湿地松硬质容器育苗技术研究

Study on Seedling Cultivation Technique of Pinus elliottii with Rigid Plastic Container

采用锯木屑、菌菇堆肥细料作介质，配制成５种不同配方混合基质，进行湿地松硬质容器育苗试验。结果表明：①配方Ｅ（菌根土１７％＋腐熟栏肥１０％＋过磷酸钙３％＋锯木屑１０％＋菌菇堆肥细料５％＋河沙１０％）为较理想的基质②基质能较好地满足湿地松容器苗的生长，高生长为对照的１６８．８３％③能降低容器苗的重量，为对照的２６．９％～６６．６７％，便于运输④基质的价格低廉，为５元／５０ｋｇ。

Seedling cultivation experiment of Pious elliottii in rigid plastic container with five different formulas compound substrate mixed by sawdust, mushroon-manure etc. showed that the optimal was formula E: fungus root soil 17% + barnyard manure 10% +calcium superphosphate 3% + sawdust 10% + mushroom-manure 50% + sand 10% .The compound substracte could satisfy increment of container Pinus elliottii seedling,height increment was 168.83% of the control and meantime,its weight was only 26.9%￣66.67% of the control. The compound substrate costed only 5 yuan per 50 kg.
