摘要 采用田间小区试验方法,以正红6号玉米为供试材料,在四川省资阳市临江镇石灰性紫色土上,研究了大型养猪场猪粪尿厌氧发酵的沼液对四川山丘区玉米产量及品质的影响。结果表明,沼液用量5000-7000kg·667m^-2时,玉米产量较高,品质较好;当沼液用量3000-7000kg·667m^-2时,玉米籽粒中Fe、Mn、Zn、Cu、Ca、Mg含量均较高。综合考虑玉米产量和品质,沼液用量以5000-7000 kg·667m^-2为宜。 In order to study the application of biogas slurry of pig manure from a large-scale pig farm on yield and quality of Maize. We conduct a field experiment in Linjiang town,Ziyang City,Sichuan Province. And Zhenghong No. 6 maize were used as the test materials,the soil type is calcareous purple soil. The results indicated that the yield and nutritional quality of maize reached to a relatively high level when the application dosage of the biogas slurry was in the range of 5, 000kg·667m- 2to 7,000kg ·667m- 2. The contents of the Fe,Mn,Cu,Zn,Ca and Mg in maize kernel were all relatively high when the application dosage of the biogas slurry was in the range of 3,000kg·667m^- 2to 7,000kg· 667m^- 2. Considering the effects of the biogas slurry on the yield and quality of maize,the appropriate application dosage of biogas slurry for corn planting shuold be in the range of 5,000 kg·0. 667m^- 2to 7,000 kg·667m^- 2.
