摘要
[目的]探讨昆明地区马铃薯(Solanum tuberosum L.)收后最适宜种植的作物及其最适播期,从而来提高复种指数和土地利用率。[方法]以马铃薯、大豆(Glycine max L.)和荞麦(Fagopyrum esculentum L.)为试验材料,设计3种作物不同播期试验(6月29日、7月19日、8月8日、8月28日、9月17日、10月7日)。[结果]播期对不同作物的生长状况和产量都有明显的影响,大豆和荞麦的产量随播期的延迟呈下降趋势,适时早播有利于其高产,又可避免霜冻的危害;马铃薯的产量随播期的延迟呈先增后减的趋势。昆明地区马铃薯收后种植马铃薯的适宜时期是7月中下旬,在马铃薯收后最适宜种植的是荞麦和大豆,荞麦最迟播种的时间是7月中下旬,大豆最迟播种的时间是6月上旬。[结论]该研究可为昆明地区马铃薯收后作物的实际生产提供理论依据。
[ Objective ] The aim was to discuss the most suitable crops and the sowing time after potato（ Solanum tuberosum L. ） harvest, and to improve multiple cropping index and land utilization rate in Kunming area. [ Method] Six sowing times（06 -29, 07 -19, 08 -08, 08 - 28, 09 - 17, 10 -07 ） of three kinds of crops, potato, soybean（ Glycirte max L. ） , buckwheat（ Fagopyrum esculentum L. ）, were designed to carry out the sowing time test. [ Result] The results showed that sowing time had a significant effects on their growth condition and yield. Soy- bean and buckwheat~ yields significantly decreased with the delay of sowing time, the suitable early sowing not only could gain high yield, but also could avoid the damage of frost; with the sowing time delay, potato＇s yield first increased and then decreased. The suitable sowing time of the potato after potato harvesting was the second and third ten days of July in Kunming, the most suitable crops were buckwheat and soybean, and the latest sowing time of soybean was the second and third ten days of July, and that of soybean was the first ten days of June. [ Conclu- sion] The study provides a theoretical basis for crops actual production after potato harvesting in Kunming.
