粮改饲背景下江苏沿海滩涂甜高粱青贮饲用探讨

Developing Silage-oriented Sweet Sorghum Industry in Jiangsu Coastal Shoals with the Policy of Converting Grain Fields into Silage-producing Fields

本文阐述了江苏沿海滩涂发展青贮甜高粱产业的必要性和可行性。发展甜高粱是利用盐碱地“粮改饲”、绿色发展的需要。甜高粱适合江苏沿海滩涂种植,其用途广泛,青贮饲喂优势较玉米明显。本文指出了甜高粱青贮方法和优良品质,介绍了甜高粱抗倒伏育种和配套技术,提出了绿色生产技术的深化和集成组装,分析了国内外竞争情况及产业化前景,以期促进和指导当地青贮甜高粱产业发展。

This paper expounds the necessity and feasibility of developing silage-oriented sweet sorghum industry in Jiangsu coastal shoals.The development of sweet sorghum industry is instrumental in using saline-alkali land to produce silage instead of grain,and facilitates green development.Sweet sorghum is suitable for planting in tidal flats and has many uses.When used as silage for feeding livestock,sweet sorghum has obvious advantages over maize.This paper also elaborates the methods of ensiling sweet sorghum and describes its fine qualities.Moreover,this paper introduces the breeding of sweet sorghum varieties with lodging resistance,supporting cultivation technology,and improved and integrated green production technologies.Finally,this paper analyzes the competitive situation and prospect of industrializing silage-oriented sweet sorghum production domestically and internationally in order to promote and guide its regional development.
