Problems solved by technology

my country's saline-alkali land has been gradually recognized and developed by people, but the degree of development is limited, and many crops cannot be effectively planted in saline-alkali land
[0003] At present, many coastal saline-alkali lands are used to grow various saline-alkali-tolerant crops, but there are many obstacles to the cultivation of common crops, making it difficult to grow effectively
The grain amaranth has a certain ability of salt-alkali tolerance, but the salt-tolerant ability is limited; while Coptis chinensis is planted in saline-alkali soil, it can hardly grow normally. Coptis chinensis has high medicinal value and economic value
[0004] The planting of grain amaranth and Coptis chinensis in the prior art has the following defects: (1) The survival rate of grain amaranth planting is not high enough, and the yield is not high; (2) The survival rate of Coptis chinensis planted in saline-alkali soil is very low; (3) It is difficult to do it in the existing technology To improve the saline-alkali land while planting grain amaranth and coptis

Embodiment 1

[0024] Example 1 Interplanting method of grain amaranth and coptis in a kind of saline-alkali land

[0025] Step 1. Select the saline-alkali land in the planting area

[0026] Saline-alkali land in the selected planting area: the salt content of the 0-30cm soil layer is 0.56-0.58%, the pH is 8.0-8.2, the humus content is 0.2-0.4g / kg, the total potassium content is less than 0.2%, and the total soil porosity is 29-31 %, the soil bulk density is 1.9-2.3g / cm 3 .

[0027] Step 2. Preparation before planting

[0028] (1) Preparation of decomposing agent

[0029] a. Activate and expand the strains of Streptococcus faecalis, Bifidobacterium adolescentis, Trichoderma reesei, and Rhodobacter nitrogen-fixing respectively. The culture solution is centrifuged and the bacteria residue is separated to obtain a bacterial suspension, and the bacterial suspension is combined and evenly distributed. Spray on starch to obtain composite microbial powder;

[0030] The content of bacteri...

Embodiment 1

[0055] Adopt the planting method of embodiment 1, only change the planting steps, change the planting steps to: plant Coptis chinensis only, the planting distance is 40cm, and the row spacing is 40cm; other planting methods are carried out according to the method of embodiment 1.

Embodiment 2

[0057]Adopt the planting method of embodiment 1, only change the planting step, the planting step is changed into: only plant grain amaranth, the planting distance is 20cm, and the row spacing is 30cm; Other planting methods are carried out by the method for embodiment 1.

[0058] Planting results:

[0059] (1) Adopt the present invention to interplant grain amaranth and Coptis chinensis in saline-alkali land for 5 years, and record the planting results:

[0060] Grain amaranth: the planting survival rate is high, the yield is high, and the nutritional value is high; the average annual planting survival rate is 98%, the mature grain amaranth harvested is tender and juicy, and the average annual green fodder is 20 tons per mu. Compared with Comparative Example 2: The survival rate increased by 16%, and the average yield per mu increased by 13%;

[0061] Coptidis: high planting survival rate and high yield; the planting survival rate is 89.2%. It begins to bloom and bear frui...

Abstract

The invention provides a method for interplanting grain amaranth and coptis chinensis in a saline and alkaline land. The method comprises the steps of preparation before planting, planting, watering and management. In the planting step, the interplanting proportion of the grain amaranth to the coptis chinensis is 3:4, ridge culture is adopted for the grain amaranth, and trench culture is adopted for the coptis chinensis. The planting step includes coptis chinensis planting, and for the coptis chinensis planting, the row spacing is 40 cm, the line spacing is 40 cm, and four lines of coptis chinensis are planted in each rectangular piece of the land. The planting step further includes grain amaranth sowing, and for the grain amaranth sowing, the row spacing is 20 cm, the line spacing is 30 cm, and three lines of grain amaranth are planted in each ridge. The grain amaranth and the coptis chinensis are interplanted by means of the method, the survival rate of the grain amaranth planted in the saline and alkaline land is 98%, and the survival rate of the planted coptis chinensis is 89.2%.

Description

technical field [0001] The invention belongs to the field of planting methods in saline-alkali soil, and relates to a method for interplanting plants in saline-alkali soil, in particular to a method for interplanting grain amaranth and coptis in saline-alkali soil. Background technique [0002] The area of ​​saline-alkali land in the world is about 955 million hm 2 , the area of ​​saline-alkali land in my country is about 9.91×107hm 2 , of which the total area of ​​coastal tidal flats is about 2.35 million hm 2 . my country's saline-alkali land has been gradually recognized and developed by people, but the degree of development is limited, and many crops cannot be effectively planted in saline-alkali land. [0003] At present, many coastal saline-alkali lands are used to grow various saline-alkali-tolerant crops, but there are many obstacles to the cultivation of common crops, making it difficult to grow them effectively. Grain amaranth has a certain ability to tolerate ...
