Abstract
The invention provides a plant antitranspirant which is a 10-500mu mol/L sodium hydrosulfide water solution. When in use, the fresh plant antitranspirant is prepared as needed and sprayed and applied on the surfaces of stems and leaves of a plant. Compared with the prior art, the plant antitranspirant has the advantages of obvious plant antitranspirant effect, good water solubility, low cost, safety, no toxicity and simpleness in preparation. The plant antitranspirant can simultaneously supplement sulfur (S) and sodium (Na) required for the plant, and plays a role as a foliage fertilizer.
Description
Technical field:
The present invention relates to plant transpiration resistant agent, specifically is that the NaHS aqueous solution is as plant transpiration resistant agent and using method thereof.
Background technology:
Along with the influence of global warming and mankind's activity, water resource has become one of principal element of restriction socio-economic development gradually.In China, agricultural is the basic industry of national economy, but because the distribution of water resources inequality, basic water conservancy projects falls behind, and the agricultural irrigation efficiency of water application has only 40%.And investigation shows, the DESERTIFICATION IN CHINA soil is 2,620,000 square kilometres, is more than 2 times of national total cultivated area, and continues to present expansion trend.Serious ecological crisis makes water resource seem precious more, and the influence each other that takes place frequently of water resources crisis and arid, the common restraining factors that form agriculture and forestry and ecotope.Therefore, efficiently utilize water resource imperative, the modern Technology of Drought-resistant of develop and spread also seems important all the more.Being the agent of development of new plant saving water, resisting drought, improving the water use efficiency of crop preparation, is the indispensable part of China's water-saving agriculture.
Commercial antitranspirant is varied, with regard to its principle, generally be divided into two kinds of metabolic pattern and film-types: the metabolic pattern antitranspirant mainly acts on the plant photosynthesis metabolic pathway, the inducing gas bore closure, increase stomatal resistance, be lost to moisture in the environment by transpiration thereby reduce plant corpus.This type of representative antitranspirant main component has ABA, CaCl2, fulvic acid etc.The film-type antitranspirant then is to spray by external source, forms thin film on the plant leaf blade surface, hinders the moisture loss by way of pore, and the drought resistance agent of this type has kaolin etc.Above-mentioned antitranspirant has been widely used in production practices, but has also exposed a series of problems simultaneously: as toxicity excessive (mercuric acetate benzene), involve great expense (ABA), poorly water-soluble (fulvic acid) influences photosynthesis (film-type) or the like.In sum, the development ecological safety, cheap, the wide and tangible novel antitranspirant of effect of applicability has very strong realistic meaning.
NaHS yet there are no report generally as industrial chemicals as plant transpiration resistant agent.
Summary of the invention:
The object of the present invention is to provide a kind of plant transpiration resistant agent and using method thereof, this plant transpiration resistant agent is sprayed the function that has inhibition transpiration and enriched nutritive at plant surface, thereby strengthen the drought resisting of plant, ability such as degeneration-resistant, reach the purpose of water saving, increasing both production and income.
A kind of plant transpiration resistant agent provided by the invention, it is that concentration is the NaHS aqueous solution of 10-500 μ mol/L, preferred concentration is 50-100 μ mol/L.
Plant transpiration resistant agent using method of the present invention: matching while using system concentration is the NaHS aqueous solution of 10-500 μ mol/L when using, and preferred concentration is 50-100 μ mol/L, and it is sprayed in the plant stem-leaf surface.
The present invention is according to the self-sow of plant seedlings and physiological metabolism characteristics, finishes through the condition test of extensive screening and system.Find that under study for action NaHS is mixed with the certain density aqueous solution to spray in the blade face, its stomatal aperture of control is arranged, reduce the cauline leaf moisture transpiration, reduce the effect that plant moisture scatters and disappears thereby reach.
With the model plant arabidopsis is experiment material, studies show that the obviously stomatal aperture of controlling plant blade of the above-mentioned NaHS aqueous solution, its relative water content contrast increases to some extent, thereby has strengthened the water retention capacity of plant, keeps the water balance in the plant corpus.
Studies show that the above-mentioned NaHS aqueous solution is that NaHS is by slowly releasing H in water
2S/HS
-, exercise the function of its control stomatal aperture.
Compared with prior art, the present invention as plant transpiration resistant agent, resists rising effect obvious to plant the NaHS aqueous solution, good water solubility, and cost is low, safety non-toxic, preparation is simple.Plant transpiration resistant agent of the present invention can also replenish needed sulphur of plant (S) and sodium (Na) simultaneously, has the effect of foliage fertilizer.
Description of drawings:
Fig. 1 is that Arabidopsis leaf sprays distilled water (contrast) and antitranspirant (NaHS) after 6 hours, the microphotograph of its stomatal aperture
Fig. 2 is that Arabidopsis leaf sprayed distilled water (contrast) and antitranspirant (NaHS) after 6 hours, gets blade at random, the comparison of its blade relative water content
Fig. 3 is an arabidopsis continuously in 15 days the process of arid, and blade sprays the comparison that distilled water (contrast) and antitranspirant (NaHS) influence plant growing respectively
Embodiment: below provide non-limiting examples of the present invention.
Embodiment 1. takes by weighing a water NaHS (NaHSH
2O) add the aqueous solution that water is prepared 100 μ mol/L, this treatment fluid is a matching while using.Spray on the live body arabidopsis, observe its blade lower epidermis pore after 6 hours, shown in Fig. 1 (right side), compare with contrast (left side), most of stomatal aperture reduces.
Embodiment 2. takes by weighing a water NaHS (NaHSH
2O) add the aqueous solution that water is prepared 100 μ mol/L, this treatment fluid is a matching while using.On the live body arabidopsis, spray, get blade after 6 hours at random, measure the contrast increase of its relative water content, the results are shown in Figure 2.
In 15 days the process of the continuous arid of embodiment 3. arabidopsiss, blade sprays the NaHS solution of distilled water (contrast) and 100 μ mol/L, the growing state of observation of plant respectively.As seen from Figure 3, the withered speed of the plant leaf blade through spraying is slower, and the survival rate after watering again is higher than control group 60%.
Embodiment 4. takes by weighing a water NaHS (NaHSH
2O) add the aqueous solution that water is prepared 80 μ mol/L, this treatment fluid is a matching while using.Spray on the live body arabidopsis, observe its blade lower epidermis pore after 6 hours, compared with the control, most of stomatal aperture reduces.
By above result as can be known, plant transpiration resistant agent of the present invention can obviously reduce the stomatal aperture of plant leaf blade, increases the relative water content of plant, reaches the good anti-rising effect of plant.
Claims (2)
1. a plant transpiration resistant agent is characterized in that concentration is the NaHS aqueous solution of 10-500 μ mol/L.
2. plant transpiration resistant agent as claimed in claim 1, the concentration that it is characterized in that the described NaHS aqueous solution are 50-100 μ mol/L.
