一、前言茶树是多年生木本植物,就采摘茶园来说,一年中采摘次数多,要求新梢生长旺盛,就应不断地供应养分,因而在采摘茶园中追施肥料是很重要的。对一年生茶园来说,茶苗在个体发育过程中,除种子萌芽初期由子叶供给所需的营养外,主要是地下部通过根系吸收土壤中的水分和无机盐类。地上部依靠叶子通过光合作用制造碳水化合物。研究一年生幼苗平均每株需氮量的极大限度,探讨每亩追肥量对茶苗增长效应的理论数据,将是一项值得深入研究的工作。
First, the foreword Tea tree is a perennial woody plant, picking tea plantations, the number of picking a year and require new shoots strong growth, it should continue to supply nutrients, so in the pick tea plantation fertilizer is very important. For an annual tea plantation, tea seedlings in the process of individual development, in addition to early seed germination by cotyledons supply the required nutrients, mainly through the roots of underground parts of the soil to absorb moisture and inorganic salts. The shoots rely on leaves to make carbohydrates by photosynthesis. Studying the maximum per unit nitrogen requirement for annual seedlings, and discussing the theoretical data about the effect of dressing per hectare on the growth of tea seedlings will be a worthwhile study.
