| 摘 要： | 试验以油茶"华硕"幼苗为试材,采用盆栽试验方法研究金正大、喷施宝、够美等3种水溶性肥料对油茶幼苗生长的影响。结果表明:3种水溶性肥均能显著促进幼苗生长,其中株高和地径增长幅度为21.44%~48.79%和17.88%~32.03%,地上部干重、地下部干重、根冠比和总根长平均增幅为:23.06%、48.75%、21.02%和79.52%;叶绿素含量增长幅度为11.32%~37.74%,其中4%的够美增幅最大,为49.06%;3种水溶性肥料的使用显著提高了苗木的氮、磷、钾含量,其中以够美提高幅度最大。

| Abstract: | The experiment was conducted with Camellia oleifera "Huashuo" as the test material, study the effects of three water soluble fertilizers such as Jinzhengda, Penshibao and Goumei on the growth of Camellia oleifera seedlings by pot experiments. The results showed that: three kinds of water soluble fertilizer could significantly promote seedling growth, plant height and diameter increased the amplification of 21.44%-48.79% and 17.88%-32.03%, the average shoot dry weight, underground dry weight, root shoot ratio and total root length were increased by 23.06%, 48.75%, 21.02% and 79.52%, respectively; The chlorophyll content increased by 11.32%-37.74%, among which 4% Goumei reached the maximum was 49.06%;The use of three kinds of water soluble fertilizer significantly increased the nitrogen, phosphorus and potassium content of seedlings, among them, the largest increase in Goumei. |
