    摘要:

    为摸清种植模式对鲁南地区潮土养分变化趋势的影响,2006~2020年在临沂市河东区开展土壤养分调查,统计分析了粮粮轮作、粮经轮作、粮菜轮作、蔬菜连作、果树连作5种种植模式土壤养分的变化趋势。结果显示:2006年蔬菜连作模式土壤有机质、碱解氮、有效磷、速效钾含量最高,粮粮轮作、粮经轮作模式土壤养分含量相对较低;2006~2020年5种种植模式土壤pH值均呈直线下降的趋势,2020年粮经轮作模式土壤pH值为5.29,达到强酸水平;2006~2020年5种种植模式土壤有机质含量呈直线上升的趋势,其中粮粮轮作模式土壤有机质增量和增幅较大,与2006年相比较,2020年粮粮轮作模式土壤有机质含量累计增加了5.9 g/kg,增幅为32.96%;与2006年相比较,2020年粮食轮作、粮经轮作、粮菜轮作、果树连作模式土壤碱解氮、有效磷、速效钾含量均有不同程度的上升,但其变化趋势存在一定差异;2006~2020年蔬菜连作模式土壤碱解氮、有效磷、速效钾含量均呈先下降后又小幅回升的趋势。2020年蔬菜连作模式土壤碱解氮为302.6 mg/kg,较2006年上升了43.3 mg/kg。2020年蔬菜连作模式土壤有效磷和速效钾含量分别为175.6和411.2 mg/kg,分别较2006年下降了36.7和113.7 mg/kg。

    Abstract:

    In order to find out the influence of planting patterns on the change trend of nutrients in fluvo aquic soil in southern Shandong province,soil nutrient survey was carried out in Hedong district of Linyi city from 2006 to 2020,and the change trend of soil nutrients in five planting patterns including grain-grain crops rotation,grain-cash crops rotation,grain-vegetable rotation,vegetable continuous cropping and fruit tree continuous cropping were analyzed. The result indicated that:in 2006,the contents of soil organic matter,alkali hydrolyzable nitrogen,available phosphorus and available potassium were the highest in the vegetable continuous cropping pattern,while the contents of soil nutrients were relatively low in the grain-grain crops rotation and grain-cash crops rotation patterns. From 2006 to 2020,the soil pH values of the five planting patterns showed a linear downward trend. In 2020,the soil pH value of the grain-cash crops rotation pattern was 5.29,reaching the strong acid level. From 2006 to 2020,the content of soil organic matter in five planting patterns showed a straight-line upward trend,and the increment and increase of soil organic matter in grain-grain crops rotation pattern were larger. Compared with 2006,the content of soil organic matter in grain-grain crops rotation pattern increased by 5.9g/kg in 2020,with an increase of 32.96%. Compared with 2006,the soil alkali hydrolyzable nitrogen,available phosphorus and available potassium contents of grain-grain crops rotation,grain-cash crops rotation,grain-vegetable rotation and fruit tree continuous cropping patterns increased significantly in 2020. From 2006 to 2020,the contents of alkali hydrolyzable nitrogen,available phosphorus and available potassium in the soil of continuous vegetable cropping pattern decreased at first and then increased slightly. In 2020,the soil alkali hydrolyzable nitrogen of vegetable continuous cropping pattern was 302.6 mg/kg,which was increased by 43.3 mg/kg,compared with 2006. In 2020,the content of soil available phosphorus and available potassium of grain-vegetable rotation pattern were 175.6 and 411.2 mg/kg,respectively,which decreased by 36.7 and 113.7 mg/kg,compared with 2006.
