Sprinkler irrigation and micro-irrigation automatic control equipment With the development of economy, water resources, energy shortage and labor cost increase, more and more water-saving irrigation systems will adopt automatic control. This article focuses on the advantages and classification of automated irrigation.

The advantages are as follows:
(1) It is possible to truly control the amount of irrigation, irrigation time and irrigation cycle in a timely and appropriate manner, thereby increasing crop yield and significantly improving water utilization.
(2) Saving labor and operating expenses.
(3) The work plan can be arranged conveniently and flexibly, and the management personnel do not have to go to the field at night or other inconvenient time.
(4) Since it can increase the effective working time every day, the initial capital investment in pipelines, pumping stations, etc. can be reduced accordingly.
classification:
First, fully automated irrigation system
The fully automated irrigation system does not require direct human involvement. The pre-programmed control procedures and certain parameters that reflect the water requirements of the crop can automatically open and close the pump for a long time and automatically irrigate in a certain order. The role of the person is simply to adjust the control program and overhaul the control equipment. In this system, in addition to emitters (heads, drip heads, etc.), pipes, fittings, pumps, and motors, it also includes central controllers, automatic valves, sensors (soil moisture sensors, temperature sensors, pressure sensors, water level sensors, and rain sensors). Etc.) and wires.
Second, semi-automatic irrigation system
In the semi-automated irrigation system, no sensors are installed in the field. The irrigation time, irrigation volume and irrigation period are controlled according to pre-programmed procedures, rather than feedback based on crop and soil moisture and meteorological conditions. The degree of automation of such systems is very different. For example, some pump stations implement automatic control, and some pump stations use manual control. Some central controllers are only one timer with simple programming function, and some systems have no central control. The controller, but only some of the sequential switching valves or volume valves are installed on each branch pipe.
Automated irrigation is the trend of the times. In the future water-saving irrigation projects, more and more automated irrigation systems will be applied.
Nanguo pear storage technology
1. The product must be completely sterilized and sterilized before entering the storage. The new type of warehouse smoke disinfectant developed by the center can be used, 500 grams per 100 cubic meters. 2. The harvest period in Liaoning Province can be carried out on September 10-25. The later the harvest, the better the coloration. The higher the sugar content, the better the flavor. 3, before entering the storage should be strictly selected to remove the pests, spotted turtles, mechanical injury of the fruit. 4. Bagging and packing under the tree, put 65cm 65cm, 0.03mm thickness of moisture-proof moisture-proof PVC plastic bag into the packing box, and then load 10 pounds of Nanguo pear (5 kg ) Put 3 sachets of red medicine (physiological regulator) in the upper part, pull it back, and never tie it. If 7070 centimeters is used, 20 pounds (10 kilograms) of Nanguo Pear can be loaded, and 6 packets of red medicine (physiological regulator) can be placed in the upper part. 5, it should be transported into the storage warehouse for storage immediately. There should be 1 to 2 centimeters between the box and the box, 10 centimeters between the box and the wall. The floor must be 10 centimeters high. The box must not be placed directly on the ground. 6, temperature, humidity management should be appropriate, the temperature should be controlled at 0 °C 0.5 °C, relative humidity of 85-90%. Note: If you want to make Nanguo pear yellow when the library is out of storage, do not become soft, after the Nanguo pear into the plastic bag into the packing box, be sure to open the bag mouth, at room temperature for 5 days (never more than 5 days ), and then into the cold storage, after 24 hours of pre-cooling, add red medicine, pull the mouth, never Zhakou.
