为探讨不同播种量对白三叶草生长、产量、越夏率以及对杂草生物量控制的影响,于2012年10月至2013年11月在幼龄杨梅园开展白三叶草不同播种量研究。结果表明,随播种量增加,白三叶草出苗数、草层高度呈上升趋势,而茎粗、叶片SPAD值和单株鲜重均呈下降趋势。白三叶草鲜草产量随播种量的增加显著增加,播种量<15.00千克/公顷时,增加幅度较大,处理间达
In order to investigate the effects of different seeding rates on white clover growth, yield, over-summer rate and its impact on weed biomass control, different seeding rates of white clover were studied in young orchard from October 2012 to November 2013. The results showed that as the sowing rate increased, the number of emergence of white clover and the height of grass layer showed an upward trend, but the stem diameter, leaf SPAD value and fresh weight per plant all showed a decreasing trend. White clover fresh grass yield increased significantly with the sowing rate, sowing rate <15.00 kg / ha, a larger increase rate, the processing room up
