发展生物硫肥料在科威特的沙漠土壤肥力的提高

文摘

目的:科威特沙漠土壤的碱性性质导致植物萌发的打扰,吸收的水和肥料在增长,导致一个环境,植物无法生长。当地土壤碱性pH值一般在9.00以上。这对许多植物太高。利用新开发的单质硫和sulfur-oxidizing细菌生物肥料,它是假设土壤酸化足以改善土壤性质,从而增加营养的程度可用性和农作物产量。方法:在房子sulfur-oxidizing微生物筛选、富集和分离在科威特。最具潜力的菌株通过生长和养分优化修改。生物肥料颗粒的生产过程利用副产品硫和sulfur-oxidizing微生物的培养液。土壤颗粒作为增强剂的有效性进行了测试与紫花苜蓿植物在温室和田间条件下。结果:总体而言,增加应用程序的硫、铅显著降低pH值和紫花苜蓿干物质生产在温室条件下增加。应用率最高的20 g S公斤造成两个单位减少生长介质的pH值在45天内。 On the other hand, the field evaluation for the biofertilizer produced has slightly reduced soil pH compared to the greenhouse pH reduction. Conclusion: The use of the biological sulfur fertilizer has produced positive responses in terms of changing pH of the growth medium in greenhouse and field test as well as the growth responses by the test crop used in this investigation.
