Description
Technical field
The present invention relates to the application of sodium nitroprusside and/or sodium nitroprussiate in crop production reduction is slowed down.
Background technology
Surface ozone (O3) be 1~2km of span ground surface layer O3, except on a small quantity by stratosphere O3To transmission near the ground
Outside, the overwhelming majority is by a small amount of natural source and the nitrogen oxides of a large amount of artificial sources (NOx) and volatile organic matter (Volatile
OrganicCompounds, VOCs), under sunlight irradiation, the secondary pollution through a series of generation of photochemical reactions, master
It reacts and is represented by：VOCs+NOx+hν→O3+ other oxidants.
The ground O of current many countries3Pollution has been able to inhibit a variety of Typical crops growths.European Union uses
AOT40 carrys out the critical value that regulation plant is hurt.AOT40 refers to global radiation 50W/m3The period of 3 months in, daytime O3By when
Mean volume fraction CO3In period more than 40ppb, CO3The sum of with 40ppb differences.CTM modelings show nineteen ninety, China
Eastern provinces AOT40 (the difference summation of value and 40ppb of the 6-8 hours month ozone higher than 40ppb) peak is about
12000~15000ppbh will rise to 34000ppbh to the year two thousand twenty.For crops, critical value is
3000ppb·h.In global many areas, O3It is considered as one of most important air pollutants for influencing plant productivity,
Outstanding feature is to cause plant injury.
O3Mainly entered by stomata in plant, injury is generated to blade first.The O of low concentration3It is unapparent to blade
Influence, but work as O3Concentration increase to a certain extent when, various detrimental effects will be caused to blade, destroy normal structure and
Function causes leaf senile to be accelerated, photosynthetic rate reduction, and Efficient leaf area decreased duration, plant strain growth is slow, plant life
Object amount is reduced.Wheat (Triticum aestivum) is the important cereal crops in China, to O3Pollute it is very sensitive, easily by
To injury, yield reduces.Therefore, how to improve the yield of the crops under the conditions of the ozone pollution and become in agricultural production and urgently solve
A major issue certainly.
