摘要
以马铃薯早熟品种东农303为试验材料,在长沙地区进行春马铃薯不同播期试验,研究其对春马铃薯的生长、产量及效益的影响。结果表明:(1)长沙春马铃薯不宜过早播种,过早播种容易遭受晚霜危害,产量较低;(2)长沙春马铃薯的适宜播期在12月中旬,此期播种产量较高,效益较好;(3)长沙春马铃薯晚播的产量最高,但效益低,并且延误早稻生产。
The potato early variety Dongnong 303 was taken as experimental material,and the field experiments of spring potato in Changsha were conducted to study the effects of different sowing periods on growth,yield and benefit of spring potato.The results showed that the spring potato is not suitable to sow seeds early in Changsha for it is easy to suffer the late frost harm and lead the low yield;the optimum sowing period of spring potato in Changsha is in the midDecember,when sowing at this time,the yield is high and the benefit is great;if sowing late,the yield of spring potato in Changsha is the highest,but the benefit is the lowest,and it will delay the time of early rice＇s production.
