Abstract
The invention discloses a kind of soil phosphorus passivator with rooting promoting for belonging to agricultural technology field.By the material composition of following parts by weight：15 18 parts of water, 25 30 parts of aluminium hydroxide, 25 30 parts of iron hydroxide, 10 20 parts of promoter, 58 parts of compound emulsifying agent, anti-5 8 parts of nematode agent.The passivator can reduce soil quick-effective phosphor, reduce phosphorus element elution risk, simultaneously again can be by the biostimulation of active material, promote plant root growth, crop is reduced to the need for the critical feed consistency of root region soil available phosphorus, and containing some anti-nematode materials, resists nematode, ensure health of root growth, belong to environment-friendly health type soil conditioner；Meanwhile, by the technical matters development such as suspension aids, ultramicro-grinder and high speed dispersor, technique is simple, reduces material Milling volume, and fertilizer stability, homogeneity, mobility are good, it is long time stored it is not stratified, do not precipitate.
Description
Technical field
The invention belongs to technical field of fertilizers, and in particular to a kind of promoting root growth, anti-nematode, regulation and control soil available phosphorus content, drop
Soil phosphorus passivator of low phosphate leaching loss from soil and preparation method thereof.
Background technology
The shallow, beetroot yield of vegetable root layer is small, and the demand to nutrient supply intensity is given birth to apparently higher than field crop, therefore field of vegetables
Focus on very much applying fertilizer in production.Muck has that source is wide, can quickly increase soil fertility and lower-price characteristic, using excrement
Fertilizer has turned into a measure essential during vegetables produce.However, peasant still applies on the basis of muck is largely applied
A large amount of chemical fertilizer, cause all the presence of different degrees of nitrogen phosphorus surplus in almost all of field of vegetables production system.Different from nitrogen, phosphorus element
Easily combined and accumulated with soil mineral in soil, when the increase of soil phosphorus saturation degree, the ability that soil can be caused to hold phosphorus element
Decline, the increase of soil activation phosphorus field of vegetables a large amount and is frequently irrigated in addition, exacerbate phosphorus element elution risk, and then trigger water body
The environmental problems such as eutrophication.Therefore, for high phosphorus accumulation horticultural vegetable field soil, the control of activated state phosphorus element is extremely important, and soil is repaiied
The Passivation Treatment of soil phosphorus is must take into consideration in recovering technology.But, in the soil of the plain level of supply of some higher phosphorous,
Crops seedling stage or increasing the p application rate still is able to make crop yield under Chilling stress environment.To find out its cause, be because low temperature,
Caused by high nutrients accumulation under the adverse circumstance environment such as salt damage, crop root impaired development, nutrient absorption capability is deteriorated, and is supplied for nutrient
Answer intensity requirement higher, dependence is bigger.And often improving crop by increasing the p application rate in actual production Peasants needs phosphorus crucial
Phosphorus element supply intensity under phase and adverse circumstance environment, has in turn resulted in pair of phosphorus content in soil accumulation and crop root growth difference
Weight problem.So also need to consider how to lift plant root growth while considering that passivation soil phosphorus reduces elution loss,
To resist other adverse circumstances.It is passivated in phosphorus element and adds promoting root growth type material simultaneously, promote root growth, improves the absorption energy to phosphorus element
Power, makes its normal growth under relatively low phosphorus element level of supply.In addition, root-knot nematode is that generally existing is asked in soil in protected field
Topic.Root-knot nematode invaded plantses root system, absorbs root system of plant nutrition, and then reduces plant nutrient absorption, ultimately results in plant and declines
Lose or dead.Protection root system of plant is should be noted that while phosphorus element passivation and promoting root growth, from the influence of root-knot nematode, it is ensured that root system
Normal growth.In summary, the phosphorus element passivator with the anti-nematode effect of promoting root growth meets environment and the side of plant growth two simultaneously
The requirement in face, root growth is promoted on the premise of reduction phosphorus element elution risk, and protects root system to be invaded from root-knot nematode, is protected
Demonstrate,proved root system of plant remained under the conditions of the phosphorus element level of supply of Environmental security health it is healthy and strong must grow, with highly important existing
Sincere justice.CN1833789A discloses a kind of phosphor polluted soil restorative procedure, and it is from raw during alum clay smelting alumina powder
Into mine tailing-red mud, crossed 100 mesh sieves, fully mixed with phosphor polluted soil after the roasting 2 hours of 500 DEG C of Muffle furnace, it is used
Measure be per kilogram soil application with 5-15 containing aluminium mMs of red mud, by >=tri- months, completion was once repaired, can fix >=
42% soil available phosphorus.But it does not consider the available phosphorus intensity needed for crop, the supply of crop phosphorus element is likely to result in after not
Foot, causes crop failure.Therefore, the phosphorus element demand of crop is considered as when reducing soil available phosphorus concentration using such product,
With reference to promoting root growth class material and degeneration-resistant class material, increase crop absorbs the ability of phosphorus element while soil available phosphorus content is reduced.
The content of the invention
