杜仲(Eucommia Ulmoides Olla)是我国特产树种,其组织和器官含有硬性橡胶,是良好的绝缘材料,皮、叶是治疗高血压等症的良药,故为国内外所重视,并大量引种栽培.杜仲生长迅速,对土壤要求较高,贫瘠土壤上苗木生长不良.杜仲对肥料反应敏感,过去用农家肥料作底肥,人粪尿作追肥对苗木生长均有良好效果.为了提高苗木质量,促进幼树生长,各地除施农家肥料外,化肥的使用也已与日俱增.为了经济合理地施用化肥,我们采用正交设计设置了氮、磷、钾化肥对杜仲苗期生长的试验,现将结果报导于后.
Eucommia Ulmoides Olla (Eucommia Ulmoides Olla) is a endemic tree species in China. Its tissues and organs contain hard rubber, which is a good insulating material. The skin and leaves are good medicine for the treatment of hypertension. Therefore, Eucommia Ulmoides Olla is widely introduced at home and abroad, Growing rapidly, demanding soil, poor growth of seedlings in poor soil Eucommia is sensitive to the fertilizer in the past with farmyard manure as fertilizer, manure urine for topdressing seedlings have good results in order to improve the quality of seedlings and promote saplings Growth, throughout the addition of fertilizer farmers, the use of fertilizer has also been increasing .In order to economic and rational use of fertilizers, we use orthogonal design nitrogen, phosphorus and potassium fertilizer Eucommia seedling growth test, now the results reported in the post .
