摘　　要：本文研究了不同播种密度对红花酢浆草生长和功能性状的影响。结果表明,红花酢浆草的生长和叶片功能性状均存在负密度制约现象,当播种密度达到150粒/m^(2)及以上时,负密度制约较强烈。本研究为酢浆草的防治和合理种植提供了一定的理论支持。The effects of different seeding densities on the growth and functional traits of Oxalis corymbosa were studied.The results showed that there was negative density constraint in the growth and functional traits of Oxalis corymbosa.When the seeding density reached 150 grains/m^(2)and above,the negative density constraint was stronger.This study provides some theoretical support for the control and rational planting of Oxalis corymbosa.
