| 中文摘要: |
| 对武定县2019年引种湿加松造林地块进行样地监测调查，分析海拔、土层厚度、整地方式、经营管理措施对湿加松树高和胸径的影响。结果表明：湿加松适宜在海拔1 800~2 300 m的温凉坝区和云南松原生分布区种植；中厚层土壤、阳坡、缓坡有利于湿加松生长；机械全垦，布设70 cm×70 cm×60 cm以上规格种植塘，基肥施入农家肥和复合肥，湿加松速生丰产杂交优势明显；造林后全面封禁，适时松土、除草、抹蘖，幼树生长健壮。 |
| 英文摘要: |
| A sample plot survey and analysis were conducted on the introduction of Pinus elliottii×P.caribaea in Wuding County in 2019. The altitude, soil layer thickness, land preparation methods, and management had a significant impact on the height and DBH of Pinus elliottii×P.caribaea. The results showed that Pinus elliottii×P.caribaea was suitable for planting in the warm and cool dam area at an altitude of 1 800~2 300 meters and the original distribution area of Pinus yunnanensis; medium thick soil layer, sunny slopes, and gentle slopes were beneficial for the growth of Pinus elliottii×P.caribaea; mechanical reclamation, deployment of planting ponds over the size of 70 cm×70 cm×60 cm, and applying base fertilizer to farm manure and compound fertilizer, had a significant hybrid advantage in quick growth and high yield of Pinus elliottii×P.caribaea; comprehensive ban after afforestation and timely ripping, weeding, and tiller cutting were beneficial for the growth and health of young trees. |
