摘　　要：在山西省长治市平顺县刘家村,选择生长一致的5年生油松幼林进行浇水、施肥试验,研究不同施肥和浇水处理对油松幼林生长的影响。结果表明,不同施肥处理与对照相比,油松幼林的树高生长量和地径生长量均有一定提高,其中,最好的施肥组合是NPK60。氮肥和钾肥对苗木生长的影响显著,磷肥对苗木生长的影响不显著。混合施肥处理对苗木生长的影响大于单一施肥处理。不同浇水处理对油松幼林树高和地径的生长均有促进作用,对生长量的影响为浇水3次4 L>浇水3次2 L>浇水1次12 L>浇水1次6 L>不浇水。相同浇水方式下,浇水量越大越有利于油松生长;相同水量下,多次浇水效果优于单次浇水。In Liujia Village of Pingshun County at Changzhi City of Shanxi Province,5-year-old Pinus tabulaeformis young forest with consistent growth was selected for watering and fertilization experiments to study the effects of different fertilization and watering treatments on the growth of young Pinus tabulaeformis forests.The results showed that compared with the control,the height growth and diameter growth of young Pinus tabulaeformis forests were significantly improved under different fertilization treatments.Among them,the best fertilization combination was NPK60.The effects of nitrogen and potassium fertilizers on seedling growth were significant,while the effects of phosphorus fertilizer on seedling growth were not significant.The mixed fertilization treatment had a greater impact on the growth of seedlings than the single fertilization treatment.Different watering treatments had a promoting effect on the growth of tree height and ground diameter in young Pinus tabulaeformis forests.The impact on growth was watering 3 times with 4 L>watering 3 times with 2 L>watering 1 time with 12 L>watering 1 time with 6 L>no watering.Under the same watering method,the larger the amount of water poured,the more favorable it was for the growth of Pinus tabulaeformis.Under the same water amount,the effect of multiple pours was better than that of a single pour.
