摘要
本文对稀禾定土壤处理的生物活性和除草效果进行了研究。室内试验表明,稀禾定土壤处理具有较强的生物活性,其碱性药液土壤处理后生物活性更高,持效期也明显延长。田间试验表明,稀禾定碱性药液做土壤处理剂,防除大豆、番茄田全生育期杂草,除草效果稳定。建议施药量为225升/公顷。
The bioactivity and herbicide effect of sethoxydim by soil treatment were studied in this paper.The results of laboratory experiment and field trials showed that good bioactivity of sethoxydim by soil treatment was obtained.The alkaline solution of sethoxydim showed a better bioactivity,and its residual effect was prolonged significantly.Being used as a soil treatment agent,the alkaline solution of sethoxydim gave a stable effect on controlling weeds in soybean and tomato field,the recommended dosage of it was 2.25l/ha.
