Description
Technical field
The present invention relates to technical field of agricultural fertilizers, relate in particular to a kind of organic-inorganic compound fertilizer of the SOD of interpolation stand-in, and its production method.
Background technology
Organic-inorganic compound fertilizer is a kind of new-type fertilizer, and it integrates the advantage of fertilizer and composite fertilizer, can better the plant growth coordinating environment, and improve the plant nutrition structure and form, effectively improve crop quality.How farthest to improve Plant SOD Activity, enhancing plants antisenescence, anti-adversity ability are the emphasis of fertilizer effect research.
SOD is a kind of active substance that comes from life entity, can eliminate the objectionable impurities that organism produces in metabolic processes.Under normal circumstances, vegetable cell exists the generation of active oxygen and removes two processes.SOD plays a role under temperature stress as a kind of membrane protective enzyme, and environment stress can promote active oxygen to produce, damage film system.And SOD is a kind of important free radical scavenging enzyme, but the Scavenger of ROS free radical, thus prevent the murder by poisoning of free radical, they are called the protective enzyme system for this reason.Some scholars think, SOD with plant cold-resistant, drought-resistant ability is closely related, injury symptom evening appears in the blade strong resistance that SOD content is high.Studies show that SOD can adapt to and coerces and produce respective change, thereby regulates cellular metabolism, with the opposing environment stress.
It is large that SOD has a molecular weight, and the transformation period is short, easily loses activity, and be difficult for passing the shortcomings such as cytolemma, so the application of SOD is restricted.For this reason, some scholars small molecules title complex synthetic and that characterized the metal ions such as a series of cuprics, manganese, iron comes Simulating SOD, it is little that these title complexs (being the SOD stand-in) have a molecular weight, be soluble in polar solvent, more easily see through semi-permeable membranes, long half time has the stronger advantages such as resistibility to temperature, acid-basicity and proteolytic enzyme, can be good at being applied to producing promoting.Temporary transient the discovery has document to be disclosed in fertilizer, especially adds the SOD stand-in in organic and inorganic fertilizer, realizes improvement soil, improves Plant SOD Activity, strengthens plants antisenescence, anti-adversity ability, reduces the rate of fertilizer texts.
