一、科学施用肥料。首先要注意秋施基肥,就是从果实采收后到落叶前这段时间内,越早越好。秋施基肥正是根系二次生长的高峰期,该时期施肥主要优点一是伤根易愈合,可发生大量新根,有利于树体的营养积累;二是土壤温度相对较高,有机质易于腐熟分解;三是来年春季萌芽、开花时能直接提供足够营养,满足树体需要,提高座果率。试验证明秋施基肥比春施基肥座果率可提高10%左右。追肥时间一般应在发芽前、开花前和浆果生长期各施一次。在施肥种类上,提倡使用复合肥,注意增施钾肥,氮、磷、钾比例应为0.5:1:1.5,施肥量按树
First, the scientific application of fertilizer. First of all, we must pay attention to autumn base fertilizer, that is, after the harvest from the fruit to the leaves before this period of time, the sooner the better. Autumn base fertilizer is the root of secondary growth of the peak period, the main advantage of fertilization during this period is wound root easy to heal, a large number of new roots can occur, is conducive to the accumulation of tree nutrition; the second is the soil temperature is relatively high, easily decomposed organic matter Decomposition; third spring budding the following year, flowering can provide adequate nutrition, to meet the needs of the tree, improve the rate of fruit set. Tests show that autumn base fertilizer than spring Shi-base fertilizer fruit rate can be increased by about 10%. The top dressing time should generally be applied before germination, before flowering and during the growth of the berries. In the type of fertilizer, to promote the use of compound fertilizer, pay attention to the application of potash, nitrogen, phosphorus and potassium ratio should be 0.5: 1: 1.5, the amount of fertilizer by tree
