Description
Technical Field
The invention belongs to the technical field of corn cultivation, and particularly relates to a conditioner for improving high-temperature resistance of corn, and a preparation method and application thereof.
Background
Corn is one of the most important food crops in China and plays a very important role in national economy. In recent years, along with the frequent occurrence of adverse climates such as high and low temperature, short illumination and the like in the corn production process all over the country, huge loss is brought to the corn production. The high and low corn yield is related to food safety, breeding industry development and national civilization of China and even the world, so that the improvement of the high temperature resistance of the corn and the reduction of the influence of natural disasters on the growth and development of the corn and the yield and quality are necessary.
The corn is often subjected to various natural disasters in the growth and development process, and the high-temperature drought has great influence on the yield and the quality of the corn in the middle and later growth stages of the corn. The high temperature hazard in the middle and later stages of the corn generally means that the pollen and the filaments of the corn are subjected to high temperature above the highest critical temperature of development, so that the corn cannot normally fruit and the production is seriously reduced.
At present, the common prevention measures for the high temperature damage in the middle and later periods of the corn at home and abroad mainly adopt the measures of heat-resistant varieties, seeding in time selection to avoid the high temperature, scientific irrigation, scientific fertilization and the like. But fewer heat-resistant varieties can be selected in production, and the varieties are generally low in yield, so that the number of applications in production is small; the measures for avoiding high temperature during the selected sowing are influenced by the crop rotation, and the regulation and control scope is not too much. High-temperature drought is often sudden, and once high-temperature damage is generated, the intervention is carried out by using conventional cultivation measures, so that the effect is basically ineffective. Therefore, the effect of general agricultural cultivation measures on the high temperature damage in the middle and later periods of the corn is not good, and the aims of disaster prevention and reduction cannot be remarkably fulfilled. According to the theory of the chemotherapy of plant climate disorder, the plant physiological active substances and nutrient elements are utilized to activate the activity of enzymes in the corn body, regulate and control the corn plant type, improve the canopy structure, increase the aerial root of the corn, enhance the root activity, improve the transpiration heat dissipation efficiency and the lodging resistance, enhance the high temperature resistance of pollen (silk) and improve the activity, can obviously reduce the corn tip and seed setting rate which are influenced by high temperature and reduce the yield caused by the reduction of hundred-grain weight, and particularly has extremely obvious yield increase effect when no high temperature occurs. Therefore, the method for improving the high temperature resistance of the corn by utilizing the plant physiological active substances and the nutrient elements is an effective new technical way for scientifically preventing and relieving the high temperature hazard of the corn in the middle and later periods.
At present, no product capable of effectively improving the high-temperature resistance of the corn exists.
