对陈永康水稻丰产经验的研究表明,在中性水稻土上调节水稻的土壤氮素营养状况是达到丰产的关键。这就是根据土壤的氮素供应特点、因土制宜地运用肥水措施,调节水稻生长发育过程中的土壤氮素供应状况,以满足水稻器官协调生长的共同要求。因此,必须研究土壤理化生物学性质对土壤氮素供应状况的影响,以及肥水措施对氮素供应状
The research on Chen Yongkang’s high yield rice experience shows that it is the key to achieve high yield by regulating the nitrogen status of soil in neutral paddy soil. This is based on the characteristics of soil nitrogen supply, due to soil and water measures to adapt to the soil growth and development of rice in the process of nitrogen supply to meet the coordinated growth of rice organs common requirements. Therefore, we must study the physical and chemical properties of soil nitrogen on the status of soil supply, as well as fertilizer and water measures on the supply of nitrogen
