糜(Panicum miliaceum)、谷(Setariaitalica)是黄土高原半干旱地区两种重要传统作物,常交错分布,在多年的生产实践中表现了不同的适应干旱的生理特性。但在不同土壤干旱条件下,如何合理布局,缺乏依据,有时在一个地区不加区别的同时扩大或缩小种植面积,影响了产量。文献中糜、谷抗旱生态生理方面的报导不多,且尚未见到它们的比较研究
Panicum miliaceum and Setariaitalica are two important traditional crops in the semi-arid area of the Loess Plateau. They are often staggered and show different physiological characteristics of drought-adapted to drought in many years of production practice. However, under different soil drought conditions, how to make a rational distribution and lack of basis are sometimes expanded or contracted in the same area without any distinction at the same time, affecting the output. There are few reports on ecological and physiological aspects of drought resistance and drought resistance in the literature, and comparative studies of them have not yet been found
