Crop physiology resistance inducer and preparation method

Abstract

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.

Description

technical field [0001] The invention belongs to the field of bioengineering, more specifically relates to a crop physiological inducer, and also relates to a preparation method of the crop physiological inducer. The mixture is suitable for various growth stages of various crops such as rice, corn, cotton, rapeseed, melons and flowers, and can effectively induce these crops to acquire physiological resistance under adverse conditions such as low temperature, drought, and strong light. Significantly improve the stress resistance of crops, ensure the stable and high yield of these crops, and avoid soil deterioration and environmental pollution. Background technique [0002] China is one of the countries with the most severe natural disasters in the world. There are many types of disasters, they are widely distributed, occur frequently, and cause heavy losses. In recent years, it has been one of the most serious periods of natural disasters in Chinese history, with frequent and...

Problems solved by technology

However, due to the existence of traditional chemical substance reactions: 1) Poor stability; 2) Not easily absorbed by plants; 3) The amount of application is not easy to control; 4) It is easy to cause some other side effects and other shortcomings, so it has not been widely used

At present, in practice, the induced resistance system of this crop mainly focuses on the comprehensive effect of biological factors and chemical factors on the induction of crop resistance. Although this method overcomes some of the shortcomings of single chemical factor induction, it has a cost Disadvantages such as high and slow effect

Moreover, this kind of induced resistance is mainly concentrated on theoretical research, and there are only a few applications in the induction of crop disease resistance, and there are few studies and applications on environmental adversities such as crop drought, low temperature, and strong light.
