Description

Low-cost, multi-functional spout water-saving irrigation system a little

Technical Field

The invention relates to the technical field of water-saving irrigation, in particular to a low-cost multifunctional micro-spraying water-saving irrigation system.

Background

As a country relatively lacking in water resources, China adopts irrigation modes such as drip irrigation, micro-spray, infiltrating irrigation, spray irrigation and the like as common means for water-saving irrigation in modern agriculture. The reasonable design is made according to the water demand characteristics, the growth stage, the climate, the soil conditions and the like of different plants, a corresponding irrigation scheme is formulated, and the maximum benefit can be obtained only through reasonable irrigation in time and in proper amount. Aiming at citrus fruit trees, the commonly used water-saving irrigation technology mainly comprises two water and fertilizer integration technologies of drip irrigation and micro-spraying.

The existing drip irrigation system or micro-spray system, as a whole, mainly includes a water pump, a water source system composed of a fertilizer tank, a filter, various valves, a pressure gauge, a pipeline, etc., a main pipe structure composed of various valves, meters, pipelines, etc., and an irrigation unit (micro-spray mode or drip irrigation mode), as shown in fig. 9, is a typical micro-tank system.

The drip irrigation technology is a technology for dissipating energy of pressurized water and fertilizer through pressure compensation type drippers, arrow insertion type drippers and the like and irrigating crops in a water drop state. The main characteristics are as follows:

water conservation: the water outlet flow of the dripper is small, the flow is 1-8L/h, deep seepage and ground runoff are not easy to generate, only a crop root area is moistened, and generally compared with the traditional irrigation technology, the irrigation efficiency can be improved by 40-50%, the irrigation automation is easy to implement, intelligent irrigation and accurate irrigation are implemented, compared with sprinkling irrigation, the dripper is not influenced by wind and has no drift loss; the evaporation loss is small;

saving fertilizer: the fertilizer for drip irrigation fertilization needs to be a fully soluble fertilizer, the utilization rate of the nitrogen fertilizer can reach 70 percent, is improved by 30 to 70 percent compared with the traditional broadcast application, and the soluble fertilizer is directly applied to the roots of crops, so that the effect is fast;

energy conservation: the working pressure of the dripper is about 1 kilogram, and the working pressure of the sprinkling irrigation system is usually more than 2 kilograms. Therefore, under the same irrigation area, the head working pressure of the drip irrigation system is often lower than that of the sprinkler irrigation system; the water consumption is small, and the total power consumption is less than that of sprinkling irrigation;

saving labor: irrigation management staff are fewer than those required by traditional irrigation;

labor saving: the manual valve or the automatic valve is used for controlling, so that the operation is labor-saving and simple;

land saving: the pipeline can be buried underground by delivering water through the pipeline, and does not occupy cultivated land;

and (3) environmental protection: deep leakage is not easy to generate, and the pollution of the fertilizer to underground water is less;

the disadvantages are as follows:

easy blocking: the section of the flow channel of the dripper is small, and the water outlet hole is small, so that the dripper is easily blocked by organic and inorganic impurities in water, which is physical blockage; if the cation content in the water is high, such as calcium, magnesium and the like, the cation is easy to crystallize in the flow channel to block the dripper, which is chemical blockage; in addition, green moss is often bred in the flow passage to block the drippers, which is biological blockage; therefore, the drip irrigation system must be provided with a filtering system to prevent silt and organic impurities from blocking nozzles and flow channels; there are four common filtration devices:

the sand filter is used for effectively filtering organic impurities in the surface water and is often used as primary filtering equipment;

the sand separator is used for effectively filtering inorganic impurities and is often used as primary filtering equipment;

the screen filter is independently adopted when the water quality is better and is often used as a secondary filtering device;

the laminated filter is independently adopted when the water quality is better, is often used as secondary filtering equipment and is easy to flush.

The requirements for water and fertilizer are high: because the flow channel is easy to block, the requirement on the cleanliness of water quality is higher, and even special treatment is needed for hard water (water with higher cation concentration such as calcium, magnesium and the like); the fertilizer also needs to be completely soluble, the price is higher, and the planting cost is increased;

the facility cost is high: in order to prevent blockage, professional filtering devices such as a sand filter, a lamination filter and the like need to be added, and the whole set of equipment cost is 1200-2500 yuan/mu;

the maintenance cost is high: due to the shielding of weeds around the crown of the orchard tree, the weeds are not easy to find after drip irrigation blocking, manual checking is needed, the workload is large, blocked parts need to be replaced, the cost is continuously generated, and the management cost and the management difficulty are increased;

fixing the irrigation position: the drip irrigation pressure is small, the irrigation range is small, the requirement on fruit trees with developed citrus root systems is difficult to meet, the drip irrigation position needs to be continuously adjusted, the fruit trees grow evenly, and the management cost and difficulty are increased;

the management difficulty is large: prevent the mouse from biting, prevent the injury, prevent stopping up, the explosion-proof pipe.

The micro-spray is a newly developed spray irrigation mode, and is divided into hanging micro-spray and ground-inserting micro-spray. The hanging micro-spraying is particularly suitable for being put into use by trellis type crops (such as grapes and kiwi fruits), the ground inserting micro-spraying is suitable for citrus trees, water is saved compared with general sprinkling irrigation, the hanging micro-spraying is more uniformly sprayed on the crops, and the hanging micro-spraying is used for local irrigation by conveying water through a PE plastic pipeline and spraying through a micro-nozzle. Moreover, the system can be expanded into an automatic control system, and meanwhile, the fertilizer efficiency is improved by combining the application of the fertilizer. The investment of the equipment of the micro-spraying system of the standard greenhouse is generally about 1200 and 1800 yuan.

The micro-spraying has the basic advantages of water saving, fertilizer saving, labor saving, land saving and environmental protection of drip irrigation, mainly overcomes the defects of small water yield, narrow coverage range, fixed drip irrigation position and the like of the drip irrigation in crops with developed root systems and wide distribution, and greatly improves the stress resistance of the economic crops during drought, but still has the defects of high facility cost, management and maintenance cost, high water and fertilizer requirements and the like.

In summary, micro-spraying and drip irrigation realize water-saving irrigation to a certain extent, and an important breakthrough is made on cost reduction, quality improvement and efficiency improvement of modern agriculture, but the problems are as follows:

the facility cost is high: the cost of traditional micro-spraying and drip-irrigation equipment generally exceeds 1200 yuan/mu, a professional installation team is needed, and the agriculture per se has large investment, long period, high risk and slow return, so the high cost becomes a main obstacle for the popularization of the water-saving irrigation technology, however, due to the defect of a new technology, the development of the industry quality is hindered, and a vicious circle is formed.

Weak climate regulation: the traditional micro-spraying and drip irrigation method has small water yield, can only wet soil, has limited effect on improving microclimate around trees, and has unsatisfactory drought resistance effect in extreme arid weather.

The management difficulty is large: the traditional micro-spraying and drip-irrigation equipment room system is complex, needs professional training, is relatively complex to operate, and needs to be cleaned or replaced regularly.

Maintenance problems are complicated: physical, chemical and biological blockage complicates traditional drip irrigation maintenance, and as orchard grass growth becomes a normal state, drip emitters or inserted arrows of drip irrigation are often covered by weeds, which brings great inconvenience to system inspection and replacement, and wastes time, labor and materials. The bypass plastic joint between the branch pipe and the capillary is also easy to be broken by stepping on, and provides more challenges for pipeline design, laying and maintenance.

The use cost is high: in order to reduce the probability of blockage, a fully soluble fertilizer needs to be adopted, and the planting cost is increased.
