为求经济合理施用化肥,发挥每单位化肥施用量的最大增产效益,自1985年起,以杂交水稻为材料,从探明不同施氮量和施肥法之间的互作效应入手,连续两年进行了有关省肥高产栽培新途径的研究。以下是部分试验结果。
In order to economically and reasonably use chemical fertilizers and maximize the yield increase per unit of chemical fertilizer application, hybrid rice has been used as raw material since 1985, starting from the interaction effect between different nitrogen application rates and fertilization methods for two consecutive years Carried out on the province of high-yield cultivation of new ways of research. The following is part of the test results.
