为了探寻对栽培稻安全的杂草稻防除技术,南京农业大学植物保护学院等单位研究人员采用整株测定法研究了丙草胺对杂草稻的毒力及解草啶减轻丙草胺对栽培稻药害的应用技术,并通过田间试验检验了这一技术的安全性。结果表明:丙草胺在有效成分450g/hm2时,可显著抑制杂草稻和栽培稻的生长;采用30mg/L解草啶浸种48小时,可显著减轻丙草胺对栽培稻的药害,随着丙草胺施药量的增加,解
In order to explore the weedy rice prevention and control of rice cultivation technology, Nanjing Agricultural University, Plant Protection College and other units of researchers measured the toxicity of weedy mildew rice and the protective effect of acetochlor on the cultivation Rice injury application technology, and tested the safety of this technology through field experiments. The results showed that pretilachlor could significantly inhibit the growth of weedy rice and cultivated rice at the dosage of 450g / hm2. Soaking soaking 48 h with 30mg / L of glyphosate significantly reduced the phytotoxicity of pretilachlor to cultivated rice, With the increase of the amount of pretilachlor, solution
