Abstract: The present invention relates to a method for preparing a humic acid-containing synergistic carrier for accelerating urea conversion. The preparation method includes steps of, for example, preparing an extractant for humic acid, preparing a humic acid extract and preparing a humic acid-containing synergistic carrier. Combination of the humic acid-containing synergistic carrier with urea can accelerate urea conversion, and the residual urea rate will be reduced by 22.7%-29.1% than a commercially available urea. The present invention provides a new idea for improving the utilization rate of nitrogen fertilizer in soil with low urease activity. Compared with a commercially available urea, the urea containing the humic acid-containing synergistic carrier of the present invention can increase the rice yield and the utilization rate of nitrogen fertilizer by 9.7% and 8.3%, respectively.

Abstract: The present invention relates to an organic nutrient-based dissolution accelerator for potassium sulfate and a preparation method therefor and the use thereof. The organic nutrient-based dissolution accelerator for potassium sulfate of the present invention consists of an organic acid mixture solution, tyrosine, leucine, threonine, alcohol amine, and the like. The organic nutrient-based dissolution accelerator for potassium sulfate of the present invention can not only substantially improve the dissolution speed of potassium sulfate by 6-120 times, but also provides organic nutrition for crops to achieve a synergy with inorganic nutrition to further improve the nutritional efficiency of potassium and sulfur elements.

Abstract: A sample transport method, applied to a test instrument including a conveyor belt, and a loading platform and a grab position sequentially disposed along a transport direction of the conveyor belt, wherein a plurality of sample holder transport positions are disposed on the conveyor belt; the method including: pushing a first sample holder from the loading platform to a sample holder transport position of the conveyor; when a sample position on the first sample holder moves to the grab position, determining whether the sample position moved the grab position is a target sample position; if so, then determining whether all samples positions on the first sample holder before the target sample holder other than a predetermined number of sample positions have completed testing, wherein the predetermined number is sample position number corresponding to a delay time in outputting information indicating whether a sample needs to be retested.
