甜高粱茎秆高大,富含糖分,是优良的青贮饲料。榨取茎汁可制取酒精和糖,籽粒可食用及饲用,是一种具有广泛用途的作物。目前,全国已有24个省(市)进行栽培,其中面积最大的是丽欧品种,产量及含糖量均较高。近年我省中、南部地区已开发利用,发展较快,但辽北地区生育期短,直接引种晚熟品种难以成功,为此我们采用了覆膜技术,在低温多雨的条件下,丽欧品种能正常成熟,从而为辽北地区开发利用甜高粱闯出了一条新路。材料与方法1985～1986年在铁岭县农业技术推广中心进行甜高粱覆膜与露地栽培试验,采用大区对 Sweet sorghum stalks tall, rich in sugar, is an excellent silage. Squeeze stem juice can be made of alcohol and sugar, edible grain and feed, is a widely used crops. At present, 24 provinces (cities) have been cultivated nationwide, of which the largest is Leo, with a high yield and sugar content. In recent years, the province has developed in the southern region, the development of faster, but the short growing season in northern Liaoning, the direct introduction of late-maturing varieties difficult to succeed, for which we use the film technology, in the cold and rainy conditions, Normal maturity, thus for the development and utilization of northern Liaoning sweet sorghum break a new path. Materials and methods 1985 ~ 1986 in Tieling County Agricultural Technology Promotion Center sweet sorghum mulching and open field cultivation experiment, the use of large area pairs
