Abstract: An imitation wild cultivation technique for Dictyophora indusiata has been studied in Dendrocalamus latiflorus stands in Rongchang District of Chongqing City, to promote the economy of regional forests in Chongqing, and to make sure that the project of returning farmland to forest does not rebound. The germination time, fresh weight, dry weight, and stem length of D. indusiata, and air temperature of the germination period were measured respectively. The effects of different cultivation patterns on yield and quality of the wild cultivated D.indusiata and its economic benefit were analyzed. The results showed that: ① The yield of D. indusiata had a double peak along with the growth time and temperature inside the forest was more than 35 ℃, the growth of D. indusiata was restrained. ② The optimized configuration of the key cultivation technique has been carried. The results showed that the matrix usage was the first factor affecting extremely yield of D. indusiata. The second factor was the amount of strain, and the third was forest canopy density. But the latter two factors were not significant.③ D89 was the optimal strain in D. latiflorus stands in Rongchang District of Chongqing City. The best model was that in the early march, the bacteria amount was controlled in about 5 000 kg/hm2. The different substrates was layered in different position of D. latiflorus stands. The lower layer of bamboo branches and leaves was 66 700 kg/hm2, and the upper layer of bamboo chips was 83 300 kg/hm2. Forest canopy density was controlled in 0.6. The fresh output and the net income could respectively reach 15 360 kg/hm2 and 241 890 yuan/hm2.
