本省万余亩结果油茶树均系普通油茶(Camellia oleifera Abel),历年花量很多,座果甚少,花而不实现象极为严重。据调查,每平方米冠幅有花50—200朵,多者可达400朵以上,但能形成幼果的花仅有30—40%,有60—70%的花朵不能形成幼果即行脱落。而一旦幼果形成,则落果不多,成果率是较高的。普通油茶由于大量落花,造成产量少、产值低,成为本省油茶生产中一项急待解决的问题。为促进油茶座果,我们于1980年秋季应用微量元素和生长素在油茶花期进行了喷冠试验,现将试验结果报道如下:
Camellia oleifera Abel, the result of more than 10,000 mu in Camellia oleracea trees, has a lot of flowers over the years, with few fruit and flowers, but without serious consequences. According to the survey, there are 50-200 flowers per square meter of crown width, with more than 400 flowers, but only 30-40% of young flowers can be formed, and 60-70% of flowers can not form young fruits and fall off . Once the young fruit is formed, the result is low. Ordinary Camellia due to a large number of falling flowers, resulting in less output, low output, become the province’s camellia production an urgent issue to be solved. To promote Camellia fruit, we applied trace elements and auxin in the fall of 1980, during the flowering period of Camellia spray test, the test results are reported as follows:
