| 摘 要： | 不同的区域不同的土壤肥力有不同的施肥量，为指导农户在免耕超级稻的种植上合理施用钾肥，达到科学施肥、实现节本增收的目的，进行不同施钾量对免耕超级稻生长发育、产量影响的试验。试验结果表明：在浅铁沙子土的水田，免耕超级稻施k20量在7～21kg／667m^2的范围内，各处理间差异明显，以14kg／667m^2施用量的节本增收效果最高，比对照增产35％、节本增收206．1元。

| Abstract: | There are different fertilizer applying amount for different soil fertility in different districts. In order to guide the farmers in rational application of K fertilizer for no-tillage super rice cultivation and to reach the objective of cost-saving ＆ income-increase, an experiment was conducted for the impacts of different applying amounts of kalium on the growth and yield of no-tillage super rice. The results show that in shallow iron-sandy paddy field of Gangbei District, the applying amount varying from 7-21 kg/667m^2 , there are obvious differences between treatments and the applying amount of 14kg/667m^2 has the best effect with yield increase of 35% than control treatment and cost-saving ＆ income-increase of 206.1 Yuan. |
