The Effects of Cultivation Conditions on the Growth of Morchella by ANN Model

Abstract

Morchella is favored for its distinctive taste and rich nutritional value, yet the traditional cultivation methods are often limited by the natural environment. The effect of different culture conditions on mycelial growth of Morchella was studied by comparative experiment. The results showed that the best soil for Morchella growth was soybean soil, the best soil depth was 2 cm, and the best soil humidity was 80%. The optimal culture condition after orthogonal experiment was soybean soil with soil depth of 2 cm and humidity of 70%. The results of correlation analysis showed that the mycelia of Morchella was most affected by soil type and least affected by soil humidity. The relationship between different culture conditions and mycelial growth of Morchella was studied by neural network model, and its R2 reached 0.995, so as to explore more cultivation management strategies and provide more comprehensive and scientific guidance for its artificial cultivation.
