Description
Technical field
The invention belongs to antitranspirant fields, and in particular to a kind of preparation method of plant transpiration resistant agent.
Background technology
In recent years, as Large scale drought occur in global warming, northern China and south, many area human livestock drinking waters are tired
Difficulty, due to arid, most of spring-sown crops underproduction or autumn-sown crops cannot be ripe, or even cause Severe Reduction or total crop failure.Agricultural
Always it is to use water rich and influential family as the basic industry of national economy.In China, since water resource spatial and temporal distributions are uneven, basic water conservancy
Facility falls behind, and agricultural irrigation efficiency of water application only has 40% or so, is significantly less than the western developed countries such as the U.S., Israel.Cause
This, improves the water use efficiency of crop vegetation, is the important component part of China's Developing Water-saving Agriculture.The moisture of plant absorption
In by photosynthesis for growth be only 8% or so, and 65% or more moisture is disappeared by the transpiration on plant surface
Consumption, thus reduce the important link that transpiration water consumption is water-saving drought control and drought resistance.In this field, antitranspirant is reducing plant
Great role is played in terms of transpiration, especially in arid area, it alleviates arid to plant to a certain extent
Caused by coerce.
China contains extremely abundant v-ti magnetite ore resources, is mainly distributed on Sichuan and Chengde.It climbs
West is the area that China's vanadium and titanium resources are enriched with the most, and vanadium titano-magnetite prospective reserves is more than 10,000,000,000 tons, wherein vanadium, titanium reserves point
Do not account for the whole nation 63% and 90.5%, point row third place in the world, first.After decades of development, for the profit of vanadium and titanium resources
With having been set up and put forward iron vanadium extraction flow based on blast furnace-converter technique, and titanium work is put forward based on electro-titanium slag technique
Skill.On the basis of the constituent content in raw ore, in prior art flow the recovery utilization rate of iron, vanadium and titanium elements be respectively 63%,
42% and 25%.As it can be seen that the low using level of titanium resource is the key reason for influencing the entire utilization of resources at present.
Up to the present, the antitranspirant of commercialization is varied, mostly chemical type, for its principle, is generally divided into
Three kinds of metabolic pattern, film-type and reflection-type：Metabolic pattern antitranspirant mainly acts on plant photosynthesis metabolic pathway, induces stomata and closes
Close, increase stomatal resistance, to reduce plant by stomata breathe it is rising by be lost to moisture in environment.This type
Antitranspirant main component has mercuric acetate benzene, ABA, fulvic acid etc..Film-type antitranspirant is then to be sprayed by external source, is planting
Object blade surface forms thin film, hinders the moisture loss by way of stomata, this kind of antitranspirant is mainly just like silicone, poly- second
Alkene, polyvinyl chloride and paraffin emulsion etc..Reflection-type antitranspirant, this ideal substance should selectively reflect 400nm with
Lower and 700nm or more invalid photosynthetic radiation, while the rising pressure gradient between temperture of leaves and blade and air is reduced, it reduces rising
Additional water consume caused by heat dissipation, such as aluminium powder, chalk and kaolin.It is real that above-mentioned three kinds of antitranspirants have been widely used in production
It tramples, however, there are also defects：Toxicity is excessive, pollutes the environment；Poorly water-soluble, adhesive force is low, influence light also
Close assimilation.Film-type antitranspirant, reflection-type antitranspirant need the also surface for being sprayed on plant, pass through its insulating effect
Transpiration rate is reduced, therefore, if fountain height is too many, it is possible to by most of air-hole blockage of plant, to influence plant necessity
Photosynthesis and respiration, hinder plant to the absorption of oxygen and the discharge of carbon dioxide.In conclusion developing ecology peace
Entirely, apparent novel antitranspirant is acted on, there is urgent need.
Invention content
The technical problems to be solved by the invention：It is possible to block up at most of stomata of plant for current antitranspirant
Plug influences photosynthesis of plant and respiration, hinders plant to the absorption of oxygen and the discharge of carbon dioxide, toxicity is excessive
