摘要 为了了解缓控肥对油茶轻基质容器苗生长的影响情况,以研发促进容器苗生长的缓控专用肥,以优良无性系长林4#为试验材料,采用单因素完全随机试验设计,设置如下7个缓控肥配方——(1)14:14:14+TE+B.3~6M、(2)15:25:20+TE+B.3~6M、(3)18:18:10+TE+B.4~6M、(4)20:8:10+TE+B.3~6M、(5)20:10:15+TE+B.4~6M、(6)17:11:12+TE+B_3~6M、(7)25:5:6+TE+B.3~6M,每个供试肥料配方处理下又各设置了0.2、0.3、0.4、0.5g/株4个施肥量处理,就不同缓控肥配方及其不同施用量处理对1年生油茶轻基质容器苗生长状况的影响情况进行了试验、观测与分析。结果表明:7个供试肥料配方均能促进苗木地径、苗高的生长及苗木叶片数量的增加,其中配方(3)的效果最优,配方(2)和配方(7)的效果均较优;各配方的最佳施肥量为0.4~0.5g/株,即基质量为2.5~3.0kg/m^3。 In order to find out the effect of slow-released special fertilizer on growth of Camellia oleifera seedlings in light medium containers, and to develop the slow-released special fertilizer for promote growth of container seedlings, taking Chang-Lin No. 4 in superior clones as materials, seven formulas of slow-released fertilizers were set up by adopting a single factor completely randomized experiment. The seven formulas were (1)14 : 14 : 14 + TE + B.3- 6M,(2)15 : 25 : 20 + TE+ B.3-6M,(3)18 : 18 : 10 + TE + B.4-6M,(4)20 : 8 : 10+ TE + B.3-6M, (5)20 : 10 : 15+TE+B.4-6M,(6)17 : 11 : 12+TE+B.3-6M,(7)25 : 5 : 6+TE+B.3-6M. Therewere four fertilizer amount treatments of 0.2, 0.3, 0.4, 0.5 g per plant in each formula. The effects of different formulas and application amount on one year C. oleifera seedlings in light medium containers were observed and analyzed. The results showed that all of the seven fertilizer formulas could promote ground diameter and height growing, and leaf number increasing. Among the fertilizers, the formula (3) had the best effects, the formula (2) and (7) had better effects. The optimal amount of fertilizer was 0.4-0.5 g per plant, or 2.5-3.0 kg/m^3 medium.
