有了好的栽培技术和管理条件,还必须采用适宜的种植密度,才能有效地利用光能和地力,增加产量。1.密度与产量的关系:在一定限度内,适当增加密度,有明显的增产效果。例如,种植晋杂1号高粱,每亩4,444株时产量为755斤,5,240株时产量为786斤,7,692株时产量为846斤,8,511株时产量则为851斤。当密 With good cultivation techniques and management conditions, appropriate planting densities must also be used in order to effectively utilize light energy and soil fertility and increase production. 1. The relationship between density and yield: Within a certain limit, an appropriate increase in density, a significant yield increase. For example, when planting Jinza 1 sorghum, the yield of 4,444 plants per mu was 755 kg, that of 5,240 plants was 786 kg, that of 7,692 plants was 846 kg, and that of 8,511 plants was 851 kg. When dense
