目前,水稻种子生产在追肥上主要是以氮、磷、钾营养元素为主,随着氮、磷、钾肥施用水平的提高,微量元素巳成为限制水稻产量提高的一个重要因素。“复合晶1号”微肥含有十几种植物必需的矿质元素,可以防止水稻各种缺素症,提高产量。本试验旨在探索“复合晶1号”微肥对水稻增产的最佳浓度,为生产上大面积种用提供参考。 At present, rice seed production mainly consists of nitrogen, phosphorus and potassium nutrition elements. With the application of nitrogen, phosphorus and potassium fertilizer increased, trace elements have become an important factor limiting rice yield. “Composite Crystal No. 1 ” Micro-fertilizer contains more than a dozen kinds of plant essential mineral elements, can prevent a variety of rice-deficient disease, increase production. The purpose of this experiment is to explore the optimum concentration of “Simian 1” micronutrient fertilizer to increase yield of rice and provide a reference for large-area seed production.
