不同品种肥料对水稻产量和经济效益的影响

[目的]探究不同品种肥料对水稻产量和经济效益的影响。[方法]以H优7601为参试品种,以湖南金叶众望科技股份有限公司提供的肥料为参试材料,研究不同肥料对水稻生育期、农艺性状、产量以及经济效益的影响。[结果]研究结果表明,使用“众望”牌肥料能明显改善水稻农艺性状,延长生育期增加水稻产量。在水稻产量方面,以掺混肥效果最佳,达7720.8kg/hm2,其次是有机无机复混肥,达7498.80kg/hm2,复合肥处理下的产量相对较低为7459.20kg/hm2,比CK增产25.2%-29.%;经济效益方面,比常规施肥相比,净增加值最大为掺混肥,达1607.37元/hm2,其次是复合肥,达到1237.14元/hm2,常规处理下的增加值最低为46.29元/hm2。[结论]“众望”牌不同品种肥料在水稻上应用能显著提高水稻产质量,不同品种肥效表现为掺混肥>有机无机复混肥>复合肥>常规施肥>CK。

Effects of Different Fertilizers on Rice Yield and Economic Benefits

[Objective] To explore the effects of different types of fertilizers on rice yield and economic benefits. [Method] Using H You 7601 as the experimental variety and fertilizers provided by Hunan Jinye Zhongwang? Science and Technology Co., Ltd. as the experimental materials, the effects of different fertilizers on the growth period, agronomic traits, yield, and economic benefits of rice were studied. [Result] The research results indicate that using the "Zhongwang" brand fertilizer can significantly improve the agronomic traits of rice, prolong the growth period, and increase rice yield. In terms of rice yield, mixed fertilizer has the best effect, reaching 7720.8kg/hm2, followed by organic inorganic compound fertilizer, reaching 7498.80kg/hm2. The yield under the treatment of compound fertilizer is relatively low, at 7459.20kg/hm2, which is 25.2% -29% higher than CK; In terms of economic benefits, compared to conventional fertilization, the maximum net added value is mixed fertilizer, reaching 1607.37yuan/hm2, followed by compound fertilizer, reaching 1237.14yuan/hm2. The minimum added value under conventional treatment is 46.29yuan/hm2. [Conclusion] The application of "Zhongwang" brand fertilizers of different varieties in rice can significantly improve the yield and quality of rice. The fertilizer efficiency of different varieties is manifested as mixed fertilizer>organic inorganic compound fertilizer>composite fertilizer>conventional fertilization>CK.
