【摘要】 在对石河子地区14科31属34种作物VA菌根分布调查基础上,对其感染率及部分生态环境进行了一些测定,同时对VA菌根茵的基本形态结构作了观察.石河子地区气候较干燥,调查田块土壤 PH值均偏碱性,作物仍能形成丰富的 VA菌根,说明VA菌根的生态适应性很强,能够广泛分布于自然界.更多还原

【Abstract】 On the basis of investigating Vesicalar - Arbuscularny - corrhiza (VA) of 34 different crop species within 31 genus of 14 families, the infest rate and ecoenvironment and the forms and structures of VA were studied.The climate is fairly dry, the soil PK of the fields investigated tended to alkyls,Under such conditions the VA could still be formed on crop roots. It indicates that the VA can be adopted to different e-cological conditions can distribute widely in nature.更多还原
