摘要
为探索钾肥对泽泻生长的影响,进而为泽泻合理施肥提供科学的理论依据。在氮肥、磷肥相同的情况下,进行了不同钾肥用量及施用时期对泽泻生长发育影响的试验。结果表明施用钾肥有利于提高泽泻块茎的干重和鲜重,钾肥用量15g/m2时最有利于增加泽泻块茎的重量,且钾肥作为底肥一次性施入为好。
In order to explore potash Alisma growth,and thus Alisma rational fertilization scientific theory.In the case of the same nitrogen,phosphorus,different potassium application rate and application time on Alisma growth and development of the test.The results show that the application of potash to improve the Alisma tuber dry weight and fresh weight,potash dosage of 15g/m2 help to increase the weight of Alisma Tuber and potash fertilizer as base fertilizer was applied at once as well.
