| 摘 要： | 通过调查研究和测定分析,甘肃省有机肥资源总量是13405.3万吨,有机肥利用量5846.43万吨,利用率为43.6%,且品种全,富含氮、磷、钾养分。人畜粪尿、作物秸秆、绿肥、饼肥四种肥源贡献N,P2O5,K2O养分总量达到204.36万吨,是1999年甘肃省化肥施用量的63.4万吨的3.22倍,重视有机肥养分资源的再循环利用,有利于农业的可持续发展。

| Abstract: | Through the inquisition and analysis,the total amount of organic manure resource was 13405.3×104t in Gansu province,and use amount of organic manure was 5846.43×104t in 1999.The total contributing amount of N,P2O5 and K2O nutrient came to 204.36×104t from human-animal feces and urine,crop straws,green manure and seedcakes manure,which was 3.22 times of the use amount of 63.4×104t from chemical fertilizers.Hence,more attention should be paid to the recycling utilization of nutrient resources in organic manure to sustain agricultural development there. |
