膜下滴灌技术具有节水、排盐、提高棉花品质、增产增效的优势。分析了在此技术条件下棉花的增产机理。为获得持续增产,还需进一步研究改进灌溉制度,加强良繁体系建设,研究膜下滴灌水肥调控技术对棉花群体质量的影响,优化生长环境,提高棉花水肥增产潜力。
Underwater drip irrigation technology has the advantages of saving water and salt, improving cotton quality, increasing yield and improving efficiency. The mechanism of cotton yield increase under this technical condition was analyzed. In order to obtain a sustained increase in production, further research should be done on improving the irrigation system, strengthening the construction of good propagation systems, studying the effects of drip irrigation and fertilizer control techniques on the cotton population quality, optimizing the growth environment and increasing the yield potential of cotton by water and fertilizer.
