| 摘 要： | 运用已持续26年的湖南祁阳红壤站长期肥料试验的水稻植株样品研究长期施用含氯化肥对水稻的养分吸收和水稻生长的影响。结果表明:长期施用含氯化肥已显著减少水稻吸收P、Ca、Mn、Cu、Si,并抑制Cu、Zn、Si和P向籽粒运输,导致水稻结实率降低,倒伏率提高。

| Abstract: | Samples of rice plants gathered from the Long-term Fertilizer Experiment, located in Qiyang, Hunan Province and established in 1975, were used to investigate effects of applying chlorine-containing chemical fertilizers on growth and nutrients absorption of rice. Results indicate that: Application of chlorine-containing chemical fertilizers decreased significantly some nutrients (P, Ca, Mn, Cu, Si) uptake of rice. Otherwise, the application curbed transportation of Cu, Zn, Si and P within plant of rice. As a result, rice grain form ratio was lower and lodging ratio was higher in treatments with the application than treatment without the application. |
