Description

Germination accelerating method for radix peucedani before planting Technical Field The application relates to the technical field of Chinese medicinal material planting, in particular to a germination accelerating method for radix peucedani before planting. Background Radix peucedani is used as an important common bulk Chinese medicinal material, and root segments are generally adopted for asexual propagation in the planting process. In practical production environments, particularly in mountain areas and hilly areas with complex geological structures and prominent seasonal drought phenomena, the direct implantation of non-germinated seed root sections into fields faces multiple challenges. These challenges are presented by inconsistent germination time of the seed roots, uneven field emergence distribution, reduced overall survival ability of seedlings, difficulty in adapting to changeable soil and climate conditions, forced extension of growth cycle, influence on planting efficiency and economic benefit, and obviously insufficient resistance of newly-grown seedlings to external adverse conditions such as water shortage, temperature fluctuation and the like, and easy initiation of large-scale growth disorder. Although the peucedanum root plays an important role in agricultural economy, a pretreatment scheme aiming at the root body characteristics of the peucedanum root seeds and capable of systematically enhancing the adaptability of the peucedanum root seeds after transplanting under drought conditions is not formed in the prior art system, so that the stability of the planting process is poor and the resource waste is serious. In view of the above, there is a need in the art for improvements. Disclosure of Invention The application aims to provide a root germination accelerating method for peucedanum praeruptorum dunn, which has the advantages of improving the germination consistency and germination rate of the roots, enhancing the adaptability of seedlings under drought conditions, shortening the growth period and improving the planting efficiency and economic benefit.
