研究在 Banglabari T.E 地区进行,供试茶树60年生。试验期间没有雨水,气温为35—40℃,选择四种浓度的抗坏血酸溶液(10,20,25,30PPM)喷雾。每一处理(包括对照),重复十次。不同浓度抗坏血酸溶液在1976年8—9月间,每隔15天喷雾一次,对照的仅用清水。供试茶园在试前几个月曾受到过干旱的严重影响。全部试区在试验期间,采取特别措施控制病虫及杂草,因而茶树不会受任何其他因素所影响。同
The study was conducted in the Banglabari T.E region for 60 years of tea plant life. No rain during the experiment, the temperature was 35-40 ℃, the choice of four concentrations of ascorbic acid solution (10,20,25,30 PPM) spray. Each treatment (including control) is repeated ten times. Different concentrations of ascorbic acid solution in August-September 1976, spraying once every 15 days, the control of only water.
