摘 要: | 为探索减氮条件下密度对望两优361产量的影响,2018年在马庙镇进行了该试验。试验结果表明:怀宁县单季稻施肥量应为:N:P:K=13.5:5.4:10.8。在此施肥量的基础上: 1.5万穴/667m<sub><sup>2</sup></sub>为最佳移栽密度。

Abstract: | To study the influence of transplanting density on the grain yield of wangliangyou 361 under nitrogen reduction condition, a field experiment was carried in Mamiao Town in 2018. The results showed that the fertilization rate of mid-season rice in huaining county should be: N:P:K=13.5:5.4:10.8. Based on the amount of fertilizer applied, 15,000 holes/667m<sub><sup>2</sup></sub> was the best transplanting density. |
