山东花生低产区主要分布在鲁中南山地丘陵区和鲁东低山丘陵区,约占总种植面积的70％。这部分产区限制产量的主要因素是“一旱二薄”,生产条件低下,缺乏与生态条件和生产条件相适应的优良品种和配套技术,致使产量低而不稳,常年亩产徘徊在125公斤左右。为提高这些产区的花生产量,尽快达到中产水平,我们从1987年开 Shandong peanut low-yield areas are mainly distributed in Luzhongnan hilly and Ludong low hilly areas, accounting for about 70% of the total planted area. The main factors restricting the output of this part of the producing areas are “one dry and two low”, low production conditions, lack of fine varieties and supporting technologies that are compatible with ecological conditions and production conditions, resulting in low and unstable output. Annual perennial mu production hovers at 125 Kg or so. In order to increase the production of peanuts in these areas and reach the middle class as soon as possible, we opened in 1987
