单粒型甜菜品种及播(栽)期的经济性状试验

在吉林省中、西部地区气候条件下，对单粒型甜菜品种中甜-吉洮单301、吉丹单301、HYB-13及其不同播(栽)期的3个试验点的经济性状试验研究表明：各品种的根产量、含糖率、产糖量等均以在5月5日播种及移栽的表现最佳，达到5％或1％显著水平。品种处理分析结果：吉洮单301(移栽)根产量与产糖量最高，九台、大安、洮南3个点次根产量结果分别分为48227．9kg／hm^2、47264．8kg／hm^2和46493．7kg／hm^2，与其它品种处理呈1％显著水平；对应3个点次，产糖量结果分别为6650．4kg／hm^2、7172．1kg／hm^2和7703．5kg／hm^2，与其它品种处理呈1％显著水平。吉丹单301(直播)含糖率最高，3点次含糖率分别为：16．4％、18．0％和19．3％。

Test of economic character on sugarbeet monogerm variety at transplanting date

The results of the study on the economic character of the experiment of the single seed sugarbeet variety and the planting(transplanting)date in three area in the middle and the west of Jilin province showed.The root yield sugar content and sugar yield of the varieties were best when they were planted(transplanted)on 5th in May,and reached 5 percent or 1 percent striking level.The results of variety treat showed:the root yield and sugar yield of Jitaodan301(transplanting)were the topest of all the varieties.The root yield of three area were (48 227.9)kg/hm~2,(47 264.8)kg/hm~2 and 46 493.7kg/hm~2,reached 1 percent striking level contrasting to the else varieties.The sugar yield in correspendence to the root yield of three area were (6 650.4)kg/hm~2,(7 172.1)kg/hm~2and (7703.5)kg/hm~2.Reached 1 percent striking level contrasting to the else varieties.The sugar content of Jitaodan 301(planting) was the topest of all the varieties the resuts of the three area were (16.4%),(18.0%)and (19.3%).
