本文重点在于解决大行山区侧柏营养袋育苗的容器规格和营养土配方选择问题。试验结果表明：中等规格（５．７×１４ｃｍ）的容器，有利于苗木生长发育，在造林中应广泛使用。小规格容器（３．８－５．１×１２ｃｍ），适宜造林地较远、运输不方便的地区。在羊粪较充足的地区，营养土以羊粪３０％＋土杂肥３０％＋复合肥０．２％＋黄心土３９．８％最合理。
This article focuses on the solution to cultivate seedlings of oriental arborvitae nutrition bags in Daxing mountainous area and the selection of nutritional soil formula. The test results show that the container of medium size (5.7 × 14cm) is conducive to the growth of seedlings and should be widely used in afforestation. Small size containers (3.8-5.1 × 12cm), suitable for afforestation far, transportation inconvenient areas. In the area where sheep manure is more abundant, it is most reasonable to use nutrient manure as 30% sheep manure + 30% manure fertilizer + 0.2% compound fertilizer + 39.8% yellow heart soil.
