采用Logistic方程模拟，揭示了沙棘（Hippophae rhamnoides）、刺槐（Robinia Pseudoacecia）、山杏（Prumus armeniaca）等10个树种的生长发育特性．以试验数据分析了造林密度、施肥、平茬与灌木林产量的密切关系．
Logistic equation simulation was used to reveal the growth and development characteristics of 10 species of Hippophae rhamnoides, Robinia pseudoacacia and Prumus armeniaca. Based on the experimental data, the close relationship between plantation density, fertilization, stubble and shrub yield was analyzed.
