近几年,我县晚粳种植面积较大,每年约60万亩,占晚稻总面积60％左右。但由于后期青枯死秆较严重,对产量影响较大。为了剖析其原因,从中找出防治措施,我们进行了较广泛的田间调查,现将情况综述如下: 一、青枯死秆与产量的关系 晚粳青枯死秆主要出现在乳熟至黄熟阶段,一般低温冷害后表现突出,主要表现为叶片 In recent years, our county has a large area of ​​late japonica rice planting, about 600,000 mu per year, accounting for 60% of the total area of ​​late rice. However, due to the late dry dead straw more serious, a greater impact on the yield. In order to analyze its causes, to find out the prevention and control measures, we conducted a more extensive field investigation, the situation is summarized as follows: First, the relationship between the death of the stubble and yield of late Japonica late blight occurs mainly in the milk cooked to yellow stage, After chilling injury outstanding performance, mainly for the leaves
