| 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）。 |

| 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). |
