Sowing Date Research on ‘Emma Potato 1’ in Rikaze

【目的】为探索艾玛土豆1号适宜本地区的种植时间。【方法】以日喀则市农业科学研究所艾玛土豆1号脱毒一级种薯为试验材料,探究不同播期对该品种产量和主要性状的影响。【结果】不同播期马铃薯产量从高到低依次为:第3播期5月7日(6698.13kg)>第4播期5月17日(2311.16kg)>第2播期4月27日(1438.5kg)>第1播期4月17日(1336.45kg)>第6播期6月6日(1208.16kg)>第5播期5月27日(1026.07kg)>第7播期6月16日(1011.17kg)。【结论】在日喀则市自然条件下,艾玛土豆1号最适播期是第3播期,即5月上旬最适宜。

【Objective】The present paper aimed to explore the suitable planting time of Emma potato 1 in this region.【Method】The experimental material was Emma potato 1, a kind of virus-free potato from the Agricultural Science Research Institute of Rikaze.The different sowing date on grain yield and main traits of the variety of effects were explored.【Result】Test research shows that different sowing date of potato production order from high to low is that the third sowing date May 7 ( 6698.13 kg)> The fourth sowing date May 17 ( 2311.16 kg)> The second sowing date April 27( 1438.5 kg)> The first sowing date April 17 ( 1336.45 kg)> The sixth sowing date June 6 ( 1208.16 kg)> The fifth sowing date May 27 ( 1026.07 kg)> The seventh sowing date June 16 ( 1011.17 kg).【Conclusion】This shows that under the natural conditions of Rikaze, the best time for Emma potato 1 is the third sowing date, which shows that Early may would be the best.
