烟草的保护性耕作体系可保存土壤湿度并切实减少因风雨造成的能量消耗和土壤侵蚀。保护性耕作还可以允许烟农在阴雨天气里适时施用田间杀虫剂。由于机械化耕作在保护性耕作方式中不作为除草剂的补充,从而使得在整个生长季的杂草控制变得困难。躲过了早期田间除草剂的阔叶杂草将
Tobacco conservation tillage systems conserve soil moisture and effectively reduce energy consumption and soil erosion due to wind and rain. Conservation tillage can also allow farmers to timely apply field pesticides in rainy days. Mechanized farming is not supplemented with herbicides in conservation tillage, making it difficult to control weeds throughout the growing season. The broad-leaved weeds escaped the early field herbicides will be
