preparation example Construction

[0025] Based on the fertilizer composition effect of the present invention, the present invention also proposes the preparation method of above-mentioned cold-resistant foliage fertilizer, and method step comprises the following steps:

[0026] S10, according to the compatibility of above-mentioned cold-resistant foliage fertilizer, obtain the material of each weight part;

[0027] S20, mixing all the materials obtained in step S10 in a mixer, and reacting at 75-80° C. for 25-35 minutes, and the output after the reaction is the cold-resistant foliar fertilizer of the present invention.

[0028] Adopting the above-mentioned preparation method is simple in process, the components of the material are uniformly dispersed, and the adsorption and nucleophilicity and chelation between the components are sufficient, which is beneficial to mass production; and the prepared cold-resistant foliage fertilizer has a variety of nutrients and nutritional elements that promote growth and metab...

Embodiment 1

[0031] In the present embodiment 1, obtain the raw material of foliage fertilizer according to the following composition ratio (all ingredients are standard commercially available products, obtained by direct purchase): 10 parts of abscisic acid, 10 parts of chitosan, 20 parts of boric acid, potassium carbonate 25 parts, ε-polylysine 5 parts, humic acid 5 parts, methylene succinic acid 10 parts, zinc (nitrate) 1 part, copper (nitrate) 0.2 parts, iron (nitrate) 0.2 parts, manganese (nitrate) 0.2 part, molybdenum (nitrate) 0.1 part, diethylaminoethanol caproate 0.1 part, water 60 parts, edetate disodium 0.1 part.

[0032] Put all the above-mentioned materials into a mixer for mixing. The rotation speed of the mixer is set at 200-300r / min; the temperature is set at 75°C during the mixing process, and the reaction time is 30 minutes;

[0033] Then the sample foliage fertilizer prepared above was used for agrochemical tests to verify the function of the fertilizer, including:

Abstract

The invention discloses a cold-resistant foliar fertilizer and a preparation method thereof, the cold-resistant foliar fertilizer includes 10-15 parts of abscisic acid, 10-20 parts of chitosan, 20-30 parts of boric acid, 25-35 parts of potassium carbonate, 5-15 parts of epsilon-Poly lysine, 5-15 parts of humic acid, 10-30 parts of itaconic acid, 1.7-15 parts of trace elements, 0.1-0.5 part of Hexanoic,2-(diethylamino) ethyl estercitrate, 60-80 parts of water and 0.1-1 part of a chelating agent. The preparation method of the cold-resistant foliar fertilizer comprises the following steps: obtaining raw materials according to the components of the cold resistant foliar fertilizer; and stirring and mixing the obtained raw materials at 75-80 DEG C for 25 to 35min. The cold-resistant foliar fertilizer is directly applied to leaf of crops by spraying, the cold-resistant foliar fertilizer contains the most environmentally-sensitive exogenous hormone abscisic acid, and can quickly adjust the crops to change the metaboilic level to adapt to cold damage environment, and by use of various functional components, effects of low temperature on water in plants can be reduced, nutrients and nutritional components for promoting growth and metabolism can be supplemented, and the metabolic ability of the crops in low temperature environment can be maintained stably.

Description

technical field [0001] The invention relates to the technical field of compound fertilizer preparation, in particular to a cold-resistant foliar fertilizer containing exogenous abscisic acid and a preparation method thereof. Background technique [0002] Chilling injury is a frequent global natural disaster. In agricultural production, temperature is a necessary condition for plant growth and the main limiting factor for the natural geographical distribution of plants. Planted agricultural or commercial crops can only grow and reproduce normally within a certain temperature range. For example, many plants cannot grow in northern or alpine regions because of the limitation of low temperature adversity. When crops suffer from chilling damage, in addition to the changes in external morphology, more importantly, it will delay the speed of a series of plant physiological activities, and even destroy their physiological functions. Physiological damage includes: cell membrane dama...
