摘要
本文利用浸种、拌种进行了硝酸稀土对牧草种子萌发及幼苗生长、营养物质积累的效应研究。结果表明 ,10 0× 10 - 6稀土溶液 (以稀土氧化物计 )浸种 ,能极大地提高种子发芽率。播种后 ,幼苗生长健壮 ,出苗多 ,生物量增加 ,同时叶绿素、糖份、蛋白质含量也相应提高 ;以 1g硝酸稀土 (以稀土氧化物计 )拌 1kg种子进行播种 ,得出同样的结论。可见 ,稀土的应用有利于牧草种子萌发和幼苗的生长。
Effects of rare earth nitrate on the germination of seed,growth of seedling and the accumulation of nutrient of herbage have been studied with the methods of seed soaking and seed dressing.The results show that if the seeds were soaked in 100×10 -6 rare earth nitrate solution,not only the germination percentage increased largely,but also the rate of emergence increased,the seedlings grew vigorous and the contents of chlorophyll,suger and protein increased as well.The similar results were obtained by seed dressing with rare earth nitrate(1g/1kg).
