谷子又名粟,是我国北方的主要粮食作物之一。谷子具有抗旱、耐瘠、适应性强的特点。对土壤要求不严格,能在各种土壤上种植。近年来,随着高产、抗病、抗倒伏的优良品种的不断育成,栽培水平的不断提高,谷子的单位面积产量也在迅速提高。为保障谷子的高产稳产,在整个生长发育期内要做好病虫害的防治工作。1.选用抗(耐)病品种或无病良种良种是增产的内因,选用良种是谷子生产上投资少、增产显著的重要措施。目前培育出的抗谷
Millet, also known as millet, is one of the main food crops in northern China. Millet has drought, barren, adaptable characteristics. Not strict on the soil, can be planted in a variety of soils. In recent years, with the high-yielding, disease-resistant, lodging of fine breeds continue to bred, growing levels of cultivation, grain yield per unit area is also rapidly increasing. In order to protect the high and stable yield of millet, we must do a good job in the prevention and control of pests and diseases throughout the growth period. 1. The selection of resistant (resistant) varieties or disease-free elite varieties is the internal cause of increased yield, selection of elite is millet production less investment, an important measure to increase production significantly. Currently cultivated anti-valley
