针对44%单嘧·扑灭WP(谷友)在推广中出现药害的问题,采用正交试验方法,对施药剂量、喷灌水量、整地质量、土壤墒情、喷灌时间和杂草种类6个影响因素进行比较试验,研究使用44%单嘧.扑灭WP的不安全因素。结果表明:影响44%单嘧·扑灭WP安全性的最重要因素是施药剂量,其次是喷灌水量、土壤墒情、整地质量等。确定了谷田使用44%单嘧·扑灭WP的优化技术方案和不安全因素。优化技术方案为:施药剂量1200 g/hm2,整地平整,土壤含水量15%,药后不喷灌;不安全因素即禁忌事项为:施药剂量2400 g/hm2,喷灌水量35 mm,整地疏松不平,土壤含水量≤10%,药后进行喷灌。
Aiming at the problem of phytotoxicity in the popularization of WP (GuYou) by 44% monomethylpyrazole, orthogonal test was used to influence the application dose, watering quantity, soil preparation quality, soil moisture, irrigation time and weed species Factors were compared to study the use of 44% monopirox. Fight WP insecurity. The results showed that the most important factor influencing the safety of WP with 44% mononuclear is spraying dose, followed by spray irrigation, soil moisture, soil preparation and so on. To determine the use of 44% Montagne suppression of WP optimized technology solutions and insecurity. The optimized technical scheme is as follows: the dosage is 1200 g / hm2, the soil is leveled and the soil moisture content is 15%, the sprinkler is not sprayed after the pesticide is applied. The unsafe factors are taboo items: spraying dosage 2400 g / hm2, spraying water 35 mm, Uneven, soil moisture ≤ 10%, sprinkler irrigation after treatment.
