Description
Technical field
The invention belongs to plant growth regulator fields, and in particular to a kind of plant for mitigating rice seedling injury from low temperature is raw
Long conditioner and its application.
Background technique
Agricultural production height relies on synoptic climate condition, is that climate influences most sensitive industry.Genus Oryza thermophilic crops,
It is very sensitive to temperature, it is likely to that chilling injury occurs in the different times in paddy growth stage, especially with sprouting stage, seedling stage, pregnant
Ear period and flowering and grouting phase are most sensitive：(such as Seedling Stage, boot stage and flowering and grouting phase), can cause one to rice growth
Fixing is rung, and rice a large amount of underproduction can be caused when serious.According to statistics, over nearly more than 40 years, once there are 8 grievous injuries in the Northeast
Year, wherein 1969,1972 and 1976 are the most serious, and annual 5780000 t of the underproduction of 3 annuals, underproduction rate 20%.
In south, early rice sowing time temperature is lower, and seedling stage usually there is also cold spell in later spring；Early rice Direct-seeding Rice is answered in recent years
With causing rice seedling chilling damage to get worse.Seedling stage low temperature can make rice seedling chlorosis, withered or even dead, reduction water
The growth and tiller of rice root, stem and leaf are the key that the injuries of rice delaying type to influence the time of subsequent each growth phase
Phase.With the acceleration of global industry process and the adjustment of Rice cropping systems, the generation that abnormal temperature endangers crop production
Frequency and the extent of injury are also continuously increased.Therefore, abnormal high temperature guard technology and product research are carried out, it appears it is especially urgent, it is right
The development for promoting Rice Production continual and steady is significant.
Summary of the invention
It is an object of the invention to, by the serious status of injury from low temperature, provide a kind of mitigation water for the current rice seedling phase
The plant growth regulator of rice seedling injury from low temperature, the regulator are made of the raw material of following weight proportion：Compound amino acid
25-50 parts, 5-15 parts of nano silica, 10-50 parts of dispersing agent.The dispersing agent is graphene.Wherein count by weight ratio
It calculates, compound amino acid：Nano silica is 0.2-0.5:0.05-0.2.It calculates by weight ratio, compound amino acid：Nanometer two
Silica：Dispersing agent is 0.2-0.5：0.05-0.15：0.1-0.5.
It preferably calculates by weight ratio, compound amino acid：Nano silica：Dispersing agent is 0.3：0.08：0.3.
A second object of the present invention is to provide the plant growth conditioners to answer in mitigating rice seedling injury from low temperature
With being achieved through the following technical solutions：
Using the aqueous solution of plant growth conditioner, wherein compound amino acid 20g/L~50g/L, nano silica
5g/L~15g/L, graphene special type dispersing agent 10g/L~50g/L；By aqueous solution after rice transplanting, seedling stage low temperature arriving preceding 2
Its 100 times of progress foliage-spray of dilution, sprays primary, application 3-4 times, dosage 45-60 liter/mu for every 3 days.
Preferably, in the aqueous solution of the plant growth conditioner, compound amino acid 30g/L, nano silica 8g/
L, graphene special type dispersing agent 30g/L.
Compared with prior art, the invention has the advantages that：(1) nano silica is with particle size
Small, the features such as micropore is more, large specific surface area, the adsorbed hydroxyl content height, ultraviolet light, strong visible light and infrared-reflecting power.Benefit
Silica can be made to be dispersed in aqueous solution with nano-powder dispersing agent, it, can using the reticular structure of porous silica
Layer protecting film is formed in blade surface, there is antibacterial, permeable, light transmission and heat preservation property, effectively mitigate blade injury from low temperature
(2) plant growth conditioner of the invention can effectively supplement the small molecule amino-acid nitrogen that rice is easy to absorb, and nano-silica
SiClx greatly shortens the growth cycle that amino acid nutrient enters rice leaf in conjunction with small molecule amino acid, has and maintains blade
Premeabilisation of cells pressure balance promotes root activity and tiller, improves Rice Photosynthesis and increase the effect of yield, can be used as often
The Plain or alpine region that meet with seedling stage low temperature maintain the new plant growth regulator of rice high yield stable yields.(3) it is demonstrate,proved through test
Real, rice seedling phase injury from low temperature can significantly be mitigated by correctly applying the plant growth regulator, increase effective tillering and blade
Photosynthetic rate, compared with the control increasing production of rice 6.5-10.2%.
Specific embodiment
Present invention combination following specific embodiments, are described in further detail.It should be understood that described herein
The specific embodiments are only for explaining the present invention, is not intended to limit the present invention.
Embodiment 1
2015, China Paddy Rice Inst of Fuyang City of Zhejiang Province phjytotron, kind：Excellent No. 1 of middle Zhejiang.Rice seedling moves
Plant after a week after 10 days or so (18 DEG C, daytime；10 DEG C, at night) injury from low temperature weather.Such as table 1, after rice transplanting, seedling
The medicament of the preceding 1 day foliage-spray various concentration proportion of phase low temperature arriving, handling T1 is clear water control, sprays within every 3 days once, applies
3 times, 50 liter/mu of dosage.Shown in its experimental result table 1：
Influence of the different agents weight proportion to rice leaf physiological property under table 1, seedling stage cryogenic conditions
Note：There is same letter person to indicate not significant in 5% horizontal upper difference in every column data.Experimental plot area=
1.0m2。
The result shows that phase, the plant growth conditioner of different formulations show to increase Photosynthetic Rate at high temperature
Effect, and significantly reduce the blade level of lipid of low temperature induction.
Embodiment 2
On the basis of cell greenhouse simulation test in 2015 of embodiment 1,2016 at China Paddy Rice Inst test site
The area Liao great comparative test is carried out, each component concentration proportioning is as shown in table 2.Seedling Stage hypothermal injury is simulated using interval sowing mode
Evil, rice seedling transplanting after a week after 10 days or so (18-20 DEG C, daytime；10-12 DEG C, at night) injury from low temperature weather.Water
Rice transplanting after, seedling stage low temperature arrive preceding 2 days progresss foliage-sprays, wherein processing 2-9 be chemicals treatment, processing 1 be clear water control,
Spray within every 3 days primary, application 4 times, 50 liter/mu of dosage.Rice maturation harvest surveys production.
Influence of the different agents weight proportion to rice yield under table 2, seedling stage cryogenic conditions
As known from Table 2, processing 2-9 average yield per mu is 647.5 kilograms, and the per mu yield of clear water control 1 is 598.7 kilograms, medicament
Spray processing volume increase 8.16% averagely than clear water control.Wherein recommended ratio, i.e. " compound amino acid 300mg/L+ nanometer titanium dioxide
It is 659.8 kilograms that silicon 80mg/L+ dispersing agent 300mg/L " confection, which handles per mu yield, and volume increase 10.21% is compareed with clear water.
It can be seen that under this experimental condition, spray different ratio plant growth conditioner can mitigate to a certain degree it is low
The injury that temperature generates rice seedling, and dramatically increase rice yield.
Finally it should be noted that：The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention,
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used
To modify to technical solution documented by previous embodiment or equivalent replacement of some of the technical features.It is all
Within the spirit and principles in the present invention, any modification, equivalent replacement, improvement and so on should be included in protection of the present invention
Within the scope of.
