摘要：土壤硝态氮的淋失不但造成肥料的损失,而且产生严重的环境问题。对海南胶园土壤硝态氮分布规律进行研究,结果表明,海南植胶土壤硝态氮淋失量高。土壤硝态氮的分布与气候类型有很大相关。随着干燥程度的增加,0～100cm土层中硝态氮累积层从无到少,累积深度由深及浅。母质影响硝态氮的淋失,玄武岩母质发育的土壤硝态氮淋失风险小于其他母质,而其他母质之间差异不大。
Soil nitrate leaching not only causes the loss of fertilizer, but also brings about serious environmental problems. The distribution of soil nitrate in rubber plantations in Hainan was investigated. The results showed that the leaching loss of soil nitrate was high. The distribution of the soil nitrate was highly correlated with the types of climate. With an increase in dryness in climate, nitrate accumulation in the 0~100 cm soil layer was from zero to low, and from deep to surface layer. Parent material h...
