浙江水稻土有效同含量0—1.77mgkg-1,平均为0.30mgkg-1,低于油菜缺硼临界值。油菜施硼平均每亩增产油菜籽15.8公斤,增产16.7%;缺硼和严重缺硼区施用硼肥分别增产10%—20%和30%以上,轻度或潜在缺硼区增产在5%—10%.土壤有效硼含量、土壤湿度、油菜品种、有机肥料以及氮磷肥用量等都影响硼肥的施用效果。苗期叶面喷施和作基肥的效果较好。
Zhejiang paddy soil with the effective content of 0-1.77mgkg-1, an average of 0.30mgkg-1, lower than the threshold of boron deficiency in rapeseed. Rapeseed rape average yield of rapeseed 15.8 kg per mu, an increase of 16.7%; boron deficiency and boron deficiency severely boron-deficient areas were increased yield of 10% -20% and 30%, mild or potentially boron deficiency area yield At 5% -10%. Soil available boron content, soil moisture, rapeseed varieties, organic fertilizers and nitrogen and phosphorus fertilizers all affect the application of boron fertilizers. Seedling foliar application and as a base fertilizer better.
