Abstract
The invention relates to the technical field of agriculture, and discloses a traditional Chinese medicine planting method applicable to sand in a photovoltaic power station in a sand storm area. The method comprises the following steps: (1) Ridging the sand in the region where the photovoltaic power station is located to form a sand ridge region and a planting region; (2) Carrying out primary mineralization on the sand ridge area, manufacturing a wind shielding wall, and then carrying out secondary mineralization and tertiary mineralization on the sand ridge area only; (3) Mineralizing the planting area for the fourth time, including spraying a soil conditioner and a mineralizer; (4) Seedling culturing is carried out on the notopterygium root seeds and the rhodiola rosea seeds respectively, and then transplanting is carried out on the notopterygium root seeds and the rhodiola rosea seeds respectively in the planting areas. The mineralization intensity of the sand ridge area is improved by mineralizing the sand ridge area for a plurality of times, so that the mineralization intensity of sand soil is ensured, a higher consolidation degree is formed, and the shear strength of soil is increased; soil conditioner and mineralizer are added into the planting area to reduce the mobility of sand in the planting area, improve water retention capacity and increase the survival rate of plants.
Description
Technical Field
The invention relates to the technical field of agriculture, in particular to a traditional Chinese medicine planting method applicable to sand in a photovoltaic power station in a sand wind area.
Background
The photovoltaic power generation is a clean and sustainable power generation way, and has good energy conservation and emission reduction benefits. The light Fu Banji occupies large land area, the land is relatively barren, the sunlight is lack to direct, and the water resource is lack, so that the land with large area is still in a vacant waste state.
The Notopterygium forbesii is a pteridophyte growing in Qinghai province, can grow in cold, thin, barren and poor soil environments, mostly grows in mountain areas, is loved in yin, has stronger drought resistance, has the reputation of 'first rhizome under the sky', has high drug effect, and can be used for treating symptoms such as rheumatism, neuralgia, headache and the like. The rhodiola rosea is a very cold-resistant plant, is a tunnel medicinal material of the Qinghai, has the characteristics of dry soil, more sand, less water and less fertilizer, has high medicinal value in the field of traditional Chinese medicine, is known as magic grass, and can be used for treating hypoxia, cardiovascular and cerebrovascular diseases, liver and lung diseases, immunoregulation and the like.
Therefore, how to repair the ecological environment of the photovoltaic power station in the sand-blown area and realize reasonable planting of the traditional Chinese medicinal materials, so that the survival rate of the traditional Chinese medicinal materials is improved, and the technical problem to be solved in the field is urgent.
Disclosure of Invention
In view of the above, the invention provides a planting method of traditional Chinese medicines in the sandy land of a photovoltaic power station in a sandy region, which can not only improve the mineralization strength of sandy soil, but also improve the survival rate of traditional Chinese medicines; compared with direct planting, the survival rate of the notopterygium root and the rhodiola rosea is improved by 45% -60%.
In a first aspect, the invention provides a method for planting traditional Chinese medicines in a sand of a photovoltaic power station in a sand wind area, which comprises the following steps:
(1) Ridging the sand in the region where the photovoltaic power station is located to form a sand ridge region and a planting region;
(2) Manufacturing a wind shielding wall after the sand ridge area is mineralized for the first time, and then mineralizing the sand ridge area for the second time and the third time;
(3) Mineralizing the planting area for the fourth time, including sowing a soil conditioner and spraying a mineralizer; the soil conditioner comprises tortoise shell residue powder, graphene and fermentation mixed materials; at least one of humic acid, nano silver and silicate is also included; the mineralizer is a second carbonate mineralized bacteria liquid;
(4) And respectively transplanting the notopterygium root seeds and the rhodiola rosea seeds into the planting area.
In an alternative embodiment, the first mineralization, the second mineralization, and the third mineralization each comprise: spraying the first calcium salt solution, the first carbonate mineralized bacteria liquid and the first cementing liquid in sequence.
In an alternative embodiment, the OD of the first carbonate mineralization bacterial liquid 600 =1 to 3, the addition amount is 0.4L/m 2 ~1.5 L/m 2 。
In an alternative embodiment, the concentration of the first calcium salt solution is 0.02M-0.06M, and the adding amount is 0.4L/M 2 ~1.0 L/m 2 The method comprises the steps of carrying out a first treatment on the surface of the The calcium salt is at least one of calcium chloride, calcium nitrate and calcium hydrophosphate; the first calcium salt solution has lower concentration, plays a role in fixing cells, and has no mineralization effect.
In an alternative embodiment, the first cementing liquid contains 0.5M to 1M urea and 0.5M to 1M calcium chloride, and the molar ratio of the calcium chloride to the urea in the first cementing liquid is 1: 1-1.5, wherein the addition amount of the first cementing liquid is 1L/m 2 ~1.8 L/m 2 。
In an alternative embodiment, the first carbonate mineralizer is selected from at least one of bacillus pastoris, bacillus mucilaginosus, bacillus cereus, pseudomonas stutzeri.
