摘要
普格县是烤烟的重要产区,为查明其植烟土壤的肥力状况,本研究在普格县大坪乡、黎安乡、螺髻山镇、普基镇、荞窝镇、特兹乡、文坪乡、向阳乡、永安乡九个主要产烟乡镇采集了132个土样点进行养分特征分析。结果表明:普格县植烟土壤pH值处于适宜范围;土壤有机质较为丰富,但各地分布不太平衡;土壤速效氮含量偏低,速效磷含量较高,速效钾相对缺乏,交换性钙含量丰富,交换性镁含量偏低。在生产过程中,应根据各乡镇的具体情况,进行科学施肥,实现烤烟优质高效生产。
Puge was a major producing area of tobacco.In order to investigate the soil fertility situation in the main tobacoo-growing areas,the soil nutrient status in tobacoo planting areas of some townships in Puge county were studied in this paper.The soil samples which were collected from nine townships of Puge county,Daping,Lian,Luojishan,Jipu,Qiaowo,Tezi,Wenping, Xiangyang,Yongan,were analyzed.The results showed that the pH values of tobacoo planting areas of Puge county was in normal concentration;the soil was found to be rich in organic matter while the content was not in balance.The available nitrogen and available potassuim content in most soils were deficient while the available phosphors content was high.The exchangeable calcium was found to be rich while the exchangeable magnesium was dificient.Therefore,it was suggested that the management of soil fertility should be based on the particular situation in order to sustain the high productivity of flue-cured tobacoo.
