Bashang Alpine Areas Summer Feasibility Study For The Production Of Pleurotus Ostreatus

The climate is drought and cold in Bashang alpine areas.The crops production is lower and instability .The economics is very lag. The pappers using regional cool climate resources explores mushroom yielded under succeeful wrong season vegetables. The purpose is using regional cool climate resources advantage to yield mushroom and remote sales.Thus it can provids a technical way for regional agriculture higher grade.From July in 2007 to october in 2008 we do experiments in ZhangBei experimental station which belongs to the agriculture univercity of HeBei.It revolves and Products feasibility analysis from market researching/ habitat adaptability/ Environments regulated and comparison of production efficiency.The results were summarized as followes:1. Pleurotus ostreatus market trading volume displays peak and trough evry year.There is obvious busy-season and off-season and the price difference between busy-season and off-season is 82%～93%.The volume of transactions is steady.There is significant economic benefits yields Pleurotus ostreatus in Bashang alpine areas in summer.2. The ten-days average temprature is no more than 20℃. It fits Pleurotus ostreatus'needs from mid-April to late-October and it is not fits Pleurotus ostreatus'needs from late-October to early-April.The higher temprature from June to August needs controled by Semi-underground shed.It is 11.84℃between average ten-days temprature diffrence which fits Pleurotus ostreatus'needs.3. The tempratuer in Shed no mycelium bag appeares firstly increases fastly and afterward diclines slowly.Peak appears in 14:00. The peak tempratuer of Bubble top shed with mycelium bag appears in 16:00. The tempratuer in Shed is higher than shed-out. The tempratuer in semi-underground shed changes more gentle than shed-out.4 The respiration rate of mycelium with bag in different fertility period appears slowly-quickly-slowly features.Low temprature can cuts down respiration rate of mycelium with bag and delays mycelium development which it benefits to delays and control fruitbodys growing. The respiration rate of in buds is the mostly high.With the fruitbodys maturing the respiration rate of mycelium with bag becomes slower nd slower. The picked fruitbodys consumes nutrients by breathing. The respiration rate of mycelium with bag is major and it is stronger than the same weight fruitbodys.5 The biological efficiency is lower by picked fuitbodys which diameter is 3～5cm.There about 18.52% biological production can not format goods.It's average water content is 89%.The fuitbodys water contentof Low temprature treated bag is more 2～3 percentage.6. The biological efficiency of Pleurotus ostreatus in Bashang region aeras is between 25% and 35%.The material input ratio is 61.07%.The ratio between output and input is 1.66. The water yielding ratio is 65～76kg/m3and output ratio is 520～612元/m3. The labor ratio of Pleurotus ostreatus in Bashang region aeras is 61.74yuan one day. The land ratio of Pleurotus ostreatus in Bashang region aeras is 15606.9 yuan every 666.7m2.The economic benefits of Pleurotus ostreatus in Bashang region aeras is more than major vegetables.So there is economic advantage than major vegetables in Bashang region aeras to cultivat Pleurotus ostreatus in summer and early-autumn.It provids technology shoosen for agriculture fabric adjustment.
