摘要:
采用完全随机区组设计,在等量养分供应条件下,以单施化肥(NPK)为对照,研究基施猪粪有机肥替代化肥的10%(M10)、20%(M20)、30%(M30)、40%(M40)四个比例对玉米不同生育期土壤养分变化及土壤酶活性的影响,为山原红壤化肥减施、有机培肥和作物增产提供科学依据。结果表明:随基施有机肥替代比例的增加土壤养分呈增加趋势,与NPK处理相比,M10处理土壤养分含量无显著变化;M20、M30、M40处理玉米拔节期至抽雄期土壤养分含量显著增加,成熟期土壤有机质、全氮、速效磷、速效钾含量增幅分别高达7.10%-8.46%、24.18%-26.37%、13.00%-18.31%、12.43%-17.43%(P<0.05);与基肥处理前相比,M40处理土壤有机质、全氮、碱解氮、速效磷、速效钾含量分别增加了2.64 g/kg、0.31 g/kg、15.36 mg/kg、3.96 mg/kg、16.09 g/kg。基施有机肥玉米生育期土壤转化酶、脲酶、磷酸酶总体上先增后降,转化酶、磷酸酶活性相对高峰为抽雄期,脲酶活性相对高峰为大喇叭口期,过氧化氢酶呈逐渐升高趋势;M40处理土壤转化酶、磷酸酶活性较高,由25.24 mg/kg、0.262 mg/kg分别增加到31.53 mg/kg、0.328 mg/kg,成熟期较NPK处理分别提高了80.54%、77.29%;而土壤脲酶、过氧化氢酶活性M30处理最高,成熟期较NPK处理分别增加了11.25 mg/kg、1.28 ml/g。同时,M30、M40处理较NPK处理相比,玉米籽粒产量由6808.38 kg/hm2提高到7860.58 kg/hm2和7463.66 kg/hm2,分别显著提高了15.45%、9.62%(P<0.05),且M30、M40差异不显著。多因素方差分析显示基肥处理和生育时期对有机质、全氮、有效磷、转化酶和磷酸酶有极显著的交互作用,而玉米产量与土壤养分和酶活性之间总体上呈显著或极显著正相关。本研究表明在山原红壤上进行基施有机肥替代化肥,短期内能改善与土壤碳、氮、磷循环密切相关的土壤酶活性,培肥土壤,提高作物产量,替代范围在30%-40%作用效果较好。(图4 表3 参38)
Abstract:
The aim of this research was to provide a scientific basis of reduced fertilizer, increased yield and reclaimed soil biochemical fertility of the mountain red earth. Through the pot experiment completely randomized design was used to investigate the effects of pig manure replacing chemical fertilizer 10% (M10), 20% (M20), 30% (M30), 40% (M40) four replacement ratios in equal nutrient supply conditions on changes of the soil nutrients and soil enzyme activity in different growth stages of maize. The results showed that compared with NPK treatment, there was no significant difference in soil nutrient change during the four growth stages of M10 treatment, and the soil nutrient content of M20, M30 and M40 treatments increased significantly from the tasseling stage to the mature stage, soil organic matter, total nitrogen, available phosphorus and available potassium increased by 7.10%. 8.46%, 24.18% -26.37%, 13.00%-18.31%, 12.43%-17.43% (P<0.05) in the mature stage, respectively, with the increase of the proportion of organic fertilizer replacement, the soil nutrients were increased, and the contents of organic matter, total nitrogen, alkaline nitrogen, available phosphorus, and available potassium in M40 treated soil increased by 2.64 g/kg, 0.31 g/kg, 15.36 mg/kg, 3.96 mg/kg, 16.09 g/kg compared with the treatment before basal fertilizer, respectively. Activities of soil invertase, urease and phosphatase in different treatments all increased initially and then decreased, with relatively higher of invertase and phosphatase activity in the tasseling stage and urease activity in the trumpet stage. Soil catalase activities increased gradually during the maize growing season. The treatment of M40 soil invertase, phosphatase activity was the highest, which increased from 25.24 mg/kg and 0.262 mg/kg to 31.53 mg/kg and 0.328 mg/kg, respectively, and increased by 80.54%, 77.29% compared with the treatment of NPK in the mature stage. The treatment of M30 soil urease and catalase activity was the highest, increased by 11.25 mg/kg and 1.28 ml/g compared with the treatment of NPK in the mature stage, respectively. Simultaneously, M30 and M40 treatments were significantly increased by 15.45% and 9.62% Compared with NPK treatment, respectively (P<0.05), the yield of maize from 6808.38 kg/hm2 to 7786.58 kg/hm 2 and 7463.66 kg/hm 2, and have no significant difference between M30 and M40. Multivariate analysis of variance showed significant interaction between organic matter, total nitrogen, available phosphorus, invertase and phosphatase during base fertilizer treatment and growth period, but generally significant or very significant positive correlation between maize yield and soil nutrients, soil enzyme activities. Therefore, Organic manure replacing fertilizer helps to promote the overall ascension of soil quality, crop production, and enzyme activity of soil, which improves the contribution of C, N, P recycling of the mountain red earth.
