Optimally, the invention provides more optional hypertension treatment schemes, so that the patient can flexibly select a proper hypertension treatment scheme according to the actual situation, therefore, the effect and the efficiency of hypertension diagnosis can be improved.

The invention belongs to the field of crop planting, in particular to a high-efficiency corn cultivation method in saline-alkali land. The high-efficiency corn cultivation method in the saline-alkaliland includes the following specific cultivation steps: soil improvement, flat land preparation and application of base fertilizer, corn sowing and film covering, irrigation and fertilization. The method achieves the aim of improving corn emergence rate, seedling preservation rate, water and fertilizer utilization efficiency and further improving corn yield by improving the corn planting method and optimizing the irrigation and fertilization system, breaks through the technical bottleneck of difficult corn planting and improvement in saline-alkali land in low-lying areas, and can play a technical supporting role in efficient improvement and utilization of saline-alkali land and improvement of ecological environment. On the one hand, ridge film furrow planting can effectively reduce the evaporation and consumption of soil moisture, and thus water collection and moisture preservation are favorable, so that crop yield and water use efficiency are improved; on the other hand, the utilization of groundwater can be further promoted, the groundwater level is lowered, and the phenomenon of soil salinization is reduced.
