摘　　要：　在橘园种植豆科牧草罗顿豆,研究其对橘园土壤水分、地温、土壤肥力的影响。结果表明,在高温干旱期种植牧草罗顿豆处理的土壤水分含量平均提高了5.3%,地表温度降低了9.98℃(2003-08-09观测值);种植牧草罗顿豆能改良土壤,培肥地力,其中土壤有机质提高19.5%,全P提高34.5%,速效N提高13.2%,速效K提高16.11%,且达显著差异水平。Ecological effect of planting Lotononis in orchard was studied.The result showed that the treatment of planting forage Lotononis could enhance 5.3% soil moisture content in average,soil surface temperature could decrease 9.98 ℃ (08-09 observation) in hot period;planting forage Lotononis could improve soil fertility,soil organic matter increases 19.5%,total P increases 34.5%,available N increases (13.2%),available K increases 16.11% and show significant difference.
