硼主要存在于植物的分生组织和生殖器官中.据研究,植物的缺硼症状首先表现在根尖上,其影响根尖分生组织的细胞分化和伸长,致使根尖老化,根系不展;缺硼还使茎端生长迟滞,以至坏死,花器中花药、花丝不育,花粉管形成受阻,受精过程难以完成;等等.适时适量施用硼肥,有利根的正常生长,有利花器形成发育,可有效防止油菜“花而不实”柑桔“果而不硕”、小麦“穗而不粒”等病症,从而大大促进产量的提高.近几年来,我省农业科研等单位对硼肥作过许多研究,现综合整理于下:
Boron is mainly found in plant meristematic and reproductive organs.According to the study, the boron deficiency symptoms of plants first appear in the root tip, which affects the cell differentiation and elongation of the apical meristem, resulting in the root tip aging, the root does not show Boron deficiency also delayed the growth of the stem end, and even necrosis, anthers, filament sterility, pollen tube formation is blocked, fertilization process is difficult to complete; etc. Appropriate amount of application of boron fertilizers, root growth and conducive to the formation of development , Can effectively prevent the rape “flower but not real” citrus “fruit instead of Shuo”, wheat “spike instead of grain” and other diseases, thus greatly promoting the yield increase.In recent years, our province agricultural research and other units of boron fertilizer Many studies have been made, are summarized in the following:
