我区岩溶地貌广泛分布,在岩溶地貌区域分布的棕色石灰土,多利用来栽培玉米、甘蔗、花生、黄豆等旱地作物;也有部分辟作稻田,栽培水稻或水旱轮作。看来分布在较平坦地形的棕色石灰土,用于扩大甘蔗栽培是很有利的。但是目前在棕色石灰土上栽培甘蔗,一般产量较低。据土壤普查资料,棕色石灰土含钾低;可能是引起甘蔗产量较 Karst topography in our area is widely distributed. Brown limestone soil distributed in the karst topography area is mostly used to cultivate dryland crops such as corn, sugar cane, peanut and soybean. Some paddy fields are also used for rice cultivation or rotation. It appears that the distribution of brown limestone in a relatively flat terrain is advantageous for expanding sugar cane cultivation. However, sugarcane is currently cultivated on brown lime soil, with lower yields. According to soil census data, brown lime soil with low potassium; may be caused by more sugar cane production
