根据試驗結果,用氯化苦进行土壤消毒对防治棉花黄萎病和枯萎病均有较好的效果。药剂消毒的有效距离与用药量成正相关,用药量每穴5毫升,其水平方向的有效距离为10—20厘米,10毫升为20—30厘米,作用范围可达土深30—40厘米。施药后覆盖土面,可以消灭土表的病菌,不覆盖则对土面的病菌无效。田間防治試驗的初步結果表明,应用氯化苦进行成片的土壤消毒,处理区黄、枯萎病株均低于前一年的发病基数及同年的对照区。用氧化苦消灭大田零星发病地点,效果可达89.3％。
According to the test results, soil disinfection with chloropicrin has a good effect on preventing and treating cotton verticillium wilt and fusarium wilt. Pharmacy disinfection effective distance and dosage is positively related to the dosage of 5 ml per hole, the horizontal effective distance of 10-20 cm, 10 ml to 20-30 cm, the role of up to 30-40 cm soil depth. After coating the soil surface, you can eliminate bacteria on the surface of the soil, the soil is not covered by the bacteria invalid. The preliminary results of field control trials showed that applying chloropicrin to the soil disinfection, the area-treated yellow and wilt strains were lower than the incidence of the previous year and the control area of the same year. With oxytocin destroy field sporadic incidence of up to 89.3%.
