Method for preparing crop stress-resistant yield-increasing agent by using medicinal plants

Abstract

The invention relates to the technical field of crop stress-resistant and yield-increasing agents, and provides a method for preparing a crop stress-resistant and yield-increasing agent by using a medicinal plant, which comprises the following steps of: cutting the medicinal plant serving as a raw material into sections with the length of 3-5cm, soaking in clear water, putting into a vertical digester, adding cooking liquor, slowly heating the vertical digester to 105-110 DEG C within 1.5-2 hours, keeping the temperature for 1-2 hours, and cooling to room temperature to obtain the crop stress-resistant and yield-increasing agent. And continuously and rapidly heating to 130-150 DEG C, keeping the temperature for 3-4 hours, deflating, reducing the pressure, opening a discharge port, spraying the materials in the pot into a spraying bin, extruding and filtering, and concentrating filtrate to prepare water aqua, powder and granules, thereby obtaining the crop stress-resistant yield-increasing agent. The crop stress-resistant yield-increasing agent is used for seed soaking, seed dressing, root dipping, root irrigation, bottom application and foliage spraying of crops, can enhance the stress resistance of crops, such as drought resistance, salt and alkali resistance, waterlogging resistance, wind resistance, freezing resistance, pest and disease damage resistance and the like, and can also increase the yield.

Description

[0001] The invention provides a method for preparing crop anti-adversity yield-increasing agent by using medicinal plants, which uses medicinal plants as raw materials, cuts them into 3cm-5cm long sections, soaks them with clean water, puts them into a vertical cooking pot, and then adds cooking liquid, Slowly raise the temperature of the vertical steamer to 105°C-110°C within 1.5-2 hours, keep it warm for 1-2 hours, then continue to heat it up rapidly to 130°C-150°C, keep it warm for 3-4 hours, release the air and lower the pressure Open the discharge port, spray the material in the pot into the spray bin, squeeze and filter, and concentrate the filtrate to make water, powder, and granules, that is, the crop anti-stress yield-increasing agent is prepared, which is used for soaking seeds of crops , seed dressing, root dipping, root irrigation, bottom application and foliar spraying can enhance the ability of crops to resist stress, such as drought resistance, salt-alkali resistan...

AI Technical Summary

Problems solved by technology

At present, the methods for obtaining plant extracts include solvent extraction, ultrasonic extraction, microwave extraction and enzyme extraction, but due to the selectivity of solvents, special enzymes, etc. or other conditions, the extraction rate is low and the material composition is simple, so it can be used by crops. Absorbed and utilized functional substances and nutrients cannot be completely cracked and released

[0006] In the application practice of using exogenous substances to improve the ability of crops to increase stress resistance and yield, most of the currently used plant growth regulators and hormones are artificially synthesized, and there are many limitations in the aspect of crop resistance and yield increase. Or use it too late will not produce the desired effect; use frequency and dosage, too low will be ineffective, too high will cause phytotoxicity; use methods and parts are strict; when using in large-scale fields, you should also pay attention to ambient temperature, climate, etc. .....

Due to the complex contradiction between exogenous substances and the adaptability of crops, the use of some substances is often restricted, and even the loss of phytotoxicity is caused.
