通过 5年试验研究 ,完成了对寒地水稻品种的一般性分类 ,阐述了穗重型品种 (单穗重大于 2 5g)采取穗数型栽培获得高产的观点 ;进一步规范了寒地水稻低成本钵育苗技术规程 ;提出了以“平稳促进”为原则的本田管理模式 :即将氮、磷、钾比例调整为 1∶0 4∶0 6 ,前后期氮肥比例为 :5∶5偏 6∶4∶ ,磷肥后移 2 0 % ;本田生育期内灌溉定额控制在 30 0m3 /6 6 7m2 (不包括自然降水 ) ,实行浅水 (0～ 3cm)间歇灌溉 ;丁草胺用量控制在 2 0kg/hm2 以下。试验示范模式实现了单产6 5 0～ 70 0kg/ 6 6 7m2 ,节本 5 %的指标 Through five years of experimental study, the general classification of rice varieties in the cold region was completed, and the view was given that the panicle type (single spike> 25g) The technical regulation of nursery stock was put forward. The Honda management mode based on the principle of “smooth promotion” was proposed: the proportion of nitrogen, phosphorus and potassium was adjusted to 1:04:06, the proportion of nitrogen fertilizer before and after the stage was: 5: 5 partial 6: Phosphorus fertilizer moved 20% later. During the growth period of Honda, the irrigation quota was controlled at 30 0m3 / 6 6m2 (excluding natural precipitation), intermittent irrigation with shallow water (0 ~ 3cm) and butachlor not more than 20kg / hm2. The pilot model achieved a yield of 650 ~ 70 0kg / 667m2, the index of 5%
