摘要: 在棉花苗期施用多效唑对棉花生长发育、棉花产量和纤维品质有明显的影响。在300ppm以内,施用多效唑能在一定程度上抑制棉苗的生长,但可在中、后期促进棉株的发育,使棉株提早现蕾,进而提高棉花产量,改善纤维品质。在施用技术上,用多效唑浸种和在不同苗龄期喷施应使用不同的浓度。

Abstract: Appying multi-effect triazole (MET) in cotton seedling stages has evident effeets on the growth and development of the cotton plant, the cotton yield and fiber qualities. Within 300 ppm, applying MET can in some degrees inhibit the growth of cotton seedlings in the prior stage, but may improve the late development of cotton so that cotton buds emerge earlier and the cotton yield and fiber qualifies get better. When steeping cotton seeds and spraying in different seedlingages with MET, the different concentrations should be taken into account.

Key words: COTTON, MULTI-EFFECT TRIAZOLE, APPLYING IN SEEDLING STAGE, EFFECTS OF APPLYING TECHNIQUES, PLANT GROWTH REGULATING SUBSTANCES, SEEDLING
