摘要
本文从间混作系统的整体出发,运用生态学原理论述了间混作研究中密度、施肥量、两种作物之间的比例关系、产量的表示方法和总产的计算问题,并运用粗密度、生态密度和标准化产量概念阐明了间混作实占面积与整体面积产量以及总产的计算问题,将行比与作物比有机地结合在一起,从而能够更加完整地反映出间混作的空间排列和群体大小。
Density, quantity of fertilizer dressing, ratio between intercropping crops, ways for calculation yield and total output in intercropping research were discussed in relation to the whole intercropping system and ecology theory,then conception of crude density,ecological density and standardization yield and total output were used to solve the problems in calculation of real area,whole area,yield and total output of intercropping crops in this paper, By combination of proportion of row with proportion of crops the spacing and population of intercropping crops can be described.
