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。
Cultivated land in karst peaks and potholes can be divided into three types: depression bottom, banded terrace and high slope stone cave. The traditional corn + soybean planting pattern has very low output value on all three types of cultivated land, and needs to adjust the variety structure and reform the planting pattern. This paper reported four kinds of fruit-drug compound planting experiments based on the characteristics of three kinds of arable land, namely, Pomelo + Gynostemma, Loquat + Shegan + Euonymus fortunei, Seedless Wax + Shegan + Euonymus fortunei, honeysuckle. The preliminary results show that all four modes can greatly increase the output value of arable land and can be used as an important model for the sustainable development of eco-agriculture in the peak-depression area of karst peaks.
