中文摘要:
      为了探索不同增氧处理对杂交水稻吸收利用氮、磷、钾的规律,以杂交水稻深优9586为研究对象,采用模拟微区试验,对植株中的氮磷钾含量、土壤中的碱解氮含量进行对比研究。试验结果表明:不同增氧处理所收割每兜籽粒总重较常规对照组能实现增产23.27%~88.34%,收割时土壤碱解氮含量较常规对照组提高了9.09%~51.60%,说明增氧处理不仅有利于促进杂交水稻对氮磷钾营养元素的吸收利用,促进干物质的积累,达到提高产量的目的,还有利于提高土壤的速效氮含量,在常规对照处理组的碱解氮含量却低于移栽前土壤背景值情况下,所有增氧处理组收割后土壤中的碱解氮含量均大于移栽前土壤背景值。该试验更准确地反应了真实生长环境下不同增氧处理对杂交水稻水吸收利用稻氮磷钾的规律。
英文摘要:
      In order to explore the regularity of the absorption and utilization of nitrogen, phosphorus and potassium in hybrid rice with different aerobic treatments, a simulated microarea experiment on Shenyou 9586 was carried out to compare the content of N, P, K in the plant and alkali in the soil. The results show that with the different aerobic treatments the total weight of each pocket of grains can increase by 23.27% to 88.34% compared with that of the conventional controlled group, and that the content of alkali hydrolysable nitrogen in the soil increases by 9.09% to 51.60% when harvested, which indicates that the increase of oxygen is beneficial not only to the absorption and utilization of nitrogen, phosphorus and potassium, but also to the accumulation of dry matter and the improvement of the yield of the crop. Aerobic treatment also helps to improve the content of available nitrogen in the soil. When harvested, the content of alkali hydrolysable nitrogen in all the experimental groups is higher than that in the soil before transplanting, despite the fact that before transplanting, the former is lower than the latter.The experiment more accurately reflects the law of nitrogen and phosphorus and potassium intake of Hybrid Rice with different growth conditions.
