摘　　要：现代科技的飞速发展,使得计算机模拟林木的生长成为可能,3-PG模型充分考虑了林龄、温度、盐分、空气湿度、土壤肥力和含水量、霜冻天数等因子对光合作用的影响,通过一系列方程模拟碳量平衡、水量平衡、盐分平衡和太阳辐射变化,以此来模拟林分的动态生长过程。3-PG模型应用于橡胶树栽培具备了各种软、硬件方面的条件,期望能在可行性评估、规划、定产、水分、养分、病虫害防治、割胶、绩效等方面,实现精准栽培。With the swift development of modem science and technology, people can simulate the growth of trees with computer. 3-PG growth model can simulate dynamic growth process of carbon, water and salt balance through full consideration of stand age, temperature, salt, atmospheric vapor, soil nutrition and water availability. 3-PG model has all the software and hardware conditions for accurate cultivation of Hevea brasiliensis in feasibility study, planning, production prediction, water, nutrient, diseases and pests control, tapping and performance.
