多效唑(MET)是一种新型植物生长延缓物质,属三唑类化合物,具有调整水稻株型,防治病害,抑杀杂草,增强水稻抗逆性和提高产量等功能。渤海稻区普遍存在苗期低温冷害,土地盐碱含量高,分蘖期水源不足,水质差等问题,影响水稻产量,春稻应用多效唑,旨在提高秧苗素质,增强分蘖期抗旱和抗盐碱能力,以及成株期的抗倒伏能力,优化
Paclobutrazol (MET) is a new plant growth retarding substance, which belongs to triazole compounds. It has the functions of regulating rice plant type, preventing and controlling diseases, restraining weeds, enhancing rice stress resistance and increasing yield. In the Bohai Sea rice area, low temperature and cold damage at seedling stage, high content of salinization in soil, insufficient water source at the tillering stage and poor water quality are common problems in paddy rice area, and the application of paclobutrazol in spring rice is aimed at improving the quality of seedlings and enhancing the drought resistance and salt-alkali resistance at tillering stage , And adult lodging ability, optimization
