黄腐酸钾定位施肥对棉花产量及品质性状的影响
Effects of Located Applying Fulvic Acid Potassium on Cotton Yield and Fiber Quality Traits
摘要
Abstract
[Objective]The research aimed to find optimum fulvic acid potassium (FAP) amount to improve cotton yield and fiber quality. [ Method] Adopting randomized block design, 6 treatments were designed, CK:no fertilizer, F:chemical fertilizer 750 kg/hm2 ,F+H1:chem-ical fertilizer 750 kg/hm2 added FAP 75 kg/hm2 ,F+H2:chemical fertilizer 750 kg/hm2 added FAP 150 kg/hm2 ,F+H3:chemical fertilizer 750 kg/hm2 added FAP 300 kg/hm2 ,F+H4:chemical fertilizer 750 kg/hm2 added FAP 450 kg/hm2 . Plant height, fruit branches number, boll numbers, boll weight, lint percentage, cotton yield and fiber quality were investigated in a location test for 4 years. [ Result] Chemical fertilizer added fulvic acid potassium prompted cotton vegetative growth and fruit growth in late growth stage. With the increase of FAP amount the autumn bolls and its proportion also increased, and the same for boll number per plant, cotton yield and lint yield. Compared with F treat-ment cotton yield of F+H1, F+H2, F+H3, F+H4 treatments was increased by 3. 3％,5. 4％,5. 2％and 9. 0％ respectively. FAP im-proved cotton fiber quality, especially increased the spinning consistency index significantly. [ Concluion] Chemical fertilizer added FAP 450 kg/hm2 could increase cotton yield effectively and improve cotton fiber quality.关键词
