Analysis of Wheat Seedling Growth by Soil Moisture and Drought Management System
The soil moisture and drought management system can provide a comprehensive and accurate analysis of the crop's growing sensation and provide beneficial information for planting crops. This article is mainly for everyone to briefly introduce the analysis of wheat seedling growth management system.
After the emergence of wheat, most regions have high temperatures and low precipitation, and soil moisture and drought management systems analyze drought conditions in western Henan, central Henan, northern Henan, and eastern Henan, and some wheat fields are deficient due to inadequate surface moisture, resulting in lack of seedlings. The ridge phenomenon occurs and has an adverse effect on the growth of wheat seedlings. Soil moisture content in some areas is always at a low level, which is not conducive to the cultivation of strong seeds before winter.
In the late winter, the temperature is low, but the temperature is stable and the amplitude is not large. Because the growth of the wheat is slow and the water demand is small at this stage, the unfavorable moisture condition has little effect on the growth of wheat and is conducive to safe wintering. Soil moisture and drought management system results showed that except for a small number of plots in northern Henan and western Henan, the soil moisture content was adequate, and soil moisture content in most other regions was suitable. The relative soil water content at the sampling site was between 66% and 85%. The lyrical conditions are favorable for the delivery and growth of wheat before winter.
Soil moisture content and drought management system measured the relative water content of 0-20cm soil layer increased by 2.14 percentage points, and the relative water content of 20-40cm soil layer increased by 2.17 percentage points. Compared with the same period of last year, the soil moisture and drought management system monitoring point of 0-20cm soil relative water content average 7.25 percentage points higher, 20-40cm soil relative water content average 2.09 percentage points higher.
According to the overall analysis of the soil moisture and drought management system, the wheat moisture content is lacking after winter, and if there is less rain and snow, the emergence of wheat seedlings is insufficient. Wheat seedlings should be irrigated at this stage.
Construction hoist is vertical transport machinery driving by pinion and rack, mainly used on construction site for transportation of personal and materials. As a permanent or sub-permanent external elevator, it also applies to store house, dock, high tower, high chimney, etc.
There are single cage and double cages hoist. According to the need gets rid of one cage of double cages the hoist will be changed to single cage hoist. SC Construction Hoist is equipped with reliable electrical and mechanical safety device. It is efficient and safety vertical transporting equipment.
Spare parts for a construction hoist may include:
1. Wire Rope: These are used to lift and lower the load in the hoist. They may need to be replaced if they become worn or damaged.
2. Construction Hoist Motor: The motors in the hoist are responsible for powering the lifting and lowering mechanism. Spare motors may be needed in case of motor failure.
3. Electromagnet Brake: The hoist is equipped with brakes to hold the load in place. Spare brake pads or other brake components may be necessary for maintenance or repair.
4. Control panels: The control panel is used to operate the hoist and control its movements. Spare control panels or control panel components may be required in case of malfunction.
5. Safety devices: Construction hoists are equipped with various safety devices, such as limit switches, overload protection, and emergency stop buttons. Spare safety devices may be needed to ensure the hoist operates safely.
6. Bearings and bushings: These components help reduce friction and facilitate smooth movement in the hoist. Spare bearings and bushings may be necessary for maintenance or repair.
7. Electrical components: Various electrical components, such as relays, switches, and fuses, may need to be replaced if they fail or become damaged.
8. Pulleys and sheaves: These components are used to guide and redirect the wire ropes in the hoist. Spare pulleys and sheaves may be required if they become worn or damaged.
9. Hooks and shackles: The hooks and shackles are used to attach the load to the hoist. Spare hooks and shackles may be needed if they become worn or damaged.
10. Construction Hoist Steel Structure parts: Spare structural components, such as beams or mast sections, may be required for repair or replacement if they become damaged or worn over time.
