摘要
海南岛荔枝花芽分化的早晚受气温高低和干旱情况的综合影响,为了能够对其实施预报,本文利用费歇尔准则,根据低温条件和干旱指数两因子建立了"妃子笑"荔枝花芽分化期的判别模型,利用此式对待判样品进行试报,准确率为100%。
The temperature changes and drought influence on the flower bud differentiation of Litchi （Litch chinensis Sonn. ） in Hainan Province. A discriminatory function formula mainly based on low temperature condition and arid index for Litchi variety Feizixiao was established to make judgement of the period of flower bud differentiation. The model passed F - test. The validation showed an accuracy ratio with 100%.
