| 为研究土壤调理剂对高标准农田制种玉米产量及土壤养分的影响，研究通过对玉米增施亲土1号、农科2号和矿源黄腐酸钾等5种土壤调理剂，测定其对玉米农艺性状、土壤养分、玉米产量等指标的影响，初步筛选出适宜该生产区施用的土壤调理剂。结果表明,亲土1号和如金处理的土壤,玉米产量表现较优，较CK分别增产5.8%和5.3%，5种调理剂均能增加玉米茎粗、叶片厚度、叶绿素含量和氮含量，以亲土1号处理的促进作用较强，亲土1号、施地佳、农科2号处理的土壤容重分别降低了4.1%、2.7%和0.7%，5种调理剂pH值均有不同程度的变化。亲土1号处理的土壤有机质、碱解氮、有效磷和速效钾含量分别较CK高3.8%、8.4%、12.9%、17.9%。 |

| To study the effects of soil conditioners on the yield of maize for seed production in high-standard farmland and soil nutrients, five soil conditioners, including Qiantu No. 1, Nongke No. 2, and mineral-source potassium fulvic acid, were applied to maize at increased doses. The effects of these conditioners on maize agronomic traits, soil nutrients, and maize yield were measured to preliminarily screen suitable soil conditioners for use in the production area. The results showed that Qiantu No. 1 and Rujin treatments had higher yield performance, with increases of 5.8% and 5.3% compared with CK, respectively. All five conditioners increased stem thickness, leaf thickness, chlorophyll content, and nitrogen content of maize, with the Qiantu No. 1 treatment showing a stronger effect. Qiantu No. 1, Shidijia, and Nongke No. 2 treatments reduced soil bulk density by 4.1%, 2.7%, and 0.7%, respectively, and pH varied to varying degrees among the five conditioners. The contents of organic matter, alkali-hydrolyzable nitrogen, available phosphorus, and available potassium in the Qiantu No. 1 treatment were higher than those in CK by 3.8%, 8.4%, 12.9%, and 17.9%, respectively. |
