甜菜叶子是甜菜制造营养物质的“天然工厂”,在第一年营养生长期间,叶片具有无限分化习性,所以甜菜叶片数量的多少和寿命的长短,虽受着遗传因素的制约,也受着自然条件的影响。因此,不同年份、不同地区、不同气候的栽培条件下,其叶片数量是不同的,寿命长短也是不一样的。本文仅就几年来对甜菜所调查的叶片数量进行分析。
Beet leaf is a “natural plant” for beet nutrition. During the first year of vegetative growth, the leaf has infinite differentiation habits. Therefore, the number of beet leaf and the length of its life span are controlled by genetic factors, Conditions of influence. Therefore, in different years, different regions and different climate cultivation conditions, the number of leaves is different, the length of life is not the same. This article only analyzes the number of leaves that beets surveyed in recent years.
