Sea rice soil alkalinity concentration adjusting system and method

Abstract

The invention discloses a sea rice soil alkalinity concentration adjusting system and method.The system comprises a detection adjusting unit and an irrigation unit, and the detection adjusting unit comprises a detection module and a background control module; the detection module comprises two groups of pH value detectors used for detecting the alkaline concentration, a temperature detector used for detecting the air temperature and a wind power detector used for detecting wind power, and the two groups of pH value detectors are respectively mounted below the roots of sea rice and the roots of weeds; the background control module is in signal connection with the detection module; the irrigation unit comprises a fresh water irrigation mechanism and a seawater irrigation mechanism; the background control module is in signal connection with the switch modules of the fresh water irrigation mechanism and the seawater irrigation mechanism. The alkaline concentration can be adjusted in advance in real time according to the surrounding environment, so that the alkaline concentration of the roots of the sea rice is within a proper concentration range, the growth of the sea rice is greatly promoted, and the yield is increased.

Description

technical field [0001] The invention relates to a system and method for adjusting soil alkaline concentration, in particular to a system and method for adjusting seawater rice soil alkaline concentration. Background technique [0002] Rice is one of the most important food crops in the world, providing food for more than half of the world's population. After two "green revolutions", the increase in rice yield has entered a bottleneck period, so expanding the area of ​​rice planting has become an important means to ensure food security. Among them, good land resources have been fully tapped, so the development and utilization of saline-alkali land and other low-yield fields will greatly alleviate the development bottleneck problem caused by the current limited red line of cultivated land. [0003] Rice has become a pioneer crop for the improvement and utilization of saline-alkali land due to its special cultivation method, but the salt-tolerant ability of existing saline-alk...

AI Technical Summary

Problems solved by technology

[0003] Rice has become a pioneer crop for the improvement and utilization of saline-alkali land due to its special cultivation method, but the salt-tolerant ability of existing saline-alkali-tolerant rice varieties is still low (less than 3‰ salinity), which is far from meeting the needs of moderate and severe saline-alkali land. The need for improved utilization

In addition, the existing cultivation of saline-alkali land mainly uses a large amount of fresh water to wash salt and press alkali. The cost of improvement is too high, and it will be less feasible in the future when water resources become more and more precious.
