Screening of Winter Potato Varieties for Guangxi Under Low Fertilizer
This study took 10 potato varieties in Guangxi as the research object,and compared the agronomic characters of each potato,such as plant height,stem diameter,yield,number of tubers per plant,commercial potato rate and protein content,starch content and other variety char-acters under the condition of conventional fertilization and 20%reduction of fertilization.The plant height,stem diameter,fresh weight above ground and yield of all potato varieties were inhibited under the condition of 20%reduction in fertilization.Among them,Jingshu 6 and Longshu 7 reduced their yields more than 35%,Lishu 6 and 03-3-2 by about 28%,No.12,Guinongshu 1,Yunshu 107 and Huishu 8 by about 15%,and Huishu 16 and Feiwuruita by about 10%.No.12 and Guinongshu 1 had the higher yield under the condition of reducing fertilizer,and were more suitable for planting under the condition of reducing fertilizer in Guangxi.
