Paddy field paddy rice Ping fish three-dimensional planting and breeding is a kind of rice paddy and Yang Ping, fish together organically, to change the simple plane paddy rice paddy rice paddy, water surface watering, water fish, rice Ping Fish Trinity three-dimensional agricultural structure. Since 1992, Jingning County has experimented and experimented in a single cropping rice area to demonstrate the three-dimensional planting and cultivation techniques of paddy rice and Pingyang in the paddy field. The project has been popularized and implemented in the “Three-Third” project of agriculture so that it will become a highly efficient An important technique in agriculture. 1. Comprehensive benefits (1) Ecological benefits Single-cropping paddy rice Pingyang three-dimensional planting and breeding make full use of water, heat, light and gas resources, cut due to paddy field weeds and floating
