结论由于叶面喷布磷酸、磷酸氢二钾、磷酸二氢钠、磷酸二氢钾和二磷酸四氢钙,桔苹果实中磷的浓度增加,但前三种材料伤害果点。最后两种材料的高容量喷布(2250升/公顷),使果实中磷的浓度相应增加4.3毫克/100克和5.3毫克/100克。在0℃、1.5℃、3.5℃的高湿
Conclusions The concentration of phosphorus in orange apple fruits increased due to foliar spraying of phosphoric acid, dipotassium hydrogenphosphate, sodium dihydrogenphosphate, potassium dihydrogenphosphate and calcium diphosphate, but the first three kinds of materials harmed the fruit. The last two materials were sprayed at a high volume (2,250 l / ha) to increase the phosphorus concentration in the fruit by 4.3 mg / 100 g and 5.3 mg / 100 g, respectively. High humidity at 0 ° C, 1.5 ° C, 3.5 ° C
