【摘要】 对妃子笑荔枝开花期及坐果情况进行观察,发现第一批雌花的开放时间与第二、第三批雌花的开放时间相差15～25天,但成熟期仅相差7～10天,坐果情况差异较大。通过对妃子笑荔枝不同花期果实即早花果和迟花果的大小以及叶、果营养差异进行分析,结果表明:早花果个体大,早熟,叶、果营养水平高,品质优;迟花果个体小,迟熟,叶、果营养有较大差异,并指出早花果与迟花果坐果差异较大的原因。更多还原

【Abstract】 According to our observation on florescence and sit-fruit status, there are 15～25 days delaying among the 1st female flower abloom batch, 2nd and 3rd. But the ripe fruit period is only 7～10 days difference. Sit-fruit status is quite different among batches. Over analyses on the different periods of fruit, forepart fruit & late fruit and their sizes and the nutrition difference of leaves and fruit, the result shows: forepart fruit is larger in size, ripe earlier with higher quality and better nutrition on leaves & fruit than which after. Late florescence, fruit is smaller in size and late in ripe, the nutrition of leaves & fruit with greater difference. Meanwhile, those analyses point out the reason why so many sit-fruit differences among forepart and after.更多还原
