摘　　要：本文对控释掺混肥在水稻的应用上进行了研究。与普通肥相比，水稻控释掺混肥不同养分配比、不同肥量处理增加了水稻秸秆氮、磷、钾含量分别为10％～23％、7．7％～11．7％、5．5％～26．6％；控释掺混肥能提高水稻亩穗数、穗粒数、千粒重和产量，水稻籽粒增产率14．1％～16．7％，差异显著；不同控释掺混肥处理显著提高了氮肥利用率，达42．84％～90．48％；不同处理水稻收获时叶绿素、株高、籽粒淀粉含量差异不显著。This paper studied application of controlled - release compound fertilizer on paddy rice. Controlled - release compound fertilizer with different nutrient proportion and different fertilization weight increased Nitrogen - phosphorus - potassium content of paddy rice to 10 - 23% ,7.7% - 11.7% ,5.5% - 26.6% as compared to common fertilizer. Controlled-release compound fertilizer could also enhance paddy rice spike number, grain number per spike, grain weight per kilo and yield. Paddy rice seed yield increased Singnificantly to 14.1% - 16.7%. Different treatments could enhance fertilizer utilization Singnificantly to 42.84% - 90.48%. Lamina chlorophyll, plant height, seed amylum content of different treatments in the period of harvest has inapparent difference.
