摘要
土壤改良剂(康乐)对草坪床土理化性质的影响研究表明,土壤改良剂(康乐)能降低土壤容重,提高土壤总孔隙度、渗透系数、田间持水量,丰富土壤有机质和全氮,调节速效养分,能有效降低土壤pH值和电导率。在试验范围内,随改良剂用量的增加,改良效果更明显。
The field experiment of effects of soil amendment(KANG LE) on soil properties was conducted.The results showed that soil bulk density decreased and soil porosity, permeability coefficient, field capacity increased under application of soil amendment. At the same time, after application of soil amendment, the content of organic matter and soil nutrition was higher than control, but soil pH and EC decreased. With increasing of amendment, the amended effects become more significant.
