大麦条纹病是全国种大麦区常见病害,在我区不论山区川区发生逐年加重,此病是以种子带菌为传播来源。春天,播下种种发芽后,病菌浸入幼苗,逐渐蔓延到叶部造成危害,抽穗后病株上分生孢子随风传播,由花部侵入菌丝体潜藏在颖片与种皮之间,如遇低温高湿、日照少,植株不抽穗或抽穗不结实造成大麦减产。我们在农场和农村经三年试验和初步摸索出一些防治办法取得了成效。
Barley stripe disease is a common disease of barley species in the country, regardless of the occurrence of mountainous areas in Sichuan District increased year by year, the disease is based on the transmission of seed carriers. In spring, after sowing all kinds of germination, the germs invade the seedlings and gradually spread to the leaves, causing the damage. After the heading, the conidia on the diseased plants are spread by the wind, and the mycelia invaded by the flowers reach between the glumes and the seed coat. Case of low temperature and humidity, less sunshine, plants are not heading or heading is not strong barley yield. After three years of trial and initial exploration in the farms and rural areas, some preventive measures have achieved results.
