1964年晚造,全省各地都普遍试种了新育成的矮稈品种,由于对种性的了解不够,栽培经验不足,加上不良气候的影响,各种稻病,尤其是白叶枯病及黄矮病发生严重,损失很大。1965年晚造再度试种,情况有了好转,一般表现良好,产量较高,病害也相对减轻。为了及时总结验验,现将两年来有关矮种病害的调查研究及防治经验综合整理如下,以供生产和科研工作上的参考。 In late 1964, dwarf varieties newly bred were widely planted throughout the province. Due to lack of understanding of species, lack of cultivation experience and bad weather, various rice diseases, especially bacterial leaf blight And yellow dwarf disease serious, great loss. The trial was rebuilt in the evening of 1965 and the situation has been improved. Generally, the performance is good, the output is relatively high, and the diseases are lessened. In order to summarize the test in time, the investigation and prevention and treatment experience of the disease in the past two years are summarized as follows for the reference of production and scientific research.
