应用灰色关联分析研究粮菜立体种植模式结构

APPLYING GREY--RELATION ANALYSIS TO STUDY ON GRAIN--VEGETABLE CONSTRUCTION OF SPACE-GROWING MODEL

应用灰色关联分析法，对宁夏引黄灌区粮菜立体种植模式的不同结构，按生态效益，经济效益，社会效益的各项指标进行了综合评价．筛选出了适合宁夏灌区种植的模式结构．其粮食亩产量可接近“吨粮”，亩纯收入达到130O～1400元左右．实现了高产高效．

Applying grey-relation analysis for the different construction of the grain--vegetable space--growing model in channeling Huanghe River into Ning Xia irrigation area, it makes synthetical evaluation to every different index according to ecologic benefit,economic benefit and social benefit.It selects the growing model construction to fit NingXia irrigation area.The grain yield is nearing 1000 kg per mu and net income reaches 1300-1400 yuan per mu.It attains high output and high benefit.
