Abstract:

Winter-cultivating Italian ryegrass (Lolium multiflorum Lam.) has become a production and utilization mode of winter fallow paddy. The cultivation mode takes full use of limited farmland resource and increases double-cropping index, which provides a large number of high-quality forge grass to alleviate shortages of winter greenfeed in south rural area. Otherwise, Italian ryegrass improves the quality of soil and the communities of microbe, increases the diversity of natural enemy insects, inhibits farmland weeds number and their seed bank, promotes the growth of rice, and increases rice production. With more and more studies and application, Italian ryegrass cultivation management technology has been mature gradually in South China. Through the analyses of variety selection, sowing method, fertilizer-irrigation management, mowing, usage, and effect on soil and after-crop rice, we aim to fully popularize Italian ryegrass cultivation management technology in winter fallow paddy of South China and provide theoretical direction to sustainable utilization of Italian ryegrass.

Key words: Italian ryegrass, Winter fallow paddy, Cultivation management technology, After-crop rice, Utilization

摘要:

水田冬种意大利黑麦草(Lolium multiflorum Lam.)是近年来形成的冬闲田生产利用模式,不仅可以充分利用有限的土地资源,增加复种指数,生产大量的优质青饲料,缓解南方农区冬季青饲料紧缺问题,而且可以改善稻田土壤的理化性质和微生物生态群落,增加天敌昆虫的多样性,抑制农田杂草数量及其种子库,从而促进后作水稻的生长发育,增加其产量。随着研究和应用的不断深入,南方地区意大利黑麦草的栽培管理技术也日臻成熟。本文从黑麦草品种的选择、播种方法、水肥管理、刈割利用,以及对土壤和后作水稻的影响等方面进行全面分析,旨在为意大利黑麦草在南方冬闲田种植技术的全面推广及黑麦草的可持续利用提供更为系统的理论指导。
