Stipa capillata seed collecting net and stipa capillata seed collecting and sowing method

Abstract

The invention discloses a stipa capillata seed collecting net and a stipa capillata seed collecting and sowing method. The stipa capillata seed collecting net is a reticular seed sticking net woven from multiple thick woolen yarns, and each woolen yarn used for weaving the seed sticking net is provided with short downs. The sowing method comprises the following steps: dragging the stipa capillata seed collecting net on grassland in a full-bloom stage of stipa capillata seeds, collecting the seeds by utilizing physical effect between longer awns of the stipa capillata seeds and hard thorns at the bottoms of the stipa capillata seeds as well as the short downs of the seed sticking net, if quantity of the seeds is low, then dragging the back of the sticking net, and stopping dragging until density of the collected seeds reach the required quantity; cutting the seed sticking net after the seed collecting step into sowing strips with the width of 1-1.5cm; and putting the cut sowing strips into opened furrows, and then covering the sowing strips with soil. The sowing method has the advantages that direct sowing with the awns is realized after the seeds are harvested, physical damage probability of the stipa capillata seeds on livestock is reduced, and a high-quality native material is provided for ecological vegetation restoration of degraded grassland.

Description

technical field [0001] The invention belongs to the technical field of degraded grassland vegetation restoration, and in particular relates to a net for collecting stipa seeds and a method for collecting and sowing stipa seeds. Background technique [0002] At present, my country's natural grasslands have been degraded to varying degrees. With the implementation of national policies such as banning grazing and resting grazing, returning farmland to forests and grasslands, we need to restore degraded grasslands or reclaimed natural grasslands. The selection of grass species for natural grassland restoration and The seeding method plays a crucial key role in the restoration effect. [0003] Stipa spp. plants are the main dominant species and constructive species in the Eurasian steppe (Steppe), and a series of alternative distributions have been produced along the geographical hydrothermal gradient and microenvironmental changes, forming a unique and type Diverse Eurasian Stip...

Problems solved by technology

However, it has been generally believed that Stipa plants are harmful weeds for a long time, and the increase in the number of Stipa will significantly reduce the quality of the grassland. In addition, it is difficult to harvest and process Stipa seeds, so there is no Stipa seeds for sale so far on the market, which means makes it difficult for us to use native vegetation for ecological restoration
