【摘要】 在年生湿地松、马褂木苗木出圃前,根据苗木不同生长状况,随机选定块样地进行土壤理化性质 1 10 测定,经统计学处理,了解土壤肥力与苗木生长的相关性,探讨圃地土壤肥力特征和影响苗木生长的主要土壤属性,初步探讨如何对土壤肥力水平进行等级评定。由于该地土壤类型为水稻土,故对水稻土育苗提出一些见解。其研究结果将对培育壮苗,提高苗圃土壤管理水平有一定参考价值。更多还原

【Abstract】 Determination was made on soil physical and chemical properties in 10 random sampling plots according to different 1-year Pinus elliottii and Liriodendron chinense seedlings growth in a nursery for understanding relations between soil fertility and seedling growth, for making clear nursery soil fertility characteristics and major soil properties influencing seedling growth and for evaluating soil fertility. The nursery soil type was rice soil. Propositions were made on seedling cultivation on rice soil.更多还原
