香菇菌筒浸水补肥技术

作者 李光河 《河南科技(乡村版)》 2004年第2期16-16,共1页
香菇长在菌筒上,菌简一靠养分,二靠水分。养分只能逐步分解,水分一经长菇却很快消耗。因此,经过几批长菇后,当菌筒重量明显下降时,子实体形成受到抑制,如不及时浸筒补水,产量就会受到影响:为使菌丝尽快恢复营养生长,加速分解... 香菇长在菌筒上,菌简一靠养分,二靠水分。养分只能逐步分解,水分一经长菇却很快消耗。因此,经过几批长菇后,当菌筒重量明显下降时,子实体形成受到抑制,如不及时浸筒补水,产量就会受到影响:为使菌丝尽快恢复营养生长,加速分解和积累养分,奠定继续长菇的基础,就必须及时浸水补肥。每浸一次水。 展开更多

Seawater intrusion problem is considered in this paper.Its mathematical model is anonlinear coupled system of partial differential equations with initial boundary problem.It consistsof the water head equation and the salt concentration equation.A combined method is developedto approximate the water head equation by mixed finite element method and concentration equationby discontinuous Galerkin method.The scheme is continuous in time and optimal order estimates inH^1-norm and L^2-norm are derived for the errors. 展开更多
