Description

Technical Field

[0001] The invention relates to the technical field of agricultural planting and watering, and in particular to an adaptive watering system for vegetable greenhouse planting. Background Art

[0002] The vegetable greenhouse is a frame-covered structure with excellent thermal insulation performance. Its appearance allows people to eat off-season vegetables.

[0003] Generally, vegetable greenhouses use a steel structure frame, covered with one or more layers of heat-insulating plastic film to form a closed greenhouse space. The outer film effectively prevents the loss of carbon dioxide produced by the growth of vegetables inside, making the greenhouse have a good heat preservation effect.

[0004] Structurally, vegetable greenhouses mainly include load-bearing walls, structural steel frames, supporting columns, arched roofs and plastic outer films; in terms of supporting facilities, modern greenhouses usually include planting troughs, sprinkler irrigation systems, temperature control systems, auxiliary lighting systems and humidity control systems.

[0005] Among them, the planting trough is set at the bottom of the window or made into a screen shape for planting vegetables; the sprinkler system automatically supplies water in a timely and appropriate amount; the temperature control system includes an exhaust fan, a hot fan, a temperature sensor and a constant temperature system control box to adjust the temperature in time; the auxiliary lighting system includes plant lights and reflectors, which are installed around the planting trough to provide lighting when there is no sunlight, so that the plants can carry out photosynthesis; the humidity control system cooperates with the exhaust fan to adjust the humidity and lower the indoor temperature.

[0006] Specifically speaking, the purpose of irrigation is to ensure that greenhouse vegetables can obtain appropriate and sufficient water in different growth cycles through reasonable watering, so as to promote the healthy growth of vegetable crops and increase crop yields. Therefore, the rationality of the design of the sprinkler irrigation system will directly affect the final vegetable crop yield and quality.

[0007] However, the existing sprinkler irrigation system for vegetable greenhouses is relatively backward, and the watering process requires a lot of manual participation, so that in the process of large-scale promotion and application, the following problems often arise:

[0008] 1. Most existing vegetable greenhouses use water pipe flooding, which cannot achieve rational quantitative watering according to the water requirements of vegetables in different growth cycles.

[0009] 2. During the long-distance transportation and consumption of irrigation water, as the water pressure inside the pipeline changes, the range of irrigation water spraying will also change accordingly, making it difficult to achieve precise watering of vegetables in fixed positions during sprinkler irrigation.

[0010] 3. The watering equipment is large and inconvenient to move, which leads to the problem of limited watering range of sprinkler irrigation.

[0011] 4. In some cases, sprinkler irrigation is combined with fertilization by dissolving soluble fertilizers in irrigation water in a certain ratio to achieve integrated application of water and fertilizer. However, since the fertilizers required by plants at different growth stages are different, the existing devices are often unable to completely discharge the water and fertilizer in the pipeline during the process of integrated water and fertilizer application, which will affect the irrigation and fertilization effects due to residual water and fertilizer.

[0012] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention
