在棉花生长中、后期,用除草醚整枝,可以杀死或抑制无效嫩蕾、嫩芽、嫩叶(简称“三嫩”,下同),代替人工打边心、抹赘芽,使棉株养分集中用于棉铃的生长发育,以增加铃重,提高单产。这一试验我们连续进行了四年,1977、1978年的试验结果已经报道(本刊1979年第9期—编者)。但是除草醚整枝维持的有效期不长,一星期后“三嫩”便重新长出来。针对这一缺点,1980年我们进行了在喷第1次药液后的第8天,以同一浓度的药液喷第2次的试验。结果除草
In cotton growth, late, with weeding ether pruning, can kill or inhibit the ineffective buds, buds, young leaves (referred to as “three tender”, the same below), instead of artificial beading, wiping buds so that cotton Nutrient concentration for the growth and development of cotton bolls to increase boll weight and increase yield. We have conducted this trial for four consecutive years, and the results of the trials in 1977 and 1978 have been reported (Journal No. 9, 1979 - Editor). But weeding ether secures the validity of not long, a week later, “three tender” will be re-grown. In response to this shortcoming, in 1980, we conducted the second test on the eighth day after spraying the first chemical solution with the same concentration of chemical solution. The result weeding
