该文阐述了不同播种期小麦基本苗对粒叶比影响的试验情况,结果表明扬麦14号在10月23日到11月16日之间播种时,粒叶比随着基本苗的增加而减少。在实际生产中,并不是一定要高的粒叶比,而是要针对具体品种高产优质科学的粒叶比,以本试验为例,约0.42~0.56时是最理想的。
The paper described the effect of basic seedlings on grain-leaf ratio at different sowing dates. The results showed that grain-leaf ratio increased with the increase of basic seedling number when Yangmai 14 was sowed from Oct. 23 to Nov. 16 cut back. In actual production, not necessarily high grain-leaf ratio, but to specific varieties of high yield and quality of scientific grain-leaf ratio to the test, for example, about 0.42 ~ 0.56 is the best.
