Technical measures for supplementing the water needed by crops. In order to ensure the normal growth of crops and obtain high and stable yield, the crops must be supplied with sufficient moisture. Under natural conditions, the water requirement of crops cannot be met due to insufficient precipitation or uneven distribution. Therefore, irrigation must be done manually to compensate for the lack of natural rainfall. Irrigation, namely watering the land with water. The irrigation principle is that the irrigation quantity, the irrigation times and the irrigation time are determined according to the water requirement characteristics, the growth stage, the climate and the soil conditions of the medicinal plants, and the medicinal plants are irrigated in a proper time and in a proper amount and reasonably. The main types of the irrigation include irrigation before sowing, seedling-accelerating irrigation, growth period irrigation, winter irrigation and the like.
