摘　　要：为探明连续不同配方施肥对马尾松林生长的影响及其肥料效应,并筛选适宜施肥处理。以8年生马尾松人工林为研究对象,采用完全随机区组设计进行了为期3年的连续施肥试验,设置氮肥(T1)、磷肥(T2)、氮磷钾肥(T3)、氮磷钾肥+微肥+石灰(T4)、有机无机复混+微肥+石灰(T5)和不施肥(CK)6个处理,基于连续3年生长测定数据,分析比较不同施肥处理的肥料效应。结果表明:连续施肥能显著提高马尾松林生长量,尤其T5处理的增产效果最好。T4处理对胸径生长量影响最大,与施肥前相比分别增加2.27 cm、3.21 cm、3.77 cm较CK增长量提高75.9%、80.3%、72.1%;对于树高生长量影响第1年以T1处理最大,与施肥前对比增加1.22 m较CK增长量提高110%,第2年以T5处理最大,与施肥前相比分别增加3.02 m较CK增长量提高52.5%,第3年以T2处理最大较CK增长量提高23.8%;对于单株材积的影响T5处理最大,与施肥前相比分别增加0.036 m3、0.070 m3、0.090 m3较CK增长量提高112.0%、75.0%、69.8%。马尾松蓄积增长量的基础地力贡献率随时间延长T1、T3、T4、T5、CK均呈现先降低后增加的趋势,肥料贡献率与之相反。而T2处理呈现持续降低的趋势。施肥后第2、3年马尾松蓄积增长量的稳定性和可持续性长期施肥处理显著高于CK,其中T4处理最高,但与T5处理差异不显著。综上,施加有机无机复混肥+微肥+石灰处理对于马尾松林生长增产显著,且肥料持续性较高。In order to explore the effect of continuous fertilization of different formulas on the growth of Pinus massoniana Lamb forest and its fertilizer effect,and to screen suitable fertilization treatment,This study takes the 8-year-old Pinus massoniana Lamb plantation as the research object,and uses a completely random zone design to carry out a three-year continuous fertilization test,setting up nitrogen fertilizer(T1),phosphorus fertilizer(T2),nitrogen phosphorus potassium fertilizer(T3),nitrogen phosphorus potassium fertilizer+micro fertilizer+lime(T4),organic inorganic compound+micro fertilizer+lime(T5)and no fertilizer(CK).Based on the growth measurement data for 3 consecutive years,the fertilizer effects of different fertilization treatments are analyzed and compared.The results show that continuous fertilization can significantly increase the growth of Pinus massoniana Lamb forest,especially the T5 treatment has the best effect of increasing yield.T4 treatment has the greatest impact on the growth of chest diameter.Compared with before fertilization,the increase is 2.27cm,3.21cm and 3.77 cm respectively.Compared with CK,the growth rate is 75.9%,80.3%and 72.1%.For the high growth of trees,T1 treatment is the largest in the first year.The increase is 1.22 m compared with CK increased by 110%before fertilizer.In the second year,it was treated with T5,with the largest.Compared with before fertilization,it increased by 3.02 m.Compared with before fertilization,the growth rate of CK increased by 52.5%.In the third year,the maximum growth rate of T2 was increased by 23.8%compared with CK;for single plants,T5 treatment is the most affected by the salum,with an increase of 0.036 m 3,0.070 m 3 and 0.090 m 3 compared with before fertilization.Compared with CK growth of 112.0%,75.0%and 69.8%respectively,the basic ground contribution rate of Pinus massoniana Lamb accumulation growth increases over time.T1,T3,T4,T5 and CK all show a trend of decreasing first and then increasing.The fertilizer contribution rate is opposite,a
