适龄果树迟迟不结果,除受品种、贴木和土地条件以及苗本质量影响外,主要有以下四种原因。 一是肥水投入少 在幼树期,如果施肥浇水少,放任生长,造成幼树营养不足,难以满足花期物质需要。对这种“饥饿型”幼树,应增加肥水,改善营养状况,才能适期结果。
The results of late-age fruit trees do not result in delay, except for the following four reasons except for the effects of varieties, wood and land conditions and the quality of seedlings. First, less fertilizer into the sapling stage, if less watering fertilization, laissez-faire growth, resulting in young trees lack of nutrition, it is difficult to meet the needs of flowering material. For such “hunger-type” saplings, fertilizer and water should be added to improve the nutritional status in order to achieve the desired result.
