It requires little mechanical power and is very suitable for small-area cultivation or garden cultivation. Drip irrigation maintains soil moisture better than other methods without drought or excess water supply. Therefore, it can significantly save irrigation water resources than other irrigation methods.

This irrigation method is to deliver water and nutrients required for crop growth to the roots of crops evenly and accurately at a small flow rate through the pressure pipeline system and the special sprinkler installed on the final pipeline according to the water demand of the crops. An irrigation method on the nearby soil surface or in the soil layer. Compared with surface irrigation, drip irrigation has the characteristics of saving water, increasing production, improving quality, and adapting to soil and terrain. As more and more drip irrigation techniques have been used for growing vegetables in greenhouses in recent years, the shortcomings of this irrigation method have gradually emerged.

In the greenhouse, the drip pipe belts used for crop irrigation are placed on the ground. Due to the arrangement close to the ground, it is necessary to move and protect the drip irrigation belts during inter-plant cultivation on weekdays to prevent large breaks in drip irrigation. It will bring great inconvenience to farming. Especially before sowing every time, the entire drip irrigation equipment needs to be reinstalled, and the drip irrigation belt must be re-arranged. The procedure is complicated and may cause damage to the drip irrigation belt, which greatly reduces the service life of the drip irrigation belt. Finally, the drip irrigation tape needs to be collected, which wastes a lot of manpower and material resources.

These shortcomings in actual operation have restricted the development of traditional drip irrigation arrangements in greenhouses, brought great troubles to people's production activities, and wasted a lot of human and material resources.

detailed description

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

A drip irrigation system for greenhouse crops, as shown in Figure 1, includes a row of concrete columns a2 and a row of concrete columns b6 oppositely arranged under the steel frame of the greenhouse, the concrete columns a2 are arranged on one side of the farmland, and The concrete column b6 is arranged on the other side of the farmland, and the concrete column a2 is higher than the concrete column b6, the distance between two adjacent columns is the same as the row spacing of the crops in the farmland, and the opposite concrete column a2 and concrete column b6 are one group, and the distance between them is the planting length of each row of crops in the farmland;

The wire rope a3 is obliquely arranged between the two opposite concrete columns a2 and b6. On the wire rope a3, a cotton thread 5 hanging down to the ground is arranged at intervals for climbing and growing crops.

A horizontal steel wire rope b8 is also arranged between each pair of concrete column a2 and concrete column b6 set up oppositely, and the dripper belt 4 is arranged side by side with the steel wire rope b8, so that the drip irrigation belt is suspended in the air and does not directly contact the ground. Several sprinklers 11 are arranged on the drip irrigation belt 4, and the positions of the sprinklers 11 correspond to the positions of the crops;

As shown in Figure 2, the drip irrigation belt 4 and the steel wire rope b8 are fixed together by an iron wire 9 and a wire hoop 10, and a wire hoop 10 is respectively arranged on both sides of each emitter 11 to tightly fix the drip irrigation belt 4 and the steel wire rope b8 Together, where the emitter 11 is located, the drip irrigation belt 4 is in a convex shape, so it is necessary to connect the steel wire rope b8 and the iron wire hoop 10 through the iron wire 9, and the iron wire hoop 10 is set on the drip irrigation belt 4, so that the drip irrigation belt 4 and the steel wire rope b8 are fixedly connected together to fix the raised part of the drip irrigation belt to prevent the raised part of the drip irrigation belt from moving upward due to the effect of pressure at the moment of water supply. The irrigator should be as close as possible to the cotton thread, so that the water flowing from the dripper can reach the joint between the cotton thread rope and the ground through the cotton thread rope, which is where the root of the crop is located.

As shown in Figure 3, a water supply pipe b13 is provided on the top of the concrete column a2, and one end of the water supply pipe b13 is connected to the drip irrigation water supply system 1 through the water supply pipe a12, and then the water supply pipe b13 is connected to the drip irrigation belt 4 for feeding the drip irrigation belt 4. Direct water supply.

The working process of a drip irrigation system for greenhouse crops in the utility model is specifically that the water flow is transported from the water source to the drip irrigation belt 4 by the water supply pipe a12 and the water supply pipe b13 through the pressure pipeline system, the filter equipment and the fertilization device, and the drip irrigation belt 4 Above, the water flows out from the emitter 11 arranged on the dropper belt. Since the emitter 11 is very close to the cotton thread 5, a part of the water droplets dripped from the emitter 11 will reach the surface of the leaves and stems of the crop along the cotton thread, and then sink A small water flow along the stem of the crop reaches the root of the crop or drips directly to the root; another part of the water droplets gathers along the cotton thread and flows directly to the connection between the cotton thread and the ground, that is, the position of the root of the crop. These two parts of the water flow reach the roots of the crops to irrigate the crops. Since this design is mainly suitable for the cultivation of greenhouse crops, according to the relevant data, the irrigation volume of greenhouse crops is about 2-5L/h, and because the humidity in the greenhouse is relatively high, water droplets are caused by evaporation during the movement process. The water loss is very small. Comparing this design with sprinkler irrigation, sprinkler irrigation is an irrigation method that sprays a large amount of water on the surface of the crops and then flows to the roots of the crops. However, in this design, the water flows directly to the roots of the crops through two ways, basically does not flow to other places, and the water loss is similar. Insignificant compared to sprinkler irrigation. Therefore, the ratio of the water loss generated in the water flow movement in this patent to the total water volume is very small, and the practicability is very good.

This utility model is applied to the drip irrigation layout of greenhouse crops, creatively placing the drip irrigation belt on the top, reducing the labor when cultivating between plants, and saving the trouble of reinstalling the drip irrigation belt before each sowing, and at the same time It also increases the service life of the drip irrigation belt. The water is led to the soil surface through the cotton thread, and the sprinkler does not directly contact the soil. At the same time, the cotton thread can provide support for the growth of the crops, saving time and effort. The whole system is simple to operate, easy to arrange, high irrigation utilization rate, small footprint, and low construction and maintenance costs.
