摘要
为探讨龙薯1号在丘陵山地高产高效栽培技术，2005—2006年对龙薯1号进行了栽培试验，试验采用单因子随机区组排列，重复三次进行。产量对比分析结果显示：种植密度应控制在45500—55500株/hm^2；施夹心肥的效益比施夹边肥高；每公顷应施纯氮120kg、五氧化二磷90kg、氧化钾210kg、硼砂15kg；封垄时喷300kg／hm^2多效唑溶液1次。
This paper aims to research into the high - yielding and high - effective cultivation techniques of Longshu No. 1 in hills and dry areas on the basic of experiment of Longshu No. 1 starting in 2005 and ended in 2006. The experiment is carried out in the approach of single - factor randomized block order for three times and resulted in different yield levels. Through a comparative analysis of the different yield levels, the paper accordingly puts forward some suggestions on cultivating Longshu No. 1 in hills and dry areas： planting density must be controlled in the range of 45,500 - 55,500/ hm^2 ; it is more effective to fertilize in the middle than on the edge; the amount of nitrogen, phosphorus pentoxide, potassium and borax needed for per hectare is 120kg, 90kg, 210kg and 15kg respectively; spray Paclobutrazol for one time with a standard of 300kg/hm^2 when sealing the ridge; lift vine after the rain for one time.
