本文筛选出蒙古口蘑不同菌液对苦菜、生菜有明显的增产作用。B菌液施入温室土壤内，苦参与对照相比鲜重增产48．40％，干重增加83．62％。生菜与对照相比鲜重增产23．3％，而对生菜干重无影响，表明蒙古口磨B、C、A处理促进生菜对水分的吸收。  相似文献   

Modelling the morphogenesis of annual sowthistle, a common weed in crops     

S-Zahra-Hosseini Cici  Steve Adkins  Jim Hanan 《Computers and Electronics in Agriculture》2009,69(1):40-45

This paper presents an architectural model of sowthistle which is an important weed in most crops. The sowthistle model was developed using the Lindenmayer systems formalism and parameterised according to measurements of structure of several sowthistle plants. The growth relationships of the sowthistle architecture were captured by the model and simulated graphically. The model reproduced the architectural development of individual plant organs faithfully when verified for leaf number, plant height and leaf area at different temperatures. Future improvement of the model and its practical aspects are described.  相似文献
