Cultivation method for selenium-enriched pueraria lobata

Abstract

The invention discloses a cultivation method for selenium-enriched pueraria lobata. The cultivation method for the selenium-enriched pueraria lobata comprises the following steps: excavating puerarialobata; cutting off from the top to the bottom of the pueraria lobata and keeping the pueraria lobata 8-15cm long to obtain vegetative seedlings; pruning the obtained vegetative seedlings, and keeping1 to 2 vine buds which are strong in roots, then soaking in a soaking solution for 1 to 5 hours and draining to be planted; from June to July during which the pueraria lobata is planted, pruned and subjected to root thinning, spraying 20 to 35ml of a nutrient solution per plant for the first time; spraying 40 to 55ml of the nutrient solution per plant for the second time from August to Septemberduring which tubers of the pueraria lobata are rapidly increased, spraying 15 to 30ml of the nutrient solution per plant for the third time in October. The cultivation method for the selenium-enrichedpueraria lobata disclosed by the invention has the beneficial effects that compared with the traditional seed, cutting and layering cultivation method, the used seedlings further can provide more nutrient supply for pueraria lobata seedlings and can promote the pueraria lobata seedlings to grow healthily even in the case of insufficient fertility, so that the survival rate of the pueraria lobatacultivation is improved.

Description

Technical field [0001] The invention relates to the field of agricultural planting, in particular to a selenium-enriched kudzu root cultivation method. Background technique [0002] Pueraria lobata (Willd.) Ohwi is a perennial vine deciduous plant belonging to the leguminous Papilionaceae subfamily, also known as dried Pueraria lobata, Pueraria lobata, etc., known as "Northern Ginseng, Southern Pueraria" and "Asian Ginseng" The medicinal and food homologous plant approved by the Ministry of Health of the People’s Republic of China.

Problems solved by technology

[0005] After consulting the literature, it is found that the patent application CN103650850A is about the cultivation method of selenium-enriched kudzu root, but the application patent CN103650850A mainly applies exogenous selenium fertilizer: agricultural selenium fertilizer, sodium selenite, selenium rich treasure or selenium-enriched amino acid foliar fertilizer, a On the one hand, the absorption and utilization rate of exogenous selenium fertilizer by plants is not high; on the other hand, the exogenous selenium fertilizer applied, such as sodium selenite, is a highly toxic substance with high cost, which will cause poisonous damage to laborers working in the farmland and cause environmental pollution.
