Control device for irrigating Tie Guanyin tea plant

Abstract

The present invention relates to an irrigation control device of Tieguanyin tea trees, characterized in that soil moisture sensors distributed in each irrigation division are used for detecting soil signals (analog quantity) in a real-time manner, the soil signals (analog quantity) are input into a control system after being converted into digital signals by an analog-to-digital converter, a control subsystem is an integrated control system which takes a single chip microcomputer as a core and starts or stops the control device in accordance with the preset control parameters to determine the irrigation time and amount; when the water potential of the soil decreases to minus 0.6 plus or minus 0.1MPa, a control signal for irrigation is output and the water irrigation amount is controlled to be 11.5-12.6m<3> per mu at one time. The control device provided by invention is particularly beneficial to cause the water irrigation to be more uniform and guarantee water need for growth of the tea trees during a dry season and microenvironment adjustment, and improves the quality and yield of tea leaves.

Description

technical field [0001] This project involves the cultivation of Tieguanyin tea tree and the control device to ensure the optimization of water irrigation during the production process. Background technique [0002] Tea is the most widely distributed economic crop in Fujian Province. In 2006, the province's total tea output, annual export volume and tea garden area ranked first, second and third in the country respectively. However, due to the uneven temporal and spatial distribution of rainfall in Fujian Province, regional and seasonal droughts and water shortages are very serious, and in recent years it has spread and aggravated. For example, during the period from late June to early August in 2003 and from mid-September to mid-November in 2006, there were continuous high-temperature and dry weather in Fujian Province, which caused extensive damage to tea gardens in the province. The frequent continuous drought has seriously restricted the high quality and high yield of t...

AI Technical Summary

Problems solved by technology

[0003] In recent years, although water conservancy departments and tea production enterprises have built some rainwater storage facilities, due to the lack of scientific irrigation technology, the supply of "key water" for the growth of tea trees is mainly based on experience, and flood irrigation is often used. Blindly watering from time to time, not paying attention to water conservation and water conservation, resulting in severe disasters in times of greater drought

In addition, some ecological tea gardens and organic tea gardens have built standardized rainwater storage and irrigation facilities, but they are still manual empirical control models with low technology integration.
