水稻无氮基础地力产量测定试验总结

摘要

The rice yield experiment was conducted based on the soil without nitrogen fertilizer application.The results indicated that the efficiency of nitrogen fertilizer was low.Precision application of fertilizer and decrease of nitrogen loss were effective ways to improve economic benefits.%通过对赣榆县赣马镇马厂村进行了水稻无氮基础地力产量的测定试验。结果表明：氮肥当季利用率较低,应精确定量施肥,减少氮肥流失,提高种稻经济效益。
