对河南宁陵酥梨进行了叶片、新梢、果实生长发育及花芽分化的观察，结果表明，短枝叶片生长高峰期为４月３日－１４日；新梢生长高峰期为４月１４日－５月１４日；果实体积增长高峰期为７月２５日－８月１２日和８月２４日－３０日；花芽形态分化初期为６月下旬，大量分化期为７月２９日－８月２８日。在叶片生长高峰前约两周进行追肥灌水，可促使叶片加厚和叶面积增大，促进新梢及叶片生长。由于果实迅速增大期又是花芽大量分化期，因此，在此之前约１５ｄ进行追肥灌水，可为果实生长及花芽分化扩大营养物质的库源，解决同期需要养分的矛盾。
The observation of the growth, development and flower bud differentiation of Ningliu pear in Ningling, Henan Province showed that the peak growth of short branches was April 3-14 and that of the new shoots was April 14 - May 14; the peak of fruit volume growth was July 25-August 12 and August 24 -30; the early stage of flower bud differentiation was late June, and the large-scale differentiation period was July 29-August 28th. About two weeks before the peak of leaf growth, topdressing irrigation can promote leaf thickening and leaf area increase, and promote the growth of shoots and leaves. Due to the rapid increase of fruit is a large number of flower bud differentiation period, so before about 15d for top dressing and irrigation, for fruit growth and flower buds to expand the source of nutrients, to solve the contradiction of nutrient needs over the same period.
