比较了5种不同基质对油橄榄容器苗移栽成活率、新根数、苗高、基径、根长、新梢数、地上部和地下部干、鲜质量和质量指数等10个性状的影响.结果表明:以园土和椰糠体积比3∶1混合而成的复合基质,油橄榄容器苗移栽成活率较高,幼苗梢、根、叶生长俱佳,质量指数优于其他处理,是1年生油橄榄容器育苗的理想基质;而纯椰糠基质酸性强,不利幼苗生长,不宜作为油橄榄容器育苗基质单独使用.在园土和椰糠体积比3∶1的复合基质中,1年生大棚油橄榄容器苗苗高可达76.2 cm,基径6.25 mm、新梢5.27个,基本符合壮苗标准.并且,苗高的生长存在"两快两慢"过程,春、秋两季快,夏、冬两季慢;基径增粗在整个生长期相对平缓,表现出前、后期较快,中期相对较慢的特点,在入秋后,当苗高达到一定高度时,新梢开始加快抽发速度.此外,该文章还探讨了油橄榄容器苗相关质量评价指标的有效性.%The effects of five substitutes on ten agronomic traits of container-seedlings of olive including survival rate, number of new produced root, plant height, stem base diameter, root length, number of new shoots, fresh and dry weight of above-ground and underground parts of plant, dickson quality index(DQI) of olive were evaluated under plastic greenhouse condition.The results showed that the combination of soil and coconut coir dust with 3∶1 ratio was the ideal substrate for annual container-seedlings of olive, favorable for the growth of shoots, roots as well as leaves of the young seedlings.Seedlings grown in the substrate had higher survival rate and better DQI, while the pure coco chip was very unfavorable for olive seedling growth due to its strong acidity, suggesting that it was not suitable for use as a substrate.Under the substrate (the combination of soil and coconut coir dust with 3∶1 ratio), the annual olive seedling could grow up to 76.2 cm in height, 6.25 mm in the stem base diameter, and 5.27 new shoots in plastic green house, which was accorded with the seedling standard of the stage.Moreover, the seedling height grew fast in spring and fall, and slow in summer and winter.The stem base diameter thickening showed relatively fast in early and late periods, relatively slow in middle period.Shoot began to accelerate the pumping speed in the autumn when the seedling height reached a certain level.In addition, the effectiveness of parameters related to quality evaluation of olive container-seedlings was also discussed in the paper.
