【摘要】 采用5种基肥，包括过磷酸钙（[P₂O₅]=12%,D）、广东林业科学研究院试验有机混合肥（N8P10K6,S）、挪威复合肥（N15N15K15,T）、混合复合肥（S:D=1:1, DS）、混合复合肥（S:T=1:1,TS）,5种等价量,即每种施放0元/株（CK）、0.3元/株、0.6元/株、0.9元/株、1.2元/株，随机区组排列，3个重复，每个重复21个处理，进行湿加松Pinus elliottii×P. caribaea基肥试验。结果表明：不同等价基肥量湿加松平均树高排序为：1.2元>0.6元>0.9元>0.3元>0元（CK）；不同施基肥处理湿加松平均树高排序为：DS>D>TS>T>S>CK；施不同基肥和量综合性状评定Pi值的变化范围为0.054 0～0.498 0，平均Pi值为0.336 1,20个处理都大于对照。Pi值最大的为DS4（0.6D:0.6S=1 042 g）,Pi值最小的为对照（无施基肥）。更多还原

【Abstract】 Five kinds of base fertilizer(including calcium superphosphate（[P₂O₅] = 12%, D）, Guangdong Academy of Forestry tests organic fertilizer（N8P10K6,S）, Norway compound fertilizer（N15N15K15, T）,compound fertilizer（S:D=1:1, SD）, and compound fertilizer（S:T=1:1, ST） and five kinds of equivalent amount,that is, each application of 0 yuan/plant（CK）, 0.3 yuan/plant, 0.6 yuan/plant, 0.9yuan/plant, 1.2 yuan/plant were randomly arranged in block groups, and 3 replicates were set up with 21 treatments per replicate to carry out base fertilizer application experiment. The results showed that the mean tree height of Pinus elliottii × P.caribaea was ranked as follows: 1.2 yuan > 0.6 yuan > 0.9 yuan > 0.3 yuan > 0 yuan（CK）. The mean tree height of different base fertilizer treatments was: DS > D > TS > T > S > CK. The variation range of Pi value was 0.054 0 ～ 0.498 0,the average Pi value was 0.336 1, and the 20 treatments were greater than the control. The maximum Pi value was DS4（0.6D: 0.6S = 1 042 g）, and the minimum Pi value was the control（no basal fertilizer）.更多还原
