Description
Technical Field
The invention relates to the field of planting of leymus chinensis, in particular to a no-tillage shallow-sowing seed drip irrigation method for leymus chinensis.
Background
Drip irrigation is the local irrigation of crops by delivering water through plastic pipes to the roots of crops through orifices or drippers on capillaries with the diameter of about 10 mm. It is the most effective water-saving irrigation mode in arid water-deficient areas at present, and the water utilization rate can reach 95%. Compared with spray irrigation, the drip irrigation has higher water-saving and yield-increasing effects, and can be combined with fertilization to improve the fertilizer efficiency by more than one time. The irrigation system is suitable for irrigation of fruit trees, vegetables, economic crops and greenhouses, and can also be used for irrigation of field crops in arid places with water shortage. The water dropper has the disadvantages that the water dropper is easy to scale and block, so that strict filtration treatment is carried out on a water source.
In addition, since the water areas to be pumped are rivers or lakes, aquatic plants grow in the water areas, and garbage often exists in the water areas due to environmental pollution problems, a water filtering grid is often arranged at the opening of the water pumping pipe to prevent the objects from entering the water pipe, so that the drippers are blocked. And among the prior art drainage net often can lead to pasture and water or rubbish winding to make can't continue to intake at the drinking-water pipe mouth of pipe owing to drawing water the in-process, often adopts the method of artifical clearance, and the frequency of required clearance is high if aquatic winding thing is too much, and artifical clearance will be very inconvenient, wastes time and energy.
Disclosure of Invention
The invention aims to provide a no-tillage shallow-sowing drip irrigation method for leymus chinensis, which aims to solve the problem that the pipe orifice of a water inlet pipe is easy to block.
The basic scheme provided by the invention is as follows: the no-tillage shallow-sowing drip irrigation method for the leymus chinensis comprises the following steps:
s1: putting the cleaning end connected with the water inlet pipe into a water pumping area;
s2: sequentially controlling the first water pump and a cleaning mechanism for automatically cleaning a water filtering grid arranged at the pipe orifice of the water inlet pipe to work in a reciprocating mode in turn; when the first water pump works, the cleaning mechanism stops working, and when the cleaning mechanism works, the first water pump stops working;
s3: the water entering the water inlet pipe enters the first water storage barrel communicated with the water inlet pipe, and then enters the drip irrigation emitter for irrigation from the water outlet pipe communicated with the first water storage barrel after being filtered by the filter.
The invention has the advantages that:
in order to reduce the problem that the in-process water dropper of driping irrigation blockked up easily, carried out the secondary in this scheme and filtered, just for the first time inlet tube department drainage net filters, and the second time filters through the filter. The problem of blockage of the dripper is reduced by twice filtration. In addition, the problem that the inlet tube mouth of pipe blockked up easily has still been solved in this scheme, carries out automatic clearance to the drainage net through setting up clearance mechanism in inlet tube mouth of pipe department, avoids the inlet tube mouth of pipe to be blockked up, and the clearance process need not the manual work and goes on convenient to use.
Further, in step S2, when the cleaning mechanism is in operation, the driver in the cleaning mechanism controls the blade fixed on the driver and the water filtering grid to move relatively, and the blade cuts the winding wound on the water filtering grid.
Through the automatic clearance of winding thing on the driver control blade reciprocating motion realization drainage net in this scheme, need not artifical clearance, convenient to use.
Further, when the blade cuts the winding on the water filtering grid, the third water pump arranged on the first water dividing pipe with the pipe orifice arranged right opposite to the water filtering grid starts to work, and the first water pump on the water inlet pipe stops working.
When cutting through the winding in this scheme, the third water pump that the mouth of pipe set up on the first water branch pipe just opposite drainage net begins work, and first water pump stop work, then forms certain adsorption affinity to the winding on the drainage net for winding and drainage net are perpendicular, the better cutting of being convenient for.
Furthermore, after the water flow enters the first water dividing pipe, the water flow enters the second water storage barrel communicated with the first water dividing pipe to be stored, and then the water stored in the second water storage barrel is cleaned and then the fourth water pump on the second water dividing pipe between the second water storage barrel and the first water storage barrel is controlled to work.
Can clear up again after can following the rivers suction to the second water storage bucket with the winding that cuts in this scheme, clean water after the clearance can continue to be used for driping irrigation.
Furthermore, when water flow is required to flow into the drippers from the first water storage barrel, the valve on the water outlet pipe is controlled to be opened, and then the second water pump is controlled to work.
The rivers in the first water storage bucket of valve opening back in this scheme just can be used for driping irrigation, can carry out certain quiet back of putting with the water of depositing in the first water storage bucket promptly for some impurity deposits, later will deposit the clean water in back and drip irrigation again.
Further, before step S1, the water outlet end of the first water distribution pipe is placed to a position far away from the cleaning end.
The water containing the winding materials under cutting in the scheme is directly introduced to other positions of the water pumping area without manual treatment.
