银杏幼树 无土栽培 pH值
銀杏幼樹 無土栽培 pH值
은행유수 무토재배 pH치
Ginkgo sapling; soilless culture; pH
本研究采用了无土栽培法,研究了7个不同水平的pH值下银杏幼树的生长状况。结果表明,不同pH值下银杏的生长状况呈显著差异。pH值极低（pH值小于3.5）情况下,银杏生长叉根部枯死,茎枯死或蔫黄;pH值处于3.5～4.5之间时整个植株生长不良,处于停止或缓慢生长状态,无新根;pH值大于等于5时生长良好。研究结果表明在无土栽培条件下,银杏幼树能适应的pH值范围为大于4.5,最适宜的pH值应大于5。

By soilless culture,we studied the effect of 7 different pHs value on the growth of the ginkgo saplings.The result indicated that significant difference for the growth situation of ginkgo saplings under different pH value.Under the conditions with extremely low of pH value（pH value is smaller than 3.5）,the ginkgo saplings dispatch a root segment to die,and the stems die or turn yellow.When PH value is between 3.5 and 4.5,the entire plant grows bad,in situation of slow or no growing,and with no new root;when the pH value is larger than 5,the ginkgo saplings grow well.Result of the present study show the pH value should be larger than 4.5 for the ginkgo saplings to grow,and the most proper pH value is greater than 5.
