我省丘陵、平湖稻区,中稻病害中以白叶枯病的流行频率高,为害损失重。经过多年的防治实践,采取种、肥、水、药四结合的综合防治技术,是能够控制到“有病无灾”的程度的。其中抗病品种的应用是综防技术之首。在当前“两高一优”农业生产中,如何加强示范、推广“优质、多抗、高产”新品种,是水稻生产发展中的重大课题。为此,我站对当前新引进、示范的中稻新品种(系),进行了对白叶枯病的抗病性鉴定,为扩大示范、推广提供科学依据。现简报如下,供参考。
In our province hills, Pinghu rice, rice disease blight epidemic high frequency, damage heavy loss. After many years of prevention and treatment practice, adopting a comprehensive prevention and control technology combined with species, fertilizer, water and medicine is able to control the degree of “sickness and disaster free”. Among them, the application of disease-resistant variety is the first in comprehensive prevention technology. In the current “two high and one excellent” agricultural production, how to strengthen demonstration and promote “high quality, multi-resistant and high yield” new varieties is a major issue in the development of rice production. To this end, I station on the new introduction, demonstration of new varieties of rice (lines), the resistance to bacterial blight identification, in order to expand the demonstration and promotion to provide a scientific basis. Now briefings are as follows for reference.
