前言在贵州旱地秋收粮食作物中,主要为玉米,其次为豆、薯。豆类又多为间作种植。农业生产虽有有利的自然资源,但当前单产仍不高不稳。如何发挥旱地的生产潜力,是亟待研究探索的课题之一。为此,我们在省的中部地区进行了旱地高产群体结构的探讨,以不同组合形式的玉米大豆间作,以探索结构与产量、地力的关系。目的为探索黔中一般气候类型
Foreword Autumn harvest crops in dry land in Guizhou, mainly corn, followed by beans, potatoes. Beans and more for intercropping. Although agricultural production has favorable natural resources, the current yield is still not very unstable. How to exert the productive potential of dry land is one of the topics to be explored urgently. To this end, we conducted a survey of high-yielding groups in drylands in the central region of the province, intercropping corn and soybean in different combinations to explore the relationship between structure and yield and soil fertility. The purpose is to explore the general climate in central Guizhou
