诸城植烟区主要基地单元土壤养分性状分析

Analysis of Soil Nutrient Characters in Main Tobacco Planting Bases of Zhucheng

为了解诸城烟区土壤养分状况,2012年在诸城5个基地单元共采集土壤样品230个,并进行分析化验。结果表明:全市土壤pH均小于7.5,大多属适宜范围,土壤碱解氮、有效磷、有效锌含量丰富;有机质、速效钾、有效硼含量较低。为此,提出增施有机肥和"控氮、稳磷、增钾、补硼"的施肥策略;各基地单元不同土壤养分因子丰缺情况差异较大,施肥应注意因地制宜。

In order to know the soil fertility situation of tobacco planting area ,230 soil samples were col- lected from five main bases of Zhucheng in 2012. The results showed that the pH value of soil samples were all lower than 7.5, and most were in the appropriate range ; the soil was rich in available N, P and Zn, but low in organic matter, available K and B. Therefore, the countermeasures were put forward as controlling N, stabili- zing P, increasing organic matter and K, and supplementing B; fertilization by adjusting measures to local conditions due to the large differences of soil nutrient factors among five bases.
