<p>温故而知新嘛！呵呵</p>

<p>作物栽培学里课程学过。<br/>毕业后未从事农业相关的工作，现在忘得差不多了。<br/>学而时习之，不亦悦乎。<br/>在工厂打工多年，开了个小菇场利用业余时间和助手一起实践一下理论所学。<br/>也经常游离于论坛之上，吸取些名师教诲。<br/>每每有所收获都十分高兴，心存感激，但又不知如何回报老师们。<br/>所以胡乱跟贴，希望把自己的体会共享。希望不枉老师辛苦加砖。<br/>万变不离其宗，食用菌菌丝和子实体的营养运输过程与植物应该类似。<br/>所以理解好植物的养份传递细节，对于我们把握栽培过程中某些栽培措施的所以然有所帮助。<br/>谢谢陈老师加砖。</p>

楼上说得好极了，我是新手，虽然什么都不懂，可我相信老师们既然出贴，那么这些看似和食用菌不相关的知识就不是那么简单。好好学
