Some farmers in the Yimian District of the northern mainland are still entangled with the current cotton prices, their future trends and whether they will plant cotton next year. The author believes that the following three points can help you make the correct analysis. Disclaimer: Some articles on this website are transferred from the Internet.

Roughness profiler all-in-one machine is an all-in-one machine for measuring profile shape and surface roughness, which has the powerful function of analyzing and measuring profile shape and surface roughness. Realize accurate measurement of dimensions, shape and roughness. It is mainly used to measure the parameters of the surface micro-geometry and macro-geometry of mechanical parts such as straightness, inclination, angle treatment, roundness treatment, double-groove treatment, double-arc treatment, etc.

1. The cotton that can be planted in Yimian District of the northern mainland is calculated based on this year's cotton prices. A rural left-behind labor force does not need to hire labor and rent land. It grows 5 acres of cotton, produces 550 kg of seed cotton per acre, sells for 3 yuan per jin, and produces 1650 per acre. RMB, mu expenditure of 400 yuan, mu yield of 1,250 yuan, 5 mu of total revenue of 6,250 yuan. It only takes more than half a year, and there is no heavy manual labor, and there is still time to go out to work or run other businesses. If the physical strength is strong and the time is more abundant, 10 acres of cotton can be planted, and the income rises to 125,000 yuan. If we can rent another 10 mu of land, the rent is 200 yuan per mu, and the labor cost is 200 yuan per mu, that is, 20 mu of cotton is planted, and the average expenditure per mu is 800 yuan. Although the yield per mu fell to 850 yuan, the total revenue rose to 17,000 yuan. It can be seen that cotton is a good option for increasing income.
2. The cotton breeding technology and variety support several newly-bred breeds of the "Guoxin Federation", and supporting management can basically solve several major cotton planting problems in extreme weather conditions, greatly reducing risks and improving safety. These new varieties will be available in batches next year for farmers to choose from.
Third, do not be extravagant about cotton prices. I think many farmers are entangled with the current low cotton prices. I am afraid they will regret the price increase after selling early. The author believes that it is impossible to reach the previous Khmer price. Because the seed cotton in the hands of farmers is now processed into lint, its fiber length, micronaire value, breaking ratio strength, consistency and other indicators can not reach the mid-range level, and can only be at the lowest end of the purchase price, even "mixed flowers" "Tonghua" level. It is better to work hard next year to greatly reduce the cotton planting investment and cost, and firmly learn the easy cotton planting technology, and you should be able to get a satisfactory income.
1. High accuracy, high stability and high repeatability: meet the measurement accuracy requirements of the measured part.
1) Select high-precision grating measurement system and high-precision inductance measurement system, with high measurement accuracy;
2) Independently researched and developed high-precision grinding guide rail system, which has good wear resistance of guide rail materials and ensures stable and reliable operation of the system;
3) High-performance linear motor drive system ensures high measurement stability and good repeatability.
2. Intelligent management and detection software system:
The operation interface of the instrument is friendly, the operator can easily master the operation of the instrument, and the use is very simple.
1) The company has accumulated many years of practical measurement software design experience to provide customers with simple, practical and fast operation experience;
2) The company has invested many years of human resources in the development of instrument software, with special software copyright;
3) With powerful functions, it can automatically process data, print reports in various formats, and automatically display, print, save and query measurement records;
The data can be archived or printed in a centralized manner, which does not take up the verification operation time;
4) The measurement range is wide, which can meet almost all types of workpiece profile measurement, including special measurement functions of special workpiece screw, bearing, thread and other profiles;
5) The measured section can be selected automatically and manually for evaluation, and software functions can be customized according to customer requirements;
6) Powerful CNC automatic measurement and automatic labeling analysis function;
For large quantities of the same type of workpiece, it can carry out CNC measurement, automatically analyze and process the data, and carry out SPC statistics on the data, and can carry out statistical analysis in various ways to give quality control guidance;
7) It can automatically record and save all verification results by using computer large-capacity database storage.
3. It can also measure surface roughness and contour shape
With the same main body, you can only switch different modules to measure the profile shape and microroughness of the product.
4. Multi-parameter evaluation
The roughness can be automatically evaluated according to different standards, including Ra, Rp, Rv, Rz, Rt, Rmax, Rq, Rsk, Rku, RSm, RPc, Rdq, Rdc, Rmr and P parameters, W parameters, Motif parameters, Rcore parameters and other multi-parameter evaluation.
5. Thickness parameter measurement
When measuring the roughness parameters, the height and thickness of some film steps within 600 microns can be measured simultaneously. The measurement is convenient, and the accuracy is controlled within 2% H (H, the total height of measurement). It is especially suitable for high-precision measurement occasions without scratches.
6. Measuring force system:
With the voice coil motor force measuring system, the force measurement can be continuously adjustable from 10 to 150 mN, and the force measurement resolution can reach 0.2 mN; It avoids the force measurement error caused by the vibration of the surrounding environment when the old weight is loaded, and reduces the measurement error caused by the change of the force measurement.
7. Intelligent protection system:
The instrument is protected by hardware and software in all directions, which can effectively protect the instrument host and probe, and reduce the probe and instrument damage caused by personnel's operation errors.
8. Flexible manual control:
The instrument is equipped with a special separating operating rod, which can be placed at any position to control the operation when the instrument is operated and moved, and the measuring needle can be roughly positioned before measuring the workpiece; In the case of leaving the computer, the operating rod has the functions of moving the measuring needle left and right/up and down, emergency stop, the angle swing of the measuring rod up and down, and multi-level speed adjustment.
