摘　　要：在千阳县采用单因素对比试验,进行了三种营养土配方(配方A:1m3黄善土+1kg磷酸二氢铵,配方B:1m^3黄善土+50kg有机肥(腐熟干纯牛粪),配方C:1m^3黄善土+25kg草木灰+25kg锯末)对种子繁育容器油松苗效果及苗木生长量及抗性等研究,结果为三种配方平均出苗率98.1%～98.2%、保存率70.5%～94.4%,立枯病发生率2.4%～11.6%,虫害发生率1.9%～14.6%,冻害发生率1.4%～7.8%,株高12.5～14.1cm,地径0.31～0.34cm,苗木出圃率81.6%～92.2%,综合来看配方C最好,配方B次之,配方A最差,油松容器苗生产中可优先选择配方C。In order to cultivate high quality pine container seedlings and solve technical problems in Qianyang County,three kinds of formula nutrient soil on seedling growth test comparison were carried out： formula A 1 m 3 loess＋50 kg Ammonium dihydrogen phosphate; formula B 1 m 3 loess＋50 kg organic fertilizer; formula C 1 m 3 loess＋25kg straw＋25kg saw dust. Mean germination rate with three formulas was 98.1%-98.2%, retention rate 70.5%-94.4%, dampling off incidence 2.4%- 11.6% , and pest incidence 1.9%-14.6%, freezing incidence 1.4%-7.8%,height 12.5 cm-14.1 cm, ground diameter 0.31 cm-0.34 cm, and seedling output 81.6%-92.2%. The formula C performed best, followed by formula B and the least formula A.
