喷施有机硒生物肥对陇东黄土旱塬春玉米产量及硒累积的影响
Effects of Foliar Application of Organic Selenium Bio-fertilizer on the Yield and Selenium Accumulation in Spring Maize on the Dryland Areas of Loess Plateau in Eastern Gansu
摘要
Abstract
To investigate the effects of foliar application of organic selenium bio-fertilizer on yield and selenium accumulation in spring maize on the Dryland of Loess Plateau in eastern Gansu,and to provide a reference for selenium-enriched maize production in this region,a field experiment was conducted using the maize variety Xianyu1483.Four application rates of organic selenium bio-fertilizer(120,240,360,720 kg/ha)were set as treatments.Results showed that foliar application of organic selenium bio-fertilizer significantly affected maize biomass yield,while the grain yield was not significantly influenced.The highest maize yield was observed at 240 kg/ha,with biomass and grain yields increased by 17.68%and 5.55%,respectively,compared to the water-sprayed control.Selenium content in both grain and straw increased significantly with higher fertilizer application,reaching 0.28 to 1.49 and 5.86 to 22.31 times compared to the control levels,respectively.In conclusion,foliar application of organic selenium bio-fertilizer promotes biomass yield and selenium enrichment in grain and straw of spring maize on the dryland of Loess Plateau,with the best effect observed at 240 kg/ha.关键词
