基于棉粕的氨基酸肥对小麦生长及产量的影响

摘要

为了明确基于棉粕的氨基酸肥对小麦生长发育的影响,采用田间试验,研究喷施清水、优多牌氨基酸水溶肥和棉粕腐氨基酸水溶肥对小麦不同生育时期生长指标及产量的影响.结果表明,与喷施清水处理和喷施优多牌氨基酸水溶肥处理相比,喷施棉粕氨基酸肥的小麦的株高、叶面积、叶绿素、干物质均有不同程度的提高,同时进一步促进了小麦的分蘖和成穗,使小麦产量显著增加,与喷施清水处理和喷施优多牌氨基酸水溶肥处理相比,增幅分别为15.2％和4.97％.%In order to identify the effect of amino acid fertilizer from cottonseed meal on growth and development of wheat,The effects of sprayed water,water soluble amino acid fertilizer(Youduo) and cottonseed meal rot amino acid water soluble fertilizer on the growth and yield of wheat at different growth stages were studied in field experiment.It turned out the wheat plant height,leaf size,chlorophyll and dry material increased by different degrees,and the wheat tillering as well as earing increased,too,which promoted wheat yield by 15.2％ and 4.97％ in the treatment of cottonseed meal amino acid fertilizer,compared with treatment of sprayed water and water soluble amino acid fertilizer(Youduo) respectively.
