材料和方法本研究于1975年在印度台拉登林业研究所营林试验苗圃进行。试验设8种处理:T_1——对照;T_2——75%五氯硝基苯可湿粉;T_3——45—75%代森锰锌可湿粉;T_4——75—78.6%代森锌粉;T_5——50%氯氧化铜扮;T_6——75%四甲基二硫化物杀菌剂;T_7——Zincop;T_8——升汞。试验种子为卵果松(Pinus oocarpa),湿地松(P.elliottii),洪都拉斯加勒比松(P.caribaea Var.hondurensis)和展叶松(P.patula)。试验随机排列,4次重复。每一树种50粒种子播在5×50×20厘米的发芽箱内。试验土壤是混合土,即一份菌根土,三份河砂。菌根土采自印度长叶松(P.roxburghii)林地(粘土,含碳1.68%,氮0.19%,氧化钾0.42%,五氧化二磷0.046%,水59.31%,pH值6.1),河砂pH值8.6.
Materials and Methods The study was conducted in 1975 at the Nursery Tillage of Taiwan’s Laden Institute of Forestry. Test set 8 kinds of treatment: T_1 - control; T_2 - 75% Pentachloronitrobenzene wettable powder; T_3 - 45-75% mancozeb wettable powder; T_4--75-78.6% Powder; T_5 - 50% copper oxide oxide play; T_6 - 75% tetramethyl disulfide fungicide; T_7 - Zincop; T_8 - mercuric chloride. The test seeds were Pinus oocarpa, P. elliottii, P. caribaea Var. Sinensis and P. patula. The experiments were randomized and repeated 4 times. Fifty seeds of each species were sown in a germination box of 5 × 50 × 20 cm. The test soil is a mixture of soil, ie, one mycorrhizal soil and three river sand. Mycorrhizal soil was collected from P. roxburghii forest land (clay, 1.68% carbon, 0.19% nitrogen, 0.42% potassium oxide, 0.046% potassium phosphate, 59.31% water, pH 6.1) pH 8.6.
