近日来,我们接到不少电话,一致反映直播稻田很多稻苗出现心叶叶子紧紧地卷在了一起,要求植保站派人现场处理,并询问采取什么办法能防止再产生。通过现场观察和调查分析,这是直播稻田使用二氯喹啉酸及其混配剂产生的药害造成症状——“葱管叶”。 In recent days, we have received many phone calls, which consistently reflect the fact that many rice seedlings in the direct-broadcast rice paddy are tightly entwined with the leaves of the heart and require plant protection stations to send people to the site for treatment. They also ask what measures can be taken to prevent them from happening again. Through on-site observation and investigation and analysis, this is the symptom ------ “Onion leaves” produced by direct quarantine in rice fields using quinclorac and its mixture.
