Paper Making Pulping And Approach System
This is Paper Making Machine pulping and approaching system, which is working together with paper making machine. It can use raw materials such as wood dust, rice straw, wheat straw, reed straw, cotton stalk etc, from which can make virgin pulp to for the paper making machine to produce different kinds of paper.

The stability of a single probe of the soil moisture quick detector is the premise of the sensor, so the correlation of the characteristics of a single probe under different soil moisture conditions in a single soil type is firstly analyzed. It can be seen that a single probe and probe in a single soil The correlation coefficients are all very high (R2 is above 0.96), reaching a very significant correlation level, and individual sensors are well correlated. The entire experiment began on July 24, when the average temperature was above 35°C. It ended on October 27 and the average temperature was below 20°C. The entire experiment lasted for 96 days. The measurement time was early morning, noon, and evening. The temperature changed. The range is relatively large. It can be seen that the sensitivity of the sensor to the temperature of the plant growth temperature range is low, and the stability of the sensor is good.
From the overall data measured by the soil moisture quickness meter, the sand, loam and clay correlation coefficients are very close, indicating that the dispersion of sensor readings is less sensitive to soil texture. Sand and loam and clay have different opening directions in fitting curve, but loam and clay have the same direction of opening, and most of the soil is between loam and clay, so loam and clay can be used as representative of ordinary soil. Think of loam and clay as a whole.
The rapid and accurate determination of farmland soil moisture is of great significance in ascertaining the profit and loss of soil moisture during the growth and development of crops, so as to make timely decisions on irrigation, fertilization, or drainage measures. The use of TDR (time domain reflectometry) method to measure soil moisture content, can meet the requirements of rapid measurement, real-time, but also improve the accuracy of soil moisture determination (can reach 0.5%), but the moisture meter TDR principle of high price, its It is difficult to popularize and it is difficult to use large quantities in rural soil moisture real-time monitoring and water-saving automatic control systems. Inexpensive soil moisture measuring instrument becomes a top priority.
