Embodiment 1

[0037] This embodiment provides a method for planting Radix Astragali in alpine regions, the steps are as follows:

[0038] Step 1, land consolidation: select sandy loam with loose soil; the organic matter content of sandy loam is 1 to 3%, and the soil pH value is 7 to 8.5; deep loose soil, use compound fertilizer as base fertilizer for deep plowing in the deep plowing process, The mixed fertilizer is composed of the core layer of trace elements, the middle layer of compound bacteria agent and the outer layer of quick-acting fertilizer; the mass ratio of the core layer of trace elements, the middle layer of compound bacteria agent and the outer layer of quick-acting fertilizer is 1~2:3~5:2~4 ; The amount of compound fertilizer used as base fertilizer is 60-90g / m 2 , and then carry out machine ditching, the ridge distance of the ditching is 65cm, and the depth of the ditch on the Longshang is 8-10cm;

[0039] Step 2. Seedling excavation: In early October in autumn, when the ni...

Embodiment 2

[0050] The present embodiment provides a kind of preparation method of the compound fertilizer used in embodiment 1, comprises the steps:

[0051] Step 1. Preparation of trace element core layer:

[0052] Pass attapulgite through a 120-mesh sieve to obtain attapulgite powder for later use, dissolve boric acid, manganese sulfate, zinc sulfate, sodium molybdate, copper sulfate, cobalt chloride and citric acid in water and mix and stir to obtain a mixed solution, and attapulgite Powder is added in the mixed solution and stirred evenly to obtain trace element feed liquid, containing boric acid 6.2mg / L, manganese sulfate 22.3mg / L, zinc sulfate 8.6mg / L, sodium molybdate 0.25mg / L, sulfuric acid Copper 0.025mg / L, cobalt chloride 0.025mg / L; The mass ratio of each trace element raw material, citric acid and attapulgite powder is 1:1:20, and described trace element material liquid is dried and processed to make its moisture content drop to 20 to 30%, the obtained trace element material ...

Embodiment 3

[0065] According to the method for planting Astragali in the alpine region provided by Example 1, the planting of Astragalus is carried out in the Chinese herbal medicine planting demonstration zone, Guofu Town, Baiquan County, Qiqihar, Heilongjiang Province, and the specific steps are as follows:

[0066] Step 1, land consolidation: select sandy loam with loose soil; the organic matter content of sandy loam is 1.24%, and the soil pH value is 7 to 8.5; deeply loosen the soil, use compound fertilizer as base fertilizer for deep plowing in the deep plowing process, compound fertilizer It is composed of the core layer of trace elements, the middle layer of compound bacteria agent and the outer layer of quick-acting fertilizer; the mass ratio of the core layer of trace elements, the middle layer of compound bacteria agent and the outer layer of quick-acting fertilizer is 1:3:2; the fertilization of compound fertilizer as base fertilizer The amount is 80g / m 2 , and then carry out m...

Abstract

The invention relates to a method for transplanting radix astragali in an alpine region, belongs to the technical field of traditional Chinese medicinal material planting methods. In order to solve the problems that the green returning rate of autumn sowing is low and new shoots grow slowly in an existing artificial radix astragali planting technology, the invention provides a method for transplanting radix astragali in an alpine region. The method comprises the steps of utilizing a compound fertilizer as a base fertilizer in a deep ploughing process of soil; manually digging radix astragali seedlings when the surface temperature at night in autumn is -4+/-1 DEG C for at least 3 consecutive days; obliquely placing the radix astragali seedlings into ditches at a certain angle by adopting azigzag mode; and after the radix astragali returns green, spraying a humic acid foliar fertilizer in a rapid growth period and when the heights of the seedlings are 10-12 cm. According to the method,the digging time, treatment time and transplanting time of the radix astragali seedlings are strictly controlled, the quality and nutrients of the radix astragali seedlings are ensured, the green returning rate of the radix astragali in the next spring is increased, high green returning rate of the radix astragali is achieved, the survival rate and growth speed of the seedlings are ensured, and the yield and quality of the radix astragali are improved.

Description

technical field [0001] The invention belongs to the technical field of planting methods of traditional Chinese medicinal materials, and in particular relates to a planting method of Astragalus membranaceus in alpine regions. Background technique [0002] Astragalus is the dried root of the leguminous plant Astragalus mongolica or Astragalus membranaceus, and is one of the commonly used Chinese medicinal materials. Astragalus is a deep-rooted plant, suitable for growing in sandy soil with deep soil, fertile, loose, and good drainage; it likes cool climate, strong drought resistance; cold-resistant, afraid of heat and waterlogging; too high temperature often inhibits growth; Humidity often causes root rot; the seed coat is relatively hard, and germination does not like high temperature. When the local temperature is 7-8°C, the soil maintains a certain humidity. Generally, seedlings can emerge in 1-2 weeks, and the optimum temperature for germination is 14-15°C. [0003] In re...
