Abstract:

Use the ditches next to the idle vegetable greenhouses to grow rice, and implement interplanting rice and vegetables, can make full use of arable land resources, increase rice planting area and reduce agricultural non-point source pollution, and increase the species diversity to control pests and diseases. When multiple crops of vegetables are grown in plastic greenhouses, excess water and fertilizer will leak into the ditches. These leaking fertilizers can ensure the normal growth of rice in the ditches. Interplanting rice with greenhouse vegetables can realize the recycling of agricultural resources, with obvious economic, social and ecological benefits. It is a model innovation of sustainable agriculture.

Key words: rice, greenhouse vegetable, interplanting

摘要：

利用相对闲置的蔬菜大棚沟渠种植水稻，实施水稻与蔬菜间套种，既可充分利用耕地资源，增加水稻种植面积，又减少农业面源污染，同时增加物种多样性控制病虫害发生。试验示范结果表明，塑料大棚一年当中种植多茬蔬菜，会有多余的水肥渗漏到沟渠中，这些渗漏的肥料能够保证沟渠中水稻的正常生长。水稻与大棚蔬菜间套种可实现农业资源循环利用，经济、社会和生态效益明显，是可持续农业的一种模式创新。
