摘 要：
取油菜叶片样和相应的表层土样各２３７个分析结果表明：土壤中锌、锰缺乏的频率分别为４８９％、６２５％，植物中硼缺乏的频率为８３５％。锌缺乏频率较高的土类为灰潮土、黄褐土、黄棕壤和紫色土。其中以黄褐土有效锌平均值最低，仅０７０ｍｇ／ｋｇ。土壤有效铜平均值高于临界值。油菜叶片中硼、氮较为缺乏，以灰潮土油菜叶片中有效硼最低，为７８ｍｇ／ｋｇ；氮低于５３ｇ／ｋｇ的样点占调查样点的４０％～１００％，叶片中其他元素含量均较丰富

摘 要：
Total 237 soil samples and rape leaf samples(Youngest mature leaf) were taken from farmers' fields in main rape productive area of Hubei Province during 1993 1996. Levels of nutrients which were analyzed predicted and diagnosed nutrition disorder in oil rape. The main results were as follows: Zinc and manganese deficiency in soils and Boron deficiency in oil rape leaves were found in this area and the percentage of soil available Zn, Mn and leaf B under critical levels were 48.9%, 62.5%and 83.5% respectively. Zn deficient soils are yellow cinnamon soil, yellow brown soil and purple soil. Boron deficient soils are calcareous alluvial soil, alluvial purple soil and yellow cinnamon soil. The other nutrients are adequate.
