Analysis Of Influencing Factors Of Spuriopiminella Brachycarpa's Growth And Nutritional Quality Under Canopy In Eastern-Liaoning

With the draining of forest wood the implementation of the public welfare forest protection and forest right reform policies, forest region economy must shift towards undergrowth management, it has become one of the main directions of the development of Spuriopiminella brachycarpa and other mainly wild vegetables. In order to increase the income of farmers and motivate them to protect the public welfare forest, this study is based on the comprehensive investigation of Spuriopiminella brachycarpa's growth environment in Eastern-Liaoning Qingyuan County is represented to set up test sample. Investigations are carried on to analyze different site conditions and environmental factors influenced Spuriopiminella brachycarpa's yield and using multivariate analysis of variance to investigate Spuriopiminella brachycarpa's growth status in this area. It aims to find the most suitable planting mode for its growth, that is, the cultivation mode to get the maximum economic benefits.The results of the study for:(1) Forest types, aspec, slope position and slope have very significant influences on the growth of Spuriopiminella brachycarpa; The aspec and slope and of the Spuriopiminella brachycarpa exhibition leaf number has a significant impact(p<0.01). Spuriopiminella brachycarpa's plant height which under canopy is about 3 times higher than those all-optical hilly field; Comprehensive the results:in the conditions of larch plantation, uphill and semi sunny slope, slope of 15?20° is the most suitable for Spuriopiminella brachycarpa growth, and the highest for economic benefits. Spuriopiminella brachycarpa can be constructed by fitting the model output binary linear regression equation based on plant height and leaf number.(2) Forest types, aspec, slope position and slope have very significant influences of the carotenoid content in Spuriopiminella brachycarpa. Under-forest the carotenoid content in Spuriopiminella brachycarpa is apparently higher than that carotenoid content in Spuriopiminella brachycarpa of bare land to grow.In the conditions of larch plantation, uphill and semi sunny slope, slope of 15?20° has the highest carotenoid content in Spuriopiminella brachycarpa.(3) Forest types and slope position have very significant influences of the Crude protein content in Spuriopiminella brachycarpa. Under-forest crude protein content in the Spuriopiminella brachycarpa is slightly higher than than those all-optical farmland to grow for the crude protein content in the Spuriopiminella brachycarpa. In artificial under-forest of crude protein content in the Spuriopiminella brachycarpa is higher.(4) Mineral element content in Spuriopiminella brachycarpa and Forest types and slope relationship between the maximum. The under-forest and all-optical farmland Mn element under the most obvious difference.Three elements Ca, Mg, Fe is affected by comprehensive site conditions is larger. Two kinds of trace elements Cu and Zn relatively less affected.(5) Comprehensive the above results:the study screened larch plantation, the semi-sunny, slope of 15-20 uphill for the best Spuriopiminella brachycarpa cultivation point.
