| 摘 要： | 自块茎膨大始期起,对不同生育期的马铃薯植株采样分部位进行测量研究。研究表明,干物质是构成马铃薯产量形成的物质基础,干物质的分配方向是决定块茎产量高低的重要因素。克新19号的块茎干物质分配一开始即呈直线增长,迅速达到一个较高水平。叶面积在4304.70～5114.35cm2时块茎干物质积累速度最快,保持在每天每株4.837～5.637g,并且持续时间长。

| Abstract: | The test studied the fresh weight of the different part of the whole plant every week from the stage of tuber-expanding. The results showed that：dry matter was a basis for yield formation and the direction of dry matter distribution was a significant factor to determine the tuber yield. When the tuber appeared,the distribution of dry matter in tuber had a straight increasing in the first two weeks. When the leaf area is between 4304.70 cm2 and 5114.35cm2,the speed of the accumulation of dry matter kept from 4.837 to 5.637grams per hill per day,and continued for a long days. |
