Bonsai automatic irrigating and water-supplying device and applying method thereof

Abstract

The invention relates to a bonsai automatic irrigating and water-supplying device and an applying method thereof, and belongs to the technical field of horticulture irrigation. The method comprises the steps of firstly injecting water into an evaporating dish water supplying device and an evaporating dish separately till the water level reaches an initial water level line and an evaporating dish initial water level line, setting a bonsai water allowable transpiration amount and a water level warning line, and using the evaporating dish to simulate bonsai water dissipation. Under the effect of the atmospheric evaporation power, the water level of the evaporating dish is lowered, the water in bonsai soil is also dissipated and reduced under evaporation and transpiration effects, when the evaporation amount of the evaporating dish reaches the bonsai water allowable transpiration amount, a water pressure sensor detects a signal and transmits the signal to an irrigating valve, the irrigating valve is switched on, so that the water in a bonsai water supplying device flows into a water-injecting sand layer at the bottom of a bonsai flowerpot, and thus automatic irrigating and water-supplying of bonsai plants are achieved. According to the bonsai automatic irrigating and water-supplying device and the applying method thereof, it is unnecessary to specially assign people to maintain the bonsai automatic irrigating and water-supplying device, the air humidity and temperature can be adapted to, the watering time is determined through an evaporation amount, so that the water control amount is more accurate, a large amount of labor is saved, and thus the bonsai automatic irrigating and water-supplying device has a wide application prospect.

Description

technical field [0001] The invention relates to a potted plant automatic irrigation and water supply device and an application method thereof, belonging to the technical field of horticultural irrigation. Background technique [0002] The water-supply potting devices used by various scientific research institutes, schools and horticultural flower markets are exactly to use a simple pot, dress certain soil or substrate, plant to be studied or flowers for viewing and viewing are transplanted in the pot. Water the pot regularly. The water treatment methods of potted test devices used for scientific research are mainly weighing method and soil water stress simulation method. This artificial water control will make the soil wet unevenly and inaccurately, and some soil will always reach saturation after adding water. The water content of the soil varies greatly from place to place, and it also needs to undergo a certain period of dry-wet alternation. Excessive fluctuations in soi...

Problems solved by technology

[0004] The technical problem mainly solved by the present invention: currently, the hydration of potted flowers is taken care of by specially-assigned personnel and watered irregularly, but artificial water control may be affected by factors such as air humidity and temperature, which makes it difficult to control the amount of watering, and The defects of a large amount of manpower and material resources are required for maintenance by a dedicated person, and a potted plant automatic irrigation and water replenishment device is provided. The present invention first injects water into the evaporating dish water replenisher and the evaporating dish, until the water surface reaches the initial water level line and the evaporating dish initial water level line. According to the potted plant The relationship between water consumption and water evaporation in the evaporating pan, set the allowable transpiration of potted water and the water level warning line, and the water lost by evaporation in the evaporating pan is replenished at any time by the evaporating pan water replenisher, and the evaporating pan is used to simulate the water consumption of potted plants. Under the action of evaporation, the water level of the evaporating pan drops, and the water in the potting soil is also reduced by evaporation and transpiration. When the evaporation of the evaporating pan reaches the set pot water permissible transpiration, the water pressure sensor detects a signal, and then The signal line of the sensor is transmitted to the irrigation valve, and the irrigation valve is opened to make the water in the potted plant water replenisher flow into the water injection sand layer at the bottom of the potted plant pot, so as to realize the automatic irrigation and water replenishment of the potted plants
