粤糖93-159播种密度和施肥水平的研究

Study on the Planting Density and Fertilization Ratio for New Sugarcane Variety Yuetang93-159

设置不同播种量和不同施肥水平的田间生产试验研究了新品种粤糖93-159相适应的高产高糖综合栽培技术,结果表明:粤糖93-159播种量以42000-46500段双芽苗/hm2为佳,能获得较高的蔗产量和糖产量;施肥量以配施尿素750 kg/hm2、过磷酸钙1500kg/hm2和氯化钾450kg/hm2较好,能达到增产增糖增收的目的。

Field experiment with different planting densities and fertilization ratios for Yuetang 93-159, an extremely early maturing and high sucrose content variety, was conducted. Results showed that planting density with 42000-46500 2-buded seed cane/h got higher yields both in cane and sugar. Fertilization ratio of 750 kg/h urea, 1500 kg/h calcium superphoshate and 450 kg/h potassium chloride was better than other ratios, getting higher cane and sugar yields and economic benefit.
