摘要
针对陕西省土地整治后存在的土壤板结、土壤贫瘠、耕性差、产能低等问题,采用果渣发酵黄腐酸为载体的黄腐酸土壤改良剂,依托延安治沟造地土壤整治项目,开展了新增耕地生土快速熟化技术研究。结果表明,应用该技术与改良前相比,速效氮由未检出到检测值25.20~40.24mg·kg^(-1),速效磷含量增幅为30.24%~54.15%,速效钾含量增幅为84.71%~151.76%,有机质均增幅为82.86%~117.14%,玉米产量较对照增加296.0~432.6kg·亩^(-1),增幅为70.5%~103.1%,改良效果显著。
To solve the problems of hard soil,poor soil,poor tillage and low productivity in Shaanxi Province after land consolidation,using fruit residue fermentation fulric acid as the carrier of the fulric acid soil improvers and carrying out new farmland rapid aging technology research,so as to improve quality grade and capacity.The results showed that compared with the application of the technology,the undected available nitrogen before conducting the teconology turned 25.20~40.24 mg·kg^(-1).The available phosphorus content grew 30.24 to 54.15%,the potassium content grew 84.71%~151.76%,organic matter grew 82.86%~117.14%,corn yield increased 296~432.6 kg· mu^(-1),grew 70.5 to 103.1%,and the improvement effect was remarkable.
