摘要
为了大力推广保山市农业科学研究所育成的高产稳产、多抗广适的大穗型饲料大麦新品种保大麦16号,研究了保大麦16号最佳播种密度和氮肥用量。结果表明,在密度210万/hm^2、氮肥用量750kg/hm2时,保大麦16号的产量最高。但结合效益分析及农业部制定的《到2020年化肥使用零增长行动方案》,保大麦16号最适宜密度为210万/hm^2,最经济环保的氮肥用量为全生育期施尿素450kg/hm^2、种肥和作分蘖肥各50%。该研究为保大麦16号的大面积标准化生产提供科学依据。
In order to extend the new variety Baodamai 10 in Baoshan City, we researched its optimal sowing density and nitrogen fertilizer dosage. Results showed that under 2 100 thousand plants/hm 2 sowing density and 750 kg/hm 2 nitrogen fertilizer dosage, the yield of Baodamai was the highest. Combining with the benefit analysis and the Action Plan for Zero Growth in Fertilizer Use until 2020, the optimal density for Baodamai 16 was 2 100 thousand plants/hm 2, and the most economical and environmentally friendly dosage for nitrogen fertilizer was 450 kg/hm 2 in the whole growth period, seed manure and tillering fertilizer were both 50%. This research provided scientific basis for the large-scale standardized production.
