秋季造林就是指树木落叶(针叶树地上生长停止)到土壤结冻前这段时间的造林。造林必须坚持“适地适树”原则,即造林地的立地条件要适合树种的生态要求;树种的生态要求适合造林地的立地条件。立地条件中除了土壤、地形以外,气候条件也是个主要因子,即造林季节必须满足种子,苗木或插条的发芽,根系再生或不定根形成的生理要求;
Fall afforestation refers to the deciduous trees (conifers growth stops) to the soil before freezing this period of afforestation. Afforestation must adhere to the principle of “Appropriately Adapt to Trees”, that is, the site conditions of afforestation land should be suitable for the ecological requirements of tree species; the ecological requirements of tree species should be suitable for site conditions of afforestation land. In addition to the soil and topography, the climatic conditions are also a major factor in the site conditions. That is, the afforestation season must meet the physiological requirements for germination of seedlings, seedlings or cuttings, regeneration of root systems or adventitious root formation.
