雨水过多的时候,容易造成田间苗木根系长时间浸泡在水中,无氧呼吸过甚,严重影响根系的发生,抗病能力大幅下降,容易导致根系病害发生。特别是扦插苗,根系本身就比较脆弱,更容易导致病害的暴发。由于田间湿度高,也容易导致各种烂叶病(炭疽、叶斑病、细菌性叶斑病)的发生。可按苗木病情,采用以下措施:一、防治根腐病、立枯病配方1.24%满穗3包+美国大宝4包
When the rain is too much, it is easy to cause the seedling roots in the field to soak in the water for a long time. The anaerobic respiration is too serious, which seriously affects the occurrence of the root system. The disease resistance greatly decreases and the root disease easily occurs. In particular, cutting seedlings, the root itself is more vulnerable, more easily lead to disease outbreaks. Due to the high humidity in the field, it is also easy to cause various rotten leaf diseases (anthrax, leaf spot, bacterial leaf spot). According to seedlings disease, the following measures: First, the control of root rot, damping-off disease formula 1.24% full 3 bags of American treasure 4 bags
