Modern agricultural technology is more and more developed. Many farmers' friends use furrow irrigation when planting crops. But in addition to furrow irrigation, there are other irrigation techniques that everyone should use. What irrigation technologies are there?
1. Micro spray belt irrigation system
We grow wheat and corn by micro-spray irrigation, including water supply equipment and a main water supply pipe installed in conjunction with the water supply equipment, and a micro spray belt installed side by side on the main water supply pipe by means of a valve.
According to the different types and specifications of the micro-spray belt, combined with the water supply situation for hydraulic performance analysis, the water supply equipment and connecting parts are set up to form a complete set of field micro-spray irrigation system, which effectively improves the reliability of the micro-spray irrigation system.
It is mainly used in large-scale grain production, and can be used by grain enterprises and large grain growers, or on contiguous vegetables.
Applicable vegetable types: radish, Chinese cabbage, lettuce, celery, etc.
2, anti-blocking drip irrigation belt
The drip irrigation water is relatively slow. If it is planted in August and September, the drip irrigation should be started in advance. Otherwise, the planting water is too small and it is not easy to slow down the seedlings.
Including the drip irrigation belt, the drip irrigation belt is internally provided with a continuous spiral flow passage, and the water outlet is evenly arranged on the flow passage. The spiral flow channel is used to change the existing drip irrigation channel mode, and has the ability of uniform water discharge and anti-clogging. The water outlet is wide, easy to discharge water, can filter out the impurity sediment in the water, and is more resistant to aging by using cross-linked plastic materials. Low cost features.
The investment under drip irrigation under the membrane is relatively large, and the technical content is relatively high. It is mainly used in the project area mainly based on the production of facility vegetables and the open field vegetable project area with better economic benefits.
Suitable vegetable types: greenhouse cucumber, tomato, eggplant, sweet pepper, strawberry, watermelon, etc.
3, under the film micro-spray
The amount of water discharged from the micro-spray is relatively large. When doing sorghum, it must be made in the form of high on both sides and low in the middle.
It combines the technology of sub-film implantation with the technology of micro-spraying. This micro-spray belt is different from the micro-spray belt on the field, and has special specifications for greenhouse use.
Under-film micro-injection investment is smaller than drip irrigation, larger than furrow irrigation, and the water volume is larger than drip irrigation, but it is much more water-saving than furrow irrigation. It is suitable for facility vegetable project area and some open-field vegetable project areas with good economic benefits.
Suitable vegetable types: cucumber, tomato, eggplant, sweet pepper, lettuce, radish, strawberry, watermelon, etc.
4. New type of irrigation system
It consists of three parts: low-pressure automatic irrigation device, PE pipe water pipeline and underground irrigation pipe. Overcoming the problem of uneven water effluent in China's current percolation equipment, the water volume is too large to control, but the cost of construction is relatively high. Currently, seepage irrigation is mainly used for home vegetable cultivation.
5, quantitative irrigation bag
It consists of two parts: the water conduit and the seepage bag. The percolation bag is a pocket type that is closed at one end. According to the soil water penetration radius, the spacing of the water outlet joints on the bag is determined to ensure that the soil is evenly moist. The water level holes are respectively placed at the upper end of the seepage bag at an angle of 45° and 30° from the top to solve the water demand change in different growth periods. Quantitative problem.
The quantitative percolation bag is suitable for different types of vegetables with row spacing and different growth period applications, and has good practicability. The quantitative adjustment adopts water level hole design, which is convenient and feasible.
According to the survey, at least 80% of farmers in the summer are still using furrow irrigation, and at least 60% of farmers in winter use furrow irrigation. We all know that there will be many problems in furrow irrigation, resulting in high humidity in the shed, serious pests and diseases of vegetables, and wasting water resources. Every irrigation technology has its advantages and disadvantages. In fact, farmers can combine themselves and adopt irrigation technology that suits them.
Medical Mask is a kind of hygiene product. It is generally worn on the mouth and nose to filter the air entering the mouth and nose to block harmful gases, odors, droplets, viruses and other substances. It is made of gauze or paper and other materials. .
The Disposable Medical Mask has a certain filtering effect on the air entering the lungs. Wearing a mask has a very good effect when working in a polluted environment such as dust when respiratory infectious diseases are prevalent. Masks can be divided into 3 Ply Disposable Masks and air-supplied masks.
