为明确水稻侧深施肥专用缓释肥一次性施用相对于常规施肥的优势,以及不同水稻侧深施肥专用缓释肥对水稻农艺性状及产量的影响,在5个农场开展了示范试验,在8个农场对4种水稻侧深施肥专用缓释肥开展了对比试验。示范试验结果表明:与常规施肥处理相比,水稻侧深施肥专用缓释肥一次性施用处理的产量平均提高4.5%。对比试验结果表明:红四方水稻侧深施肥专用缓释肥处理的齐穗期每穴株数多,千粒质量、结实率和产量高,具有较好的增产效果;红四方水稻侧深施肥专用缓释肥处理的施肥成本低,效益高。
In order to clarify the advantages of one-time application of specialized slow release fertilizers for side deep fertilization of rice compared to conventional fertilization, and the effects of different specialized slow release fertilizers for side deep fertilization of rice on agronomic traits and yield, demonstration experiments are conducted in 5 farms, and comparative experiments are conducted on 4 types of specialized slow release fertilizers for side deep fertilization of rice in 8 farms. The results of the demonstration experiments show that compared with conventional fertilization treatment, the yield of rice treated with one-time application of specialized slow release fertilizer for side deep fertilization increased by an average of 4.5%. The comparative test results show that the treatment of side deep fertilization with Hongsifang specialized slow release fertilizer of rice has a higher number of plants per hole during the full heading stage, higher thousand grain weight, seed setting rate, and yield as well as a better yield increasing effect. The application of Hongsifang specialized slow release fertilizer for side deep fertilization of rice has low fertilization costs and high benefits.
