Embodiment 1

[0043] Include the following steps:

[0044] 1. Collection of Apocynum root:

[0045]Considering the adaptability of plants, this embodiment takes the root system of Apocynum apocynum growing wild in the west of Jilin Province as the collection object. In the protected wild apocynum growing areas, it is advisable to collect the roots of apocynum before June 10, when the local apocynum turns green. When digging the roots of apocynum, use interlaced digging or small patch digging, take a part and keep a part, and be careful not to excavate extinctly. The excavation depth is advisable to excavate to the horizontal root, and the general depth is 20-30cm.

[0046] Generally, the longer the root section of apocynum is, the higher the seedling rate is, but the number of root sections obtained is small and the reproduction coefficient is low; the shorter the root section, the seedling rate is lower, but the number of root sections obtained is large and the reproduction coefficient i...

Embodiment 2

[0065] The collection of step one apocynum root section, the processing of step two apocynum root section, the preparation of step three seedling soil, step four seedbed preparation, same as embodiment 1,

[0066] Five, land preparation

[0067] ①Site selection: choose soil with a pH value of 9.5~10.2 in 0~30cm of soil; ②Weeding: After the plot is selected, use glyphosate or other herbicides to kill weeds, and then cultivate the soil 14 days later; ③Harrowing and finishing: Apocynum is a rooting plant that likes to grow on loose and well-ventilated soil. Therefore, when planting apocynum, the soil should be turned, harrowed, and plowed to make the land level and the soil finely divided; ④ Ridge: Ridge at a distance of 50 cm, and the height of the ridge is 18 cm. Due to the water movement caused by the influence of micro-topography in saline-alkali land, the saline-alkali content in furrows is often lower than that of moss, and the soil moisture content in furrows is often hig...

Embodiment 3

[0074] The collection of step one apocynum root section, the processing of step two apocynum root section, the preparation of step three seedling soil, step four seedbed preparation, same as embodiment 1,

[0075] Five, land preparation

[0076] ①Site selection: choose soil with a pH value of 11.0 in the 0-30cm soil; ②Weeding: After the plot is selected, use glyphosate or other herbicides to kill weeds, and then cultivate the soil after 14 days; ③Hake Tidying: Apocynum is a rooting plant that likes to grow on loose and well-ventilated soil. Therefore, when planting apocynum, the soil should be turned, harrowed, and plowed to make the land level and the soil finely divided; ④ Ridge: Ridge at a distance of 40 cm, and the height of the ridge is 20 cm. Due to the water movement caused by the influence of micro-topography in saline-alkali land, the saline-alkali content in furrows is often lower than that of moss, and the soil moisture content in furrows is often higher than that ...

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...
