摘 要：
针对近年珠三角地区菜田连作出现的突出问题,采用“123种植模式”(菜-中晚稻-菜”轮作模式)与当地传统的“早稻或晚稻-蔬菜”轮作及蔬菜连作等几种模式进行经济效益比较分析。结果表明,“123种植模式”的经济效益最佳,其中“白瓜-中晚稻-番茄”模式每667 m2的年产值和年纯收益分别达到12 377元和10 931元,实现了在最有利于种植高效作物的高效生产时段优先安排种植高效作物,并较好地发挥了作物间对气候、土壤生态条件利用的互补作用,从而达到耕地综合效益最大化。

摘 要：
To solve the serious problem caused by continuous cropping of vegetable in the Delta of Zhujiang River,the rota-tion of "vegetables"rice of intermediate-late maturity in one-cropping season"vegetables" was adopted and its economic bene-fits were compared with other traditional patterns such as the rotation of "123 farming pattern"(rice of early or late maturity in double-cropping season vegetable) and continuous cropping of vegetable.The results showed that "123 farming pattern" could produce most economic benefits,the output value and net income of the rotation of "Cucumis melo L.var.conomon-rice of intermediate-late maturity in one-cropping season-tomato" reached 12 377 yuan/667 m~2 and 10 931 yuan/667 m~2 per year,respectively.Thus it accomplished the maximum integrated economic benefits by planting valuable crop in favorable duration and exploiting such ecological factors as climate and soil to cultivate different crops which can coordinate well.
