Example Embodiment

[0042] Example 1

[0043] It includes the following steps:

[0044] 1. Collection of Apocynum venetum root segment:

[0045]Taking into account the adaptability of plants, this embodiment takes apocynum venetum roots that grow wild in the west of Jilin Province as the collection object. In the protected growing areas of wild Apocynum venetum, the best time to collect the roots of Apocynum venetum is before June 10, just before the local Apocynum venetum turned green. When digging the roots of Apocynum venetum, use interlaced digging or small patchy digging, take a part and keep a part, and be careful not to excavate extinctly. The digging depth is appropriate to dig up to the horizontal root, generally the depth is 20-30cm.

[0046] Generally, the longer the root length of Apocynum venetum, the higher the seedling rate, but the smaller the number of roots, the lower the reproduction coefficient; the shorter the root, the lower the seedling rate, but the more the number of roots an...

[0064] Example 2

[0065] Step 1: Collection of Apocynum venetum root segment, Step 2: Treatment of Apocynum venetum root segment, Step 3: Preparation of seedling cultivation soil, Step 4: Preparation of seedling bed, same as Example 1,

[0066] Five, land preparation

[0067] ①Plot selection: Choose soil with a pH value of 9.5~10.2 in 0~30cm soil; ②Weeding: After the plot selection, use glyphosate or other destructive herbicides for destructive weeding, and carry out soil tillage after 14 days; ③Rake and rearrangement: Apocynum venetum is a root bushy plant, and it likes to grow on loose and well-ventilated soil. Therefore, when planting Apocynum venetum, the soil should be turned, raked, and ground preparation, so that the land is leveled and the soil is finely broken; ④Ridging: ridged at 50cm ridge spacing, and ridge height is 18cm. Water movement in saline-alkali land due to the influence of micro-topography. The salinity content in ridges and furrows is often lower than that ...

[0075] Five, land preparation

[0076] ①Plot selection: choose soil with a pH value of 11.0 in the soil of 0~30cm; ②Weeding: After plot selection, use glyphosate or other sterilizing herbicides for sterile weeding, and carry out soil tillage after 14 days; Tidying up: Apocynum venetum is a bushy root plant, which likes to grow on loose and aerated soil. Therefore, when planting Apocynum venetum, the soil should be turned, raked, and ground preparation, so that the land is leveled and the soil is finely broken; ④Ridging: ridged at 40cm ridge spacing, and ridge height is 20cm. Water movement in saline-alkali land due to the influence of micro-topography. The salinity content in ridges and furrows is often lower than that of ridge moss, and the soil...

Abstract

The invention relates to a method for using apocynum paper cylinder cultivation technique to recover the plant at alkaline land. Wherein, it comprises that collecting apocynum root, treating the apocynum root, preparing cultivation soil, preparing seed bed, finishing land, transplanting, and managing field. The invention has the advantages that artificially planting the apocynum on alkaline land, to improve the ecologic environment.

Description

technical field [0001] The invention belongs to a method for restoring saline-alkali land vegetation by using the rapid propagation technology of apocynum root segments. Background technique [0002] The production practice of saline-alkali land treatment in recent years shows that "biological alkali control" is an effective method for saline-alkali land treatment, which is in line with the natural conditions in the west of Jilin Province and the production level and life style of farmers and herdsmen. People have greatly improved the ecological environment of the treatment area through biological measures such as "enclosing with fences and planting saline-alkali-tolerant plants". However, people have gradually realized in the process of saline-alkali land treatment that the saline-alkali land treatment in western Jilin Province must fully consider people's livelihood, life and economic interests, and that ecological benefits should be combined with economic benefits, otherw...
