Protected raising method for Astragalus membranaceus seedlings using peat and vermiculite as substrates

Abstract

The invention belongs to the technical field of traditional Chinese medicine seedling cultivation, and discloses a protected raising method for Astragalus membranaceus seedlings using peat and vermiculite as substrates; the method includes calculating peat before unpacking in spring, adding vermiculite with equal volume after the peat is smashed, and applying a full-element composite slow-releasefertilizer; leveling the ground in a greenhouse, making ridges, and fixing ridge surfaces; pressing seeding ditches during seeding, sowing Astragalus membranaceus seeds, raking flat after seeding, andspraying enough water; carrying out daily management; removing beautifying planting bags in autumn, and digging with an iron fork from either side. According to the method, seeding is performed in advance through the warm-light effect of the greenhouse in autumn, winter and spring; compared with traditional open-land seedling raising methods for high-altitude cold regions, the method allows the seedling raising period to be shortened by half a year to one year, seedling yield to be increased by three times, first-level seedling rate to be increased by 60%, root rot rate to be decreased by 100%, and digging labor cost to be saved by 66.7%; the quality of the Astragalus membranaceus seedlings is improved, the pathogen infection sources are effectively controlled and prevented, and the supply bottleneck of Astragalus membranaceus seedlings in field production is solved.

Description

technical field [0001] The invention belongs to the technical field of raising seedlings of traditional Chinese medicinal materials, and in particular relates to a method for raising seedlings of Astragalus using peat and vermiculite as substrates. 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 effec...

AI Technical Summary

Problems solved by technology

[0003] At present, in areas above 1,500 meters above sea level, the traditional astragalus seedling raising method in the open field cannot be used in the same year, and the seedling raising cycle needs 2 years, which is a long seedling raising cycle; when using the traditional pastoral soil facility seedling raising method, the high-quality (first-class seedling) rate is only 10%; and Due to the deep root system of Astragalus seedlings, the traditional open field or facility seedling cultivation methods have compact soil, difficult excavation, high damage rate, and high labor costs

[0004] To sum up, the existing problems in the prior art are: (1) the growth of the traditional astragalus seedlings in the open field in the high altitude area is not up to the standard, and the seedling cycle is long

[0005] (2) The traditional pastoral soil facility seedling raising method has a low rate of high-quality seedlings, difficult excavation, high damage rate caused by excavation, and high labor costs

[0007] 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
