摘要：对江西省永丰县官山林场4种施肥处理(45%矿渣肥、39%矿渣肥、毛竹专用肥和对照)毛竹地上部分营养器官N、P、K养分含量及其随年龄增加的变化规律和养分积累、空间分配规律进行研究。结果表明,施肥对毛竹地上器官NPK含量和养分积累具有明显影响。3种施肥处理均能显著提高毛竹地上器官的平均NP含量,毛竹专用肥处理毛竹地上器官平均K含量显著大于对照,而矿渣肥处理毛竹地上器官平均K含量显著小于对照,可能是由于矿渣肥K素配比较低导致;不同器官中,45%矿渣肥处理N含量及各施肥处理K含量在毛竹地上器官中总体表现为叶>秆>枝,其余各处理地上器官NP含量均表现为叶>枝>秆,各营养元素含量大小顺序为N>K>P;矿渣肥处理中N元素积累量最高,毛竹专用肥和对照中K元素积累量最高,均以P元素积累量最低;施肥能够有效提高竹林地上器官对NPK养分含量的积累,N元素积累量为45%矿渣肥>39%矿渣肥>毛竹专用肥>对照;P元素积累量为45%矿渣肥>毛竹专用肥>39%矿渣肥>对照;K元素积累量为毛竹专用肥>45%矿渣肥>39矿渣肥>对照;总积累量为45%矿渣肥>毛竹专用肥>39%矿渣肥>对照。矿渣肥提高了枝营养元素分配比例,毛竹专用肥提高了叶营养元素分配比例。由此可见不同肥料对毛竹生长影响不同,应根据立地条件和经营目标合理选择肥料。
Phyllostachy edulis plays an important role in forestry production in China. The concentration of nutrient elements is one of important parameters to reveal the process of nutrient cycling in the ecological system. The concentrations and accumulation of NPK in above ground organs of P. edulis after being applied with differ- ent fertilizers （45% slag fertilizer, 39% slag fertilizer, special fertilizer for P. edulis） were analyzed in Guanshan Forest Farm, Yongfeng County, Jiangxi Province. The results showed that fertilization had an obvious effect on NPK content and nutrient accumulation in vegetation organs of bamboo. Fertilizations improved the average con- tent of NP, special fertilizer for bamboo treatment improved the average content of P, while slag fertilizer treat- ment decreased the K content because slag fertilizers contain a very low level of K. N content in 45% slag fertil- izer and K content in all treatments showed a trend of leaf〉 branch〉 culm, while the nutrient content in the same organ showed the order of N〉K〉E The nutrient content showed a decrease trend with the increasing age. The ac- cumulation of N was highest in slag fertilizer treatment, and the accumulation of K was highest in special fertilizer treatment and CK. Fertilization can improve the accumulation of NPK. The accumulation of NPK in organs above ground follows a decreasing order： N, 45% slag fertilizer〉39% slag fertilizer〉Special fertilizer for bamboo〉CK; P, 45% slag fertilizer〉Special fertilizer for bamboo〉39% slag fertilizer〉CK; and K, Special fertilizer for bam- boo〉45% slag fertilizer〉39% slag fertilizer〉CK. The total accumulation of nutrients showed the trend of 45% slag fertilizer〉Special fertilizer for bamboo〉39% slag fertilizer〉CK. Meanwhile, slag fertilizer and special fertil- izer could increase the proportion of nutrient content in the branch and leaf, respectively. Therefore, different fer- tilizers had different influences on the growth of bamboo, and the site condition and management objectives should be considered in fertilizer selection.
