Process research and fertilizer efficiency verification of a new type straw compound fertilizer
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.
