Novel method for preparing solid frngus pesticide by deep layer fermentation

The present invention adopts liquid fermentation to produce hyphae, and utilizes solid deep layer fermentation to culture lots of conidia, the thickness of the fungi cultured by adopting said solid deep layer fermentation method can be up to 30-100 cm, and the area is 2-8 sq.m. According to the physiological characteristics of entomomycete products of muscardine and green muscardine, etc. the different temperatures and humidities can be selected for meeting the requirements for hyphal growth and spore development. Its safe fermentation temperature is at 20-30 deg.C, and its humidity can be regulated so as to promote sporogenesis and drying. 本发明涉及一种真菌杀虫剂固体深层发酵制造的一种新方法，属于生物发酵工程技术领域。本发明采用液体发酵生产菌丝、固体深层发酵培养大量分生孢子。这种固体深层发酵的方法培养真菌的厚度可达30-100cm，面积为2-8平方米，比浅盘培养方法的工效提高数十倍。本发明采用固体深层发酵，可根据白僵菌、绿僵菌等虫霉产品的生理特点，选用不同的温湿度来满足菌丝生长和孢子的发育。可对气温、品温及送风温度进行自动控制。安全发酵温度在20-30℃，并可调节干湿度，促进产孢和干燥。可使虫霉产品的工业化生产成为现实。
