Abstract: A tea-picking experiment has been laid out both in pure tea garden and peachtea intercropping garden,for two summer seasons running at Linan and Fuyang Counties of Zhejiang Province which are located at north-mid subtropical area of China where the microclimate has been measured simultaneously.Results indicate that comparing with those in the pure tea plantation,in the peach-tea intercropping garden its light intensity,air temperature and wind speed reduced by l0 000～60 000 lx,0.3～2.1℃,and 0.1～0.3m·s-1 respectively but its air humidity increased by l%～5%.Working in the intercropping garden,the temperature of workers' clothes reduced by 0.5～1.5℃ while the most reduction appeared from those dressing in white and the workers' effective temperature and the most uncomfortable time during a day,the discomfort index and the most discomfortable time reduced by 0.3～0.8℃ and 2.5 hours,1～3 and l hour respectively.Due to the worker's comfortableness in the intercropping garden,the worker's productivity increases around 22.6%～29.5%.
