本文着重从农艺性状、农化及生化指标方面,对不同耐性的耐低钾水稻品种的特性进行比较研究。结果表明,耐性强的品种对低钾环境具有很好的适应性,较容易从低钾环境中吸收更多的钾素营养;优良的根系是其耐低钾本能的关键所在。 This article focuses on the characteristics of agronomic traits, agronomy and biochemical indicators of different tolerance to low potassium rice varieties were compared. The results showed that the tolerant cultivars had a good adaptability to low potassium environment and were more likely to absorb more potassium nutrients from the low potassium environment. The excellent root system was the key to their resistance to low potassium.
