Study Of Cultivation Of Introduced Species On The United States Almond Lee In Tian Shui Area

Sduty on five species 0f The United States Almond Lee from The United States.It`s Wei Di,Feng Wei Huang Hou,Feng Wei Mei Gui,Wei Hou,Kong Long Dan which it's from zheng zhou of he nan Province at March 12,2004.To measure the growth quantity of species and soil water content. To analyse data by Excel and sas.The result indicate:⑴Growth process 0f The United States Almond Lee of five species is similar, and belong to full-year growth pattern species. Preservation rate of species of afforestation are higher,It have normal growth and development,and adapted to natural conditions in the examination's area.⑵Fruits of weidi and fruits of weihou matured early, feng wei huang hou and feng wei mei gui matured middle, kong long dan matured later, mature period of five species differed between 10～15d,to composed mature Series of early,middle,later.⑶Average soil water of woodland of Cultivation model 1,2,3 are higher, average soil water of woodland of Cultivation model 4,5 are lower; Soil water between 5 ~ 10 month have overall increasing trend, but cultivation model 2,3,5 have larger drop in July.⑷The comprehensive analysis of many factors indicate, first pprincipal component is Growth and development and second principal component is soil water and factor of branchs'development , five species separated three category that is wei di and feng wei huang hou,feng wei mei gui,wei hou and kong long dan.⑸In the examination's area, Cultivation model 1 is that growth si bigger,fruit is higher,water consumped lower, it higher in July, The Cultivation models 1 adopt to the area which have some irrigation condition; The Cultivation models 2,3 are that growth si middle,water consumped lower, which can be used in area of better site content; Cultivation model 5 is that growth si lower,fruit is middle and mature is later, water consumped bigger, which can be control used in area of better soil water content.
