马铃薯“3414”肥料效应试验
|
摘要
通过马铃薯"3414"肥料效应试验的三元二次回归方程,计算理论上的氮、磷、钾最佳施肥量。结果表明,结合生产实际,推荐青海省湟中县马铃薯主导品种的最佳施肥量为纯N 73.64 kg/hm~2、P_2O_5103.73 kg/hm~2、K_2O 76.99 kg/hm~2。马铃薯苗期、现蕾期、盛花期植株干重增加缓慢,差异较小,进入块茎膨大期后植株干重迅速增加,膨大期与成熟期块茎干重增加较根、茎、叶快,占全株总干重的59%~69%,与形成高产直接有关。
The theoretic optimum amount of fertilization was calculated using the quadratic regression equation on three factors combined with the "3414" experiment.The results showed that combined with the actual production,the optimum amount of fertilization was N 73.64 kg/hm~2,P_2O_5 103.73 kg/hm~2,K_2O 76.99 kg/hm~2.Potato plant dry weight increased slowly in seedling,squaring period,flowering,the difference is not significant.Plant dry weight increased rapidly after tuber enlargement stage,tuber dry weight increased more quickly than root,stem and leaf,accounted for the total dry weight of 59%~69%,it have direct relation with high yield.
