Abstract
A drought-resisting gelationized water for the plant is prepared from polyacrylate (0.1-5 wt.%), carboxymethyl cellulose (0.1-5) and clean water (90-98) through proportionally mixing polyacrylate with carboxymethyl cellulose, adding small-amount of water to wet the mixture, stirring while adding water until it becomes transparent gel, laying aside for 1 hr, adding a little viscosity decrease, stirring and loading in sealed bottles. After used, it can be regenerated by absorbing water.
Description
Technical field
The present invention relates to a kind of drought-resisting solidified water that uses repeatedly and preparation method thereof.
Technical background
China is the country of a lack of water, and damage caused by a drought is more and more serious, desertifies threatening human survival just gradually.Conquer the desert, reduce arid, have only plant trees more, multiple grass, planting trees on barren hills, desert, increase green reservoir, could change arid situation.Will be in the desert of water retention property difference, arid tract kind grass, tree planting not only will solve water, also will improve the soil water conservation.Long-term water supply, plant just can grow up strong and sturdy.But also there is not a practicable method to address this problem effectively at present.Chinese patent 00107121.1 discloses a kind of solid water, but there is following shortcoming in it.One: after the described solid water of this patent decomposes, soil still can not water conservation: its two: at the initial catabolic phase of the described solid water of this patent, because microbiological deterioration does not cause, and makes nursery stock can not obtain the moisture of growing about initial 10 days, survives thereby directly influence nursery stock; Its three: after the described solid water of this patent decomposed, soil still can not water conservation, can not absorb water repeatedly.
Summary of the invention
The object of the present invention is to provide a kind of drought-resisting solidified water that uses repeatedly and preparation method thereof, solving the problem of plant water, and can absorb water repeatedly again when rainy, improve the soil, keep soil moisture, for plant life and growth.
The drought-resisting solidified water that uses repeatedly of the present invention contains weight percent and is:
0.1---5.0% polyacrylate;
0.1---5.0% carboxymethyl cellulose;
90---98% clean water.
Wherein polyacrylate is meant polyacrylic acid potassium or ammonium polyacrylate, granularity 40-60 order.The High hydrophilous resin of suction multiple 500-800%, the water retention capacity effect that increases soil is best.
The carboxymethyl cellulose powdery, granularity 40 orders add water and ceaselessly stir, till the complete transparent clarification of solution after carboxymethyl cellulose is drenched.
Water requires inclusion-free, cleaning, requires sterilization (bacteria containing amount is less than 30).
The preparation method of drought-resisting solidified water: polyacrylate, carboxymethyl cellulose are mixed by weight proportion, after adding less water earlier and making it drenched, constantly stir, slowly add water till a certain amount of, become transparent gel-form, left standstill one hour, and added a little viscosity-depression agent and stir, use the bottle sealed packaging.Viscosity-depression agent can be selected alum for use.
Open bottleneck during use, seeds in the hole, are filled out a soil slightly, bottle is stood upside down in the tree underfooting again, allow solidified water slowly soak into tree root, topped earth reduces water evaporates.Microbiological degradation solidified water, 95% water were kept two to three months by plant utilization.Absorbed by the water-absorbing resin in the soil again if rain, all the time water is remained on around the tree root, make sapling that the moisture of controlled maintenance growth all be arranged every day in the planting season in 1 year, in several years afterwards simultaneously, all the moisture of soil can be remained on around the root system, promote plant root system development,, thereby make the faster growth of nursery stock to the deep subsoil development.Overcome the shortcoming of aforementioned Chinese patent 00107121.1 disclosed solid water.
Embodiment
Below by embodiment the present invention is described in detail:
Embodiment 1:
Get polyacrylic acid potassium 20g, carboxymethyl cellulose (CMC) 200g, clean water 9800g, earlier polyacrylic acid potassium 20g and carboxymethyl cellulose 200g are mixed.Add less water drenched after, constantly stir fast, slowly add entry 9700g, become transparent gel-form.Left standstill 1 hour, title viscosity-depression agent 10g is dissolved in the 100g water, be added in the above gelating soln to stir, and 10 bottles of packing, every bottle of 1kg. sealing bottleneck is opened bottleneck during use, stand upside down then in the middle of ten basin cuckoo flowerpots, builds with earth above.Compare group with ten basin rhododendrons in addition.Only add water one time, do not add whatever.Be placed within doors and observe, after one month, control group is all fallen leaves, and is after second month, all dead.Ten basins that add solidified water are lived well-grown entirely.
Embodiment 2:
Get polyacrylic acid potassium 30g, carboxymethyl cellulose 150g, clean water 9800g, earlier polyacrylic acid potassium, carboxymethyl cellulose are mixed, adding the drenched back of less water constantly stirs fast, slowly add entry 9700g, stir into transparent glue, left standstill one hour, claim viscosity-depression agent 10g to be dissolved in the 100g water, stir 10 parts of packing, every part of 100g.Being used for beating nest broadcasts the every nest of grass seeds (rye grass) and puts 20 grass seeds, a small amount of thin mud of lid.Control group 100 nests, every nest are put 20 of grass seeds, and arid is rain not, put 100 nests of solidified water, and the 4th day begins to germinate, and the tenth day percentage of germination is up to 90%, and control group the 7th talent begins to germinate, and percentage of germination has only 50% after 20 days.
Embodiment 3:
Get polyacrylic acid potassium 200g, carboxymethyl cellulose 300g, clean water 9500g, earlier polyacrylic acid potassium, carboxymethyl cellulose mixed, add less water wet after, constantly stir fast, slowly add water 9500g, stir into transparent colloidal liquid.Be placed in the wooden barrel.Transport to Miao Yuan, dig one meter high pear sapling of 500 strains, earth on the root is removed entirely, coring is immersed in the solidified water solution, soaks a strain and just put together, tie, after depositing 2 days, transport to the hillside, beat nest and plant, irritate sufficient water, survival 458 strains after one month, survive and reach more than 90% control group solidified water solution-treated, surviving rate 5%.The easiest in transit moisture that loses of sapling coring, if be not with earth to be difficult to survive, band earth increases transportation cost again.Adopt solidified water solution to smear coring, solve planting trees on barren hills long-distance transport sapling, improve surviving rate.
