摘 要: | [目的]研究气象因子对冬闲田种植黑麦草产草量的影响。[方法]为探索贵州省冬闲田种植黑麦适宜区域,以产草量为因变量,探讨在不同种植方式下,气象因子对黑麦草产量的影响,[结果]钻石 T总草产量高于特高,条播效果优于撒播,翻耕效果优于免耕;极端高温、低温与产草量呈负相关,而相对较高的日均温、降雨量,较多的日照时数有利于提高产草量。相对湿度、无霜期对产草量作用不明显。[结论]生产中应选择极端气温较少的区域和地点种植黑麦草。

Abstract: | The aim was to research effects of meteorological factors on yield of ryegrass in fal ow field in winter. [Method] With grass yield as a dependent variable, effects of meteorological factors on ryegrass yield were explored by differ-ent planting methods. [Result] The yield of Zuanshi T was higher than that of Tegao; strip sowing performed better compared with dispersedly sowing and plough-ing better than no-til age; extremely high and low temperatures showed negative correlation with grass yield; higher daily average temperature, rainfal and sunshine hour improved grass yield; relative humidity and frost-free period had insignificant effects on yield. [Conclusion] The region with less extreme temperatures should be chosen as the site for growing ryegrass. |
