The invention discloses a
crop physiology resistance
inducer and a preparation method. The
crop physiology resistance
inducer is prepared from nano SiO2, nano CaCO3, heteroauxin,
abscisic acid,
humic acid,
monopotassium phosphate and
distilled water according to certain ratio. The preparation method comprises the following steps: (1) taking nano SiO2, nano CaCO3, heteroauxin,
abscisic acid,
humic acid,
monopotassium phosphate and
distilled water for standby application; (2) weighing the raw materials respectively according to the
mass percent of the preparation amount, dissolving nano SiO2 and nano CaCO3 with ethyl
alcohol respectively, mixing the solutions, after certain period of time, adding heteroauxin and
abscisic acid, adding
distilled water for
dissolution, uniformly stirring, performing ultrasonic treatment, adding
humic acid and
monopotassium phosphate, adjusting the pH value with
hydrochloric acid, and adding distilled water for constant volume to obtain the
crop physiology resistance
inducer. According to the invention, the formula is reasonable, the application is convenient, the resistance of crops to drought, low temperature, hard light and other adverse situations can be effectively induced, and high and stable yield of the crops can be ensured; the preparation method is practical, simple and convenient to operate, stable in ingredient dispersion, ecological and environment-friendly, free of environmental
pollution, and convenient to popularize and apply.
