蔺草田因长期使用化学除草剂绿磺隆,造成在土壤中残留,严重抑制了后茬晚稻等作物生长,导致僵苗而减产。使用僵苗丰、绿芬威4号、磷酸二氢钾、九二○等微肥和生长调节剂,在晚稻苗期喷施2~3次后,能明显地恢复受害晚稻的生长,株高、穗长、分蘖均表现有一定程度增加,有明显的增粒及增穗作用,增产幅度为25.8%~1.5%,平均增产12.5%。 Rush grass because of long-term use of chemical herbicide chlorsulfuron, resulting in residual in the soil, seriously inhibited the late crop of late crop growth, leading to stiff seedlings and cut. The use of stiff Miao Feng, Green Fenwei 4, potassium dihydrogen phosphate, nine hundred and twenty other fertilizers and growth regulators in the late rice seedling spraying 2 or 3 times, can significantly restore the damaged late rice growth, plant height , Spike length and tiller showed a certain degree of increase, with significant increase of grain and ear by ear, yield increase of 25.8% to 1.5%, an average yield of 12.5%.
