Irrigation Management in Rice - SpringerLink
2022年4月10日 · Irrigation water can be managed in either puddled transplanted rice or aerobic rice cultures (dry DSR, wet DSR, AWD) with a focus on reducing the water use, irrigation water need, improving water productivity, and making efficient use of available water.
Water Management for Sustainable Irrigation in Rice
2023年5月31日 · Although experiments on rice production under micro-irrigation systems (drip irrigation and sprinkler systems) are promising, traditional surface irrigation with continuous flooding practices and significant water consumption remains widely dominant in rice cultivation for a number of reasons [121,122,123].
By utilizing the real coding based accelerating genetic algorithm (RAGA) and multi-dimension DP, a method named RAGA?DP was developed to optimize irrigation system of well irrigated rice under non-sufficient irrigation condition in the Sanjiang Plain.
