施锌方式对辽东南地区玉米干物质生产及产量形成的影响
The Effect of Zinc on Maize Dry Matter Production and Grain Yield in the Southeast Region of Liaoning Province
摘要
Abstract
A field experiment was conducted using maize hybrids Zhengdan958 and Danyu801,to understand the effect of Zinc fertilizer foliar spray,Zinc fertilizer soil application and Zinc fertilizer application +foliar spray on maize dry matter production,accumulation and grain yield in southeast region of Liaoning province. The results showed,zinc foliar spray had little affects on maize yield,both Zinc fertilizer soil application and soil application+foliar spray decreased unbarred length of ear and unbarred plant number,increased kernel number per ear,eventually improved maize grain yield.Zinc fertilizer improved maize dry matter(DM)pro-duction and accumulation and increased DM accumulation amount,while has little effect on the ratio of post-silking DM amount(Post DM)to total dry matter(total DM)amount at maturity stage and harvest index (HI).There was no significant difference between the effects of soil application and soil application +foliar spray on maize dry matter production and grain yield.Thus we can conclude that,in the southeast region of Liaoning,soil application Zinc fertilizer was an economical way to meet the maize demand for Zinc in the view of field production practice.关键词
