| 摘 要： | 应用二次通用旋转组合设计,在砂壤质棕漠土上进行了葡萄滴灌施肥条件下的氮、磷、钾追肥配比试验,获得了相应的函数模型;通过对模型的优化和解析,得出了葡萄适宜的NPK滴灌追肥用量配比,在葡萄萌芽—开花期滴灌追施氮、磷、钾的比例以N∶P2O5∶K2O=1:0.26:0.12为好,在葡萄果实生长期滴灌追施氮、磷、钾的比例以N∶P2O5∶K2O=1:1.54:1.97较佳。

| Abstract: | By means of the quadratic universal rotatory combination design, corresponding function model was obtained by field experiment of ratio of top-dressing of N, P, K for grape under the condition of drip fertilization. The optimum ratio of drip top dressing of N, P , K was educed by optimizing and parsing the model .The ratio of NP_2O_5K_2O was 1:0.26:0.12 in vegetative stage and 1:1.54:1.97 in fruit-growing period. |
