摘　　要：以常农粳12号为试验对象,研究不同种类缓混肥对水稻生长的影响。结果表明:不同种类缓混肥对常农粳12号水稻生长及产量的影响有一定差异,以汉枫缓释肥料有限公司生产的专用缓混肥(30-6-12)效果最好,其能有效提高水稻最高分蘖数,在抽穗前期及成熟期可有效提高剑叶SPAD值,促进植株的光合作用,与江苏艾萨斯新型肥料工程技术有限公司生产的水稻专用缓释肥(33-5-12)及稳定性肥料(26-10-15)相比,理论产量分别提高0.68%和1.43%,实际产量分别提高了9.6%和6.1%。Using Changnongjing 12 as the experimental object,this paper studied the effects of different types of slow mixed fertilizers on rice growth.The results showed that there were certain differences in the effects of different types of slow mixed fertilizers on the growth and yield of Changnongjing 12,among which,the special slow mixed fertilizer(30-6-12)produced by Hanfeng Slow Release Fertilizer Co.,Ltd.had the best effect.It could effectively increase the highest tillering number of rice,effectively increase the SPAD value of flag leaves in the early and mature stages,promote plant photosynthesis,and compared with the rice special slow-release fertilizer(33-5-12)and stable fertilizer(26-10-15)produced by Jiangsu Aisas New Fertilizer Engineering Technology Co.,Ltd.,the theoretical yield increased by 0.68%and 1.43%,and the actual yield increased by 9.6%and 6.1%,respectively.
