试验证明,玉米田整秸秆覆盖后玉米螟和玉米黑粉病危害减轻,地下害虫和玉米丝黑穗病加重。如果在较大面积上连续数年实施这一技术,这四种病虫都存在加重趋势。玉米黑粉病仍然是某些年份玉米上的一种不可忽视的病害。玉米丝黑穗、玉米黑粉病及玉米螟的防治策略是尽可能地减少覆盖秸秆中病穗的残存和越冬虫基数;地下害虫的防治应推行种子包衣技术和在危害期撒播毒饵的方法。
Experiments show that corn field cover the whole corn stalk and corn powdery mildew hazard reduced, underground pests and maize smut aggravate. If this technology is implemented for many years in a large area, all four pests and diseases have an increasing tendency. Corn powdery mildew is still an undeniable disease on corn in some years. Corn black smut, corn smut and corn borer control strategy is to reduce as much as possible to cover the disease remaining in the straw and the number of overwintering insects; prevention and control of underground pests should be the introduction of seed coating technology and poisoning during the poisoning bait method .
