摘 要:根据不同坡位上红壤的理化性质分异,建议在红壤丘陵上推行“顶林、腰园、谷农、塘渔”生态农业模式。并在塘边建造猪场,以养猪为纽带,实行种养结合,建立饲草-猪-沼、菇-果、粮-鱼、珍珠的食物链,再定量调控种养结合链环的饲料配置,粪尿投放、制沼育菇和塘淤返田,以提高系统生产力,达到农业可持续发展。An ecological agriculture pattern:forests(at hilltop) tea and fruit gardens(at hillside) cropping(in valley) fishery(in pond)is suggested to be popularized on the hilly red soil regions,This pattern should be adjusted according to the difference of physical and chemical characters of the red soils at different slope positions.Pig farm is built by ponds and a food chain,which consists of grass(forage) hog(dung) marsh gas,mushroom fruit,(crops) fish(pearl),is formed.On this basic,food is compounded,dung is put into the ponds,marshgas and mushroom is produced and pond silt is dug back to the field.All these were quantitatively managed for increasing systematic productivity and agriculture sustainable development.
