覆膜对酒竹笋营养元素与成分的影响

2004年引进了原产非洲东部中高山地区的竹亚科(Bambusoideae)锐药竹属(Oxytenanthera Mun-ro)竹种--酒竹(O.braunii Pilger ap.Engler),经过近4年的引种栽培,实地调查发现,与邻近勃氏甜龙竹(Dendrocalamus brandisii Kurz)、马来甜龙竹(D.asper (Schult.f.)Backer ex Heyne)、麻竹(D.latiflorus Munro)竹林相比较,笋横锥大象(Cyrtotrachelus buqueti Guer)、笋直锥大象(C.longimanus Fabricius)和巨红蝽(Macroceroes grandis Gray)特别喜食酒竹笋.

Effect of Plastic F ilm Mulch ing on Trace Element and NutritionofW ine Bamboo Shoot, Oxy tenanthera braunii

The a im o f this paper is to prov ide the data that the transplant advantage in sou thw est arid ity area of Chinaso that shoot? s trace e lement and nutritional components ofw ine bamboo, Oxy tenanthera braunii, through thew in terespecially under p lastic film mulch ing condit ion w eremeasured. The resu lts show ed that p last ic film mulch ing cou ldprecede in t ime o f shoot germ ina tion and enhance the shoot qua lity such as improv ing absorbab ility of trace elemen,tincreasing content o f prote in, sugar, coarse f iber and ma jor ity o f am ino acid. And a lso, it cou ld acce lerate thedevelopment of shoo t responding to the difference o f base d iame ter. W ine bamboo? s trace elementw as rich, and thecontent o f crude fat and sugarw ere h igher compared w ith the shoot ofPhy llostachy s edulis, P. edulis cv. p achy loenand Dendrocalamus brand isii w ith the closer relat ionship that the ex cret ing sap contained about 5% a lcoho l throughnew cutt ing stem. W ine bamboo germ inated shoo ts in w ho le year at Mo jiang Base if mother plan t could absorbenough nutrition resulting in great consumption o f nutriment and physiolog ical turbulence like decreasing am ino ac idcontent under an inaptitude condition.
