甘肃省景泰县胡麻田杂草发生消长规律研究
通过定点调查,研究了甘肃省景泰县胡麻田一年生杂草的发生消长规律。结果表明：胡麻田杂草从4月5日左右开始出苗,至5月12日全部出齐;杂草在4月28日出现1个出苗高峰,杂草的平均株高在胡麻成熟期达到最高;平均鲜重在胡麻盛花期达到最高。野燕麦的平均株高在胡麻成熟期达到最高,平均鲜重在胡麻盛花期达到最高;藜的平均株高和鲜重在胡麻成熟期达到最高。5月5～12日是防除胡麻田一年生杂草的适宜时期;防除野燕麦的最佳施药时期是4月28日～5月5日;防除藜的最佳施药时期是5月12～19日。...

| Notes | Through the location observation and investigation,the growth and decline rules of annual weeds in linseed field in Jingtai county of Gansu province were studied.The results showed that the emergence date of weed seedlings was from about April 5th to May 12th,and there was a weed seedling emergence peak on April 28th.The average plant height of weeds was the highest in the mature period of linseed,and their average fresh weight reached the highest in the full flowering period of linseed.The average plant height of oat grass was the highest in the mature period of linseed,and its average fresh weight reached the highest in the full flowering period of linseed.The average plant height and fresh weight of Chenopodium album achieved the highest in the mature period of linseed.The suitable control date of annual weeds in linseed field was from May 5th to May 12th.The optimum date of using herbicides to control oat grass was from April 28th to May 5th,and that of controlling Chenopodium album was from May 12th to M |
