谷子是我国北方主要旱作作物,适宜在山区、半山区、干旱及半干旱地区种植,具有抗旱、耐瘠和适应性强的特点。“张杂谷”系列品种是由张家口市农科院选育而成的优质高产谷子杂交种,2008年引入蓟县,深受广大农民的欢迎。当前在“张杂谷”的生产上,发生的病虫害主要是穗瘟病和栗灰螟(谷子钻心虫)。为保障“张杂谷”的高产稳产,在整个生长发育期内要做好病虫害的防治工作。
Millet is the main dry crop in the northern part of our country. It is suitable for planting in mountainous, semi-mountainous, arid and semi-arid areas. It has the characteristics of drought resistance, barren resistance and adaptability. “Zhang Zonggu ” series of varieties is the high quality and high yielding millet hybrids, which was bred by Zhangjiakou Academy of Agricultural Sciences. In 2008, it was introduced into Jixian and was well received by farmers. Currently, the main plant diseases and insect pests that occur in the production of “Zhang Zonggu” are the head blast and the chestnut gray borer (millet borer). In order to protect the high and stable yield of “Zhang Zigu”, it is necessary to prevent and control pests in the whole growth period.
