对叶用银杏进行不同施肥方式和不同肥料种类、用量和比例的研究。结果表明: 用30 g· L- 1 绿丰威2 号或尿素+ 磷酸二氢钾进行根外施肥, 单株叶质量增加2228 % ~3778 % 和2033 % ~2444 % 。播种苗基肥用量750 t·h m - 2 的单株叶质量比基肥用量为375 t·h m - 2 的增加9207 % 。采用施尿素277 g·m - 2 、过磷酸钙384g·m - 2 和氯化钾111 g·m - 2 的配方施肥, 单株叶质量增加1202 % 。为叶用银杏栽培提供了适宜的施肥技术。表3 参3
Leaf ginkgo with different fertilization methods and different types of fertilizer, dosage and proportion of research. The results showed that the leaf mass per plant increased by 2228% -3778% and 2033% -24 with 30 g · L -1 Lufengwei 2 or urea + potassium dihydrogen phosphate 44%. The leaf mass per plant at seedling seeding rate of 750 t · h m - 2 was increased by 9207% compared with 375 t · h m - 2 basal rate. The fertilizers with 27.7 g · m - 2 urea, 384 g · m - 2 of superphosphate and 111 g · m - 2 of potassium chloride increased the leaf mass per plant by 1202%. For leaves with ginkgo cultivation provides suitable fertilization technology. Table 3 reference 3
