为探索甘薯新品种桂粉2号在桂北地区种植的高产优质栽培技术,试验选取了栽植密度和栽插时间两个因素,对甘薯桂粉2号的产量、农艺性状及淀粉含量影响等进行了研究。结果表明,不同栽插时间对甘薯桂粉2号的蔓长、分枝数、结薯数、薯重等主要农艺性状均有显著影响;不同栽植密度下,甘薯桂粉2号的产量水平部分间达极显著差异。在夏季(6月29日)以每亩4 000株的栽植密度种植的甘薯产量最高,达2 822.67 kg,淀粉含量为28.9%。试验结果可为甘薯新品种桂粉2号在本区的大面积推广种植提供理论依据。
In order to explore the high-yield and high-quality cultivation techniques of sweet potato variety Gui-2 which is planted in the north of Guangxi, two factors of planting density and planting time were selected to study the effects of sweet potato Gui-2 on the yield, agronomic characters and starch content Study. The results showed that the different planting time had significant effects on the main agronomic traits of sweet potato powder Gui 2, such as vine length, branch number, tuber number and potato weight. Under different planting densities, Between the very significant differences. The sweet potato planted at a planting density of 4 000 plants per acre in summer (June 29) had the highest yield of 2 822.67 kg and a starch content of 28.9%. The test results may provide a theoretical basis for large-scale popularization and cultivation of a new sweet potato variety Gui powder No. 2 in this area.
