[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。
[Objective] The research aimed to study the effect of meteorological factors on the production of ryegrass in winter fallow fields. [Method] In order to explore suitable planting area of rye in winter fallow fields in Guizhou Province, the yield of grass was used as the dependent variable to investigate the effect of meteorological factors on the production of ryegrass under different planting patterns. [Result] High, the sowing effect is better than sowing, plowing effect is better than no-tillage; extreme high temperature, low temperature and the yield was negatively correlated, while the relatively high daily average temperature, rainfall, more sunshine hours conducive to raising production Grass volume. Relative humidity, frost-free period on the role of grass is not obvious. [Conclusion] Lolium should be planted in areas and locations with less extreme temperatures in production.
