摘要
为了解决宁夏土地沙化问题,提高风沙土土壤质量和土地生产力,通过田间试验研究了BGA土壤调理剂对风沙土土壤理化性质和作物生长发育的影响,评价了BGA土壤调理剂的施用效果。研究结果表明,与不施肥相比,施用BGA土壤调理剂改善了风沙土土壤理化性质,促进了酿酒葡萄、樱桃番茄和甘草的生长发育,显著提高了酿酒葡萄和樱桃番茄的产量,改善了酿酒葡萄和甘草品质;与配方施肥相比,施用BGA土壤调理剂改善了风沙土土壤理化性质,促进了酿酒葡萄和樱桃番茄的生长发育,显著降低了甘草产量,改善了酿酒葡萄品质。施用BGA土壤调理剂大幅度增加了生产投入成本,建议进一步降低BGA土壤调理剂的生产成本或与化肥配合施用。
In order to solve the problem of land desertification in Ningxia,improve aeolian sandy soil quality and increase land productivity,the application effect of BGA soil conditioner on aeolian sandy soil and crops was studied and evaluated through field plot experiment.The results showed that,compared with no fertilizer,BGA soil conditioner improved physical and chemical properties of aeolian sandy soil,promoted the growth of wine grape,cherry tomato and liquorice,increased significantly the yield of wine grape and cherry tomato,improved the quality of wine grape and liquorice.Compared with balanced fertilization,BGA soil conditioner improved physical and chemical properties of aeolian sandy soil,promoted the growth of wine grape and cherry tomato,decreased significantly the yield of liquorice,improved the quality of wine grape.The application of BGA soil conditioner greatly increased the investment cost of production.It was proposed to reduce production cost of BGA soil conditioner and combine application of BGA soil conditioner with chemical fertilizers.
