地木耳对蕃茄生长的影响

地木耳是蓝藻门植物，具有生物固氮作用，分别以地表施加、土中施加、浸泡材料与酶提取液的方式在番茄的营养生长期和花蕾期施加，均有增肥效应。地表施加效果最好，且营养生长期施加的作用大于花蕾期；地木耳的用量随每一植株生活的环境不同而异。只要使地木耳保持活力，白天进行光合作用，夜间便可进行固氮作用，它可以持续地进行生物固氮，且具有累加效应。

THE EFFECT OF NOCTOC COMUNE ON BLOOM AND NUTRITVE GROWTH OF PLANT

Nostoc commune is a kind of plant in Cyanophyta which has the function of biologicla nitrogenfixation. Observatious indicate that it can improve fertility level when added to tomato during thestage of nutritive growth and early florescence,It can be added on the soil surface,in the soil,or inform of dunked meterial and extraction of liquid.The best result occurs when Nostor commune isadded on the soil surface,and when it is added during the stage of nutritive growth,the effect isgreater than during the stage of early florescence,The amount of Nostoc commune used changeswith specific habitat of each plant.Only if its activity can be kept and let it photosynthesize in day-light,it can fix netrogen at night and the biological nitrogen fixation is continuous and has accumu-lative effect.
