摘　　要：试验使用0.5%噻苯隆可溶性液剂稀释1000、1500、2000、2500倍液,分别在饲草玉米苗期和大喇叭口期各进行1次喷雾处理,研究植物生长调节剂噻苯隆对饲草玉米株高和产量的影响,以明确其适宜用量,为饲草玉米增产提质提供新技术。结果表明,不同剂量的0.5%噻苯隆可溶性液剂对饲草玉米株高和生物产量均具有显著促进作用,且剂量越高作用越明显,其中,以0.5%噻苯隆可溶性液剂1000倍液效果最佳,饲草玉米株高与生物产量较对照分别增加6.54%、19.56%,且对饲草玉米安全,可以在生产上推广应用。In the experiment,0.5%Thidiazuron solution was used to dilute 1000,1500,2000,2500 times liquid,and 1 spray treatments were carried out in the forage corn seedling stage and the big bell stage,respectively.The effects of plant growth regulator Thidiazuron on the plant height and yield of forage corn were studied,and the suitable amount was determined to provide new technology for yield and quality improvement of forage corn.The results showed that different dosage of 0.5%Thidiazuron soluble liquid had a significant promotion effect on the plant height and biological yield of forage corn,and the effect became more obvious with the increase of the dosage.Among them,0.5%Thidiazuron soluble liquid 1000 times solution had the best effect.The plant height and biological yield of forage corn increased by 6.54%and 19.56%compared with the control,respectively.The test dose was safe for forage corn and could be used in production.
