There are many irrigation methods for fertilization of fertile soil, but the basic features are irrigation of pipeline systems under pressurized conditions. Small tube outflow, sprinkler irrigation, micro sprinkler irrigation, drip irrigation, seepage irrigation and other methods can be used. They are contrary to flooding and have the characteristics of precision irrigation. Fertilizer types can be selected from liquid or solid, but they are required to be water-soluble and contain very little impurities. Generally, granular compound fertilizer should not be used. If organic liquid fertilizer such as biogas slurry or fulvic acid is used, it should be filtered beforehand to avoid clogging. pipeline. It can be seen that the irrigation and fertilization system requires supporting equipment such as pumps, pipelines, fertilizer pools, fertilizer tanks and fertilizer machines. Take drip fertigation as an example: the water and fertilizer required for the current growth stage of the crop are transported to the root of the crop through a drip irrigation pipeline. Due to the quantitative, regular and accurate supply of water and fertilizer, the technology has the characteristics of water saving, fertilizer saving, labor saving, high yield and high quality. In short, the main features of fertigation are uniform fertilization, small quantities and timely supply. It is required to be differentiated according to the type of crop and the amount of fertilizer required for different growth periods, and matched with the amount of water to be planted. The volatilization loss of the ammonium and urea nitrogen fertilizers on the surface is avoided. This is very important, even if it is difficult to completely avoid the loss of volatilization. Therefore, fertigation and fertilization not only saves nitrogen fertilizer but also contributes to environmental protection, and the utilization rate of fertilizer is greatly improved. It will be widely adopted in the development of intensive agricultural production. Finally, we must remind that the key technology of fertigation is to grasp the principle of timely and proper supply of water and fertilizer, based on the time and space law of the nutritional needs of the target crops, and determine the appropriate fertilization period and fertilization amount.
