云光14号为中国云南省农科院选育的优质高产二系杂交籼稻组合。2013年在缅甸姑莱基地设置肥料、密度试验,并进行种植效益比较。结果表明,云光14号在缅甸的生育期缩短,为保证产量,以34.5万丛/hm2的群体量为宜;肥料与产量呈正相关,3个施肥量水平下小区实收产量较不施肥对照均有显著提高,但3个水平间无显著差异;缅甸稻谷收购价格低而肥料成本高,在缅甸进行推广应用时,以少肥即施尿素150 kg/hm2、复合肥300 kg/hm2为宜。
Yun-Guang 14th China Yunnan Academy of Agricultural Sciences breeding high quality and high yield two-line hybrid indica rice combinations. In 2013, a fertilizers and density test was set up at the Gulai site in Burma and the benefits of planting were compared. The results showed that the growth period of Yun-Guang 14 in Burma was shortened. In order to ensure the yield, the population of 345 000 clumps / hm 2 was suitable. Fertilizer and yield were positively correlated. The actual yield of plot-harvest in the three fertilization levels was lower than that of the non-fertilization control However, there was no significant difference among the three levels. Burma’s rice purchase price is low and fertilizer cost is high. When it is applied and popularized in Myanmar, it is preferable to use less fertilizer, ie urea 150 kg / hm2 and compound fertilizer 300 kg / hm2 .
