摘要
为探究叶面喷施富硒水溶肥对水稻产量及稻米含硒量的影响,以鄄城县引马镇为试验地,探讨了叶面喷施富硒水溶肥的不同方案对水稻产量及稻米含硒量的影响.结果表明,叶面喷施富硒水溶肥可显著提高水稻生长状况,包括株高、穗长、分蘖数、穗粒数和结实率,分别提高11.96%、9.11%、7.16%、6.27%和5.98%,为提高水稻产量提供了有效支持;同时,叶面喷施富硒水溶肥还显著提高了水稻的产量和稻米硒含量,处理组D在百粒质量和产量方面表现最佳,增幅分别为15.41%和22.84%.叶面喷施富硒水溶肥在水稻生产中具有明显促进作用,为农业生产提供了一种可行的施肥方式,具有广阔的应用前景.
Abstract
In order to investigate the effects of foliar spraying of selenium rich water-soluble fertilizer on rice yield and selenium con-tent,the experiment was conducted in Yinma Town,Juancheng County,and the effects of different foliar spraying schemes of seleni-um rich water-soluble fertilizer on rice yield and selenium content were investigated.The results showed that foliar spraying of sele-nium rich water-soluble fertilizer can significantly improve the growth status of rice,including plant height,panicle length,tiller number,grain number per panicle,and seed setting rate,with an increase of 11.96%,9.11%,7.16%,6.27%,and 5.98%,respectively,providing effective support for improving rice yield.Meanwhile,foliar spraying of selenium rich water-soluble fertilizer significantly increased rice yield and selenium content.Treatment group D performed the best in terms of 100 grain quality and yield,with increas-es of 15.41%and 22.84%,respectively.Foliar spraying of selenium rich water-soluble fertilizer has a significant promoting effect on rice production,providing a feasible fertilization method for agricultural production and has broad application prospects.
