[ Objective) This paper aimed to the quantification of the detailed ranges and dynamics of the environmental factors of the light, temperature, air and moisture in morel cultivation. ( Methods ] Environmental factors in greenhouses for Morchella importuna cultivation were collected in Chengdu plain area using Internet of Things (IoT) technologies. Illumination intensity, air temperature, air relative humidity, oxygen percentage in the air, carbon dioxide concentration in the air, soil temperature and soil water content were recorded every ten mi nutes, in greenhouses with different layers of sunshade-net. Fluctuation models in 24-hour cycle were established for the environmental fac tors at different stages. [ Results] The sunlight in the greenhouses showed a dynamic that indirectly regulated the fluctuating features of the ox Oxygen percentage, relative humidity and temperature in the air, while the average illumination intensity in the greenhouse with the highest mo rel yield were about 2500 - 3500 ks at the noon of sunny days. Sunshade-net effectively prevented over-heating during daytime and over-chill ing during night., diminishing the occurrence of extreme values of air temperature and soil temperature, whereas the cumulative temperatures of the air and the soil, as well as the cumulative values of the relative humidity. oxygen percentage and carbon dioxide concentration in the air, and the soil water content, showed no significant difference between the regimes of different sunshade net layers. The effects of the sunshade-net layers were attenus ting the fluctuations of the environmental factors, The air tem perature was either higher than or similar to the soil temperature during the fruiting stage. (Conclusion) Field conditions ideal for morel cultivation were summarized from the analytical results of the environmental factors, for the reference of field management of morel cul tivation in plain area of southwestern China, which further provided some inspirations for the engineers hoping to develop factory-mode tech nologies of morel production.

【Objective】The present paper aimed to implement the utilization of rice-straw resource, and to provide more scientific foundations as well as technical guarantees for the upgrading of the current Pleurotus ostreatus cultivating industry prevailed by conventional agricultural-practices. 【Method】This study used P. ostreatus as test material, and used substitutional cultivating methods to compare the growth of 10 commonly-used P. ostreatus strains on a substrate with high rice-straw content. Meanwhile, based on determination of the nutrients in the cultivation materials, formulations of carbon-and nitrogen-sources as well as the optimal particle size of rice straw of the cultivation substrates were optimized using the optimal P. ostreatus strains screened out.【Result】The results showed that rice straw contained more nitrogen, phosphorus, soluble sugar, total protein, free amino acids and other nutrients as well as less lignin compared to cottonseed hulls and corn cobs. Wheat bran had the most comprehensive and balanced nutrition. On the substrate with high rice-straw content, the mycelium of strain S1 had the fastest growth rate, the highest biological efficiency and the best agronomic traits. The largest pileus diameter was obtained on the substrate particle size of F4. Mycelium grown on the substrate with particle size F5 had the fastest growth rate and a good biological efficiency. Rapeseed cake, wheat bran, corn flour, and urea all showed impacts on the C:N ratio of thecultivation substrate, with a growing order. The formula N8 of nitrogen source had the shortest time of the mycelium colonizing the entire cultivating bag and the highest yield per bag. With an increase of rice straw proportion, the cultivation cost was gradually reduced. The formula C3 and C4 had the highest total income of and single-bag profit. The production/investment ratio of C4 was the highest. 【Conclusion】Rice straw is rich in nutrients and is suitable for cultivating P. ostreatus. The most suitable strain is ’Za you No.1’. The optimal particle size is chopped segments in 30 mm length or fine-crushed filaments screened through a sieve with 20 mm diameter holes. The optimal formula of carbon-and nitrogen-sources is 61.5 % of rice straw, 21.5 % of cottonseed hull, 15 % of corn flour, and 2 % of lime. [ABSTRACT FROM AUTHOR]

Teadust, the tea leaf after tea-polyphenol extraction were used to replace traditional materials for spp. Cultivation in the present study. Six formulae were developed，and the fruiting rate on each formula was tested. The resialts showed that tlie Formula-4 (contai­ning 50 % teadust) could offer the highest yield (0.733 kg/bag) in the mushroom production, higher by 0.269 kg/bag in comparison with the CK (0.464 kg/bag). Meanwhile, the highest biological efficiency (97.69%) was achieved by the Formula-4, higher by 23.45 % compared with the CK (74.24%). The profits of cultivation for fresh mushroom (0.72 yuan/bag) reached the highest level，higher by 0.67 yuan/bag than the CK (0.05 yuan/bag). The fruiting bodies produced by this formula contained tea-polyphenol. We believe that using the Formulation-4 with the key ingredient of 50 % teadust can result in a better economic efficiency，and can be used in the demonstration of Pleurotus spp. production.

In order to study the content and species of bacterium inside and outside culture room, in the main Auricularia polytricha plantation of Sichuan province, the bacterium content in air was tested inside and outside culture room in 24 hours at the time of inoculating. Correlation analysis of bacterium content in air with temperature and humidity showed that the latter was the main factor. And the period of minimum bacterium content was from 1:00 to 5:00. Identification of bacterium showed that most of them were Bacillus. The results showed that content of bacterium inside and outside culture room with strong timeliness, and most of them were Bacillus . [ABSTRACT FROM AUTHOR]
