摘要
Abstract
A five－ year field experiment was carried out on clay-calcic cinnamon soils for studying effects of applying coal ash, green manurie and chemical fertilizer on clay-calcic cinnamon soil.The results showed that application of coal ash was capable of improving the soil properties such as porosity, texture volumetric weight,availability of nutrients and microbial activity. It was optimized that a protocol with application of coal ash. nitro-phosphate 880.5 kg· hm－ 2 and green manure 13 t could produce as high as 6 t of wheat with net increase of 400 kg per hectare.关键词
