在长江下游地区,小麦产量不断上升,显示了南方小麦的巨大增产潜力。这一地区迫切需要特早熟的小麦品种,以实现“一早带二早”,促进全年增产。在抗御灾害方面,小麦赤霉病为害大,频率高,在农业防治和药剂保护方面虽已有相当进展,但仍十分需要选育抗病品种,作为控制为害的根本措施。 In the lower reaches of the Yangtze River, wheat production is on the rise, showing the huge yield potential of southern wheat. Urgent precincts of wheat are urgently needed in this region in order to bring “early morning and early morning with the second morning” and boost the annual production. In combating calamities, scab has a high incidence and high frequency. Although considerable progress has been made in agricultural prevention and protection of pesticides, there is still a great need to breed resistant varieties as a fundamental measure to control damage.
