preparation example Construction

[0037] The invention provides a preparation method of the plant composite anti-stress agent, comprising the following steps:

[0038] (1) Mix manganese and zinc among trace elements with chitin, dissolve the resulting mixture with water at a ratio of 1:1 to 2 by mass, and then mix the obtained mixed wet material with copper, iron and potassium fulvate in sequence , dried to obtain the first mixture;

[0039] (2) organic germanium, sodium nitrophenolate, choline chloride, allantoin and seaweed essence are mixed to obtain the second mixture;

[0040] (4) mixing the first mixture in the step (1), the second mixture in the step (2) and ascorbic acid to obtain a plant composite anti-stress agent.

[0041] The present invention has no special limitation on the mixing method, and the mixing scheme well known in the art can be used.

[0042] The invention provides the application of the plant compound stress resistance agent or the plant compound stress resistance agent prepared by ...

Abstract

The invention provides a plant composite anti-stress agent, and a preparation method and applications thereof, and belongs to the technical field of plant nutrition. The plant composite anti-stress agent comprises, by weight, 0.4 to 0.8 part of organic germanium, 1 to 3 parts of ascorbic acid, 0.5 to 3 parts of compound sodium nitrophenolate, 0.2 to 1 part of choline chloride, 1 to 2 parts of allantoin, 5 to 10 parts of chitosan, 3 to 6 parts of seaweed extract, 0.5 to 1 part of trace element, and 10 to 20 parts of potassium fulvic acid; the trace elements comprise copper, manganese, zinc, andiron at a mass ratio of 0.2-1.5:2-4:7-14:15-25. Synergistic effects of the components of the plant composite anti-stress agent are achieved, so that self protection mechanisms of plants grow at stress environment is started and enhanced, tolerance of plants on stress environment is improved, damage caused by stress environment is reduced, plant stress resistance is improved, and the plant composite anti-stress agent is capable of improving growth, and increasing yield of a plurality of crops at stress environment especially at salination environment.

Description

technical field [0001] The invention belongs to the technical field of plant nutrition, and in particular relates to a compound plant anti-stress agent and its preparation method and application. Background technique [0002] When the plant is in a bad environment, it will automatically activate the stress resistance mechanism to avoid the impact of the external environment on the normal growth of the plant. Adverse environments include drought resistance, salt resistance, waterlogging resistance, wind resistance, frost resistance, and pest and disease resistance. Under natural conditions, due to various reasons such as different geographical locations, climatic conditions, and human activities, various adverse environments have been created, beyond the range that plants can tolerate for normal growth and development, resulting in irreversible damage or even death of plants. [0003] In order to improve plant stress resistance, commonly used methods include the application ...
