旱育秧是水稻生产中普遍采用的育秧方式,但在实际操作中立枯病发生危害是粮农最烦恼的事。因为立枯病是旱育秧生产中发生最多、最容易造成毁灭性灾害的一种病害。它是由真菌引起的一种传染性病害,发生这种病害最终使粮农造成秧苗数量减少,品质下降,甚至全部枯死,影响稻谷生产。 Dry-raising seedling is commonly used in rice production methods of raising seedlings, but in practice the occurrence of damping-off disease is the most troublesome thing for farmers. Because blight is the most frequent occurrence in dry-seedling production, it is most likely to cause a devastating disaster. It is a contagious disease caused by fungi. The occurrence of this disease will eventually cause the number of seedlings to be reduced, the quality of the crops to be reduced or even all of them to die, which will affect the rice production.
