摘　　要：在江汉平原稻虾共作区,通过田间小区试验研究3种新型肥料对直播水稻产量及养分吸收的影响。结果表明,对于新型包膜氮钾复合肥,在一次性施肥条件下,随包膜肥所占比例的下降,水稻的产量表现出下降趋势,所有包膜肥处理相对于推荐施肥对照均未表现出明显增产效果,且在水稻生长中后期表现出缺氮症状;对于沃农生物有机肥,在化肥氮减少2.5%~6.3%、化肥钾减少35.4%~72.9%的条件下,相对于推荐施肥处理水稻增产2.1%~3.5%,且增产主要是通过增加有效穗来实现的;对于PPF菌肥,对水稻产量影响不明显。In the integrated rice-crayfish model of Jianghan Plain,the effects of three new fertilizers on the yield and nutrient uptake of direct-seeded rice were studied through field plot experiments.The results showed that under the condition of one-time fertilization,the yield of rice showed a downward trend with the decrease of the proportion of coated fertilizer.All coated fertilizer treatments showed no significant yield effect compared with the recommended fertilization control,and showed the symptoms of nitrogen deficiency in the middle and late stages of rice growth.For fertile agricultural bio-organic fertilizer,the nitrogen decreased by 2.5%~6.3%.Under the condition of reducing potassium fertilizer by 35.4%~72.9%,the yield of rice increased by 2.1%~3.5%compared with the recommended fertilization treatment,and the increase was mainly achieved by increasing effective panicles;For PPF bacterial fertilizer,the effect on rice yield was not obvious.
