Arid is a global problem, and the grain yield loss that arid causes has exceeded the summation of other natural calamity.Arid, the water and soil loss of semiarid zone, desertification, the salinization of soil three overall situation problem, not only directly endanger production capacity and the stability of North China Dryland Farming system, and injured National Ecological Security construction.In the process to this difficult problem drought-resistant, the mankind have accumulated very rich experience, also achieve significant effect.In recent years, macromolecular material water conservation technology becomes a new direction of dryland farming, Grassland desertification, desert afforestation area technical development, and researchers have also furtherd investigate feasibility and the validity of macromolecule water-loss reducer.But the applying problem of water-loss reducer is never well solved, such as, the consumption of water-loss reducer, the uniformity of applying and depth problem, these all neither one general and efficiently mode go to solve.For this technical deficiency, the tapered material placing device of a kind of biodegradable of the present invention can be good at the different demands met in varying environment, overcomes this deficiency greatly.
Summary of the invention
The present invention proposes a kind of Novel tapered material placing device utilizing the Biodegradable materials such as PLA, poly-own Inner fat, poly butylene succinate and copolymer, PHA, poly-beta-hydroxy-butyrate to make, taper material placing device wall has the micropore of some.Taper material placing device is cone or square cone or other regular polygon cone.When ground moistening, hydrone enters into tapered material placing device by the micropore on tapered material placing device, absorbs a large amount of water and store under the effect of water-loss reducer; And when soil lack of water, hydrone slowly can penetrate in soil through the micropore on these tapered material placing device walls again, and supply root system of plant, reaches the object of water and fertilizer slow release, Promoting plant growth, so that the object realizing agricultural produce, grassland instauration and desert afforestation.
This kind of novel tapered material placing device material therefor is the Biodegradable materials such as PLA, poly-own Inner fat, poly butylene succinate and copolymer, PHA, poly-beta-hydroxy-butyrate, environmentally friendly, without the need to follow-up recycling, slowly decompose under a large amount of microorganism operation in root system of plant after a period of time.Biodegradable material realizes suitability for industrialized production, cheap; The common injection moulding process preparation of tapered material placing device, processing cost is low, is beneficial to large-scale production.
The invention provides following three kinds of technical schemes:
Scheme one: tapered material placing device overall structure is cone shell, and housing opens micropore; The advantage of this scheme is that structure is simple, easy to process; Shortcoming is that capacity is little, the addition of restriction water-loss reducer.
Scheme two: the latter half of tapered material placing device structure is cone shell, and the first half is cylindrical shell, the ratio of two parts height is 1-9:3; The advantage of this scheme is large compared with scheme one of capacity, can store more water-loss reducer.
Scheme three: tapered material placing device structure is the cone shell of tapering change, and lower end tapering is large, and upper end tapering is little, and the ratio of two parts height is about 1:4; What the advantage of this scheme was capacity compared with scheme one and scheme two is large, can store more water-loss reducer.
The front tapering of scheme one and scheme two is less, is suitable for the larger soil of hardness or sand ground; The front tapering of scheme three is comparatively large, is suitable for the less soil of hardness or sand ground.

Accompanying drawing explanation
Fig. 1 is the cross section structure schematic diagram of the tapered material placing device scheme one of a kind of biodegradable of the present invention;
Fig. 2 is the cross section structure schematic diagram of the tapered material placing device scheme two of a kind of biodegradable of the present invention;
Fig. 3 is the cross section structure schematic diagram of the tapered material placing device scheme three of a kind of biodegradable of the present invention.
Embodiment
First according to rainfall and the evaporation discharge on project implementation ground, the size of tapered material placing device and the size of micropore and quantity is determined.
If project implementation ground annual rainfall is larger, year evaporation discharge is less, the water conservation dosage then must put in tapered material placing device is less, and soil is required less by the water yield of tapered material placing device slowly-releasing, therefore can the tapered material placing device of selection of small size and the micropore of large-size, the quantity of micropore can be lacked.
If project implementation ground annual rainfall is less, year evaporation discharge is larger, the water conservation dosage then must put in tapered material placing device is larger, and soil is required larger by the water yield of tapered material placing device slowly-releasing, therefore must select the tapered material placing device of large-size and the micropore of reduced size, the quantity of micropore should be more.
Then the shape of tapered material placing device is selected according to the soil on project implementation ground or the hardness situation of sand ground.
If be the project implementation comparatively arid area, in soil or sand ground, the grains of sand are less, and have certain water content, the hardness of soil is higher, at this moment should select scheme one, as shown in Figure 1, or scheme two, as shown in Figure 2, tapered material placing device shape.Its tapering is less, is beneficial to the soil or sand ground that insert this type of character.
If be the project implementation unusual arid area, in soil or sand ground, water content is extremely low, causes the hardness of soil or sand ground less, at this moment will select scheme three, as shown in Figure 3, tapered material placing device shape.Its front tapering is large, and comparatively scheme one and scheme two are larger for the rigidity of tapered material placing device, are not easy to cause distortion because resistance is large when inserting soil or the sand ground of this type of character.
After determining size and dimension, Biodegradable material is utilized to process the tapered material placing device of requirement.Again according to the project implementation ground weather, soil or many-sided composite factor such as sand ground condition, the root system of plant degree of depth, determine the density that tapered material placing device is placed in soil or sand ground, the degree of depth of area and insertion soil or sand ground.
The operation principle of tapered material placing device is as follows: put into tapered material placing device after being mixed according to a certain percentage with chemical fertilizer, organic matter, soil etc. by a certain amount of water-loss reducer, then assigned enter in soil or sand ground by certain density and the degree of depth by tapered material placing device.Soil or sand ground moistening time, hydrone enters into tapered material placing device by the micropore on tapered material placing device under the effect of water-loss reducer, stores; When soil or sand ground lack of water, hydrone can penetrate in soil or sand ground through these micropores again, and supply root system of plant, reaches the object of Promoting plant growth.
