How do you see the nutrition of plants? Is it true that many people judge by observing the growth of plants? In fact, the most obvious manifestation of plant nutrition is its internal changes, it can also be said to be physiological changes, to more accurately and timely understand the nutrient status of plants, it is recommended that you use a professional plant nutrient speed meter for measurement, the instrument can Determination of chlorophyll, nitrogen content, leaf surface temperature, and leaf surface humidity are ideal instruments for plant nutrient management and data analysis.

Modern agricultural development pursues refinement and automation, and to achieve refined management, big data analysis is very important. In the aspect of plant nutrition diagnosis, although it is also possible to determine whether the plant is nitrogen-deficient, potassium-deficient or phosphorus-deficient by the leaves and heights of the plant growth process, this method is not precise and it is difficult to adapt to the development of large-scale agricultural planting industry. Therefore, it is necessary to adopt a more scientific and accurate measurement scheme, and the plant nutrient rapid tester is a specialized instrument dedicated to the determination and analysis of plant nutrients. It can improve the measurement by using instruments in carrying out related plant research and guiding precise fertilization. Efficiency and measurement accuracy, streamline the process, and obtain accurate measurement data to provide big data support for modern agricultural development.

Studies have shown that plant nutrient requirements are not average, not that the highest nutrients affect yield, but that the relatively least nutrient content limits crop yields. Therefore, agricultural fertilization should pursue equilibrium, rather than simply paying attention to the application of nitrogen fertilizer as before. In addition, Zi Yan: too late. Fertilizer is not the more the better, the fertilizer is more expensive, it may also cause fertilizer damage, affecting the output, and even the harvest. Therefore, fertilization should also pursue precision. The application of plant nutrient rapid measuring instrument can not only quickly guide the plant nutrient profit and loss, but also can quickly calculate the standard fertilizer application amount, guide the agricultural science fertilization, ensure the plant nutrition is balanced, and obtain a good harvest.

CNC Turning

CNC Turning is namely Lathe machining, Lathe machining is a portion of mechanical processing.

Lathe machining is always a process that turning tools doing turning machining to a rotary workpiece. On CNC lathes, the operators or the engineers also can use drills, reamers, screw taps, threading dies and knurling tools to make relative machining work. CNC turning is usually applied to machining shafts, plates, bushings and all other workpieces which have rotary surfaces, it is a very widely application in practical mechanical manufacturing.

CNC turning can be divided into rough turning and finish turning, rough turning is for the purpose of machining with big cutting depth and big feed rate, to improve the machining efficiency. However, the precision of rough turning can only be grade IT11, the surface finish can only be Ra 20-10um. On the contrary, semi-finish machining and finish machining usually can only apply high speed but small feeding rate and cutting depth. In this condition, the machining accuracy can be up to grade IT10-7, the roughness can be Ra10-0.6um.
