良好的土壤生态条件,是农业高产稳产的物质基础。有机培肥地力,是我国几千年来农业的传统经验。我区耕地后备资源有限,只能靠提高单产来增加总产。我区地处热带亚热带,高温多湿,土壤风化强,微生物分解怏,养分淋溶作用大,农田土壤养分缺乏,肥力不高,作物产量不高不稳。要培育肥田沃土,恢复、建立和维护良好的农田土壤生态,取决于增加土壤有机质,走有机农 Good soil ecological conditions, is the material basis for high and stable agricultural production. The fertility of organic fertilizers is the traditional experience of agriculture in our country for thousands of years. I reserve arable land reserve resources is limited, only by increasing yields to increase total output. My area is located in the tropical and subtropical, hot and humid, strong weathered soil, microbial decomposition 怏, nutrient leaching, soil nutrient deficiencies, low fertility, crop yield is not high and unstable. To cultivate fertile fertile soil, restore, establish and maintain a good soil ecological farmland, depending on the increase of soil organic matter, take the organic farming
