[0003] Active oxygen scavengers such as ascorbic acid, reduced glutathione, tocopherol, sodium benzoate and plant growth regulators such as auxin, gibberellin, cytokinin and abscisic acid have been reported many times in wheat, rice and other crops It has a good effect on scavenging active oxygen, regulating plant growth, and promoting plant rooting and germination. However, the reports of these biochemical agents on corn are still few, or are not comprehensive, or are limited to physiological mechanisms. There are few studies on the production of biochemical agents after water spraying

Abstract
The invention discloses a biochemical preparation for the physiological recovery of waterlogged corn. The biochemical preparation is prepared from ascorbic acid and 6-benzylamino adenine, wherein the weight ratio of ascorbic acid and 6-benzylamino adenine is (50-200) to 1. The biochemical preparation for the physiological recovery of the waterlogged corn, disclosed by the invention, has the advantages that the content of active oxygen in corn leaves can be lowered, the activity of an antioxidation system of the corn leaves is obviously improved, the yield reduction extent of the corn does not reach a remarkable difference level compared with that of non-waterlogged corn, and the yield increase effect is the best compared with that of soaked corn.
Description
technical field [0001] The invention relates to the technical field of crop planting, in particular to a biochemical preparation for physiological recovery of maize after waterlogging. Background technique [0002] Maize seedling waterlogging is an adversity disaster often encountered in corn production in the southern Huanghuaihai corn region. Continuous rainfall or floods cause soil flooding, which often affects the normal growth and development of plants. Different degrees of flooding at the seedling stage of corn may lead to a decrease in yield. After the corn seedlings are flooded, the root activity decreases due to hypoxia, the absorption rate of mineral ions and beneficial trace elements decreases, the aerobic respiration pathway changes to harmful anaerobic respiration, and a large number of harmful substances such as H 2 The accumulation of S, etc. seriously deteriorated the maize rhizosphere environment and affected the growth and development of the root system. ...
