Description
Technical field
The present invention relates to a kind of soil improvement agent, especially relate to a kind of sandy soil conditioner and preparation method thereof, application.
Background technology
It is exactly desertification that the big area of desertification of land spreads, and is one of the most serious Global Environmental Problems.Desertification of land causes the loss of soil with organic matter and plasma, soil alligatoring, and fertility declines, fertility slump of disastrous proportions, application soil improvement agent is one of important measures of repairing degenerated soil.Soil improvement agent can improve soil physical property and soil nutrient status effectively, and soil microorganisms is produced to actively impact, thereby improves the productivity of degenerated soil.
For example, Granted publication CN101851512B, the Chinese patent of Granted publication day 2013.02.06 discloses a kind of soil improvement agent for sandy land, comprises the raw material of following weight parts: fertilizer 650-750 part, peat soil 220-280 part, water-holding agent 30-70 part.Probiotics in this soil improvement agent in peat can promote organic fertilizer mineral and humify, but the quantity not sufficient per capita of China's peat resource, along with excessive exploitation and consumption to peat resource, cause peat scarcity of resources, cost is higher, it is fast that this soil improvement agent is used rear nutrient releasing speed in addition, keeping fertility is poor, crop is low to the utilization ratio of nutrient, make the application efficiency of this soil improvement agent low, amount of application high (every mu of First Year is no less than 10 tons, and every mu of Second Year amount of application is no less than 5 tons, the 3rd year amount of application every mu be no less than 3 tons).
Summary of the invention
The present invention is that the existing cost of the sandy soil conditioner in order to solve prior art is high, use rear nutrient releasing speed fast, keeping fertility is poor, and crop is low to the utilization ratio of nutrient, the problem that amount of application is large, provide a kind of proportioning scientific and reasonable, cost is low, and safety and environmental protection can strengthen soil fertility and improve prone soil structure, and fertilizer conservation moisture holding capacity is good, there is the sandy soil conditioner of broad prospect of application.
The invention also discloses a kind of preparation method of sandy soil conditioner, preparation method's processing step of the present invention is simple, workable, is applicable to suitability for industrialized production.
To achieve these goals, the present invention is by the following technical solutions:
A kind of sandy soil conditioner, is made up of the component of following weight percent: 2～5% Sodium salts humic acidss, and 20～30% flyash, 5～10% Rhizoma amorphophalli powders, 20～30% dry sheep excrement, 1～3% guar gum, surplus is diatomite.In sandy soil conditioner of the present invention, Sodium salts humic acids the nutrition of providing is provided, improves soil property, promotes the absorption of crop to P fertilizer, stimulate plant growth, strengthen the effect of crop disease prevention resistance against diseases, increasing both production and income, with dry sheep excrement coordinated, can greatly improve the getting fat effect to prone soil, fly ash is abundant, have advantages of that raw material sources are extensive, inexpensive, the treatment of wastes with processes of wastes against one another, in prone soil, add flyash and can effectively improve soil porosity, be conducive to promote the balance of aqueous vapor in soil and increase soil fertility, flyash can also obviously reduce the penetrating quality of sandy soil, weakens sand waterpower transmissibility, Rhizoma amorphophalli powder is a kind of macromolecular compound, there is very strong water-absorbent and water-retentivity, play the effect that keeps soil moisture and chessom, in the time that soil water content is high, it can absorb the moisture in soil and expand, after water suction, the inflatable 80-100 of volume doubly, then can within the ensuing a very long time, discharge moisture, and the moisture major part absorbing can be by plant utilization, can diminish gradually along with the minimizing of moisture in body again afterwards, it is large that therefore distance between soil particle can become, can make loosing soil, Rhizoma amorphophalli powder can be resolved into gradually soil by microorganism after being manured into soil nutrient is provided in addition, to environment without any detrimentally affect, Environmental Safety, dry sheep excrement can change the loose structureless bad proterties of sandy soil, and can improve the organic content in prone soil, improves the fertility of soil, and dry sheep excrement is easy to get, and cost is low, on the molecular chain of guar gum, contain numerous hydroxyls, between hydroxyl on Sauerstoffatom and guar gum on mineral surface, can form hydrogen bond, the prone soil granular cementation disperseing is mutually formed to soil agreegate to improve the stability of soil particle together, thereby play the effect of solid soil, soil conservation, but the add-on of guar gum can not be excessive, otherwise meeting influence aeration of the soil and water-permeable, diatomite has vesicular structure, be applied to after soil can be by most of moisture and Nutrient absorption wherein, and there is the wherein characteristic of moisture and nutrient of slow release, lasting supply crop needs, greatly improve the utilization ratio of crop to nutrient, play the effect of slowly-releasing and synergy, thereby diatomite also can improve the root system development of Soil structure situation promotion crop, in addition, diatomaceous mixing uniformity is good, itself can become concentrated fertilizer, has the effect that impels the aspect such as crop growth, improvement soil.Sandy soil conditioner scientific formulation of the present invention is reasonable, cost is low, safety and environmental protection, by the mutual coordinated between each component, can strengthen soil fertility and improve prone soil structure, and fertilizer conservation moisture holding capacity is good, and the characteristic that can slowly discharge wherein moisture and nutrient is to supply with lastingly crop needs, greatly improves the utilization ratio of crop to nutrient.
As preferably, described dry sheep excrement makes by the following method: after air-dry dry sheep excrement, pulverize and cross 2～4mm sieve.Dry sheep excrement is pulverized, and is conducive to improve plant recovery of nutrient.
As preferably, described diatomite particle diameter is 40～100 orders.Diatomaceous particle diameter is 40～100 orders, and slowly-releasing and synergistic effect are good.
A preparation method for sandy soil conditioner, concrete steps are:
(1) diatomite pre-treatment: diatomite is placed at 400～600 DEG C and carries out naturally cooling to room temperature after roasting 4～6h, stand-by.The present invention adopts the mode of roasting to carry out pre-treatment to diatomite original soil, can remove molecular water and the organic matter of diatomite surface and interlayer by roasting, effectively improve the physical structure of diatomite original soil, make diatomite original soil can keep original structural framework and crimping structure, improve slowly-releasing and synergism performance.
(2) composite batch mixing: take after Sodium salts humic acids, flyash, Rhizoma amorphophalli powder, dry sheep excrement, guar gum, diatomite by said ratio, first Sodium salts humic acids, flyash, Rhizoma amorphophalli powder, dry sheep excrement are mixed with guar gum, then add diatomite to mix.Mix to ensure the homogeneity of mixing by gradation, and can obtain sandy soil conditioner by simple mixing, processing step is simple, workable, is applicable to suitability for industrialized production.
The application of a kind of sandy soil conditioner in the time of improving sandy soil.
Therefore, the invention has the beneficial effects as follows:
(1) sandy soil conditioner scientific formulation of the present invention is reasonable, cost is low, safety and environmental protection, by the mutual coordinated between each component, can strengthen soil fertility and improve prone soil structure, and fertilizer conservation moisture holding capacity is good, and the characteristic that can slowly discharge wherein moisture and nutrient is to supply with lastingly crop needs, greatly improves the utilization ratio of crop to nutrient;
(2) mix and can obtain sandy soil conditioner by gradation, the sandy soil conditioner good uniformity obtaining, and processing step is simple, and workable, be applicable to suitability for industrialized production.
