摘要
针对传统颗粒肥易结块、肥效低、污染大、能耗高的缺点,设计一种直径较大的球形秸秆复混肥.经过材料成型工艺的研究,确定粉碎-过筛-复混-制坯-烘干的基本工艺流程,然后通过系统性的试验优化原料过筛参数和混料比例.通过玉米一次性施肥的栽培试验,验证新型复混肥的肥效.结果显示,施用该新型秸秆复混肥能够降低玉米的株高、穗位高,增粗茎秆,提高抗倒伏能力,提高玉米的干物质质量、氮素累积量和籽粒氮素分配比率.此外,新型秸秆复混肥具有环保、低碳等优势,可针对不同农作物定制专用肥料,有望推进化肥减量增效.
Abstract
A larger diameter spherical straw compound fertilizer is designed to address the drawbacks of traditional granular fertilizers,such as easy clumping,low fertilizer efficiency,high pollution,and high energy consumption.After studying the material forming process,the basic process flow of crushing-screening-remixing-embryo making-drying is determined,and then the raw material screening parameters and mixing ratio are optimized through systematic experiments.Finally,the cultivation experiment of one-time fertilization of corn is conducted to verify the fertilizer efficiency of the new compound fertilizer.The results show that the application of this new type straw compound fertilizer can reduce the plant height and ear height of corn,thicken the stem,improve lodging resistance,and increase the dry matter mass,nitrogen accumulation,and grain nitrogen distribution rate of corn.In addition,the new type straw compound fertilizer has the advantages of environmental protection and low carbon,it can also customize special fertilizers for different crops,which is expected to promote the reduction and efficiency improvement of chemical fertilizers.
