采用随机区组试验设计,以龙庆1号和龙盾104为试验材料,研究肥水耦合对寒地水稻产量的影响。结果表明:2个品种的肥料与水分处理间在穗数、结实率、千粒质量及产量上均存在互作关系;龙盾104肥料处理以F3的产量最高,肥水耦合以F3S3的产量最高,显著或极显著高于F3S1、F1S3、F1S1、F1S4、F2S3处理;龙庆稻1号水分处理以S1产量最高,肥水耦合以F3S1最高,显著或极显著高于F3S4、F1S3、F2S3、F1S4、F2S2处理。
Randomized block trial design was used to study the effects of fertilizer and water coupling on the yield of rice in cold region with Longqing 1 and Longdun 104 as experimental materials. The results showed that there was interaction between fertilizer and water treatment in spike number, seed setting rate, grain yield and grain yield of the two cultivars. The yield of F3 in Longdu 104 was the highest, the yield of F3S3 was the highest in fertilizer and water coupling, Significantly higher than that of F3S1, F1S3, F1S1, F1S4 and F2S3. The yield of S1 was the highest in Longqingdao 1 and the highest of F3S1 in fertilizer and water coupling, which was significantly higher than F3S4, F1S3, F2S3, F1S4 and F2S2 deal with.
