为了使果用银杏达到优质、高产、高效,必须掌握合理的施肥技术。 1.配方比例 研究表明,果用银杏施用氮、磷、钾的比例以5.5:1:3为最好,比习惯施肥平均增产20％以上。 2.施肥量 一般每生产100公斤银杏,约需尿素11公斤,钙镁磷肥2公斤,氯化钾6公斤。上述施肥量不是一成不变的,应结合树势,经营管理技术水平等因素综合考虑,尽量施用有机肥。 3.施肥时间 一般3月份施叶前肥,6月份施促花催果肥,9月份施果后肥。
In order to make the fruit ginkgo to achieve high quality, high yield, high efficiency, we must master the reasonable fertilization technology. 1 formula ratio studies show that the application of ginkgo nitrogen, phosphorus and potassium ratio of 5.5: 1: 3 for the best, more than the average yield of 20% or more than conventional fertilization. 2. The amount of fertilizer per 100 kilograms of general production of ginkgo, about 11 kg of urea, calcium magnesium phosphate 2 kg, potassium chloride 6 kg. The amount of fertilizer is not static, should be combined with the tree potential, management and technical factors and other factors considered, as far as possible the application of organic fertilizer. 3. Fertilization time is generally applied in March foliar fertilizer, fertilizer in June prompted the urge to promote fruity, fruiting after September fertilizer.
