Although crystal pear is resistant to drought, cold, barren and has strong adaptability, it must be cultivated in the best cultivation place for efficient cultivation. The soil layer for crystal pear cultivation should be deep, the soil quality should be fertile and rich in organic matter. Sand loam or loam soil should be the best cultivation soil, and it is better to have certain irrigation and drainage capacity. Fertilization management Spring is the period for the growth and construction of pear organs. The growth of roots, branches, leaves and flowers accelerates with the rise of temperature. Adequate nitrogen supply is required for pollination, fertilization and fruit setting. May to June is the period of young fruit expansion, most leaves set, new shoot growth gradually stops, photosynthesis is vigorous, carbohydrates begin to accumulate. During this period, nitrogen demand decreased significantly, but stable nitrogen supply should be maintained. Overeasiness led to the growth of shoots, prolonged growth period and reduced flower bud differentiation. Too little is easy to premature leaf aging, tree potential decline, fruit growth slow. When nitrogen was stopped after mid-August, there was no significant effect on fruit size, otherwise, fruit flavor decreased. The maximum phosphorus absorption period was from May to June and decreased after July. Nutrient absorption is related to the growth of new organs, and the peak of new shoot growth, young fruit development and root growth is the peak of phosphorus absorption. The middle of July is the second peak of potassium absorption, and the amount of potassium absorption is much higher than that of nitrogen. At this time, pear fruit is in the rapid expansion stage, and the demand for potassium is still high in the later stage, and the insufficient supply of potassium in the later stage will lead to the fruit can not fully develop and the flavor will be poor [1].
