Embodiment 1
[0021] at 15m 2 The area of the plot is taken as an example, sowing time: according to the climate conditions in Lanzhou, in late April every year, when the temperature is stable above 15°C, sowing can be done; site conditions: general cultivated farmland soil is enough, the moisture content of the cultivated layer is 35%, the surface Temperature 15°C. Harvesting time: the first ten days of September for grass mowing, and the second ten days of October for harvesting fields.
[0022] 1. Ditch sowing
[0023] After leveling the land and applying sufficient base fertilizer, ditching is carried out at a row spacing of 90 cm, with a depth of 10 cm and a width of 15 cm. Sow seeds at the bottom of the ditch with a seeding rate of 1.0 kg / mu and a sowing depth of 2 cm.
