Abstract
The slow releasing soil water retaining agent consists of attapulgite clay powder, volcanic dust, high hydroscopicity resin and wood dust. It can maintain irrigated water and release water based on requirement of crop and tree, and can also absorb water from soil. The slow releasing soil water retaining agent of the present invention may be used in planting crops and greening plant in drought areas.
Description
Technical field:
The present invention relates to water-holding agent, be specifically related to a kind of slow releasing type water retaining agent for soil.
Background technology:
Plant farm crop and carry out greening and afforestation in the drought and water shortage area, the most important thing is to guarantee the needed moisture of farm crop and arboreal growth, even watered some water at plantation farm crop and the initial stage of carrying out greening and afforestation, and the soil of farm crop and trees ' root moisture most likely, farm crop and trees also are to be difficult to guarantee to survive and normal growth.
Chinese patent grant number CN1114673, Granted publication day is on April 10th, 2002, name is called " nutritional type desert, soil additive ", and it discloses " a kind of planting in desert kind grass nutritional type desert, soil additive relevant with the arid area proportion of crop planting that be used for.Planting trees and grass and proportion of crop planting in desert and arid soil not only need organic and inorganic nutritive element, and need certain moisture especially.The various nutrient substances that plant is required, major part are that the root system by plant absorbs the inorganic and organic composition that is dissolved in the soil and is met, and are the primary conditions that guarantees plant nutrient ingredient transportation and absorption and keep certain moisture in desert and the soil.The present invention relates to absorptive clay mineral wilkinite of having of new Ying and/or zeolite are used as desert, soil additive, this desert, soil additive added to can play suction, water storage in desert and the soil, fix the sand, and can slowly discharge adsorbed moisture and entrained plant nutrient ingredient thereof.”
The weak point of foregoing invention is, the simple employing " has absorptive clay mineral wilkinite and/or zeolite as desert, soil additive ", and moisture that institute can slowly discharge and adsorb is less, is difficult to the surviving rate and the normal growth of the careless and arid area proportion of crop planting of assurance planting in desert kind.
Summary of the invention:
The objective of the invention is to overcome weak point in the prior art, a kind of easy to use, suction and the stable slow releasing type water retaining agent for soil of water retention property are provided.
Slow releasing type water retaining agent for soil is made up of attapulgite clay powder, volcanic ash, High hydrophilous resin and wood chip.
Attapulgite clay be a kind of tool chain laminate structure contain Shuifu County's magnesium silicate clay mineral, attapulgite clay suction, absorption and adhesive property are all relatively good, under aqueous situation, has higher plasticity-, mix the suction back with volcanic ash and High hydrophilous resin and form a kind of gel, increase the intensity of High hydrophilous resin, played the function of water conservation; Volcanic ash is a kind of coarse, lightweight, porous and the higher ore of water-intake rate that the volcanic eruption overflow forms, mineral substance such as volcanic eruption iron that deep under ground is abundant, manganese, nickel, cobalt and trace element take ground to, contain the needed nutrition of many plant-growths in the volcanic ash, be a kind of natural fertilizer, the pozzuolanic place that fell, it is fertile that the soil becomes.The pozzuolanic reserves of China are abundanter, only use in manufacture of cement at present; The water absorbent rate of High hydrophilous resin can reach hundreds of times even thousands of times of own wt, the simple High hydrophilous resin that uses is as water-holding agent, be difficult to give full play to the performance of its high suction, it needs suitable support frame as carrier, just can guarantee the stability of its high-hydroscopicity energy; Wood chip surface irregularity, loose and lightweight, mix suction moisture with attapulgite clay, volcanic ash and High hydrophilous resin after, play the effect of suction, water conservation and support frame jointly, and in soil, form a certain amount of hole, improve water-retentivity, the ventilation property of soil, can not only be well with soil in various micro-the combination, performance water conservation and the effect of minimizing nutrient loss, and can improve the crumb structure of soil, improve prone soil, reduce soil erosion, and then under the prerequisite of improving the ecological environment, promote plant-growth.
The present invention is achieved by following technical proposals:
1, slow releasing type water retaining agent for soil comprises following component by weight percentage: attapulgite clay 20～55%, volcanic ash 15～45%, High hydrophilous resin 1～40% and wood chip 5～25%.
2, the slow releasing type water retaining agent for soil preparation method is: attapulgite clay powder, volcanic ash, High hydrophilous resin and wood chip are mixed and stir, be packaged as finished product after stirring, the water absorbent rate of slow releasing type water retaining agent for soil can reach 20～500 times of own wts.
3, slow releasing type water retaining agent for soil in use, after having watered an amount of water for the first time, slow releasing type water retaining agent for soil sucks its inside with moisture and stores, growth needs according to farm crop and trees, slowly discharge its inner moisture, because the water absorbing properties of attapulgite clay, volcanic ash, High hydrophilous resin and wood chip is stronger, slow releasing type water retaining agent for soil also can constantly suck its inside with the moisture in the soil and store in farm crop and tree-feeding moisture.
4, slow releasing type water retaining agent for soil is under the situation of arid, constantly to farm crop and tree-feeding moisture, rain or situation that soil is moist under, the moisture in the soil is sucked its inside stores.After volcanic ash and wood chip rot, contain the needed nutrition of many plant-growths, be a kind of natural fertilizer, and can improve the structure of soil, make it loose and avoid soil compaction.Slow releasing type water retaining agent for soil can also add fertilizer, chemical fertilizer and trace element as a kind of carrier, to promote farm crop and arboreal growth.
Slow releasing type water retaining agent for soil of the present invention is applicable to arid, lack of water and desertificated area plantation farm crop and greening and afforestation, also is applicable to and cultivates flowers and plants.Slow releasing type water retaining agent for soil, the meeting natural degradation does not have environmental pollution behind the life-time service.
Embodiment:
Below in conjunction with embodiment, the invention will be further described:
Embodiment 1: be used to plant the slow releasing type water retaining agent for soil of farm crop, comprise following component by weight percentage: attapulgite clay 40%, volcanic ash 35%, High hydrophilous resin 5% and wood chip 20%.Attapulgite clay powder, volcanic ash, High hydrophilous resin and wood chip are mixed and stir, be packaged as finished product after stirring, the water absorbent rate of slow releasing type water retaining agent for soil can reach 20～50 times of own wts.
Embodiment 2: be used for the slow releasing type water retaining agent for soil of greening and afforestation, comprise following component by weight percentage: attapulgite clay 30%, volcanic ash 20%, High hydrophilous resin 40% and wood chip 10%.Attapulgite clay powder, volcanic ash, High hydrophilous resin and wood chip are mixed and stir, be packaged as finished product after stirring, the water absorbent rate of slow releasing type water retaining agent for soil can reach 200～500 times of own wts.
