粳稻三系配套成功,是一项具有重大意义的科研成果。它必将推动水稻生产的发展,促进大幅度增产。杂交稻根系发达,长势旺盛,耐肥抗倒,穗大粒多,千粒重高,显示了较强的生长优势,展示了广阔的增产前景。为了充分发挥杂交水稻的高产优势,施肥技术是杂交稻栽培措施上的重要环节,因此,在杂交稻进行试验、示范栽培的同时,我们进行了杂交粳稻的高产施肥试验,以探讨杂交粳稻的适宜施肥法,以及不同生育时期对氮肥需要的内在规律,为杂交稻的高产栽培提供依据。
Japonica rice three series of successful, is a significant scientific research. It will surely promote the development of rice production and promote a substantial increase in output. Hybrid rice developed root system, strong growth, resistance to lodging, spike large grain, 1000-grain weight, showing a strong growth advantage, showing a broad prospect of increasing yield. In order to give full play to the advantages of high yielding hybrid rice, fertilization technology is an important part of hybrid rice cultivation measures. Therefore, in hybrid rice experiments, demonstration cultivation, we conducted high-yield fertilization experiments of japonica hybrid rice to explore the appropriate hybrid japonica rice Fertilization method, as well as the inherent law of the need of nitrogen fertilizer in different growth stages, provide the basis for high-yielding cultivation of hybrid rice.
