为了探明土壤调理剂对酸化稻田土壤理化性状及连作晚稻产量的影响效应，挖掘甬优538高产潜力，设置了土壤调理剂32%氨基质钙镁肥不同用量试验。结果表明，施用土壤调理剂对甬优538有明显增产效应，其中每hm2施600 kg、900 kg、1125 kg的处理比未施用对照增产8.31%~9.52%，达显著水平；其增产效应主要在于增加有效穗数和提高千粒重；施用土壤调理剂还能有效改善酸化稻田土壤理化性状，促进碱解氮、有效磷及速效钾的释放利用和有机质提升。通过一系列数学关系模型分析后发现，在生产上土壤调理剂施用量以600~900 kg/hm2为宜。
為瞭探明土壤調理劑對痠化稻田土壤理化性狀及連作晚稻產量的影響效應，挖掘甬優538高產潛力，設置瞭土壤調理劑32%氨基質鈣鎂肥不同用量試驗。結果錶明，施用土壤調理劑對甬優538有明顯增產效應，其中每hm2施600 kg、900 kg、1125 kg的處理比未施用對照增產8.31%~9.52%，達顯著水平；其增產效應主要在于增加有效穗數和提高韆粒重；施用土壤調理劑還能有效改善痠化稻田土壤理化性狀，促進堿解氮、有效燐及速效鉀的釋放利用和有機質提升。通過一繫列數學關繫模型分析後髮現，在生產上土壤調理劑施用量以600~900 kg/hm2為宜。

In order to find out the effects of soil conditioner on soil physical-chemical properties and the yield of continuous cropping late rice, exploit high yield potential of Yongyou 538, the 32%soil conditioner application amount experiment was carried out. The re-sults showed that the yield of Yongyou 538 was accelerated with the increase of soil conditioner application, about 8.31% to 9.52%. The soil conditioners not only improved the chemical and physical properties of acid soil, increased the soil available organic, nitro-gen, phosphous and ptotassium, but also increased the effective panicles and 1 000-grain weight. The suitable amount of acid soil conditioner is 600~900 kg/hm2.
