摘要
为了解双江植烟区域土壤养分丰缺状况,于2021年在双江沙河乡、勐勐镇、邦丙乡、大文乡、忙糯乡5个主要植烟乡镇进行土壤养分调查,共采集49份土壤样品.通过检测土壤养分含量,并对其进行评价.结果表明,双江县植烟区土壤整体呈酸性、微酸性,平均pH为5.28,其中酸性土壤占全县的77.55%;土壤有机质、水解性氮含量中等,速效磷、速效钾含量偏高,土壤交换性镁、有效锌含量分布较广,有效硼含量中等偏低,水溶性氯离子含量很低.
Abstract
In order to understand the abundance and deficiency of soil nutrients in the Shuangjiang tobacco planting area.In 2021,soil nutri-ent surveys were conducted in five major tobacco planting townships in Shahe Township,Mengmeng Township,Bangbing Township,Dawen Township and Mangnuo Township,and a total of 49 soil samples were collected.Soil nutrient content was analyzed and evaluated by testing.The results showed that the soil in the tobacco planting area of Shuangjiang County was acidic and slightly acidic,with an average pH of 5.28,of which acidic soil accounted for 77.55%of the county.The content of soil organic matter and hydrolyzed nitrogen was medium,the content of available phosphorus and available potassium was high,the content of exchange magnesium and available zinc in soil was widely distributed,the content of available boron was moderately low,and the content of water-soluble chloride ions was very low.
