| 摘 要： | 在闽北开展雷竹施肥试验，设置4种施肥处理：不施肥对照(处理1)，施用氮磷钾复合肥(375kg/667m2，处理2)，施用有机肥(腐熟的鸡粪5t/667m2，处理3)，施用有机肥与氮磷钾复合肥(腐熟的鸡粪3t/667m2和氮磷钾复合肥150kg/667m2，处理4)，分析不同施肥处理对雷竹叶片光合色素含量、光合特性、竹林生长、笋产量和品质等的影响，筛选出适合闽北雷竹经营的优化施肥方案。结果表明：不同施肥处理对雷竹叶片光合色素含量的影响未达到显著差异水平，但对竹林的光合特性、生长量、笋产量和笋营养物质含量均产生显著性差异影响；光合特性指标表现最优的是处理3和处理4，竹林生长效果最好的为处理2和处理4，竹笋产量和笋品质表现最优的是处理4和处理3。综合分析认为，最优施肥方案为处理4，即施用有机肥(腐熟的鸡粪)3t/667m2+氮磷钾复合肥150kg/667m2，该施肥处理可有效提升雷竹光合作用效率、促进竹林生长、增加竹笋产量及提高竹笋营养价值。

| Abstract: | The fertilization experiment is carried out at Phyllostachys praecox forest in the north of Fujian Province. Four fertilization treatments are designed, including non-fertilized control (Treatment 1), fertilized with NPK compound fertilizer (375 kg/667 m2) (treatment 2), fertilized with organic fertilizer (rotting chicken manure, 5 t/667 m2)(treatment 3), and fertilized with organic fertilizer (rotting chicken manure, 3 t/667 m2) + NPK compound fertilizer (150 kg/667 m2)(Treatment 4), to analysis the effects of different fertilization treatments on photosynthetic pigment content, photosynthetic characteristics, bamboo growth, shoot yield and quality of P.praecox and screen out the optimized fertilization scheme suitable for the management of P.praecox in North Fujian. The results show that the effects of different fertilization treatments on photosynthetic pigment contents of P.praecox are not significantly different, while the effects on the photosynthetic characteristics, bamboo growth, shoot yield and nutrient content in shoot are significant different. Treatments 3 and 4 have the best performance in photosynthetic characteristics, treatments 2 and 4 have the greatest effects on bamboo growth, and treatments 4 and 3 have the best effects on the yield and quality of shoots. Based on the above analysis, it is found that treatment 4 is the optimal fertilization scheme, i.e., applying organic fertilizer (rotting chicken manure) (3 t/667 m2) + NPK compound fertilizer (150 kg/667 m2), which can effectively enhance the photosynthetic efficiency, facilitate the growth of bamboo forest, increase the yield of bamboo shoots and improve the nutritional value of bamboo shoot. |
