[Effects of Different Planting Direction and Layer Combination on Gastrodia elata f. elata in Bionic Wild
Objective:
Combination of different planting direction and layer were set to choose the best technology of cultivation of Gastrodia elata f. elata.
Methods:
To improve the yield and quality of Gastrodia elata f. elata, randomized block design experiments were carried out to investigate the yield and quality, and to analyze their economic effectiveness in bionic wild cultivation.
Results:
Length, width, thickness and weight of southern direction's Gastrodia elata f. elata developed better than the northeast direction. The three planting layer levels on growth effect of Gastrodia elata f. elata was the 3rd layer > the 2nd layer > the 1st layer. In six treatments, combination of southern direction-the 3rd layer was the best technology of cultivation of Gastrodia elata f. elata, which had the best growth condition, the highest yield significantly higher than other treatments, and the best economic benefits.
Conclusion:
Southern direction associated with the 3rd layer is the best combination to planting Gastrodia elata f. elata in bionic wild cultivation. The planting ways not only improve the yield and quality, but also save land.
