1997年文成县在樟台乡双季稻区推行了茄子(杭茄3号)—水稻(汕优10号)—蔬菜(早熟5号)新三熟栽培模式,简称“两菜一稻”。其中杭茄3号、汕优10号各124hm~2,早熟5号80hm~2,全年复种面积为328hm~2,总产值达1062.2万元。据对樟岭村5农户的调查,“两菜一稻”每667m~2产值达6336.58元,扣除成本,净收入4552.85元,比连作稻每667m~2净增514.5元,总增4038.35元。这种水旱轮作栽培模式,既有效地抑制了茄子青枯病和田间稗草,又改善了土壤结构,提高了土壤肥力,从而使菜稻获得双丰收。其配套技术如下:
In 1997, Wencheng County promoted the new three-crop cultivation mode of eggplant (Shanyou No.3) - rice (Shanyou No.10) - vegetable (early maturity No.5) in the double cropping area of Zhangtai Township, referred to as “two dishes and one rice”. Among them, Hangguo No.3 and Shanyou 10 each have 124 hm ~ 2, early maturity 5 80hm ~ 2, the annual area of double cropping is 328 hm ~ 2 and the total output value reaches 10.622 million yuan. According to the investigation of 5 farmer households in Zhangling Village, the output value of “two dishes and one rice” per 667m ~ 2 reached 6336.58 yuan, net of expenses was 4552.85 yuan, net increased 514.5 yuan per 667m 2 compared with that of paddy rice and the total increase was 4038.35 yuan. This crop rotation and rotation cultivation mode not only effectively inhibited eggplant bacterial wilt and barnyardgrass in the field, but also improved the soil structure and soil fertility so that the double harvest of cabbage was achieved. Its supporting technology is as follows:
