Description

Technical Field

[0001] The invention specifically relates to the technical field of plant planting, and in particular to a plant root irrigation device for preventing and controlling diseases and insect pests. Background Art

[0002] Irrigation means watering the land. The principle of irrigation is that the amount of irrigation, the number of irrigations and the time should be determined according to the water requirements of the medicinal plants, the growth stage, the climate and the soil conditions. Irrigation should be timely, appropriate and reasonable. The main types of irrigation include irrigation before sowing, irrigation for seedling promotion, irrigation during the growth period and irrigation in winter.

[0003] Technical measures to supplement the water needed by crops. In order to ensure the normal growth of crops and obtain high and stable yields, crops must be supplied with sufficient water. Under natural conditions, the water requirements of crops are often not met due to insufficient precipitation or uneven distribution. Therefore, artificial irrigation must be carried out to make up for the lack of natural rainfall.

[0004] Traditional irrigation uses surface drip irrigation or infiltration irrigation. Traditional irrigation methods are shallow, so the plant roots are not deep enough. Under natural conditions, they cannot absorb enough nutrients and water to support the growth of large plants. Therefore, the yield of plants with shallow roots is usually small. In addition, plants have poor resistance to cold, dryness, and spring ecological restoration. Especially in the north, the temperature is low, the wind is strong, and the dryness in winter. The shallow roots of plants are usually easily frostbitten. In spring, they cannot absorb and transport water and nutrients in time, causing the plants to weaken or even die. Therefore, traditional drip irrigation can only supply water and fertilizer on the surface, which cannot meet the normal water and fertilizer needs of the root system. Summary of the invention
