| 摘要: |
| 1997年春季在广西大化县七百·乡·石屯和北景乡的万塘、百洞进行日本马铃薯品种:97001、97002、97003引种试验。结果是3个品种在3个不同生态条件下均能成活,无病虫害发生,都有开花习性。品种97003平均株高50.3cm,分枝2~3个,比其余2个品种长势好。播种至出苗时间需要25d~27d;营养生长时间:品种97002,27.6d,品种97001,26d,品种97003,24d;生殖生长时间:品种97003,约25.3d,品种97002和品种97001相接近,约22d。在七百·和万塘,单穴结薯个数和单穴薯重是品种97003 > 品种97002 > 品种97001;在百洞点,单穴结薯个数是品种97003 > 品种97001 > 品种97002,单穴薯重是品种97003 > 品种97002 > 品种97001。3个试验点中七百·最适合日本马铃薯生长。 |

| Abstract: |
| The introduction trial of three Japanese potato cultivars 97001,97002 and 97003 was carried out in three different ecological condition areas, Longshitun of Qibailong village,Wantang and Baidong of Beijing village of Dahua county of Guangxi in Spring 1997.The results were as follows:all three cultivars could be alive and didn't occur diseases and insects.The cultivar 97003 showed that the mean plant height was 50.3 cm,the main stem numbers were 2~3 and the growth was better than the other two. The period from sowing to emergence needed 25~27 days.The vegetative period needed 27.6 days,26 days and 24 days,respectively for cultivars 97002,97001 and 97003.Reproductive period needed about 25.3 days for cultivar 97003,about 22 d for cultivars of 97002 and 97001.The tuber numbers per hill and the weight per tuber in Qibailong and Wantang was in the order of 97003 > 97002 > 97001.In Beidong,the tuber number per hill was in the order of 97003 > 97001 > 97002 and the weight per tuber was in the order of 97003 > 97002 > 97001.Qibailong was the most suitable spot to grow Japanese potato among three spots. |
