| 摘 要： | 目的 研究不同量黄腐酸配施微生物菌肥对玉米生长的影响,筛选出最佳用量,为黄腐酸微生物菌肥替代部分化肥提供理论依据。方法 在温室中进行盆栽试验,采取单因素随机区组试验,共设6个施肥处理,测定玉米株高、茎粗、叶绿素值(SPAD)、干物质量、养分积累、苗期光合特征,分析不同用量黄腐酸微生物菌肥对玉米生长的影响。结果 黄腐酸施用量为150~225 kg/hm 2配施15 kg/hm 2微生物菌肥,玉米农艺性状表现最优,当黄腐酸施用量为225 kg/hm 2,植株干物质量和氮磷钾积累量达最大值,干物质量较CK增加28.81 g/株,增幅138.9%,地上部分氮磷钾积累量分别较CK增加138.9%、276.2%和117.8%。FA150处理和FA225处理苗期Pn、Tr、Gs值均高于其他处理。 结论 黄腐酸+微生物菌肥(150 kg/hm 2+15 kg/hm 2)和黄腐酸+微生物菌肥(225 kg/hm 2+15 kg/hm 2)处理可以有效促进玉米生长,养分积累,增强苗期光合作用,最佳施用量为黄腐酸150~225 kg/hm 2配施15 kg/hm 2微生物菌肥。

| Abstract: | 【Objective】 This project aims to perform pot experiments in greenhouses with the view of exploring the effects of different quantity of fulvic acid combined application with microbial fertilizer on the growth of corn and selecting the best quantity, thus providing theoretical basis for replacing part of chemical fertilizer with microbial fertilizer of fulvic acid microbial fertilizer. 【Methods】 A single-factor randomized block test was adopted, and a total of 6 fertilization treatments were set up. By measuring the plant height, stem thickness, chlorophyll value (SPAD), dry matter quality, nutrient accumulation, and photosynthetic characteristics of seedlings, the effects of different quantity of fulvic acid microbial fertilizer on the corn growth was analyzed. 【Results】 The application quantity of fulvic acid was 150-225 kg/hm 2 combined with the application of 15 kg/hm 2 microbial fertilizer, the agronomic performance of corn was the best. When the application quantity of fulvic acid was 225 kg/hm 2, the plant dry matter quantity and the accumulation of N, P, K reached the maximum value, the dry matter quantity increased by 28.81 g/plant compared with CK, an increase of 138.9%, and the accumulation of N,P,K in the aboveground increased by 138.9%, 276.2%, and 117.8% compared with CK. PN, TR, GS of FA150 treatment and FA225 seedling stage treatment were higher than those of other treatments. 【Conclusion】 The comprehensive analyses demonstrate that FA150 and FA225 treatment can promote the growth, nutrient accumulation and photosynthesis of corn seedlings. The best application quantity of fulvic acid is 150-225 kg / hm 2 combined application with 15 kg / hm 2 microbial fertilizer. |
