油茶是产量较高,寿命很长的木本油料,但是往往由于营养不良,落花落果比较严重,秕粒较多,没有充分发挥其丰产性能。因为油茶从发芽抽梢,换叶孕蕾, 壮果长油,果熟花开的周期生长发育中,每年都要从土壤中吸取大量的营养物质,随着时间的增加,必然会使土壤中营养物质逐渐贫乏。而且栽种油茶的红壤土,氮和磷都比较缺乏,特别是有效磷更缺,所以要加强油茶的培育管理,就要及时增施肥料,才能缩小大小年,获得高额丰产。永兴县枣子大队、丹平大队在蜂窝坪、葫芦形进行施肥对比试验,施肥后发的新梢
Camellia oil is a high-yield, long-lived woody oil, but often due to malnutrition, falling more serious, more grains, did not give full play to its high yield performance. Because the tea buds from germination buds, leaf buds for pregnant, strong fruit long oil, ripening cycle of growth and development, each year to draw a lot of nutrients from the soil, with the increase of time, will inevitably make the soil Nutrients gradually poor. In addition, the red loam planted with Camellia oleifera soil is relatively scarce, especially the available phosphorus is scarce. Therefore, in order to strengthen the cultivation and management of Camellia oleifera, fertilizers should be added in time so as to reduce the size of the year and obtain the high yield.
