【Abstract】 The relationship between fluoride pollution in mulberry leaves and the yield of silkworm cocoon has been established by the integral regression based analysis of the collected data on fluoride pollution monitoring and silkworm cocoon production in the past 17 years in the city of Huzhou, Zhejiang Province. The results indicated that the critical stage at which the cocoon yield per case of silkworm eggs will be affected by fluoride pollution in mulberry leaves is between the 3rd and 4th age when 1mg/kg fluoride increasing in mulberry leaves will lead to the cocoon yield reduction by 0 123 1～0 104 5 kg per case of silkworm eggs. Therefore, the effective reduction of fluoride in mulberry leaves at the silkworm rearing stage between the 3rd and 4th age should be considered as the control goal of fluoride pollution.更多还原
