| 【目的】为明确减施化肥条件下接种根瘤菌剂对花生产量及经济效益的影响，促进花生产业绿色、高产。【方法】选用高产花生品种泰0605-2为试验材料，田间采用小区试验，设置7个处理，常规施肥(N100%)+根瘤菌菌剂拌种、减氮20%(N80%)+根瘤菌菌剂拌种、减氮40%(N60%)+根瘤菌菌剂拌种、减氮60%(N40%)+根瘤菌菌剂拌种、减氮80%(N20%)+根瘤菌菌剂拌种、减氮100%+根瘤菌菌剂拌种、减氮100%+不用根瘤菌拌种。选择以常规施肥为对照 （CK），研究不同减氮施肥方式下拌种根瘤菌剂处理对花生结瘤数量、生长发育、干物质积累量、产量和经济效益的影响。【结果】在苗期和花针期阶段，常规施肥(N100%)花生根瘤数数量最少，随着施氮量的减少逐渐增加，在结荚期以后，减氮40%(N60%)处理下根瘤数、株高、侧枝长、分枝数、有效枝数和鲜物质量积累量以及产量比对照处理增加。通过经济效益分析可知,在本试验条件下，氮肥用量67.5 kg/hm2+根瘤菌菌剂拌种产量最高为5216.08kg/hm2，净增收效益最显著，产值为36512.55元，较对照常规施肥CK增加收益2526.45元/hm2。【结论】减氮40%接种根瘤菌剂处理能够提高花生株高、侧枝长、分枝和有效枝数等农艺性状，达到稳产增收的效果，比对照荚果产量增产5.30% 。 |

| Abstract: 【Objective】In order to clarify the impact of inoculation of rhizobia agent on peanut yield and economic benefits under the condition of reduced application of chemical fertilizer, and promote the green and high yield of peanut production industry.【Method】The high-yielding peanut variety Taihua 0605-2 was selected as the experimental material, and the field experiment was used to inoculate rhizobia agent by set 7 treatment, conventional fertilization (N100%) + rhizobia agent seed dressing, nitrogen reduction 20% ((N80%) + rhizobia agent seed dressing; Nitrogen reduction 40% ((N60%) + rhizobia agent seed dressing; Nitrogen reduction 60% ((N40%) + rhizobia agent seed dressing; Nitrogen reduction 80% ((N20%) + rhizobia agent seed dressing; Nitrogen reduction 100% + rhizobia agent seed dressing; Nitrogen reduction 100% + no rhizobia seed dressing.and conventional fertilization was selected as the control (CK) to study the effects of rhizobia agent (seed coating) treatment on the number of peanut nodulations, growth and development, dry matter accumulation, yield and economic benefits under different nitrogen reduction fertilization methods. 【Result】The number of nodules in peanut under conventional fertilization (N100%) was the lowest at seedling stage and flowering needle stage, and gradually increased with the decrease of nitrogen application rate, and after the podding stage, the number of nodules, plant height, lateral branch length, branch number, effective branch number, fresh matter mass accumulation and yield increased under 40% nitrogen reduction (N60%) treatment compared with the control treatment. Through the analysis of economic benefits, under the conditions of this experiment, the highest yield of nitrogen fertilizer dosage of 67.5 kg/hm2 + rhizobia agent was 5216.08kg/hm2, and the net income increase was the most significant, with an output value of 36512.55 yuan, which increased the yield by 2526.45 yuan/hm2 compared with the control conventional fertilization CK.【Conclusion】The 40% nitrogen reduction inoculation treatment could improve the agronomic traits of peanut such as plant height, lateral branch length, branch and effective branch number, and achieve the effect of stabilizing yield and increasing income, which was 5.30% higher than that of the control pod. |
