谷子新品种长生08的选育及高产栽培

Breeding and High Yield Cultivation of New Millet Variety Changsheng 08

长生08是山西省农科院谷子所选育的谷子新品种,该品种优质高产、抗病抗倒,2011年通过了国家新品种鉴定。为促进该品种大面积推广,采用正交设计试验方法,研究了播种期、留苗密度、肥力水平对长生08产量的影响。结果表明,旱薄地留苗密度对长生08产量影响最大,旱肥地播期对长生08产量影响最大。结合实际生产情况,制定了长生08的最佳高产栽培模式:在旱薄地,长生08的适宜播期为5月15—25日,最佳公顷留苗数45万株,施有机肥24 t/hm2和化肥700 kg/hm2;在旱肥地,长生08的适宜播期为5月15日,最佳公顷留苗数37.5万株,施有机肥24 t/hm2。

Changsheng 08 is a new millet variety with the characteristics of high quality, high yield, disease and lodging resistance bred by Institute of Millet, Shanxi Academy of Agricultural Sciences. To promoting the planting of this variety in large scale, the effects of sowing date, planting density and soil fertility on the yield of Changsheng 08 were studied by orthogonal design. The results showed that the yield was the highest with optimal sowing time of May 15-25, plant density of 450 000 plants/hm2, applying 24 t/hm~ organic manure and 700 kg/hm2 chemical fertilizer on the barren dry land; the yield was the highest with optimal sowing time of May 15, plant density of 375 000 plants/hm2, applying 24 t/hm2 organic manure on the fertile dry land.
