Description

A multi-purpose drip irrigation device

technical field

The utility model relates to the technical field of drip irrigation devices, in particular to a device for drip irrigation of crops.

Background technique

As a large agricultural country, my country's agricultural water consumption accounts for about 70% of the country's total water consumption, but the effective utilization rate of agricultural irrigation water is low, and the waste of water resources is also very serious in the case of water scarcity. According to statistics, the effective utilization rate of water in canal irrigation areas is about 40%, and the effective utilization rate of water in well irrigation areas is only about 60%. The average effective utilization coefficient of farmland irrigation water in China in 2017 was 0.542, which means that only 0.542 m ³ of 1 m ³ of water was absorbed and utilized by crops, which is far from the utilization coefficient of 0.7-0.8 in developed countries.

Unscientific irrigation can also easily lead to the loss of nutrients in the soil. For example, the flood irrigation used in most rice fields in China can cause a large amount of nitrogen loss. When fertilizer nutrients are wasted, it will also pollute the surrounding environment of farmland and orchards. Fertilizer loss can also lead to deformed fruit or crops, reduced yields, and reduced nutrient content.

At the same time, the unreasonable use of chemical fertilizers in agricultural production leads to serious soil pollution and nutrient loss, and the fertilizer utilization rate is low, and it is easy to cause fertilizer damage. , Pests and diseases aggravate, wilting, and in severe cases, the whole plant will die. For example, in the autumn of 2014, in a village in Jixian County, Linfen City, Shaanxi Province, 90 bags of compound fertilizer were applied to the 12-year-old Fuji apple orchard at one time, with an average of 1 kg per plant. When applying, a trencher was used to open trenches about 1 meter away from the trunk, and the fertilizers were concentrated. Applied without mixing with soil. The amount of fertilization was "excessive, too close, and too concentrated", causing more than 300 apple trees to suffer from fertilizer damage to varying degrees, 2 to 3 branches on more than 100 trees, and more than 20 whole trees died. Therefore, reasonable fertilization and scientific irrigation methods are particularly important.

At present, the well-known fertilization and irrigation methods are landfill solid fertilizer and surface irrigation method. The fertilization method of landfill solid fertilizer has low utilization rate of chemical fertilizer and is easy to cause soil pollution, not only the consumption of chemical fertilizer materials is large, but also the fertilization effect is not good; The method requires a lot of manpower, and the water loss is serious, not only the watering effect is not good, but also the waste of water resources. In order to solve the above problems, the drip irrigation device came into being. The drip irrigation device can use plastic pipes to send water through the micro-holes or drippers on the branch pipes to the roots of crops for local irrigation, which can be applied to fruit trees, vegetables, economic crops and greenhouse irrigation. , it can also be used for field crop irrigation in dry and water-deficient places. However, the existing orchard drip irrigation device has a complex structure, a large system, complicated installation, and a high overall cost; at the same time, the drip irrigation device is often blocked during use, which brings inconvenience to use; in addition, the drip irrigation device of the drip irrigation device The rate adjustment is unchanged and cannot be adjusted according to the actual situation to achieve a better fertilization effect.

At this time, the drip irrigation pipe 305 and each drip irrigation branch pipe 308 should be installed on the surface of the soil layer or buried in a suitable depth of soil layer.

During the installation process of the drip irrigation device, the main sliding flow controller 22 and each branch sliding flow controller 302 should be in a completely closed state. After the installation is completed, the main sliding flow controller 22 is slowly opened, and the liquid in the liquid storage bag 11 is screwed out. After the water outlet 14 is filtered by the filter screen 19 in the water outlet screw cap 15, it flows through the main water pipe 21 and enters the diverter 25. When the water level in the diverter 25 is higher than each diverter port 26 , slowly open each branch sliding flow controller 302 , and adjust the main sliding flow controller 22 and each branch sliding flow controller 302 to ensure the water level in the diverter 25 It is always higher than each branch outlet 26 and will not overflow. At the same time, the flow rate of each branch water conduit 301 should also be regulated according to actual needs.

In actual use, the number of the diverter openings 26 and the drip irrigation branch pipes 308 can be set according to the type and quantity of the crops that need drip irrigation.

It should be noted that, during the installation process, the horizontal section of the horizontal fixed support 44 should be kept in a horizontal state, so as to ensure that the diverter 25 is in a horizontal state, so that the internal pressure of each branch water conduit 301 is the same.

During the drip irrigation process, it can be judged whether there is a blockage phenomenon by observing the water accumulation in each liquid storage tank 303 .
