- 摘要:
- 为高效利用大豆田土壤封闭除草剂882 g·L-1丙炔氟草胺·精异丙甲草胺，2020-2021年采用随机区组试验设计方法进行田间药效试验。结果表明，除草剂882 g·L-1丙炔氟草胺·精异丙甲草胺可分散油悬浮剂用于大豆播种后出苗前土壤喷雾处理，在有效成分用量为1 058.4~2 381.4 g·hm-2的条件下，对大豆田稗草、藜、本氏蓼、苘麻、水棘针等主要杂草都有很好的防效。两年试验中供试药剂处理药后40 d对一年生杂草总草的株数防效和鲜重防效分别为92.9%~100.0%、92.3%~99.1%和94.8%~100.0%、95.5%~99.7%。在处理后的20和40 d及大豆封垄前，2020年最高剂量处理下有少量植株的心叶皱缩，其余各个处理均未出现药害症状。各药剂处理与空白对照相比大豆增产显著，增产率分别为202.8%~220.9%和181.6%~196.9%。适宜的施药剂量为882 g·L-1丙炔氟草胺·精异丙甲草胺可分散油悬浮剂制剂量1 200~1 500 mL·hm-2(有效成分用量1 058.4~1 323.0 g·hm-2)。
- Abstract:
- In order to efficiently utilize pre-emergence herbicide 882 g·L-1 flumioxazin·s-metolachlor oil-based suspension concentrates (OD) against annual weeds in soybean fields, field efficacy trials were conducted by randomized block method in 2020-2021. The results denoted that the herbicide 882 g·L-1 flumioxazin·s-metolachlor OD was used for the soil spray treatment of soybeans before emergence and had a good control effect on the primary weeds including Echinochloa crus-galli (L.) P. Beauv., Chenopodium album L., Persicaria bungeana (Turcz.) Nakai ex T. Mori, Abutilon theophrasti Medicus and Amethystea caerulea L. at the ingredient dosage of 1 058.4-2 381.4 g·ha-1. The plant control efficacy and fresh weight control efficacy on the total weed were 92.9%—100.0%, 92.3%-99.1% and 94.8%-100.0%, 95.5%-99.7%respectively. At 20 days and 40 days after treatment and before ridding, the heart leaves of a small number plants were crumpled under the highest dose treatment in 2020, and the other treatments displayed no phytotoxicity. The yield of soybean was significantly increased by each treatment compared with the blank control, and the rate of yield increase was 202.8%-220.9% and 181.6%-196.9%. The appropriate application dose of 882 g·L-1 flumioxazin·s-metolachlor OD is 1 200-1 500 mL·ha-1 (the effective component is 1 058.4-1 323.0 g·ha-1).
