南方岩溶山区低产稻田复合生态农业模式试验初报

A Preliminary Report on a Complex Eco-agro-model in Low Output Peddy Field in Southern Karst Region

本试验应用农业生态学原理和现代农业技术,在我国广西岩溶山区低产水稻田应用稻+蔗+鱼+菇+菜复合生态农业模式,实现了每公顷稻田年产稻谷4.65吨,甘蔗24.65吨,鱼0.77吨,平菇15.5吨,蔬菜2.33吨,总产值54411元,纯收入34935元,资金产投比2.79:1,比对照(仅种双季稻)的产值增加8.4倍,纯收入增加10.1倍,取得了显著的经济效益和生态效益。

Experiments on a complex eco-agro-model: rice+sugarcane+fish+mushroom+vegetables,were carried out in Guangxi Karst Region in Southern China according to the principles of agroecology and the technologies of modern agriculture. The results showed that annual output per hectare reached 4. 65t for rice,24. 65t for sugarcane,0. 77t for fish,15. 50t for mushroom and 2. 33t for vegetables with a total output value at 54411 Yuan.net income at 34935 Yuan. The ratio of output - investment was 2. 79:1. The output value was 8. 4 times higher than that of the controlled (double cropping of rice) ,and net income was 10. 1 times higher than that of the controlled.
