除草剂在野花组合中应用,对降低施工成本起着非常大的作用。野花组合中杂草危害较大,它会争夺养分、水分、光线,成为病虫害的中间寄主,妨碍野花组合播种养护,等等。野花组合建植过程中杂草的控制是工作量最大的环节。经过多年栽培试验,笔者发现,每次翻地整地后都会有很多杂草种子,而且在土壤各土层均有分布,土层越深存活寿命越长,条件合适便发芽生长。因此土壤中的杂草很难除根。
Herbicide application in the wildflower combination, to reduce the cost of construction plays a very big role. The weeds in wildflower combinations are more harmful. They compete for nutrients, moisture and light, become intermediate hosts for pests and diseases, interfere with the planting and maintenance of wildflowers, and so on. The weed control in the process of wildflower combination construction is the most important part of the workload. After years of cultivation experiments, the author found that there will be a lot of weed seeds after each land preparation, and all the soil layers are distributed. The deeper the soil layer is, the longer the living life will be, and the suitable conditions will germinate and grow. So weeds in the soil is very difficult to remove roots.
