平凉地区早有黄花栽培,“金针菜”是主要土特产之一。自一九八一年推广优良品种与丰产栽培技术以来,现已基本建成了万亩黄花菜生产基地,其中泾川占74.3％。近几年来,部分乡村群众在四旁为主的林木下间种黄花菜,有其明显的社会经济效益。为了探索林下良好的适合间作物群体,实行合理间作,一地多用、立体种植、充分利用光能和地力,提高单位面积林菜产品的产量和质量,达到生态、经济、社会效益兼顾,促使农业经济结构的有益变化,我们于一九八五年至一九八七年选设有代表性的点,对林木黄花菜间作情况进行了一系列调查,试图为指导种植业生产,推广应用这一新的林菜复合生产种植制度提供依据。
Pingliang area early yellow flowers cultivation, “lily” is one of the main native products. Since the promotion of fine varieties and high-yielding cultivation techniques in 1981, the production base of lily of the million mu has been basically completed, of which Jingchuan accounts for 74.3%. In recent years, some rural people planted lily under the trees which are mainly on four sides, which has obvious social and economic benefits. In order to explore a good suitable inter-crop plantations in the forest, reasonable intercropping, multi-purpose and three-dimensional planting, full utilization of light energy and fertility, and improvement of output and quality of forest and vegetable products per unit area, ecological, economic and social benefits should be balanced We have selected a representative point from 1985 to 1987 to conduct a series of surveys on the intercropping of day-lily trees in order to guide the production and popularization of the planting industry. Provide a basis for a new plantation system of compound production of forest and vegetable.
