Deep Stamping Products, it can also be called Deep Metal Stamping Parts,Deep Processing Metal Stamping Parts,Deep Processing Stamping Parts.
The manufacturing process of stamping parts is stamping processing. Stamping processing is a kind of power by means of conventional or special stamping equipment, so that the sheet is directly subjected to deformation force and deformed in the mold, so as to obtain product parts of certain shape, size and performance. production technology. Sheet metal, mold and equipment are the three elements of stamping processing.

Soil testing and formula fertilization is based on fertilizer field tests and soil tests. Based on the law of fertilizer requirements for crops, soil nutrient supply performance, and fertilizer effects, based on the rational application of organic fertilizers, nitrogen, phosphorus, potassium, and trace elements are proposed. Fertilizer application variety, quantity, fertilization period and application method.
2. Formula fertilizer
Based on the soil test and fertilizer field experiment, based on the laws of crop manure requirements, soil nutrient properties, and fertilizer effects, various kinds of simple fertilizers and/or compound fertilizers are used as raw materials to prepare specific regions and specific crop varieties. Fertilizer.
3, fertilizer effect fertilizer response
Fertilizer effect is the effect of fertilizer on crop yield and quality. It is usually expressed in terms of the increase in crop yield and the benefits obtained by the amount of nutrients per unit of fertilizer.
4, dose rate; dose
The mass or volume of fertilizer or nutrient applied to cultivated land per unit area or per unit mass of growth medium.
5, regular fertilizing
Also known as custom fertilization, refers to the local average fertilization amount (mainly refers to nitrogen, phosphorus, potassium fertilizer), fertilization varieties and fertilization methods in the previous three years.
6, blank control
No fertilizer treatment is used to determine the absolute value of the fertilizer effect, to evaluate the natural soil productivity and to calculate the fertilizer utilization rate.
7, land fertility
It refers to the productivity of cultivated land composed of the characteristics of soil itself, natural background conditions, and farmland infrastructure under the current management level.
8. Cultivated land productivity evaluation
It refers to the comprehensive characteristics of the interactions among the climate, landform, soil parent material, soil physical and chemical properties, farmland infrastructure, and other factors, and is based on the characteristics of the farmland ecological environment, crop planting suitability, and the potential biological productivity of cultivated land. Evaluation.
The construction of evaluation index system for soil and fertilizer station, that is, the software for construction of evaluation index system for soil and fertilizer station, can calculate relative yield and relative absorption, and can perform correlation analysis, significant test and other more functions on soil test methods and relative crop yield.
Stamping is a metal cold deformation processing method. Therefore, it is called cold stamping or sheet metal stamping, or stamping for short. It is one of the main methods of metal plastic processing (or pressure processing), and it also belongs to material forming engineering technology.
