多效唑(简称MET)是我国近期合成的具有先进水平的三唑类新型植物生长调节剂。通过抑制作物体内赤霉素的合成,减弱了顶端生长优势,促进生殖生长,对作物表现出控高、增叶、抗逆、防病、增产等多种效应。新乡市农技站和河南职业技术师范学院等单位,经过四年试验研究表明:多效唑在粮、棉、油、果、菜、花、桑等28种作物上表现出明显的增产效果。稀、麦、玉米增产10%,大豆、棉花增产10—15%,花生、红薯、绿豆增产15—30%,苹果、桃、洋葱增产50—100%。1989
Paclobutrazol (MET) is a new triazole plant growth regulator with advanced level recently synthesized in China. By inhibiting the synthesis of gibberellin in crops, the advantages of top growth are weakened, and reproductive growth is promoted. Various effects such as controlling high, increasing leaf, resisting stress, preventing diseases and increasing yield are observed. Xinxiang Agricultural Technology Station and Henan Vocational and Technical Teachers College and other units, after four years of experimental study showed that: paclobutrazol in grain, cotton, oil, fruit, vegetables, flowers, mulberry and other 28 kinds of crops showed significant increase in yield. The yield of lean, wheat and corn is 10%, that of soybean and cotton is 10-15%, that of peanut, sweet potato and mung bean is 15-30%, that of apple, peach and onion is 50-100%. 1989
