| 摘 要： | 田间试验条件下研究了不同磷肥品种在石灰性水稻田的当季施用效果及其后效.试验结果表明,在石灰性水稻田中施用过磷酸钙和钙镁磷肥,均可增强水稻分蘖能力,提早水稻物候期,增加水稻产量,从而提高经济效益.过磷酸钙对早稻的增产作用及对晚稻的增产效果都显著高于钙镁磷肥,并且,磷肥后效对晚稻增产效果随早稻施磷量增加而增加.可见,在石灰性水稻田的早稻施用过磷酸钙(P2O560～75 kg/hm2),是提高产量,充分发挥磷肥后效,提高磷肥利用率的一项有效措施.

| Abstract: | The effect of different phosphate fertilizers on calcareous rice soil were studied in field trial.The results showed that both single super phosphate and fused calcium magnesium phosphate used in calcareous rice field could enhance rice segregating,advance its the phenology time,increase the yield and improve the economic benefit.The effect of single super phosphate on increasing the production of prematurity rice and its effect on serotinous rice were more notable than that of fused calcium magnesium phosphate,furthermore,the effect of phosphates on the products was increasing with the increase of phosphate-applying.It was viewed that single super phosphate(P2O5 60～75 kg/hm2)applied in calcareous rice field in prematurity rice was efficiency measure of yield-increasing. |
