【摘要】 岩溶峰丛洼地的耕地可分为3种类型:洼底平地、带状阶梯地和高坡石穴地。传统的玉米+黄豆种植模式在三种类型耕地上的产值均很低,需要调整品种结构,改革种植模式。该文报道了基于三种耕地特点的四种果-药复合种植试验,即沙田柚+绞股蓝、大果枇杷+射干+扶芳藤、无核黄皮+射干+扶芳藤、四月桃+金银花。初步结果显示,四种模式均可大幅度提高耕地的产值,可作为岩溶峰丛洼地地区生态农业可持续发展的重要模式。更多还原

【Abstract】 The cultivated lands in the karst peak-cluster depression area in Sanzhiyang of Du’an County can be differentiated into three kinds:small level grounds at the bottom of depressions,banding terraces around the foot of mountains and stone cave grounds around the half way up the mountains. The output value of those three kinds of cultivated land under the traditional interplanting model,in which maize is farmed together with soy bean,is very low. In order to raise the output value,the traditional variety structure has to be adjusted,and the interplanting mode has to be reformed. Four kinds of interplanting test between fruit trees and medicine plants which based on those land characteristic,such as Shatianyu+Gynostemma pentaphyllum,big fruit loquat +Belamcanda chinensis+Euonymus fortunei,high quality Wampee+Belamcanda chinensis+Euonymus fortunei,April peach+Lonicera japonica are reported. The preliminary result shows that the output value of cultivated land had been improved by those four kinds of interplanting mode by a big margin,so they can be regarded as the important sustainable development modes of eco-agriculture of the karst peak-cluster depression area.更多还原
