用100倍高效硼镁肥柑桔叶面喷施坐果率比喷清水平均提高3.2%;单株产量比喷清水平均提高10.5kg,增产33.49%;并能显著改善品质,对提高柑桔果实可溶性固形物、总糖、维生素C,降低酸度有明显促进作用。每667m2成本4.5元,高效硼镁肥比等值硼砂每667m2多收果348kg。
100 times the efficiency of boron and magnesium fertilizer citrus foliar spray rate was 3.2% higher than the spraying level; per plant than spraying level were increased by 10.5kg, an increase of 33.49%; and can significantly improve the quality of citrus fruit to improve soluble Solid, total sugar, vitamin C, reduce acidity significantly promote the role. Each 667m2 cost 4.5 yuan, efficient boron and magnesium fertilizer than the equivalent borax 667m2 more fruit 348kg.
