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
In order to further study the influence of SOD liquid fertilizer on the growth and yield components of wheat, the experiments were carried out by spraying different concentrations of SOD liquid fertilizer at the jointing stage of wheat at the dilution of 100, 300 and 500 times, respectively, The same amount of water as a control. The results showed that ① spraying SOD fertilizer could promote photosynthesis and dry matter accumulation of wheat and achieve the effect of increasing yield; ② spraying three different concentrations of SOD liquid fertilizer at jointing stage had different fertilizer efficiencies, yielding 19.55% Treatment 1 increased 13.13% of the control and treatment 3 increased 6.28% of the control. That foliar spray SOD liquid fertilizer is one
