Abstract

The invention relates to a method for sowing triticale in the autumn in the Qinghai lake area and gannan prefecture of the Qinghai-Tibet Plateau. The method comprises the following steps: (1) fertilizing sowing fields of all regions of Haibei, Hainan and Huangnan regions of Qinghai province, Tianjun county of Haixi region, Gannan region of Gansu province, Qinghai lake area and gannan prefecture of Qinghai-Tibet Plateau of Eastern Qilian Mountains, ploughing and rubbing to flatten soil; (2) performing drill sowing or broadcast sowing on the triticale series 5012 on the sowing fields obtained in the step (1) in late August to early September every year; (3) dressing nitrogen 90-110kg / hm2 respectively in the tillering stage and jointing stage before raining after the triticale turns green in middle March of the second year; and (4) cutting with labor or a mountain mower when the triticale is in the flowering period in late June. The method has high grass yield in unit area, can be used for increasing the coverage of the region for soil surface in winter and spring to reduce water and soil loss, soil desertification risk and zokor harm, and has an important ecological value.

Description

technical field [0001] The invention relates to the technical field of forage grass, in particular to a method for sowing triticale in autumn around lakes in the Qinghai-Tibet Plateau and Gannan regions. Background technique [0002] Forage and fodder crops on the Qinghai-Tibet Plateau are sown in autumn mainly in the valleys of the southern Tibet Plateau and the valleys and mountains in eastern Qinghai, where the climate is relatively warm. The area around the Qinghai-Tibet Plateau and Gannan is located on the northeastern edge of the Qinghai-Tibet Plateau, including all three prefectures of Haibei, Hainan and Huangnan in Qinghai, Tianjun County in Haixi Prefecture, Gannan Prefecture in Gansu and the eastern section of Qilian Mountain. This area is the most suitable for large-scale contiguous areas of the Qinghai-Tibet Plateau. Areas for planting forage grass and mechanized operations. However, due to the cold climate in this area, the establishment of artificial grassland...
