对2003～2005年在新兴县开展的水稻实地养分管理技术(实地法)示范进行了总结。结果表明:与当前习惯法相比,实地法施肥更趋合理,具有合理利用养分资源的特点。尽管减少了肥料用量,稻谷产量仍显著增加;多年多点示范都表现节支增收增效和安全等优点,具有良好的重现性,是一项值得大面积推广应用的水稻养分管理新技术。
This paper summarizes the rice field nutrient management techniques (field method) demonstration carried out in Xinxing County from 2003 to 2005. The results showed that compared with the current customary law, the field fertilization is more reasonable and has the characteristics of rational utilization of nutrient resources. Although the amount of fertilizer is reduced, the output of paddy is still significantly increased. The demonstration for many years shows the advantages of cost-saving, efficiency and safety-saving, with good reproducibility. It is a new rice nutrient management technology worthy of popularization and application in a large area.
