以“川草2号”老芒麦(Elymus sibiricus L.cv.chuancaoNO.2)为试验材料,采用不同底肥、不同施肥量和不同行距等处理对“川草2号”老芒麦进行种子丰产栽培技术研究,以期为“川草2号”老芒麦种子生产管理技术提供依据。结果表明:复合肥作底肥施肥量为120 kg/hm2的平均种子产量最高,达1 612.26 kg/hm2,施肥量为120 kg/hm2比较适合老芒麦种子生产。施肥量过高,不但浪费资金投入,而且不利于“川草2号”老芒麦种子生产;复合肥作底肥行距为60 cm的种子产量最高,为1 534.5 kg/hm2,在红原进行“川草2号”老芒麦种子生产,行距60 cm比较适合。
With “Eupolyphaga sinensis 2” Elymus sibiricus L.cv.chuancao NO.2 as test material, using different base fertilizer, different fertilizer rates and different row spacing and other treatments on the Wheat seed yield cultivation techniques, with a view to “Chuancao No. 2 ” Eupatorium seed production and management technology to provide the basis. The results showed that the compound fertilizer had the highest average seed yield of 120 kg / hm2 at the base fertilizer application of 1 612.26 kg / hm2 and the fertilizer application of 120 kg / hm2, which was more suitable for the seed production of Erigeron. Fertilizer is too high, not only a waste of capital investment, and is not conducive to “Kawakusa 2” sage seed production; compound fertilizer at the bottom line spacing of 60 cm seed yield highest, Conduct “Chuancao No. 2 ” Sarkoskey seed production, spacing 60 cm more suitable.
