在水稻种植过程中,往往在长势正常的情况下忽然有植株下部叶片出现赤褐色斑点,上部新叶先褪绿,过段时间也出现赤褐色斑块,远望像“火烧”一样,一片赤枯,故称为赤枯病。赤枯病属生理性问题,不是病原微生物引起的,所以不需要使用杀菌剂,只有从科学调控水肥,改善生长环境,调理植株抗逆性等多方面入手,采取综合措施,才能取得好的效果。诱发水稻赤枯僵苗的原因很多,常见的有以下几种。一是长期深水浇灌。这类田块往往地势低洼,长期积水,导致土 In the process of rice cultivation, often under the condition of normal growth, the lower leaves of plants suddenly appear auburn spots, the upper part of the new leaves first become chlorotic, and there are also auburn patches over a period of time. The distance looks like a “fire” like a piece of red Withered, it is called red wilt. Blight is a physiological problem, not caused by pathogenic microorganisms, so do not need to use bactericides, only from the scientific control of water and fertilizer, improve the growth environment, stress tolerance and other aspects of plant to start, to take comprehensive measures to achieve good results . Red rice seedlings caused by a lot of reasons, there are several common. First, long-term deep-water irrigation. Such plots are often low lying, long-term water, leading to soil
