一、试验的目的和意义:气孔是高等植物与周围大气不断地进行气体交换和水分散失的主要门户,它的开闭与植物的光合作用,呼吸作用和蒸腾作用等生理功能有密切的关系,从气孔开闭的规律可以了解茶树的生物学特性;综合生态因子及栽培技术对茶树的适宜情况。本试验要求达到以下的目的:1、探求茶树在夏季正常气候条件下,茶树气孔开闭的规律;

First, the purpose and significance of the experiment: Stomata is the main portal for higher plants and the surrounding atmosphere to continue gas exchange and water loss, its opening and closing and plant photosynthesis, respiration and transpiration and other physiological functions are closely related, From the stomatal opening and closing of the law can understand the biological characteristics of tea; comprehensive ecological factors and cultivation techniques of tea suitable situation. The test required to achieve the following objectives: 1, to explore the law of tea tree stomata opening and closing under the normal summer conditions;
