Abstract

The utility model relates to a root infiltration irrigation device of the delayed root infiltration of stored water for woody plants, which comprises a water pump (1), a water delivery dry pipe (2), a filter (4) and a fertilizer tank (3), wherein, the water delivery dry pipe (2) is provided with a branch pipe control valve (5), a water distribution branch pipe (6), a water inlet pipe (7), a water storage tank (8), etc. The delayed root infiltration of stored water can cause the irrigation water to have no evaporation from land surface or deep leakage, so the irrigation efficiency and the uniformity of water infiltration are enhanced, the effects of water saving and energy saving are obvious, water, fertilizer and gas are favorably absorbed by a root system of a plant, and the utility model provides a feasible infiltration irrigation device for enhancing the yield of fruitage and improving the quality of the fruitage.

Description

Woody plant water storage time-delay root filtration irrigation device

The utility model relates to a kind of agricultural filtration irrigation device, is specifically designed to woody plant infiltrating irrigations such as fruit tree, flowers, nursery stock, specifically a kind of woody plant water storage time-delay root filtration irrigation device.

China's lack of water, particularly North China, the Northwest's serious water shortage have been well known fact.The development water-saving irrigation has become the major action of national common recognition and national development agricultural.Still most ofly in the irrigations such as current fruit tree, flowers, nursery stock adopt the ground flood irrigation and adopted microspray irrigation and drip irrigation on a small quantity.Ground flood irrigation serious waste water resource should thoroughly be eliminated; Though and microspray irrigation, drip irrigation are than ground flood irrigation water saving obviously, also have more shortcoming: (1) equipment investment is big, as surplus every mu 2000 of the overseas equipment yuan, is difficult to promote; (2) shower nozzle, water dropper very easily stop up, and are difficult to maintenance management; (3) microspray irrigation, drip irrigation, water droplet spray be to ground, the upper soll layer high humidity, and evaporation loss is still bigger, and mu is poured water and is still needed 15m ³About; (4) pipeline and spray, water dropper spread on ground, influence other operations, are easy to infringement and aging; (5) because irrigating water quota is higher, and spray, the drip irrigation intensity of pouring water is low, once pouring water takes length, irrigation efficiency is low; (6) need certain spray, the pressure of dripping, energy consumption is higher.Such as above shortcoming, microspray irrigation, drip irrigation are promoted very undesirable in production practices.

The purpose of this utility model just provides the management of a kind of small investment, easy care, long service life, and irrigation water had not only had evaporation from land surface but also do not had the water saving of deep percolation, low energy consumption, irrigation efficiency is high and the quality of pouring water is high water storage time-delay root filtration irrigation device.

The utility model is to realize like this, it comprises water pump, delivery main and filter, and the side connects fertilizer spreading tank on delivery main, its main points are to connect with range pipe by the arm control valve on the delivery main, range pipe connects with several water inlet pipes, each water inlet pipe connects a water storing tank, water storing tank top is connected to the ventilation surge pipe, be provided with float in the water storing tank and connect with filtering type voltage stabilizing water inlet head, filtering type voltage stabilizing water inlet head connects with annular anti-blocking soakaway trench by one section thin short tube, have the infiltration flow regulator on the thin short tube, outside water storing tank, the import department of annular anti-blocking soakaway trench upwards is connected to water level displaying tube.

Be described in detail the utility model below in conjunction with accompanying drawing.

Fig. 1 is the utility model general structure schematic diagram;

Fig. 2 is the user mode schematic diagram of Fig. 1.

As Fig. 1, shown in Figure 2, water pump 1 can take out irrigation water and make it to flow into the delivery main 2 from the water source, if irrigate in conjunction with fertilising, the liquid fertilizer that available head formula fertilizer spreading tank 3 will melt adds in the entry, after irrigation water filters removal impurity through filter 4, enter each range pipe, as open arm control valve 5, irrigation water promptly flows into range pipe 6, and through each water inlet pipe 7 each water storing tank 8 of injection, along with water level in the jar rises, air is discharged to outside the jar through ventilation surge pipe 9 in jar, because the ground level of living in of each water storing tank in the orchard on the same range pipe changes, by this ad hoc transparent ventilation surge pipe 9, the earlier water-filled water storing tank water level that is positioned at lower is risen and unlikely spilling water causes waste along pipe, the water tender can only observe the surge pipe water level of the water storing tank that is positioned at eminence, know promptly whether the water storing tank that is connected with this arm all is full of, if completely this arm control valve 5 can be closed.Open next arm control valve immediately, by next bar arm and connected the water storing tank water-filling.Level sensor can be set in this operation and magnetic valve is realized control automatically.Water storage in the water storing tank, can be by float 10 floating filtering type voltage stabilizing water inlet of drawing an annular soakaway trench 13 of 11 inflows, the float size is with the weight-matched of filtering type voltage stabilizing water inlet head, so that water inlet is positioned at the following 10mm of the water surface all the time, thereby keeps the water inlet water pressure invariableness and guarantee to get the into heavy clear water in top layer.The permeable non-woven filter cloth of filling adds that again the water inlet section is bigger in the water inlet head, and flow velocity is less, therefore can guarantee to enter the water free from admixture of soakaway trench, and stifled in can not causing.Filter cloth in the filtering type voltage stabilizing water inlet head, visual inner bucket water matter and the amount of filtering out impurities periodic replacement.The effect of infiltration flow regulator 12 is, but regulated at will seepage velocity as requested, as one jar of water (about 25Kg) is slowly dripped to around the main root system of trees with delaying time, generally can be transferred to 4-5 days.The anti-blocking soakaway trench 13 of annular generally is embedded in below ground 20-40cm around the main root zone of trees, its textural soil obstruction that prevents that traditional infiltrating irrigation from causing because of negative pressure in managing.Water level indicator tube 14 is located at the water storing tank outside, need not open cover and promptly know a jar interior last water yield, thereby can judge seepage velocity.

Outstanding advantages of the present utility model is, (1) irrigation water does not only have evaporation from land but also do not have deep percolation, and all moisture slowly, to be seeped into main root zone be that plant absorbs in time-delay, the fruit tree mu only 4m that pours water³, also save than current microspray irrigation, drip irrigation Water is more than 60%; (2) reduce investment outlay more than 60% than external import micro-irrigation equipment; (3) can not stop up, be easy to management, be embedded in soil In aging slow, surpass other micro-irrigation equipments service life; (4) good uniformity of pouring water is not subjected to that the ground discrepancy in elevation changes, pipeline head The impact that terminal pressure changes, every tree gained pondage is consistent; (5) water-filling in the tank in short-term, time-delay is filled with to the root infiltration Irrigate efficient and pour water the quality height; (6) the water storage tank is embedded in below ground, and the required hydraulic pressure of water-filling is lower than slight irrigation, and energy-saving effect is obvious; (7) plant root water, fertilizer, gas, heat condition are good, promote microbial activity, and be beneficial to root system of plant and absorb water, fertilizer, gas, Improving fruit eats output and improves its quality.
