【摘要】 为验证保试达(200g/l草铵磷可溶性液剂)除草剂对茶园常见杂草防除效果,3月下旬至5月上旬在本所开展本次试验。试验结果表明:保试达3l/ha、3.75l/ha和4.5l/ha3种用药量防除牛繁缕、秋鼠麴草、鱼眼草、毛马塘、蓼5种主要靶标杂草均具有较好的速效性和持效性。保试达最低剂量3L/ha处理药后7天防除以上5种杂草的效果分别达到100%、100%、96.67%、100%和96.69%,药后35天对5种靶标杂草防除效果均为100%。保试达3种剂量处理防除牛繁缕、秋鼠麴草、蓼的速效性显著优于41%草甘磷水剂2.25l/ha处理,对毛马塘的速效性显著优于20%百草枯水剂2.7l/ha;持效性与两对照药剂处理相当。更多还原

【Abstract】 The effect of Basta(200g/l glufosinate-ammonium SL) on weed controlling in tea field was studied between March and May. The result shows: the three doses (3l/ha, 3.75l/ha and 4.5l/ha) of Basta have good fast-acting and lasting effect on Myosoton aquaticum, Gnaphalium hypoleucum, Dichrocephala integrifolia, Digitaria chrysoblephara, Polygonum longisetum and Polygonum. After 7 days the effects of the minimum dose of Basta (3l/ha) on the five target weeds were 100%, 100%, 96.6%, 100% and 96.69%; After 35 days the effects were all reach to 100%. The fast-acting of the three doses of Basta was significantly better on Myosoton aquaticum, Gnaphalium hypoleucum and Polygonum than 41% glyphosate AS 2.25l/ha, and was significantly better on Polygonum longisetum than 20% paraquat AS 2.7l/ha.更多还原
