Description

Technical Field

[0001] The invention relates to the field of agricultural planting, and in particular to an irrigation system and a daylily planting method. Background Art

[0002] Daylily is a perennial herb of the Liliaceae family. It has extremely high nutritional value and certain hemostatic, anti-inflammatory, diuretic, stomachic, tranquilizing, and lactogenic effects. Therefore, it is loved by the general public. In particular, Qingyang, Gansu, has a history of thousands of years of cultivation. The local daylily is of high quality and has become one of the mainstay crops in the area. However, since the local soil is prone to compaction, and surface irrigation often aggravates soil compaction and hinders plant growth, local farmers rely on the weather for their livelihood and are unwilling to adopt artificial irrigation. This method relies too much on natural conditions. If it encounters a drought year, it will seriously affect the yield and quality of daylily. Summary of the invention

[0003] The invention provides a day lily planting method, comprising the following steps: S1. Origin selection: Choose a flat plot with loose texture and convenient drainage; S2. Seedling selection: Seedlings should be selected from plants that have been planted for 3-4 years and are vigorous, strong, and free of pests and diseases. Dig out 1 / 3 of the plants on one side of each clump with roots as transplant seedlings; S3. Fixed-distance planting: Daylily should be planted in wide rows, with a row spacing of 50-60cm, a plant spacing of 30-40cm, and a planting depth of 5-10cm; S4. Timely irrigation: timely watering according to soil moisture conditions, the appropriate watering interval is once every 10 days, generally 4-5 times during the bolting and budding stages of the daylily; S5. Pest and disease control: physical control and chemical pesticide control can be adopted; S6. Harvesting: Pick the daylily in time before it blooms, and start withering and primary processing immediately.

[0004] Furthermore, in S4, an underground irrigation system is used to supply irrigation water from underground to avoid soil compaction caused by rapid evaporation after surface irrigation. The underground irrigation system includes a water tank 2, which can store clean water or rainwater, and also includes an underground irrigation water pipe 3. The underground irrigation water pipe 3 is pre-buried underground. A plurality of uneven water outlet holes 6 are distributed on the upper part of the underground irrigation water pipe 3. The water outlet holes 6 can slowly infiltrate the water in the underground irrigation water pipe 3 into the nearby soil.

[0005] The present invention provides an irrigation system and a method for planting day lily, and in particular, an underground irrigation system is used for watering, thereby supplying irrigation water from underground, ensuring the growth needs of the day lily, overcoming the problem of soil compaction caused by surface irrigation, and being able to improve the yield and quality of the day lily, and promoting an increase in income and production for farmers who plant the day lily.

[0007] Example 1 The invention provides a day lily planting method, comprising the following steps: S1. Origin selection: Choose a flat plot with loose texture and convenient drainage; S2. Seedling selection: Seedlings should be selected from plants that have been planted for 3-4 years and are vigorous, strong, and free of pests and diseases. Dig out 1 / 3 of the plants on one side of each clump with roots as transplant seedlings; S3. Fixed-distance planting: Daylily should be planted in wide rows, with a row spacing of 50-60cm, a plant spacing of 30-40cm, and a planting depth of 5-10cm; S4. Timely watering: Drought has a great impact on the growth of daylily. Watering must be done in time according to the soil moisture conditions. The appropriate watering interval is once every 10 days. During the bolting and budding stages of daylily, watering is generally done 3-4 times. S5. Pest and disease control: physical control and chemical agricultural control can be adopted; S6. Harvesting: Pick the daylily in time before it blooms, and start withering and primary processing immediately.

[0008] Furthermore, in S4, an underground irrigation system is used, and the underground irrigation system includes a water tank 2, which can store clean water or rainwater, and also includes an underground irrigation water pipe 3. The underground irrigation water pipe 3 is pre-buried underground. The buried depth of the underground irrigation water pipe 3 is controlled near the root system of the day lily, and the specific buried depth is controlled at 15-30 cm. A plurality of uneven water outlet holes 6 are distributed on the upper part of the underground irrigation water pipe 3. The water outlet holes 6 can slowly infiltrate the water in the underground irrigation water pipe 3 into the nearby soil, and utilize the capillary voids in the soil to absorb water to achieve the purpose of irrigation.

[0009] Furthermore, in S4, the water tank 2 is located higher than the ground surface, and its function is to provide potential energy for irrigation water and increase the permeability of water in the underground irrigation water pipe 3.

[0010] Furthermore, in S4, a water valve 5 is provided in the pipeline at the lower part of the water tank 2 to control the water supply to the underground irrigation water pipe 3.

[0011] Furthermore, in S4, the number of underground irrigation pipes 3 matches the number of rows of day lilies planted, and an irrigation pipe is laid under each row of day lilies.

[0012] Example 2 The difference from Example 1 is that in S4, the irrigation system also includes an above-ground irrigation pipe, which is located on the ground surface near the roots of the daylily. There are uneven water outlet holes distributed around the above-ground irrigation pipe. The water outlet holes of the above-ground irrigation pipe are small holes, and the water outlet is controlled to be dripping or pouring to overcome the phenomenon of soil hardening caused by large-scale irrigation. The diameter of the small holes of the above-ground irrigation pipe is 5-8 mm. During operation, the irrigation water is controlled to flow to the above-ground irrigation pipe or the underground irrigation pipe through multiple water valves 5, and can also enter the underground irrigation pipe and the above-ground irrigation pipe at the same time. The water in the above-ground irrigation pipe wets the soil at the roots of the daylily through the small holes, and the underground irrigation pipe directly moisturizes the underground root system of the daylily, achieving efficient irrigation.

[0013] The above description is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the present invention, with changes in shape or replacement of conventional methods, should be covered within the protection scope of the present invention.
