茶树原是生长在我国西南大森林底下的植物,喜漫射光线、湿润、温暖的气候条件,在诸因子中,光对茶树,特别是幼年茶树影响很大。光是热量的来源,使空气温度升高,使空气湿度降低,而空气中水汽密度的增加,能使光照减弱。我场八二年春拓植的二块直播茶园,一块是彭介山,面积2.5亩;另一块是孙介弄,面积是1.2亩,由于环境影响了光照,产生不同热量,在年生长量上表现出明显的差异。孙介弄茶园,南面有灵岩山阻挡着太湖来的水汽,夏秋季,强烈的西射光照在幼苗上,则地温上升,叶温增高,气孔关闭,妨碍正常的生理活动,严重影响生长,所以茶苗矮小,年生长量不到20cm。
Tea tree is the original growth of plants in China under the big forests of the Southwest, hi diffuse light, moist, warm climatic conditions, among various factors, the light of tea, especially young tea tree greatly affected. Light is the source of heat, so that air temperature increases, so that air humidity decreases, while the air vapor density increases, can make the light weakened. In the spring of August 1982, two direct-seeding tea gardens were planted. One was Peng Jieshan with an area of 2.5 mu. The other was Sun Jieong with an area of 1.2 mu. As the environment affected the light and produced different amounts of heat, it showed an annual growth rate Significant differences. Sun Kai get tea, south of Lingyan blocked the water vapor coming from Taihu Lake, summer and autumn, the strong West shot light on the seedlings, the ground temperature rise, increased leaf temperature, stomatal closure, hinder normal physiological activity, seriously affect the growth, so Short tea seedlings, the annual growth of less than 20cm.
