油茶Comellia oleifera Abel到2月份时一般落花率即达40％—52％,而经过微量元素处理的,落花率明显降低。果实成熟时用微量元素硼处理的试验区,存果率要比对照组高20％以上,1983年高达90％。经0.1％硼处理的试验区,其含油率也比对照高8.25％。油料植物的种子产量及含油率,随着不同的植物和类型以及环境条件的变化相差很大。其原因除植物本身固有的特性外,在复杂的环境条件下,矿质营养中的微量元素也是很重要的因素。它们是某些酶类和辅酶的组成部分或活化物质,对开花、结果以及物质转化等都有很大影响,有时甚至起着决定性的作用。微量元素硼、钼对油菜和花生等作物处理,可明显看到增产效果,但对木本油料作物的增产效果报导甚少。本试验试图通过不同的微量元素对油茶植株进行处理,以了解某些微量元素对油茶的落花落果及含油率的影响,为油茶的施肥管理提供参考。
Camellia Comellia oleifera Abel generally fell 40% -52% in February, while the amount of flowerings dropped significantly after trace element treatment. Fruit ripening with trace elements boron treatment area, the stock rate was 20% higher than the control group, up to 90% in 1983. The test area treated with 0.1% boron also had a higher oil content of 8.25% than the control. The seed yield and oil content of oilseed plants varies greatly with different plants and types and environmental conditions. The reason for this is that in addition to the inherent properties of the plant itself, trace elements in mineral nutrition are also important factors under complex environmental conditions. They are an integral part or activator of certain enzymes and coenzymes and have a large influence, sometimes even decisively, on flowering, fruiting and transformation of matter. Trace elements boron, molybdenum on rapeseed and peanut crops, can clearly see the yield increase effect, but little effect on the yield of woody oil crops reported. This experiment tried to deal with the Camellia oleifera plants by different trace elements to understand the effect of some trace elements on the falling and fruiting of Camellia oleifera and provide reference for the fertilization and management of Camellia oleifera.
