在黑木耳、香菇生产中往往由于水分条件差、菌体长期达不到菌丝和子实体生长适宜的含水量,以致不能正常发育,严量低。如1986年严重干旱,安康地区投产木耳43万架,平均单架产量仅1.1公斤;投产香菇18万架,单架产量不足0.5公斤。按目前生产水平,木耳、香菇年单架产量分别以2.5公斤、1公斤计,那末就有一半的棒木资源被白白的浪费了。因此,木耳、香菇生产要认真解决灌溉问题。微喷是近年新发展的一项微量灌溉技术,技术简单、耗能低,喷头只有指头大小,工作压力小,喷出的水似“毛毛雨”,对作物的冲击力小,很适宜于木耳、香菇灌溉。试验证明,它可使棒体吸水率高,增加菌场湿度,降温等特点,因此,增产显著,投资回收快,具体表现在:
In black fungus, mushroom production is often due to poor water conditions, bacteria long reach mycelium and fruiting body growth suitable moisture content, so that can not be normal development, low stringency. Such as the severe drought in 1986, putty production in Ankang 430,000, the average single-crop output of only 1.1 kg; put into operation 180,000 mushrooms, single-frame production of less than 0.5 kg. According to the current production level, fungus, mushrooms, single-crop production were 2.5 kg, 1 kg, then there are half of the great wood resources were wasted. Therefore, fungus, mushroom production to seriously solve the irrigation problem. Micro-spray is a newly developed micro-irrigation technology in recent years. It has the advantages of simple technology, low energy consumption, small nozzle size and small working pressure. The sprayed water is like “drizzle” and has little impact on crops. It is suitable for fungus, Mushrooms irrigation. Experiments show that it can make the rod water absorption, increase the bacteria field humidity, cooling and other characteristics, therefore, a significant increase in output, investment recovery faster, specifically in:
