以’寒富’为试材,研究了套餐肥和常规施肥对苹果树体生长发育、果实产量和品质的影响。结果表明:与常规施肥相比,套餐肥处理的土壤有机质、碱解氮、速效磷、速效钾、有效钙和有效镁的含量分别提高了12.2%、8.0%、11.4%、14.8%、14.9%和31.5%。与常规施肥相比,施用套餐肥的’寒富’树体高度和干径分别增加了7.3%和5.8%;新梢长度和单株新梢数量分别提高了8.3%和20.4%;叶面积、比叶鲜重和干重及叶绿素含量增幅分别为2.9%、7.1%、1.9%和3.4%;苹果叶片的N、P、K和Ca含量分别增加了9.3%、23.0%、55.6%和60.9%;果实着色指数、花青苷含量、维生素C含量、果肉硬度和可溶性固形物含量分别增加了7.1%、10.2%、5.7%、4.3%和9.3%;花序数量增加了14.1%;’寒富’产量显著提高,平均每667 m~2产量增加300.6 kg。
Taking ’Hanfu’ as experimental material, the effects of package fertilizer and conventional fertilization on apple tree growth, fruit yield and quality were studied. The results showed that the contents of soil organic matter, available nitrogen, available phosphorus, available potassium, available calcium and available magnesium increased by 12.2%, 8.0%, 11.4%, 14.8% and 14.9% compared with conventional fertilization, And 31.5%. Compared with conventional fertilization, the height and dry diameter of ’Hanfu’ trees increased by 7.3% and 5.8%, respectively. The length of shoots and the number of shoots per plant increased by 8.3% and 20.4%, respectively. Leaf area, The fresh weight, dry weight and chlorophyll contents of the leaves increased by 2.9%, 7.1%, 1.9% and 3.4%, respectively. The content of N, P, K and Ca in apple leaves increased by 9.3%, 23.0%, 55.6% and 60.9% ; Fruit color index, anthocyanin content, vitamin C content, pulp hardness and soluble solids content increased by 7.1%, 10.2%, 5.7%, 4.3% and 9.3% respectively; the number of inflorescence increased by 14.1% Output increased significantly, with an average increase of 300.6 kg per 667 m ~ 2 output.
