【摘要】 <正>Allelopathic rice variety can release allelochemicals from roots to soil in which interfere with neighboring plant and microbial species,but little is currently known about their effect on enzyme activities of paddy soils.This study showed that enzyme activities and concentrations of allelochemicals in paddy field varied with rice varieties,growth stages and moisture regime.Allelopathic rice variety PI312777 paddy fields had higher更多还原
