A kind of astragalus seedling raising method using peat and vermiculite as substrate

Abstract

The invention belongs to the technical field of seedling raising of traditional Chinese medicinal materials, and discloses a method for raising seedlings of Astragalus using peat and vermiculite as substrates. Elemental compound slow-release fertilizer; after leveling the ground in the greenhouse, pile up the ridges and fix the ridge surface; press the seeding ditch when sowing, sow the seeds of Astragalus membranaceus, rake them flat after sowing, and spray enough water; then carry out daily management; Planting bags, excavated from either side with an iron fork. The invention uses the temperature and light effect of the greenhouse in autumn, winter and spring to sow seeds in advance, shortens the seedling raising period by half a year to one year compared with the traditional method of raising seedlings in the open field in high-altitude and cool areas, increases seedling yield by 3 times, increases the rate of primary seedlings by 60%, and reduces root rot Disease 100%, saving 66.7% of labor costs for digging; the invention improves the quality of Astragalus seedlings, effectively controls and prevents the source of infection of pathogens at the same time, and solves the supply bottleneck of Astragalus seedlings in field production.

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...

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
