前言茶树为多年生常绿叶用饮料作物,其越冬枝叶及液间孕育着的茶芽所组成的光合叶面积和枝叶中所含有机养分,乃翌年春梢形成的代谢源。据Hzdtupob(1980年)研究,上年留下的老枝叶提供了当年光合产物总量的58.9～75.1％,当年各季留养的叶片只占22.5～37.9％,由此可知,当年茶叶产量的物质基础主要是越冬枝叶,生产上还通常用来予测茶叶丰歉的依据。
Foreword Tea tree is a perennial evergreen leaf with beverage crops, the winter leaves and liquid tea buds formed by the composition of the photosynthetic leaf area and organic nutrients contained in foliage, the formation of the next spring shoot metabolic source. According to the study of Hzdtupob (1980), the old leaves left over the previous year provided 58.9-75.1% of the total photosynthetic products of that year, leaving only 22.5-37.9% of the leaves left in all seasons, indicating that the output of tea The material basis is mainly winter branches and leaves, the production is often used to determine the basis for apologizing for tea.
