【摘要】 为了进一步研究SOD液肥对小麦生长发育和产量构成因素的影响,试验利用不同浓度SOD液肥在小麦拔节期对其进行叶面喷施试验,稀释浓度分别为100、300、500倍液,以喷施等量清水作对照。结果显示:①喷施SOD液肥能促进小麦光合作用及干物质积累,达到增产效果;②在拔节期叶面喷施3种不同浓度的SOD液肥有不同的肥效,处理2比对照增产19.55%,处理1比对照增产13.13%,处理3比对照增产6.28%。表明叶面喷施SOD液肥是一项简单易行、回报率相对较高的增产措施,在小麦高产高效栽培方面属一项实用技术,有较高的推广应用价值。更多还原

【Abstract】 Different concentration of SOD liquid fertilizer(CK,100,300,500 times dilution) was applied on wheat in jointing stage by foliage spraying in order to study its effects on wheat growth and yield components.The results showed that spraying SOD liquid fertilizer could promote the photosynthesis and dry matter accumulation which resulted in yield increasing.Different concentration of SOD liquid fertilizer had different effect on yield,as the yield was increased by 13.13%,19.55% and 6.28% compared with CK in 100,300,500 times dilution of SOD liquid fertilizer treatment respectively.Foliage spraying of liquid fertilizer SOD was a simple stimulation with high input-output ratio.更多还原
