Problems solved by technology

Under adversity, the level of MG in plant cells rises rapidly, which becomes the response signal of plants to environmental stress, and is closely related to stress resistance. However, no one has conducted systematic research in fruit trees to excavate new organic growth regulating substances and carry out research on drought resistance regulation technology. Helps to maintain higher plant yield under drought conditions, and has important theoretical and practical significance for saving water resources and improving the ecological environment

specific Embodiment 1

[0032] First 2% methylglyoxal, 15% trace element chelate, 10% fulvic acid and 25% water solvent are fully mixed in the agitator, and the mixed solution is placed in the spraying device, and then under the drought stress of chestnut seedlings, Use a spraying device to spray mixed solvents such as methylglyoxal on the leaves of chestnuts. After spraying the leaves of chestnuts, carry out superoxide dismutase (SOD), peroxidase (POD), and peroxidase on leaves of chestnut seedlings.

specific Embodiment 2

[0034] First 4% methylglyoxal, 20% trace element chelate, 15% fulvic acid and 30% water solvent are fully mixed in the agitator, and the mixed solution is placed in the spraying device, and then under the drought stress of chestnut seedlings , using a spraying device to spray mixed solvents such as methylglyoxal on the leaves of chestnuts, and after the spraying of leaves of chestnuts, carry out superoxide dismutase (SOD), peroxidase (POD), and Catalase (CAT), ascorbate peroxidase (APX) and other antioxidant enzyme activities and malondialdehyde (MDA), H2O2 and other antioxidant substances content detection, and then malate dehydrogenase (MDH), phosphofructokinase (PFK) and glucose-6-phosphate dehydrogenase (G-6-PDH) and other enzyme activities related to respiratory metabolism, the final detected proline content is higher, and the activity of enzymes related to respiratory metabolism is higher, so there is no need to carry out the test again Spraying chestnut foliage; if the ...

specific Embodiment 3

[0035] Specific embodiment 3 at first 6% methylglyoxal, 35 trace element chelates, 20% fulvic acid and 40% water solvent are as fully mixed in agitator, mixed solution is as in spraying device, then in Chinese chestnut seedling Under drought stress, use a spraying device to spray mixed solvents such as methylglyoxal on the leaves of chestnuts. After spraying the leaves of chestnuts, perform superoxide dismutase (SOD) and peroxidase (POD) on leaves of chestnut seedlings. ), catalase (CAT), ascorbate peroxidase (APX) and other antioxidant enzyme activities and malondialdehyde (MDA), H2O2 and other antioxidant substances content detection, and then malate dehydrogenase (MDH), Detection of the activity of enzymes related to respiratory metabolism such as phosphofructokinase (PFK) and glucose-6-phosphate dehydrogenase (G-6-PDH). There is no need to spray the chestnut foliage again; if the proline content in the final test is low and the activity of enzymes related to respiratory me...

Abstract

The invention discloses a method for improving the drought resistance of castanea mollissima. The method comprises the following steps of sufficiently mixing 2-6% of methylglyoxal, 15-35% of a trace element chelate, 10-20% of fulvic acid and 25-40% of a water solvent in a stirrer, placing a mixed solution in a spraying device, and spraying a mixed solvent such as the methylglyoxal to the leaf surface of the castanea mollissima by the spraying device under the drought stress of castanea mollissima seedlings, so that the mixed solvent is absorbed by the leaf surface of the castanea mollissima, and the castanea mollissima has an excellent anti-drought characteristic. The methylglyoxal is used for regulating various physiological processes such as leaf seedling germination and plant growth anddevelopment of the castanea mollissima and formation of stress tolerance, so that the castanea mollissima has good drought resistance; the method is simple in process; and castanea mollissima products which are high in vitality and low in irrigation cost can be created.

Description

technical field [0001] The invention relates to a method for improving fruit performance through an auxiliary agent, in particular to a method for improving the drought-resistant performance of chestnut. Background technique [0002] Plant growth is inseparable from water. Water shortage often affects plant growth and development, slows down plant nutrient storage and protein synthesis, and reduces yield. In the current global drought environment, the study of plant drought tolerance has become more and more important. . Chestnut (Castanea mollissima) is native to my country and is one of the earliest fruit tree species cultivated in China. It is also an important economic forest tree species. It can not only be used as food, wood, medicinal materials, etc., but also conserve water, prevent soil erosion, and maintain biodiversity. Chestnut can be developed in arid and barren sandy mountainous areas, which has the function of ecological protection. However, the contradiction ...
