福州平原人多地少,光热资源丰富,据稻田研究结果,推广复种轮作三熟制,不但经济产量和经济效益高,且改善土壤理化性质,增加地力。三熟制比二熟制有较高的生产力。虽然从土壤中带走的养分较多,由于增加了土壤有机质来源,所以土壤并未衰退。麦、稻、稻三熟制有较高的生产力,在增施肥料的条件下,种麦不会损稻。 In Fuzhou Plain, there are many people with less land and plenty of light and heat resources. According to the results of paddy field research, the promotion of multiple crop rotation for three-cropping system not only has high economic yield and economic benefits, but also improves soil physical and chemical properties and increases fertility. Three cooked more than two cooked higher productivity. Although more nutrients were removed from the soil, the soil did not decline due to the increased source of soil organic matter. Wheat, rice, rice, three cooked system has a higher productivity, fertilizer conditions in the increase, the kind of wheat will not damage rice.
