STUDIES ON THE EFFECTS OF ARSENIC ON FARMLAND ECOSYSTEM
砷对农田生态系统污染效应的试验研究

The effects of arsenic on crops, soil organisms, soil animals and soil microbes in the farmland ecosystem are described in this paper. Pot experiments show that arsenic may affect the growth of crops obviously. The production of crops decreases as the concentration of arsenic in-creases. The seneitiv-ity of different crops to arsenic are different. Paddy rice is the most sensitive to is, spring wheats and maizes more sensitive. The effects of different states of arsenic are rot alike either. Ortho arsenite ...
