摘要/Abstract

摘要： 通过静态水溶试验和草坪施肥试验, 研究了高分子聚合物包膜尿素( PCU) 的养分释放特性
及春季一次性施用对高羊茅草坪生长的影响。结果表明, 由于肥料所处环境温度不同导致实验室静态水溶法测定PCU养分释放速度快于其在田间的实际释放速度。田间试验中一次性施用该肥料可以满足高羊茅草坪整个春季生长对氮素养分的需要; 与尿素和市场上的草坪肥料相比, 草坪质量无显著差异, 且草坪生长速度均匀, 草屑量相对较少, 起到了减少草坪修剪次数降低养护强度的作用。

Abstract: The nitrogen release characteristic ofmacromolecule polymer coated urea ( PCU) by laboratory method of water dissolve and the effects of app lied PCU on tall fescue turf as basal app lication in spring was studied. The results showed that the rate of PCU nitrogen release by laboratorymethod ofwater dissolve is faster than the rate in the turf field because of their different circumstance temperature affect. Applying PCU once in early sp ring could meet nitrogen need of tall fescue growth in sp ring season. Compared with urea and turf special fertilizer, no significant difference was observed in turf quality. So, app lied PCU p lay an important role in reducing turf maintenance strength through keep ing even growth of turfgrass and less clippings production.

Key words: tall fescue, coated urea, p reliminary solubility, differential solubility, turf quality
