滴灌条件下复合微生物菌肥替代部分氮肥对制种玉米产量及品质的影响
Effect of Partial Nitrogen Fertilizer Replacement by Compound Microbial Fertilizer on Yield and Quality of Seed-Producing Maize under Drip Irrigation
摘要
Abstract
[Objective]To explore the effects of replacing 40%nitrogen fertilizer with compound microbial fertilizer on the growth,yield,and seed quality of female parent of drip-irrigated seed-producing maize.[Method]Using the maize seed-producing combination'Leidan No.1'as the test material,three treatments were set up:no fertilization(CK),conventional fertilization(CG),and replacement of 40%nitrogen fertilizer with compound microbial fertilizer(JF).Through field experiments,growth indicators such as plant height,leaf area,and biomass of maize in different growth periods,as well as yield,1 000-grain weight,and germination potential of F1 seeds were investigated.[Result]In terms of growth indicators,JF performed prominently in the vegetative growth stage.At the large bell-mouth stage,the plant height and stem diameter of JF increased significantly by 18.08%and 24.95%respectively compared with CG.After entering the silking stage and maturity stage,there were no significant differences in plant height,leaf area,stem diameter and other indicators between JF and CG.The accumulation of biomass(leaves,stems,ears,and total biomass)of JF in each period was not significantly different from that of CG,but both were higher than those of CK.In terms of yield and its components,there were no significant differences in yield,ear diameter,number of rows per ear,number of grains per row,etc.between JF and CG;however,the number of grains per row of JF was significantly increased by 24.59%compared with CK.In terms of seed quality,the germination rates of JF and CG were both 100%,which were significantly higher than that of CK.There were no significant differences in average seed diameter,1000-grain weight,germination rate,germination potential,and germination index between JF and CG,but both were better than those of CK.[Conclusion]Although the replacement of 40%nitrogen fertilizer with compound microbial fertilizer had obvious advantages in the vegetative growth stage,there were no significant differences in yield,biomass at maturity,and core seed quality indicators compared with conventional fertilization.Therefore,reducing nitrogen fertilizer input while rationally applying microbial fertilizer can ensure the stable yield of maize seed production and improve seed quality.关键词
