Effect of cutting difference on the production of hydroponic yield of Aralia elata
The young buds of Aralia elata are delicious,sweet,fresh,mellow,and rich in wild flavor,known as the"king of mountain vegetables".However,its wild production can hardly meet market demand.Therefore,it is particularly urgent to develop a convenient,easy-to-promote,and highly operable cultivation technique for Aralia elata.This study used two types of Aralia elata spikes from the mountainous area of eastern Liaoning as test materials to explore the effects of spike varieties,stem length,and shoot diameter on the hydroponic production process and yield of Aralia elata,aiming to find suitable spike indicators for hydroponic production and thereby improve the efficiency of hydroponic production.The results showed that variety 2 began harvesting about 1.8 days earlier than variety 1.The longer the stem length,the earlier the germination time,and the germination time was relatively concentrated,resulting in earlier harvesting,longer harvesting time,and more harvesting times.Similarly,the thinner the stem,the earlier the germination time and the earlier the end of germination,with germination time being more concentrated.In addition,the single-root yield of hydroponic young buds of Aralia elata spikes reached(18.9±6.2)g,and the yield of hydroponic young buds of variety 2 was higher than that of variety 1.Specifically,when the stem length was controlled within 30~60 cm and the shoot diameter was within 10~16 mm,both the stem length and shoot diameter showed a positive correlation with the yield of hydroponic young buds.
