一、台湾的主要复种方式台湾耕地总面积918143公顷,其中,水田面积占56％,为517061公顷,旱地占44％,为401082公顷。水田的复种方式依水源情况而定,在灌溉设施齐全、可保证全年供水的地区,一般为双季稻,这一面积约占耕地总面积的40％以上,为396010公顷。而在只能保证短期灌溉其余期间依靠降水的地区,则根据水源情况种植一季稻或采用轮作的复种方式。其中,一季稻种植面积约占耕地总面积的5％左右,为49984公顷,每隔2、3年种植一季水稻的轮作田面积约占10％,为98067公顷。
I. Main Multi-cropping System in Taiwan The total area of cultivated land in Taiwan is 918,143 hectares, of which paddy field area accounts for 56% to 517061 hectares and dry land accounts for 44% to 401,082 hectares. The method of multiple cropping in paddy fields depends on the situation of water sources. In areas where irrigation facilities are complete and can supply water throughout the year, they are generally double-cropped rice. This area accounts for over 40% of the total cultivated area, at 396,010 hectares. In areas where precipitation can only be guaranteed for the rest of the short-term irrigation, one-cropping or cropping by crop rotation is based on the source of water. Among them, the area under first-season rice planting accounts for about 5% of the total cultivated land area, which is 49,984 hectares. The area of paddy fields that grow one-season rice every 2-3 years accounts for about 10% to 980.67 hectares.
