Description

A kind of method for improving the anti-water logging stress of corn
Technical field
The invention belongs to proportion of crop planting technical field, it is related to a kind of method for improving the anti-water logging stress of corn.
Background technology
Damage or crop failure caused by waterlogging is the major natural disasters of many countries in the world, with the change of global climate condition, China in recent years Flood scope expand year by year, occurrence frequency improve constantly.Soil moisture can excessively cause root system anoxic, be subject to crop Hypoxia Stress, influences the normal growth development of plant, ultimately results in crop yield and the reduction of quality, causes huge to agricultural production Big loss.
Corn occupies critical role in China's grain security, and because China is influenceed by continental monsoon climate, the summer Seasonal rainfall amount typically constitutes from the 60%-70% of annual the total precipitation, after Maize at Seedling Stage waterflooding, causes root activity to drop due to anoxic Low, the absorptivity of mineral ions and healthy trace elements with household is reduced, and aerobic respiration approach changes into harmful anaerobic respiration, great Liang You Evil material accumulation so that growing for root system is affected, occur root amount reduction, the tip of a root become brown, root system rot etc. phenomenon, And the growth of root system is suppressed and can further result in the destruction of plant hormone in vivo balance and trophic disturbance, blade is there is also The phenomenons such as stomata is closed, transpiration rate declines, photosynthetic rate reduction, showing as leaf emergence rate reduces, leaf chlorosis, wilting, from And adverse effect is brought to corn with high yield stable yields.Therefore, the on going result that flooded stain influences on plant growth, further research are summarized How corn water logging stress is alleviated as problem in the urgent need to address in agricultural production.
At present, it is general in Maize Production that flooded stain injury is made up using remedial measure, recover corn growth, such as patent No. It is " biochemical preparation that physiology recovers after a kind of corn flood stain " of " CN201410318602.1 " using by ascorbic acid and table oil The biochemical preparation of rape lactone compounding, a kind of " life after flood stain for corn of Patent No. " CN201410318603.6 " Manage the biochemical preparation for recovering " biochemical preparation that aminoadenine is compounded is saved using by ascorbic acid and 6-, two patents are equal It is that the physiology of corn after flooded stain recovers, described biochemical preparation can reduce active o content in maize leaf, hence it is evident that improve beautiful Rice blade antioxidation system, effect of increasing production is good compared with submerging treatment, but above-mentioned technology has following both sides defect And deficiency：One is adopted remedial measures only for the corn after flooded stain, and the now existing a certain degree of loss of corn cannot recover, And spray biochemical preparation in the corn field after waterflooding and take time and effort；Two is after corn flood stain is only used in above-mentioned biochemical preparation Physiology recover, composition is single, such as adds fertilizer and trace element, while corn growth is promoted, can further reduce single Solely apply brought labour intensity.Therefore, above-mentioned technology is further improved, with preferably popularization and application aborning.
The content of the invention
It is an object of the invention to solve the defect that above-mentioned prior art is present, there is provided one kind can improve the waterlogging-resistant stain of corn The method of stress, the method mitigates injury of the water logging stress to milpa by seed soaking and two kinds of approach of foliage-spray.This It is External Calcium element and amino-oligosaccharide to invent the seed soaking agent selected, and can improve the resistance to overhead flooding injury of corn, additionally it is possible to excite seed to carry Preceding germination, improves plant resistance against diseases；The foliage-spray medicament of selection includes active oxygen scavenger, plant growth regulator, fertilizer Material and trace element, using cooperatively for this several chemicals, help to remove the active oxygen in milpa, reduce Toxic Matter is accumulated, and adjusts plant strain growth, supplements nutrient and trace element, promotes its restoration ecosystem.
In order to solve the above technical problems, the technical solution adopted by the present invention is as follows：
A kind of method for improving the anti-water logging stress of corn, comprises the following steps：
