麦积区花牛苹果氮磷钾最佳配比施肥试验

Experiment on the Optimum Ratio of N P and K Fertilization of Huaniu Apple in Maiji District

在甘肃省天水市麦积区马跑泉镇龙槐村以6年花牛苹果树为试材,于2020年10月开始进行了苹果氮、磷、钾最佳配比施肥试验。设置7个处理,依据苹果的性状、含糖量、硬度及产量数据分析,得出处理1的苹果配方施肥:每0.067 hm^(2)N为21.1 kg、P_(3)O_(4)为15 kg、K_(2)O为17.92 kg为最佳配比。

In Longhuai Village the experiment on the optimal ratio of nitrogen, phosphorus and potassium fertilization of apple trees is carried out in October 2020. Seven treatments are set up. According to the analysis of apple characters, sugar content, hardness and yield data, the formula fertilization of apple in T1 is obtained: N is 21.1 kg/0.067 hm^(2), P_(3)O_(4) is 15 kg/0.067 hm^(2), and K_(2)O is 17.92 kg/0.067 hm^(2).
