肥料是油茶增产的必要因素,为了发挥肥料的最佳效益,做到合理施肥,我们于1984-1987年在麻城市五脑山林场进行了油茶施用氮、磷、钾肥料试验,取得了一定效果,现将试验结果总结如下:一、试验场地及材料选择试验选择在五脑山林场12. 6亩25年生的油茶丰产林内进行,由于油茶品种混杂,采用成片林地试验,品种之间差异太大,为了排除因品种差异而造成的试验误差,因而采取在同一林地随机选择相类似的单株进行试验,每10株树为一个施肥组合,分别设置氮、磷、钾、氮磷钾复合肥(以下简称复合肥)及对照五个施肥组合。
Fertilizer is a necessary factor for the yield of Camellia oleifera, in order to play the best benefits of fertilizers, so as to achieve rational fertilization, we carried out the experiment of applying nitrogen, phosphorus and potassium fertilizers to Camellia oleifera in Wushaoshan Forest Farm in 1984-1987 and achieved some results , The test results are summarized as follows: First, the test site and material selection test selected Wuhushan Forest Farm 12. 6 acres of 25-year-old tea plantation, due to mixed varieties of Camellia, into a piece of woodland testing, the difference between varieties too Large, in order to rule out the test error caused by the differences in varieties, so to take a random selection in the same woodland similar to a single plant test, 10 trees for a fertilization combination, were set nitrogen, phosphorus, potassium, NPK fertilizer (Hereinafter referred to as compound fertilizer) and control five fertilization combinations.
