Vegetable high-temperature stress regulation and control mixture and application method thereof

Abstract

The invention provides a vegetable high-temperature stress regulation and control mixture which comprises the following raw material components in percentage by weight: 0.05-0.15% of salicylic acid, 0.02%-0.05% of brassinolide; 0.3%-0.5% of urea; 0.05%-0.1% of gamma-aminobutyric acid; 0.3%-0.5% of glucose; 0.02% to 0.08% of mepiquat chloride; 0.1%-0.5% of potassium dihydrogen phosphate; 0.07%-0.1%of sugar alcohol boron; 0.07%-0.1% of sugar alcohol iron; 0.08%-0.1% of sugar alcohol calcium; 0.1%-0.3% of zinc sulfate heptahydrate (ZnSO<4>*7H<2>O); 0.1% of an agricultural organic silicon spreader; and 97.42%-98.74% of water. When the vegetable high-temperature stress regulation and control mixture prepared by the invention is adopted, the protective enzyme activity can be obviously improved;the content of malondialdehyde (MDA) is reduced to 1.62-1.67 [mu] mol.g <-1 > FW, in addition, the photosynthetic performance of leaves can be improved, the diseases such as element absorption obstacle, high-temperature nutrient deficiency of plants, root aging of vegetables and root activity reduction can be prevented and treated, the malformed fruit rate is reduced, and the effects of increasing the yield and improving the quality of over-summer vegetables are achieved.

Description

technical field [0001] The invention belongs to the field of vegetable high-temperature adversity regulation and control, and in particular relates to a vegetable high-temperature adversity regulation mixture and an application method thereof. Background technique [0002] High temperature stress is an important environmental limiting factor for oversummer vegetables in the north and south. Vegetables, especially cool vegetables, such as scallions, celery, cabbage, Chinese cabbage, etc., will cause fertility disorders under mild to moderate high temperature stress at 30°C to 35°C, and plant damage will be aggravated under severe stress at 38°C. The main manifestations are: under high temperature stress, the metabolism of active oxygen in leaves and other organs is enhanced, the peroxidation of cell lipid membrane is enhanced, the membrane structure is damaged, and the cell function is reduced; it causes varying degrees of damage to the vegetable photosynthetic system, leadin...

AI Technical Summary

Problems solved by technology

[0010] 1) The existing technology cannot effectively overcome the imbalance of active oxygen metabolism in plants and the imbalance of cell osmotic regulation under high temperature;

[0011] 2) It also fails to solve the damage caused by high temperature adversity to the plant photosynthetic system, resulting in element absorption disorders, high temperature deficiency of plants, aging of vegetable roots, and decline in root vitality;

[0012] 3) There are also problems of abnormal flower bud differentiation under high temperature, decreased pollen viability, poor insemination, and fruit deformity;
