摘　　要：经研究认为，苹果“营养袋”快速育苗的关键技术为：采用通透性良好的蜂窝状营养袋，以肥沃壤土７３．５％，配以２５％的腐熟有机肥，加入１％的过磷酸钙及０．５％的尿素作为营养土，于２月１５日前后播入温床，培养砧木幼苗，于当年５月下旬在苗圃地进行带木质芽接。Our study shows that the key techniques of fast growing seedlings of apple with‘nutrition bags’are that the well ventilative honeycomb-like‘nutrition bags’ are adopted,which are filled With nutritious soil which contains 73.5% of fertile loam,25% of thoroughly decomposed organic fertilizer,1% of calcium superphosphate and of urea. The stock saplings are cultured in bags on the hotbed around Febeury 1.In the last ten days of May in the same year, buds with wood are grafted in the nursery.
