持力硼、速乐硼在油菜上应用效果

油菜基施持力硼与叶面喷施速乐硼相结合,对油菜生长、干物质累积和结实率提高有明显促进作用,能大幅度提高油菜产量。施硼处理组与对照组相比,苗期地上部和地下部干重分别增加了56.8%、34.7%;蕾薹期薹高、叶片数、最大叶长和叶宽分别增加了42.7%、16.4%、38.0%和46.9%;收获期整株角果鲜重、干重和油菜子增产率分别增加了82.6%、83.9%和35.2%。在缺硼土壤上,油菜施硼效应与土壤有效硼含量呈显著线性相关,而过量施用硼肥会导致油菜产量降低。

Application Effect of Granubor and Solubor in Rape

The rape growth was promoted when granubor was applied as basal fertilization and solubor sprayed as leaf fertilization.Accumulation of dry matter was promoted;and rate of bearing fruit was increased.The yield of rape seed was also obviously increased.Compared to the control,the dry matter of rape seedling above and under the ground was increased by 56.8% and 34.7%,respectively.Plant height,the number of leaf,the length of leaf maximum and the width of leaf was increased by 42.7%,16.4%,38.0% and 46.9% in the bolting stage of rape,respectively.Fresh and dry weight of silique,yield of rape seeds was increased by 82.6%,83.9% and 35.2% in the maturing stage.Boron effect on rape had significant linear correlation with the soil available boron content;but the yield of rape seeds would be decreased when boron fertilizer was excessively applied in boron lacking soil.
