Abstract
A water-supply moisture-preserving bag for planting plants in dry land or desert is divided into an upper layer for storing water and a lower layer with a water-permeable membrane in-between for separation. The lower layer contain an ultrahigh hydroscopic resin wrapped by a water-permeable sheet. After water is absorbed by the said resin, the resin gradually expands to block the water hole on the bottom. When it is put in a dried soil, the water can be slowly released into the soil for surviving plants.
Description
Technical field
The present invention relates to the automatic watering technical field on plant (forest, fruit tree and meadow etc.), the device and the technology for the plant root feedwater of cistern particularly arranged, this device has used the macromolecule super strength water absorbent.
Background technology
Contain enough moisture in the soil and be one of essential condition that plant planting survives.Watering apparatus and technology have had very great development at present.Pot water, soil moisture conservation technology have had considerable report: is in the basin seat water receiver to be arranged as application number for the technology that 93206266.0 Chinese patent provides, and supplies water with the siphon capillarity of special cotton rod; 96110213.6 Chinese patent then be that basin describes in the device that many facilities such as the microscope carrier of falling the bowl-type, air pump, controller are arranged; Also have the similar patent of considerable part in addition, but can only use in potted plant or garth scale, the quite complicated cost of the device that has is higher.It is just much more difficult to water, preserve soil moisture when implant mass, particularly serious water shortage or desert region plantation trees, straw or like vegetable, and the Chinese patent as 01204827.5 is the annular staving water storage of using around tree, and the bottom has weeper to supply water to guarantee that sapling survives.This class is watered and will be wasted water unavoidably, because the uncontrollable water flow velocity of weeper.01122261.1 Chinese patent then be in tree well, to beat deep hole, insert the antiseepage fistulae, stealthy water storage material is arranged in the pipe, antiseepage water conservation on every side ... tree root can not be got well at last soaking effect descending can to imagine water, besides how enough is low amounts of water in the pipe? in recent years, a large amount of absorbent material occurs that plantation provides Available Material to punja.As in the bullet under the 00123246.0 Chinese patent use water butt Sponge being arranged, its below has apopore to carry out infiltrating irrigation.Yet the Sponge water absorption is limited, has press water just to be extruded slightly, and water was still not dirty after Sponge had water retention and suctions water in addition, how to control effective water supply? the suspicion of wasting water is arranged; Secondly, storage can't be degraded underground, how to dispose, and how a large amount of harm soil that use handle all requiring study after bucket uses.02113922.9 Chinese patent then be that to propose with water-soluble film the high-efficiency water-absorbing resin to be made the water conservation bag be that nursery stock is executed water, water conservation, also seed can be wrapped into wherein, be used for breeding, grow seedlings, it is survived.But reservoir storage of this water conservation bag is limited, and how about discharging preserves soil moisture if being over, the big cost height of water-absorbing resin consumption, restriction practical application.
Summary of the invention
At the deficiency that above-mentioned prior art exists, the present invention aim to provide a kind of can the long period continuously, the soil moisture conservation bag of supplying water for the plant species root automatically and abstemiously.
The soil moisture conservation bag is the bag shape that a kind of plastic foil is made, and interior branch is two-layer up and down, has film to separate therebetween; Lower floor is the suction part, and the built-in sheet material of being made by seepy material is wrapped in super-strong moisture absorbing resin, and its permeable sheet material is nonwoven or the paper of being made by macromolecular fibre; The upper strata is the water storage part.Permeable hole is all arranged at membrane layer between levels and suction part bottom, and its structure as shown in drawings.Size, the quantity of soil moisture conservation bag size, shape and permeable hole depend on the needs.When there was water on the upper strata, water entered lower floor by the permeable hole of interlayer, saw through permeable sheet material and was promptly absorbed by super-strong moisture absorbing resin, and expanding rapidly in resin suction back, just this permeable hole is blocked (even blocking) when expanding into to a certain degree, and stop current to lose; This moment, because super-strong moisture absorbing resin has the characteristic of moisture absorption, water conservation, moisture releasing, the water of being inhaled just slowly and constantly moved to dry soil layer from water-absorbing resin, to reach wetting result as it is inserted in the heatable adobe sleeping platform.Seepage velocity is relevant with the soil moisture content size, and the more little infiltration of soil moisture content is just fast more; Otherwise the big more seepage velocity of soil moisture content is slow more, and the infiltration process carries out using up until whole water, and the soil moisture conservation bag contracts flat, is buried by soil.If degradation material is degraded disappearance gradually then.The infiltration process is located successively all the time, dynamic equilibrium state, makes the certain water content of plant root soil conservation in cultivating into current, survives to guarantee it.For the suction of bag bottom that guarantees to preserve soil moisture partly has a shape relatively, also can outside parcel super-strong water-absorbing material seepy material, add all (six faces) or part infiltration pad (or bag), to play certain supporting role.Material therefor: the sheet material of soil moisture conservation bag, seepy material, super-strong water-absorbing material, infiltration pad (or bag) all are that macromolecular material is made, and preferably degradable macromolecular material is made, and can not work the mischief to environment like this.(Zou is auspiciousness to write at " super strength water absorbent ", Chemical Industry Press, version in 2002) author has had detailed introduction to super strength water absorbent in the book: super-strong moisture absorbing resin water absorption is tens times and even thousands of times of this height often, and the suction back forms hydrogel, has good water retention capacity.Moreover, the water of this aqueous gel has good mobility in soil, and the gel moisture content is big more, and the translational speed of moisture is fast more, and the distance that reaches is far away more.Can think that soil and hydrogel moisture gradient (difference) are big more, moving of water also can be fast more.This superpower suction resin and common foamed plastics (as polyurethane foam) have very significant difference, and foamed plastics can absorb water, but water absorption is less, and do not have moisture capacity and press a little immediately the water that absorbs is extruded.Because high-strength absorbing material water absorption is big, and has moisture capacity, can not be extruded because of impressed pressure makes water, and the upper strata also has a certain amount of water storage, so soil moisture conservation bag supplies water the time of soil moisture conservation longer, the big I of soil moisture conservation bag decide as required, the soil moisture conservation time can reach 30 days even for more time.The soil moisture conservation bag can answer instructions for use to make different shape: square, rectangle, flat, even the garden shape of middle (trunk passes) with holes, but its interior all is as described above.This soil moisture conservation bag is specially adapted to arid area kind tree, can put the soil moisture conservation bag that is filled water and water storage is arranged above the usage tree root that covered part soil, and earthing is to ground level (or above ground level) again.Fix the sand the area at needs and survive to guarantee kind of a grass with the soil moisture conservation bag when planting grass, at this moment the soil moisture conservation bag can be made strip, be placed with water soil moisture conservation bag in grass seeds (or turf) both sides, can protect grass and survive.Kind of grass the time is trellis or nettedly then plants grass for well again if survive in grid, as survives and promptly be expected to fix the sand achieving success.
The soil moisture conservation bag can also add various water-soluble fertilizer, nutrient composition and desinsection, weed killer herbicide except that supplying water, help plant growing and kill soil insect after slowly entering soil, and kill and remove unwanted weeds.
The present invention compared with prior art is characterized in: (1) soil moisture conservation bag has water storage and suction two parts, and when suctioning and store enough water, the total amount of water is more relatively, and the soil moisture conservation time also can be longer, and this survives favourable to plant species; (2) the most outstanding is the soil moisture conservation superiority that bag constructions had: super-strong water-absorbing material is in the soil moisture conservation bag, the imbibition and the flat Volume Changes that contracts that seeps water, can be automatically in the infiltration process, low-keyedly carry out continuously, both kept soil moisture content better, do not waste water again; (3) simple, inexpensive, effective product is that prior art is incomparable.
