摘要
为探究复合寡糖对山东典型作物产量的影响,本试验通过设置小麦拌种及不同时期喷施复合寡糖、玉米浸种及不同时期喷施复合寡糖多种处理。结果表明:在山东岱岳区,拌种条件下小麦花期+返青期喷施处理效果好于花期喷施或返青期喷施,但差异不显著;桓台县拌种条件下,返青期喷施、花期喷施、返青+花期喷施效果均好于只拌种处理,以拌种+花期喷施效果最好;不拌种的条件下,返青期喷施、花期喷施、返青期+花期喷施效果均好于对照,以花期喷施增产效果最好。不浸种条件下,两地玉米喷施复合寡糖处理的产量均高于不浸种处理,其中岱岳区花期+灌浆期喷施处理的产量及经济效益最高,桓台县灌浆期喷施处理的产量及经济效益最高。浸种条件下,岱岳区花期+灌浆期喷施处理的产量及经济效益最佳,桓台县苗期+灌浆期喷施处理的产量及经济效益最佳。综上所述,复合寡糖可显著增加作物产量及经济效益,就本地区而言,小麦可选择拌种处理+花期喷施,玉米可选择在拌种处理条件下,苗期或花期+灌浆期喷施。
To examine the impact of compound oligosaccharides on crop yield in Shandong,we conducted an experiment with various treatments,including mixing wheat seeds with compound oligosaccharides and spraying compound oligosaccharides at different stages,as well as soaking corn seeds and spraying with compound oligosaccharides at different stages.In Daiyue District,Shandong Province,wheat spraying at the flowering+regreening period under seed-mixing conditions exhibited superior efficacy compared to spraying solely at the flowering or regreening period,but the difference was not significant.In Huantai County,under seed-mixing conditions,spraying at the regreening period,flowering period,and regreening+flowering period outperformed seed-mixing treatment,with the most favorable outcome observed with seed-mixing+spraying at the flowering period.Conversely,without seed mixing,spraying at the regreening period,flowering period,regreening+flowering period all surpassed the control,with the highest yield increase achieved through spraying at the flowering period.Spray treatment of compound oligosaccharides resulted in higher yields compared to non-soaking methods,with Daiyue District and Huantai County achieving the highest yield and economic benefit during the flowering+filling period and filling period,respectively.When seeds were soaked,the combination of spray treatment during the flowering and filling period yielded the best results in Daiyue District,while the seedling and filling period were most effective in Huantai County.Compound oligosaccharides can substantially enhance crop yield and economic returns.In this region,wheat benefits from seed mixing with compound oligosaccharides combined with spraying at the flowering stage,while maize shows improved outcomes with spraying during the seedling or flowering+filling period,following seed soaking treatment.
