Abstract
The present invention provides a kind of method improving the anti-water logging stress of Semen Tritici aestivi, comprises the following steps: (1), soaked seed 24 hours with the salicylic acid of 200mg/L before planting by wheat seed；(2), after the wheat seed plantation length soaked seed is emerged, with the salicylic acid of 200mg/L, seedling is sprayed.Utilizing wheat seed and seedling thereof that the inventive method processed, its upgrowth situation is less than suffering the infringement after floods.
Description
Technical field
The present invention relates to agricultural production, particularly relate to a kind of method improving the anti-water logging stress of Semen Tritici aestivi.
Background technology
Semen Tritici aestivi is originated as the main food of the mankind, and it has very important effect, but, in business
During peasant person plants Semen Tritici aestivi, owing to the factor that can not resist of weather causes Semen Tritici aestivi appearance water stain
Time, Semen Tritici aestivi yield then will plummet even that No kernels or seeds are gathered, as in a year of scarcity, has a strong impact on the income of peasant.
Summary of the invention
It is an object of the invention to solve the defect that above-mentioned prior art exists, it is provided that one can improve
The method of the anti-water logging stress of Semen Tritici aestivi.
A kind of method improving the anti-water logging stress of Semen Tritici aestivi, comprises the following steps:
(1), wheat seed is soaked seed 24 hours with the salicylic acid of 200mg/L before planting；
(2), after the wheat seed plantation length soaked seed is emerged, with the salicylic acid of 200mg/L to children
Seedling sprays.
Further, the method improving the anti-water logging stress of Semen Tritici aestivi as above, step 2 also includes often
The salicylic acid of a 200mg/L was sprayed every two day morning.
The method of the anti-water logging stress of Semen Tritici aestivi that the present invention provides, makes Semen Tritici aestivi when suffering water stain, can drop
The low water stain infringement to Semen Tritici aestivi, improves Semen Tritici aestivi yield then.
Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below technology in the present invention
Scheme is clearly and completely described, it is clear that described embodiment is that a part of the present invention is implemented
Example rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained under not making creative work premise, broadly falls into the present invention and protects
The scope protected.
1, the yield experiment of Semen Tritici aestivi under salicylic acid (SA) improves field waterlogged conditions
1.1 test procedures:
Test set normal water supply positive control (CK), accumulated water process and do not execute SA negative control (-CK) and
The SA process of 200mg/L, every kind processes 3 times and repeats.Each plot area is 12.5 square metres.
Accumulated water processes to field just occurs that open fire, the dusk after accumulated water processes 24 hours spray SA, often
Within three days, spray once.Normal water management is recovered, species test after results after accumulated water processes 15 days.
1.2 result of the tests are shown in Table 1
Table 1
| Process | Cell production (kg) | Per mu yield (kg) |
| CK | 4.51 | 240.53 |
| -CK | 1.90 | 101.23 |
| SA | 2.99 | 159.91 |
Being found by table 1, the yield of normal water supply group is apparently higher than negative control and the Semen Tritici aestivi of SA process group
Yield, but the yield of negative control Semen Tritici aestivi, therefore, SA pair it is higher than through the wheat yield of SA process group
Semen Tritici aestivi has the performance of waterlogging-resistant stain.
In order to the most pre-prevention waterlogging stain infringement to Semen Tritici aestivi, therefore, the present invention carries by the following means
The performance of the waterlogging-resistant stain of high Semen Tritici aestivi.
First, wheat seed is soaked seed 24 hours with the salicylic acid of 200mg/L before planting；
Secondly, after the wheat seed plantation length soaked seed is emerged, with the salicylic acid of 200mg/L to children
Seedling sprays, and the frequency sprayed is to spray the salicylic acid of a 200mg/L every three days morning.
Experimental program:
1.SA improves the Flood resistance experiment of Germinating Wheat
1.1 test procedures:
The SA of wheat seed 200mg/L soaks seed 24 hours, arranges Seed soaking as negative simultaneously
Comparison (-CK).Then normal accelerating germination is to submerging treatment (tap water did not had seed) after showing money or valuables one carries unintentionally, and floods
Water moves to normal growth one week in Nutrition Soil after processing 36 hours, carries out the survey of various index after one week
Amount.Test sets normal accelerating germination, not by flooding stress for positive control (CK).Test sets 3 weights
Multiple.
1.2 result of the tests are shown in Table 2:
Table 2
Conclusion: the wheat seed through salicylic acid seed soaking occurs waterlogging in germination process, and it is raw
Long situation is better than the wheat seed not processed.
2.SA improves the Flood resistance experiment of Wheat Seedling
2.1 test procedures:
Indoor pot, cultivation temperature is: controls temperature daytime at 25 DEG C, controls temperature night/17
℃.When seedling grew to for 31 heart stage of leaf, the culturing pot grown seedlings is packed in Plastic Drum, simultaneously
Water to soil surface and have open fire.Spraying with the SA of 200mg/L respectively after 24 hours, comparison is steamed
Distilled water sprays.Spray once (within the most every three days, processing once) every three days morning, note moisturizing simultaneously,
With the seedling of normal growth as positive control (CK), process with accumulated water and seedling that unused SA processes is
Negative control (-CK).Process the previous day (0d) respectively at flood stain, flood stain process after 5,10,15d
Measure a defence enzyme activity processed (to include: peroxidase, POD；Catalase, CAT；
Superoxide dismutase, SOD) and chlorophyll content, test sets 3 repetitions.Flood stain processes 15
After it, end processes, and takes pictures.
2.2 result of the tests, are shown in Table 3 and table 4.
Table 3SA processes the impact of wheat seedling Activity of Protective Enzymes under water logging stress
Table 4SA processes the impact of chlorophyll content in wheat seedling body under water logging stress
By table 3 and table 4 it can be seen that use SA periodically Wheat Seedling to be sprayed, Ke Yiti
The waterlogging-resistant stain ability of high Semen Tritici aestivi.
Last it is noted that above example is only in order to illustrate technical scheme, rather than to it
Limit；Although the present invention being described in detail with reference to previous embodiment, the ordinary skill of this area
Personnel it is understood that the technical scheme described in foregoing embodiments still can be modified by it, or
Person carries out equivalent to wherein portion of techniques feature；And these amendments or replacement, do not make corresponding skill
The essence of art scheme departs from the spirit and scope of various embodiments of the present invention technical scheme.
