| 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。 |

| Abstract: |
| 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. |
