虽然野生的向日葵(Helianthusspp.)可以建成放牧地、调制干草及作青贮料,但其营养成分的现存资料几乎没有。本研究旨在评估向日葵属26个野生类群,其在不同生长阶段蛋白质及矿物质含量的变化。田间试验设在Pullman粘壤土上,采用随机设计,设三次重复。19个一年出生种,7个多年生种及一个商业用品种“杂种894”分
Although wild sunflowers (Helianthus spp.) Can be grazed, hay and silage, little is known about the nutritional content of the material. The aim of this study was to assess the changes in protein and mineral content of 26 wild populations of sunflower at different growth stages. Field trials were conducted on Pullman clay loam using a random design with three replicates. 19 births a year, 7 perennials and one commercial variety “Hybrid 894”
