Manufacturing method of Stipa plant seed roll and seed roll spreading and sowing method

Abstract

The invention discloses a manufacturing method of a Stipa plant seed roll and a seed roll spreading and sowing method. A Stipa collecting net is a seed sticking net formed by weaving multiple coarse wool yarn, short fluff is arranged on the wool yarn for weaving the seed sticking net, a manufactured Stipa collecting net is dragged on the grass, and Stipa seeds are attached to the Stipa collectingnet by long awn of Stipa plant seeds and hard barbs at bottoms of the seeds; the Stipa collecting net with the Stipa seeds is rolled into a cylindrical seed roll with height of 1 m. The seed roll is spread on the surface of finished soil, soil coverage is performed with depth of 1 cm, and irrigating is performed after soil coverage; sowing is selected in the rainy season in areas without irrigation conditions, waiting for precipitation is performed after sowing, and the soil surface is covered with non-woven fabric. Harvesting and sowing of the Stipa plant seeds in a large area are made possible, the problems that the Stipa plant seeds are intolerant to drought at seedling stage, the seedling protection rate is low and the like in production practice are solved, and technical guarantee forrestoration of degraded Stipa steppe is provided.

Description

technical field [0001] The invention belongs to the technical field of restoration of degraded grassland vegetation, and in particular relates to a method for making seed rolls of Stipa plants and a method for sowing seed rolls. Background technique [0002] At present, 90% of the grasslands in my country are degraded to varying degrees, and more than 60% of them are severely degraded. Therefore, the restoration of degraded grasslands or reclaimed natural grasslands is a major problem that needs to be solved urgently. The selection and sowing method of grass species for natural grassland restoration play a vital role in the restoration effect. In grassland vegetation restoration, due to the lack of grass species suitable for local planting, many vegetation restoration measures have not achieved the desired effect; some restoration measures have selected some vegetation that requires a lot of water as restoration grass species for degraded grasslands, resulting in Poor plant...
