茶园灌溉是如何进行的

茶园灌溉时期: 茶园灌溉的效果高低,虽然与灌水次数与灌溉水量有关,但更重要的还要看是否适时,也就是说要掌握好灌水的火候。我国茶农历来对灌溉有“三看”的经验:一看天气是否有旱情出现,或已有旱象,是否有发展趋势;二看泥土干燥缺水的程度;三看茶树芽叶生长与叶片形态是否缺水。现在人们已在“三看”经验的基础上制定了茶园灌溉的技术指标,进行综合分析,从而科学地确定茶园灌溉的适宜时期。 茶园灌溉的生理指标 茶树水分生理指标能在不同的土壤、气候等生态环境下直接反映出体内水分的实际水平。例如细胞液浓度,新梢叶水势(可用兆帕斯卡Mpa表示)等对外界水分供应很敏感,与土壤含水量和空气温湿度之间具有较高的相关性。如果上午9时前测定,细胞液浓度低于8~9%,叶水势高于-0.5Mpa,表明茶树树体内水分供应较正常,若细胞液浓度达到10%左右,叶水势低于-1.0Mpa,表明树体水分亏缺,新梢生育将 ...
