摘要
为了寻找合适广西冬种免耕栽培的高产马铃薯品种,2009年冬我们首次从青海引进了部分青薯系列马铃薯品种在广西开展了不同种植畦面的大田试验。结果表明,青薯7号与青薯8号出苗均比较快而整齐;青薯8号在现蕾期与成熟期的株高均比较适宜,茎较粗,叶片数较多,具有夺高产的生长优势;同一马铃薯品种小畦种植的株高、茎粗、叶片数、分枝数均大于大畦种植,除青薯8号外,鲜薯产量也以小畦种植处理较高。可见,在免耕马铃薯生产中,应该根据不同马铃薯的品种特性,适宜的安排马铃薯种植方式,以实现免耕马铃薯的高产稳产。
In winter of 2009,some of the Qingshu potato varieties from Qinghai were introduced for the first time and the field experiment of different varieties of the potatoes with no-tillage under different bed widths was carried out in order to search for suitable and high-yielding winter potato varieties of the no-tillage cultivation in Guangxi.The results showed that Qingshu 7 and Qingshu 8 were faster than other potato varieties in the emergence.Qingshu 8 was more vigorous with the high plant height,wide stem and more leaves.For the same varieties,when planted in the narrow bed,it was higher in plant height,wider in stem diameter,and had more leaves and more stem numbers compared with wide bed cultivation.Furthermore,all but Qingshu 8 had a higher yield when planted in the narrow bed.Thus,appropriate cultivation patterns according to different potato varieties for winter potato production should be chosen.
