Effects of superfine activated phosphorus fertilizers on growth and phosphorus utilization of pakchoi

为减少磷肥在土壤中的固定损失，提高其有效性，增加作物产量，通过小白菜盆栽试验，研究不同超微细活化磷肥对小白菜产量、品质、土壤养分以及肥料利用率的影响。本试验以不施肥和常规施肥为对照，设置磷肥与钾肥、腐植酸、沸石粉、硅藻土不同搭配并进行超微细化处理。结果表明：超微细活化磷肥处理均显著提高了小白菜的产量，增产率达0.44%~12.82%；与氮磷钾常规施肥处理相比，超微细磷钾-腐植酸-硅藻土-沸石粉活化处理小白菜的Vc含量增加了5.37%，硝酸盐含量降低了18.23%，可溶性糖含量降低了53.13%，土壤有效磷含量提高了17.20%~24.87%，磷肥利用率提高了3.28~8.47个百分点。在本试验...

Summary:为减少磷肥在土壤中的固定损失，提高其有效性，增加作物产量，通过小白菜盆栽试验，研究不同超微细活化磷肥对小白菜产量、品质、土壤养分以及肥料利用率的影响。本试验以不施肥和常规施肥为对照，设置磷肥与钾肥、腐植酸、沸石粉、硅藻土不同搭配并进行超微细化处理。结果表明：超微细活化磷肥处理均显著提高了小白菜的产量，增产率达0.44%~12.82%；与氮磷钾常规施肥处理相比，超微细磷钾-腐植酸-硅藻土-沸石粉活化处理小白菜的Vc含量增加了5.37%，硝酸盐含量降低了18.23%，可溶性糖含量降低了53.13%，土壤有效磷含量提高了17.20%~24.87%，磷肥利用率提高了3.28~8.47个百分点。在本试验条件下，推荐在肥料生产和施用中选择超微细磷钾-腐植酸-沸石粉活化处理的肥料。 To reduce the soil fixing of phosphorus fertilizer, improve the nutrition efficiency, and increase crop yield, the potted pakchoi experiment was conducted to study the effects of fertilizer on the yield and quality of pakchoi, soil nutrients and fertilizer use efficiency. In this study, we set up a control, a conventional fertilizer treatment and seven novel phosphorus fertilizers that combined with humic acid, zeolite powder, diatomite activator in different proportions. The results showed that, several optimized phosphorus treatments significantly increased the yield of pakchoi with increase rate from 0.44% to 12.82% Compared with nitrogen, phosphorus and potassium regular f
