摘要
为了解决宁夏引黄灌区土壤盐碱障碍问题,提高盐碱障碍型土壤质量,增强土地生产力,通过田间试验,研究了BGA土壤调理剂对盐碱障碍型土壤理化性质及作物生长发育的影响,评价了BGA土壤调理剂的施用效果。结果表明:与不施肥相比,施用BGA土壤调理剂改善了盐碱障碍型土壤理化性质,促进了油葵、水稻及枸杞的生长发育,显著提高了3种作物产量,改善了油葵、水稻的品质;与配方施肥相比,施用BGA土壤调理剂改善了盐碱障碍型土壤理化性质,促进了油葵、水稻的生长发育,显著提高了3种作物产量,改善了油葵的品质。如果能够有效降低BGA土壤调理剂生产成本并配合化肥合理施用,BGA土壤调理剂改良盐碱障碍型土壤是可行的,值得进一步研究应用。
In order to solve the problem of soil saline-alkaline obstacle in Yellow River irrigation area of Ningxia, improve saline-alkaline obstacle soil quality, and increase land productivity, the application effect of BGA soil conditioner on saline-alkaline soil and crops was studied and evaluated through field plot experiment. The results showed that, compared with no fertilizer BGA soil conditioner improved the physical and chemical properties of saline-alkaline obstacle soil, promoted the growth of oil sunflower, rice and Chinese wolfberry, increased significantly the yield of three crops, improved the quality of oil sunflower and rice. Compared with balanced fertilization BGA soil conditioner improved the physical and chemical properties of saline-alkaline obstacle soil, promoted the growth of oil sunflower and rice, increased significantly the yield of three crops, improved the quality of oil sunflower, It was feasible to apply BGA soil conditioner to improve saline-alkaline obstacle soil if the production cost of BGA soll conditioner could be reduced effectively and BGA soil conditioner could be combined with chemical fertilizers, and it was valuable to further research and develop BGA soil conditioner.
