红壤稻田多元复合种植模式研究

Studies on multiple cropping pattens in the rice field of red soil area:

实行冬春季蔬菜、马铃薯，春夏季玉米间作西瓜或蔬菜、早稻，秋季杂交晚稻的一年三季四收或四季四收的种植模式，土地生产率、劳动生产率、投入产出率、物质利用率等都比较高，适宜在浙江省红壤水田推广；肥豆稻、肥玉米稻模式，劳力资金投入少，在土劳负担重的地区可以推广应用。

Higher land and labor productivity, high output/input ratio and improved matter utilization were obtained by harvesting 4 times in one year, during which vegetables and potato were planted in winter and spring seasons, corn was intercropped with water melon or vegetables, or early rice in summer, hybird rice was relayed in autumn. these patterns can be applied to red soil area in Zhejiang province. Green manure(GM)-soybean(SB)-later rice and GM-corn-rice demanded low labor and cost input, and can be applied in labor and shortage areas.
