摘　　要：通过研究化肥减量配施猪粪堆肥对油松(Pinus tabuliformis)生长、养分吸收和土壤肥力的影响,为连作苗圃土壤培肥和培育优质壮苗提供依据。试验在田间条件下,设置不施肥对照(T1)、单纯施用化肥(T2)、化肥+300 g·m^(-2)猪粪堆肥(T3)、化肥+600 g·m^(-2)猪粪堆肥(T4)、化肥+900 g·m^(-2)猪粪堆肥(T5)共5个处理,3次重复。结果表明:化肥添加猪粪堆肥可促进油松生长,其中T4与对照相比株高、地径及根、茎、叶干重分别提高了62.10%、56.82%、88.46%、146.67%、107.14%;T2、T3、T4与对照相比均可提高油松根、茎、叶的氮、磷、钾积累量,T4总氮、总磷、总钾分别较对照提高了136.79%、270.19%、184.31%;各施肥处理均可提高油松根际土氮、磷、钾养分含量,其中T4碱解氮、速效磷和速效钾含量分别较对照提高了38.81%、136.12%、29.77%。化肥减量配施600 g·m^(-2)猪粪堆肥有利于提高油松根际土养分含量,促进植株生长和提高养分积累量。The effects of chemical fertilizer reduction combined with pig manure compost on the growth,nutrient absorption,and soil fertility of Pinus tabuliformis were studied to provide a theoretical basis for soil fertilization and cultivating high-quality and strong seedlings in continuous cropping nurseries.The test under field conditions,and then set up 5 treatments include no fertilizer contro(l T1),simply using chemical fertilizers(T2),fertilizer+300 g·m^(-2) pig manure compost(T3),fertilizer+600 g·m^(-2) pig manure compost(T4),and fertilizer+900 g·m^(-2) pig manure compost(T5),each treatment was repeated 3 times.The results showed that:the addition of pig manure compost to chemical fertilizers could promote the growth of Pinus tabuliformis,and the plant height,ground diameter,root,stem,and leaf dry weight of T4 was 62.10%,56.82%,88.46%,146.67%,and 107.14%higher than control respectively.T2,T3,T4 could increase the accumulation of nitrogen,phosphorus,and potassium in the roots,stems,and leaves of Pinus tabuliformis compared to the control.Compared with the control,the total nitrogen,total phosphorus and total potassium of T4 were increased by136.79%,270.19%,and 184.31%,respectively.All fertilization treatments could increase the nitrogen,phosphorus,and potassium nutrient content in the rhizosphere soil of Pinus tabuliformis,and the contents of alkali-hydrolyzable nitrogen,available phosphorus and available potassium in T4 were 38.81%,136.12%and 29.77%higher than those in the control,respectively.The results of this study showed that the reduction of chemical fertilizer combined with 600 g·m^(-2) pig manure compost was beneficial to increase the nutrient content of rhizosphere soil of Pinus tabuliformis,promote plant growth and increase nutrient accumulation.
