The Technological Study For Improving The Fruit Rate Of Xanthoceras Sorbifolia, A Unique Chinese Energy Species

Xanthoceras sorbifolia is the only specie in the Xanthoceras family members,It’s one of the relict plants of the Tertiary period and a high grade energy plant peculiar to China,It only distributes in north china,where is severe and mostly dry,The Xanthoceras sorbifolia is of a very high value,but its wild resources is decreasing while the production of the artificial cultivation is very low,The reasons of its low fruit setting and endangered wild resources may attribute to the following,such as the oversized input in its flowering phase,the low fruit setting,the male and female abortion,the inbreeding decline, the reproductive resolution caused by the broken habitation, the retrogression of the small groups and human detriment.The paper aims to keep the production of the Xanthoceras sorbifolia garden at a high level and puts forward a scheme of a Xanthoceras sorbifolia garden and its management measure through a series experiments on its pollination and mating,reproduction distribution and tree surgery,as well as the reproduction control strategy,Three conclusions are reached:First,pollination trees are rec ommended in a garden for the fruit setting may increase about10%when the flowers are cross pollinated,and most of the infertile flowers should be removed to supply those fertile flowers with more nutrition,It also helps with some GA and ABA in its blooming period.Second,tree surgery is recommended every winter,Pay attention to its law of branching,keep its layer in a nature station,remove those deadwood and carpophores in time,Restraint in vegetative growth such as twist,girdling and branch pulling in summer is also helpful in fruit setting.Third,it’s also essential to fruit setting with good species,pollination trees,good grafting, hormone spraying and good measurement in water and fertilizer.
