本文对落叶松人工林第二代效应进行了阶段性研究，大扁杏作为更新树种成活和长势与山地阔叶林皆伐迹地无差异，在四平市山地（森林草原气候）可以正常生长，并能结实，生长节律完整。通过大扁杏的栽植研究了一项不用浇水的简捷实用技术，即秋季挖坑并回填土、春季醮吸水剂缝植。这项技术为果树栽植提供了新的技术，解决了取水难的问题。
In this paper, the second-generation effects of Larch plantation were studied in stages. The survival and growth of Daphniphyllum as a newer species were indistinguishable from those of the broad-leaved forest in mountainous area, and could grow normally in the mountainous area of Siping City Can be strong, growth rhythm complete. A simple and practical technique that does not require watering has been studied through the cultivation of Machado apricot, that is, pit digging and backfilling in autumn and seeding of water absorbent in spring. This technology provides new technology for fruit tree planting and solves the problem of difficult water intake.
