| 摘 要： | 根据59个氮磷钾肥效试验结果,研究了福建结球甘蓝氮磷钾施肥指标。结果表明,平衡施肥产量与空白区产量呈现线性正相关关系,土壤养分对结球甘蓝产量的平均贡献率为51.0%,施用氮磷钾平均增产40.4%、11.6%和15.0%;土壤速效氮磷钾高产临界指标分别为碱解氮207 mg/kg、Olsen-P 71 mg/kg和速效钾157 mg/kg;平均经济施肥量为N 238 kg/hm2、P2O5 70 kg/hm2和K2O 192 kg/hm2,三要素比例为1∶0.29∶0.81;土壤有效氮磷钾测定值与推荐施肥量之间满足指数回归方程,根据土壤养分测定值可推算结球甘蓝推荐施肥量,起到因土施肥的作用。

| Abstract: | Based on the results of 59 field experiments of kale cabbage response to N,P and K fertilization in recent years,NPK fertilization indices for head cabbage in Fujian Province were developed.The results showed that there were linear positive correlation between the yield applying balanced fertilization and the yield in blank.The average contribution rate of soil nutrients to yield of head cabbage was 51.0%,the average increased yield of N,P and K applications was 40.4%,11.6% and 15.0% respectively.The critic... |
