杂交谷子不同地膜覆盖方式研究

Comparison of Different Film Covering Methods for Hybrid Millet

以2种杂交谷子不同地膜覆盖方式为研究对象,研究地膜覆盖方式对杂交谷子产量及用水量的影响。结果表明:地膜全覆盖处理与常规旱地直播相比虽然前期经济层面投入加大,但后期有效防控了草害,免去了除草,而且产量增加明显,整个生育期减少1~2次浇水,极大地减少了资源投入和人力投入。

The effects of mulching methods on the yield and water use of hybrid millet were studied by using two kinds of hybrid cultivars with different mulching methods. The results showed that： although the investment in the mulching of the mulching film was higher than that of the conventional dry land, the grassland damage was effectively prevented and prevented at the later stage, and weeding was eliminated, and the yield was increased significantly. The whole growth period was reduced by 1-2 times of watering, greatly reducing resource investment and manpower investment.
