河北省邢台农业科学研究所玉米研究室选育的“邢抗2号”抗虫玉米杂交种,于1999年2月正式通过河北省农作物品种审定。这在我国尚属首例。邢抗2号玉米杂交种集高产稳产、抗虫抗病、抗倒耐早、绿叶活秆成熟为一身,是发展“两高一优”农业、节水农业和畜牧业的适宜品种。大面积种植抗虫玉米,可使玉米从害虫的寄主,变成害虫生长发育的障碍因素,多代种植可造成害虫数量的连年下降。并且不污染环境,不危及人畜健康,不但可增加玉米的收益,而且还可减轻害虫对棉花和蔬菜的危害,既能增收又可节省农药开支和用工,是提高社会效益、经济效益和生态效益最经济 Hebei Xingtai Institute of Agricultural Sciences maize breeding laboratory breeding “Xingkang 2 ” insect-resistant corn hybrids, in February 1999 formally approved by the crop varieties in Hebei Province. This is the first case in our country. Xingkang 2 corn hybrids set high and stable yield, insect resistance and disease resistance, early resistance to resistance, green leaf stalk mature as one, is the development of “two high and one excellent” agriculture, water-saving agriculture and animal husbandry suitable varieties. Large-scale planting insect-resistant corn, corn from the pest host, into the growth and development of pests obstacles, multi-generation planting can cause the number of pests decline year after year. And does not pollute the environment and endanger the health of human beings and animals. It not only increases the yield of corn, but also reduces the harm of pests to cotton and vegetables.
