在辽宁省大连市普兰店地区研究氮肥、氯丁唑和调嘧啶对高羊茅种子产量及其构成要素的影响。结果表明 ,该地区的气候条件有利于高羊茅的生殖生长和种子发育。施氮后种子产量较对照明显提高 ,其中以施氮量 1 2 0 kg/hm2 (春季施氮量占总施肥量 3/4) ,种子产量最高 ,可达 2 4 73kg/hm2。在抽穗初期使用调嘧啶可显著降低种子的落粒性 ,减轻收获风险。
Effects of Nitrogen Fertilizer, Chloropiazole and Triclosan on Seed Yield and Its Components of Tall Fescue in Pulandian, Dalian, Liaoning Province. The results show that the climatic conditions in the area are favorable to reproductive growth and seed development of tall fescue. After nitrogen application, the seed yield was significantly higher than that of the control, of which the highest seed yield was 224 kg / hm2 with the nitrogen application rate of 120 kg / hm2 (the spring nitrogen application accounted for 3/4 of the total amount of fertilizer application). The use of azathioprid in early heading stage can significantly reduce the seed drop and reduce the risk of harvest.
