摘要
以生活炉渣、建筑废料、生物秸秆等城乡废弃资源为原料,制备一种面向节水农业的环保新产品———土壤扩蓄增容肥.实验结果表明：在棉花苗期,6种土壤扩蓄增容肥配方的节水效果较土对照高300倍,干物质积累增加4.77%-50.00%.6种配方的皮棉产量均比对照高,增产幅度为4.70%-14.25%,纤维物理性状有所改善.产量高低顺序依次是,玉米秸秆〉小麦秸秆〉生活炉渣〉秸秆木炭〉建筑废料〉煤矸石〉CK.利用城乡废弃资源生产的扩蓄增容剂,不仅能改良土壤物理和化学性状,更是棉花增产、优质、节水、降低生产成本的关键技术措施之一,具有显著的生态效益、社会效益和经济效益.
A new soil amendment was developed with urban and rural waste resources, such as living slag, construction scrap and crop str w. The experimental results show that., six kinds of soil amendment formula have strong water absorbing capacity, 300 times higher than the contrast, 4.77%-50.00% increase in dry matter accumulation during the cotton seedlings period. Meanwhile the yield of lint was increased by 4. 70% -14.25%; and the physical properties of fiber was improved. The order of cotton yield followed by corn straw〉 wheat straw〉 life slag〉 straw charcoal〉 construction waste〉 coal gangue〉 CK. The soil amendment was developed with urban and rural waste resources will not only improve the soil physical and chemical properties, but also was regarded as one of the key technologies to increase the cotton yield, improve the quality, save water and decrease the cost of production with significant ecological benefits, social efficiency and economic benefits.
