以低肥力缺硼的棕壤进行田间和盆栽试验.结果表明,花生各生育期硼含量和各器官中硼的分布规律是:苗期茎叶>结荚盛期茎叶>收获期茎叶.茎叶>籽粒>荚果>荚壳.植株吸硼量与土壤速效硼量及硼肥用量均呈正相关.由于花生苗期吸硼量最多,施用硼肥宜早,亩施硼砂0.276kg.
Field experiment and pot experiment were carried out on low-fertility brown earth lacking boron, and the results showed that the boron content and the distribution of boron in different organs of peanut in different growth stages were as follows: stem and leaf at seedling stage> stem and leaf at harvesting stage> stem and leaf at harvesting stage. Stems and leaves> seeds> pod> pod shell.The amount of boron sorption in plants was positively correlated with available boron and boron fertilizers.Because of the most amount of boron in peanut seedling, boron fertilizer should be applied as early as 0.276kg.
