摘要:

为提高肥料利用率,追求水稻增产效益,本试验以籼粳杂交水稻品种‘甬优12’为材料,探究不同类型缓释肥对‘甬优12’产量以及群体结构的影响。结果表明:汉枫缓释肥对‘甬优12’有明显增产效应,较配方肥增产2.7%~3.5%;六国网缓释肥和丰筑缓释肥无明显增产效应。汉枫缓释肥处理下的水稻成穗率和每穗粒数均高于其他处理,弥补了有效穗数较低的不足。各生育期内的叶面积指数和干物质量均以汉枫缓释肥处理最高。综合产量以及群体特征的表现,汉枫缓释肥的经济效益优于六国网缓释肥和丰筑缓释肥,可为‘甬优12’的因种施肥提供依据。

Abstract:

To improve the fertilizer utilization rate and increase the rice yield, the experiment investigated the effect of different types of slow release fertilizers on hybrid rice ‘Yongyou 12’. The results showed that ‘Hanfeng’ slow release fertilizer had a significant effect on yield increase, which was 2.7%-3.5% higher than that of the formula fertilizer. ‘Liuguowang’ slow release fertilizer and ‘Fengzhu’ slow release fertilizer had no significant yield increase effect. The spike rate and the number of grains per spike under ‘Hanfeng’ slow release fertilizer were higher than that of others, which compensated the lower effective spike number. The leaf area index and dry matter under ‘Hanfeng’ slow release fertilizer were the highest in growth. Based on the performance of yield and population characteristics, ‘Hanfeng’ slow release fertilizer was better than that of ‘Liuguowang’ and ‘Fengzhu’. It could provide a basis for seed-specific fertilization of ‘Yongyou 12’.
