,枇杷遭受大雪低温危害,不仅幼果遭冻死胚,还使许多花穗冻烂,冬梢冻枯,老叶叶尖和叶缘冻焦。金华县傅村镇石狮塘村傅得响等来信询问:冬梢遭冻后有什么影响?应怎么办?现解答如下:一、冬梢遭冻后对枇杷的树势和结果有无影响?枇杷与其它果树不同,有春、夏、秋、冬四季梢。而冬梢因气温的高低变化,时长时停,直至开春后,继续延伸而成为春梢。这些春梢,在4月上旬前渐趋老熟,被称为“早春梢”。枇杷是以夏梢为主要结果母枝。凡是冬梢延伸成的早春梢,能在7月上旬以前萌发健壮的夏梢。因萌发时间早,生长充实,花芽分化良好,是丰产的甚础。又冬梢多为枝条的顶芽,因而冬梢遭
In parts of northern Zhejiang, western Zhejiang and eastern Zhejiang in 1991, loquat suffered from heavy snow and low temperature. Not only the young fruits were frozen and died embryos, but also many rotten flowers were rotten, the shoots were freeze-dried, the tip of old leaves and leaf margin Frozen coke. Fuxin, Fucun Town, Jinhua County, Fu De ring and other letters asked: What are the effects of winter tips after being frozen? What should I do? Answer is as follows: First, the winter tips after the cold on the loquat tree and the results have no effect? Loquat and other Different fruit trees, spring, summer, autumn and winter four-season shoots. The winter tip due to changes in the level of temperature, when stopped for a long time, until after the spring, continue to stretch and become spring shoots. These spring shoots, getting more mature before the first ten days of April, are called “early spring shoots.” Loquat summer root is the main result of the mother. All winter shoots extended into the early spring shoots, in early July germination before the robust summer shoots. Because germination time early, full growth, flower bud differentiation well, is a very rich basis. Winter shoots and more for the top branches of shoots, and therefore winter shoot was
