China Soil Health Monitoring System Center (http://) is a professional business center engaged in the research and development of soil moisture detection systems. The company has bright and wide production sites, advanced testing methods, and perfect processing technology, and professionally builds high-quality meteorological soil moisture detection systems and other testing equipment.
The soil moisture monitoring system mainly realizes the automatic collection and wireless transmission of soil moisture data under the unattended condition of the fixed station. The data is automatically received and stored in the monitoring center; the 24-hour continuous online monitoring can be realized and the monitoring data can be transmitted through the cable in real time. The wireless transmission method transmits the soil moisture monitoring data to the monitoring center in real time, generates reports and statistical analysis. At the same time, the monitoring center can remotely control the on-site monitoring equipment, so that the staff can grasp the soil condition of the monitoring station in a timely and accurate manner, so as to more comprehensively, scientifically and truly reflect the soil changes in the monitored area and provide effective soil for disaster reduction and drought resistance. Lyric information.
There are four main types of emergency water-saving irrigation methods:
Sit in the water. In the water, water is injected into each seed pit to meet the water requirement for seed germination. The sowing of water is suitable for serious drought, which can not be planted on time and normal emergence or poor soil moisture. The crop emergence rate is low, and it can generally catch up with the rainy season after emergence. In normal years, rainfall basically meets the needs of later growth. The method is to dig or ditch, sit on water, sow, cover soil, and the water injection depth exceeds the planting depth, so as to facilitate the connection with the bottom raft and enhance the drought resistance. The water injection is 2-3 liters per hole, 90-135 cubic meters per hectare. Sit in the water to give priority to the plots that are closer to the water source and then choose the plots that are farther from the water source.
Plastic film acupoint irrigation. It is carried out on the basis of drought-resistant water sowing. After sowing, the mulch film is covered. When the crop emerges quickly to the mulch, the weather is selected and the mulch film is cut into a “ten shapeâ€. After the seedling grows out of the mulch, the seeding pit is expanded into a irrigation hole, that is, the mulch collecting point. When filling, each hole is filled with a small amount of water according to the size of the plant to ensure the survival of the crop. The film collecting point can collect rainwater that falls to other parts of the membrane during rainfall and improve the utilization of rainfall water.
Artificial hole irrigation. If the crop is dry for a long time after emergence, it will seriously affect the growth and development. At this time, if other irrigation measures are not effective, artificial hole irrigation can be carried out to prevent drought and protect seedlings. In the vicinity of the root of the seedling, use a pointed wooden rod with a diameter of 2-3 cm to insert a 20-30 from the ground obliquely to the root. In a cave with a depth of one centimeter, fill the hole with 1-2 liters, then close the hole with dry soil to reduce evaporation. This method can alleviate the drought.
The hose is cast. The use of hoses for water transfer and casting is simple and flexible. Hose water irrigation can climb the slope, pass the ditch and the investment is small, the management is convenient, suitable for a family of drought-resistant irrigation problems.
