摘要
试验通过4种不同浓度的磷肥应用于无土育秧板水稻育秧,分析比较其对水稻形态指标、生理指标的影响,旨在筛选适宜于水稻幼苗生长的最佳磷肥浓度。结果表明,磷肥施用量在225kg/hm2,水稻秧苗的综合素质最佳。
In this experiment,four phosphate fertilizers of different concentrations were used in soilless seedling plate rice seedling cultivation to study their effects on the morphological and physiological indexes of rice,so as to select the optimal phosphate fertilizer concentration suitable for the growth of rice seedlings from this experiment. The results showed that the application of 15 kg phosphate fertilizer per mu could make the comprehensive quality of rice seedlings optimal.
