Description

Stipa seed collecting net and method for collecting and sowing Stipa seeds

technical field

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

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.

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 Stipa steppe. Due to its strong adaptability and ability to survive in various environments, Stipa can be used as the preferred grass species for vegetation restoration of degraded grassland or abandoned grassland after reclamation. 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 It makes it more difficult for us to use native vegetation for ecological restoration. Therefore, the present invention aims to solve the harvesting and sowing problems of stipa seeds, and provide technical guidance for the restoration of degraded grassland vegetation.

Contents of the invention

The present invention is achieved through the following technical solutions: a Stipa seed collection net, which is a mesh-shaped seed sticky net woven from a plurality of thick wool threads, and has short hairs on the woolen yarns of the woven seed sticky net.

The seed sticky net is a square seed sticky net or a rectangular seed sticky net with an area of 1m ² -2m ² . Thick woolen yarn is woolen yarn with a diameter of 1 mm, with short hairs with a length of 0.5 cm to 1 cm on the woolen yarn. The mesh of the seed sticking net is a square mesh with a side length of 2mm.

A method for collecting and sowing Stipa seeds, comprising the following steps: a. Seed collection: dragging the Stipa seed collection net on the grassland during the full bloom stage of the Stipa seeds, utilizing the longer awns of the Stipa seeds and the Stipa seeds The physical interaction between the hard spines at the bottom and the short hairs of the seed sticking net collects the seeds, and most of the stipa seeds in the dragged places hang on the stipa seed collection net until the collected seeds reach the desired density Finally, stop dragging; if the number of seeds sticking to the collection net of Stipa seeds is less, then use the other side of the seed sticking net to drag on the grass, so that there are more positive and negative sides of the seed sticking net. Seeds, thereby improving the sowing efficiency, because the two-sided structure of the seed sticking net is the same, so the seeds can be continued to stick on the other side when one side is almost sticky; b, making seeding strips: the seeds after the seed collection step Cut the sticky net into a sowing strip with a width of 1cm to 1.5cm; c. Sowing: Then use a ditch opener to open the ditch, put the cut sowing strip in the opened ditch, and then cover the sowing strip with soil , the sowing depth is 2cm to 3cm, and the sowing width of the sowing bar in step c is determined according to the density and quantity of Stipa seeds on the seed sticking net.

The beneficial effects of the present invention are: the present invention is mainly applied to the restoration of degraded grassland vegetation, and the Stipa seed collection net and the Stipa seed collection and sowing method in the present invention can effectively provide local excellent grass species for the restoration of degraded grassland vegetation, with the advantages of The recovery effect is good and the process is simple. The invention relates to a method for collecting stipa seeds on natural grasslands, and a method for sowing restoration on degraded grasslands or reclaimed grasslands by using the collected stipa seeds. Through the sowing method disclosed in the present invention, Stipa seeds can be collected more conveniently, and the step of removing Stipa seeds is omitted, and the problem of difficult sowing is solved, and the harvesting and sowing process of Stipa seeds is directly realized, The intermediate link is reduced, and the purpose of restoring degraded grassland by native vegetation can be realized.

The invention also solves the following technical problems: 1) difficult problems such as collection, awning, and sowing of Stipa seeds in natural grasslands; 2) Realizing direct sowing with awns after seeds are harvested; 3) Reduced the physical damage probability of Stipa seeds to livestock ; 4) Turning stipa seeds from "waste" to "treasure" provides high-quality local materials for the restoration of degraded grassland ecological vegetation, and improves the success rate of degraded grassland restoration.
