甲黄隆在我区示范推广应用已有三年,面积逐年扩大,1991年冬至1992年春使用面积达14.39万亩,占大麦播种面积50.49％。三年来实践证明:甲黄隆是苗后较理想的除草剂,除草效果均在85％以上。但据报道,磺酰脲类的甲黄隆持效期长,如连续使用,其残留对后茬水稻和某些经济作物有药害,但对各类作物的耐药程度和前季(麦)作物的极限用量未见报道。为此,郊区农林局农技站于1992年特作本试验。现将结果初报如下。
Jialong Long demonstration and application in our area has been three years, the area has expanded each year, the winter of 1991 to the spring of 1992 the use of an area of 14.39 hectares, accounting for 50.49% of barley sown area. Three years proved that: Jia Huang Long after the seedling is the ideal herbicide, weeding effects are more than 85%. However, it has been reported that sulfonylurea long-acting persimmon, such as continuous use, the residue of rice and some cash crops crop injury, but the degree of resistance to various crops and the previous season (wheat The maximum amount of crop has not been reported. To this end, suburban Agriculture Bureau Agricultural Technology Station in 1992 special for the test. Now the results reported below.
