硼主要存在于植物的分生组织和生殖器官中,适时适量施用硼肥,有利根系正常生长和花器形成发育,可有效防止油菜“花而不实”,柑桔“果而不硕”(石头果)和小麦“穗而不稔”,从而促进了产量的提高。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。一、我省农田土壤的硼素概况 Boron is mainly found in plant meristematic organs and reproductive organs. The proper amount of boron fertilizer applied in a timely manner is beneficial to the normal growth of root system and the development of flower organ, which can effectively prevent rape from “blooming” and citrus “fruit rather than large” (stone Fruit) and wheat “spike but not stagnant”, thus contributing to the increase of yield. In recent years, our province agricultural research and other units made a lot of research on boron fertilizer, are consolidated under the next. First, the boron content of agricultural soil in our province
