为满足提高作物产量、品质和肥料利用率、减轻农业面源污染、提升耕地质量、促进农作物高产优质等方面的要求,分析了6种不同种类肥料对水稻产量和品质的影响,以期筛选更适宜巢湖流域水稻生长的肥料品种,从而形成大面积应用模式.采用完全随机区组设计,设置不同肥料品种,不施肥处理(CK)、常规施肥(CF)、控失肥(T1)、缓释掺混肥(T2)、水稻专用肥(T3)和腐植酸复合肥(T4),6种施肥处理进行田间小区试验.于成熟期分析水稻产量、品质以及氮肥利用率.与CF相比,新型肥料在水稻的产量和品质方面均有所提高,T1水稻产量最高为10453.95 kg·hm-2,腐植酸复合肥处理较CK和CF产量分别增加16.4%和13.3%.控失肥处理的氮肥利用率最高,达到48.57%.在水稻品质方面,CK总体食味品质显著低于其他处理,蛋白质含量最高的处理为T4.控失肥和腐植酸复合肥可以显著提高水稻产量和品质,其中腐植酸复合肥价格低有利于节约成本,提高经济效益.
Evaluation of agronomic effects of different new types of special fertilizers for rice
This study aims to enhance crop yield and quality,optimize fertilizer utilization,mitigate non-point source pollution in agriculture,elevate the quality of cultivated land,and promote high yield and high-quality culti-vation of crops.The research investigated the effects of six different types of fertilizers on rice yield and quality in order to identify the most suitable fertilizer varieties for rice cultivation in the Chaohu Lake Basin,so as to form a large-area application model.Different fertilizer varieties were set up by completely random block design,and six fertilizer treatments were tested in the field with no fertilization (CK),conventional fertilization (CF),controlled loss fertilizer (T1),slow controlled release fertilizer (T2),rice special fertilizer (T3) and humic acid compound fertilizer (T4).The rice yield,quality and nitrogen fertilizer utilization were analyzed at maturity.The results indicated that compared to the CF,the yield and quality of rice were significantly improved,the yield of T1 rice was 10453.95 kg·hm-2,while the yield of humic acid compound fertilizer increased by 16.4% and 13.3% compared with CK and CF,respectively.The nitrogen fertilizer utilization rate of controlled fertilizer was the highest,reaching 48.57%.In terms of rice quality,the overall taste quality of CK was significantly lower than that of other treatments,and the treatment with the highest protein content was in T4.Synergistic control of loss and humic acid compound fertilizer can significantly improve rice yield and quality,among which the low price of humic acid compound fertilizer is conducive to saving costs and improving economic benefits.
