Problems solved by technology

[0004] (1) At present, in areas with an altitude of 1,500 meters or higher, the traditional method of raising seedlings in the open field of Astragalus has a long cycle, resulting in failure to grow seedlings in that year
[0005] (2) The traditional Astragalus facility seedling raising method, the high-quality (first-class seedling) rate is only 10%
[0006] (3) Due to the deep root system of Astragalus membranaceus seedlings, the soil is compacted by traditional methods of raising seedlings in the open field or in facilities, making digging difficult and costly
[0008] The significance of solving the above technical problems: Astragalus seedlings have a root length of 25-40cm, the traditional open-field seedling cultivation cycle is long, digging is difficult, and the rate of high-quality seedlings is low

Embodiment 1

[0041]The Chinese herbal medicine industry in Lanzhou is an emerging industry that has developed in recent years. It is a new area for planting Chinese herbal medicines in Gansu Province. In 2018, the total area reached 118,000 mu. The main planting species is Ural licorice, followed by astragalus, isatidis, and Bupleurum. , Lycium barbarum, Scutellaria baicalensis, Fangfeng, etc. Lanzhou's traditional Chinese medicine industry has problems such as poor soil, low effective rainfall, insufficient rural labor force, weak seedling production links, extensive cultivation, relatively low degree of mechanization, and high cost composition. For Astragalus membranaceus with deep roots, there is a technical bottleneck in seedling cultivation. At present, the cultivation area in Lanzhou is about 20,000 mu, 90% of Astragalus seedlings are transferred from outside, and the disease root rate is as high as 30%. This technology uses the temperature and light effect of the greenhouse in autu...

Embodiment 2

[0043] The astragalus seedlings were continuously tested for 3 years under different soil and climate conditions. Among them, in 2015, in the arid mountainous area of ​​Minle Township (2,630 meters above sea level), Yongdeng County, Lanzhou City, Gansu Province, Astragalus was treated with direct seedlings of white film, black film, open field seedlings, and germination of white film and black film. Sow on April 3, the sowing rate per mu is 25kg, and the seedlings will emerge on April 23. The seedling period is 20 days, and the emergence rate is 20-30%. Among them, the open-field seedlings for direct seeding were excavated in October of that year and planted indoors. The rhizome length was only 17.79cm, and the rhizome diameter was only 3.3mm. That is, the first-grade seedlings cannot be produced.

[0044] In 2016, in Longquan Town, Yongdeng County, Lanzhou City, Gansu Province (average altitude 1,600 meters), seedlings were raised in the open field of Sichuan water and water...

Abstract

The invention belongs to the technical field of seedling raising, and discloses a facility seedling-raising and harvesting method of Astragalus membranaceus using coconut bran as a matrix. Ridges and operation roads are laid between the ridges; when sowing, press the sowing furrow on the ridge surface with coconut bran as the matrix, and calculate the row sowing amount to sow the astragalus seeds; after sowing, use a wooden board to rake and spray enough water; carry out daily management, and move it in autumn. Use an iron fork to dig up Astragalus seedlings with a planting bag. The method adopts the temperature and light effect of autumn, winter and spring in the greenhouse, sows seeds in advance, shortens the seedling raising period from half a year to 1 year compared with the traditional open field seedling raising method in high altitude and cool areas, saves 2-3 times of irrigation compared with the traditional facility seedling raising, and increases the seedling yield by 3 times, the rate of first-class seedlings is increased by 60%, root rot is reduced by 100%, and labor costs for excavation are saved by 66.7%; the invention improves the quality of astragalus seedlings and solves the supply bottleneck of astragalus seedlings in field production.

Description

technical field [0001] The invention belongs to the technical field of seedling cultivation, and in particular relates to a method for cultivating and harvesting astragalus seedlings with coconut bran as a substrate. Background technique [0002] At present, the closest existing technology: the production link of Chinese medicinal material seedlings is weak, and the cultivation is extensive. Astragalus mainly relies on seeds for reproduction. After sowing seedlings in the first year, they are usually stored in cellars or transplanted while digging. In the second year, they are transplanted to produce medicinal materials. The yield and quality of medicinal materials depend not only on the quality of the seeds, but also on the quality of the seedlings. ; High-quality seedlings are the fundamental guarantee for improving the yield and quality of Astragalus medicinal materials, so the yield and quality of seedlings are the key to measure the effectiveness of seedling cultivation...
