摘要
通过对盆栽油茶幼苗喷施几种叶面肥试验,分析了其对1年生油茶幼苗苗高、地径、比叶重、叶绿素含量及叶绿素a/b的影响。结果表明:不同叶面肥对油茶幼苗生长的影响各不相同。1.5%尿素能显著提高幼苗的苗高;0.1%磷酸二氢钾+0.2%硼肥能显著促进地径增长;0.15%红A硼能显著提高油茶叶片的叶绿素含量与比叶重;不同配方叶面肥均能显著提高油茶叶片比叶重。叶面肥的合理选择及施用能促进油茶幼苗的生长,在油茶优质苗木生产中具有广阔的市场前景。
Pots experiment was conducted to study the effects of foliar fertilizer on the height, ground diameter, specific leaf weight, chlorophyll content and chlorophyll a/chlorophyll b of one year old Camellia oleifera seedlings. The results showed that the foliar fertilizer had obvious effects on the growth of C. oleifera seedlings. 1.5% urea could significantly increase the seedling height, while 0.1% potassium dihydrogen phosphate and 0.2% boron fertilizer could significantly promote the growth of ground diameter. 0.15% Red A boron fertilizer could significantly increase the chlorophyll content and the specific leaf weight, and all formulas of foliar fertilizer could significantly increase the specific leaf weight. The reasonable selection and application of foliar fertilizer was of significance in promoting the growth of C. oleifera seedlings.
