为明确寒地盐碱地区水稻高产栽培行株距和穴苗数配置及高产行株距配置下垦鉴稻5号产量及品质特征,采用裂区设计,于2009年对黑龙江大庆盐碱地区主栽水稻品种垦鉴稻5号进行不同行株距配置、群体结构优化研究。结果表明,大庆盐碱地区采用6株苗/穴、株距10厘米、行距30厘米的配置可以获得高产(9896.90千克/公顷),垦鉴稻5号理论产量较常规配置(4株
In order to clarify the yield and quality characteristics of Kenjian 5 under high-yielding cultivation of rice in high-yielding cultivation of salt and saline soil in cold region, Kam rice on the 5th line spacing configuration, population structure optimization. The results showed that 6 seedlings / plantlets were used in Daqing saline-alkali region, with high yield (9896.90 kg / ha) with a spacing of 10 cm and a row spacing of 30 cm. The theoretical yield of Kenjian 5 was 4
