本着理论联系实际,教学、生产、科研三结合的原则,我们于去年进行了湿地松火炬松引种育苗试验。苗圃选用坝区柑桔地四分,靠近水沟,行间翻耕,果、苗间种。土壤为冲积轻粘壤,PH7.0,层厚,肥润。以营养土袋、营养土床和一般苗床三种方式育苗进行比较。圃地用2%硫酸亚铁与可湿性六六六粉消毒,取松林土筛后加3%过磷酸钙装袋与铺筑苗床(厚10cm)。聚乙烯塑料袋长20cm,宽10cm,下部穿孔20个以利通气透
In the principle of combining theory with practice, teaching, production and scientific research, we carried out the experiment of seedling raising of Pinus elliottii in the last year. Nursery use citrus quarter dam area, near the ditch, between rows of tillage, fruit, seedling species. Soil alluvial light clay, PH7.0, layer thickness, fat. Nutritional soil bags, soil bed nutrition and seedbed in general three ways to compare. Garden with 2% ferrous sulfate and wettable six six six powder disinfection, take pine forest soil sieve plus 3% superphosphate bagging and paving seedbed (thickness 10cm). Polyethylene plastic bag length 20cm, width 10cm, the lower part of the hole 20 to facilitate ventilation
