2摘要：本研究是在2006-2007年连续两个季节在Kafr Dawood，Menoufiya，埃及的一个私人农场进行的。研究了2种生物肥料（AM-菌根真菌、共生固氮菌（Rhizobium sp.）和固氮菌（Azotobacter sp.）除了B之外。在土壤中添加天然替代肥料，如磷酸盐和长石，以及它们对生长参数，生理和微生物学参数的影响。另外，菜豆（Phaseolus vulgaris，L.）鲜产量及其组成部分。结果表明，处理9（AM真菌、共生固氮菌和非共生固氮菌、环状芽孢杆菌+磷矿粉+长石的混合物）在株高、分枝数、单株结瘤数和鲜重产量（吨/料）等方面均上级对照和未接种的2株。接种也产生了最高值的固氮剂和B。在以磷矿粉和长石为基质的土壤中，菜豆根际的circulans种群对AM真菌的侵染率最高。各因子间的交互作用对大部分性状的影响均达到显著水平。因此，我们的研究支持使用生物肥料和天然替代品作为可持续农业的有益廉价肥料来源的新趋势。
2 Abstract: This study was conducted in two successive seasons of 2006-2007 in a private farm at Kafr Dawood, Menoufiya, Egypt. It aimed to investigate the effect of inoculation of snap bean plants with 2 2 biofertilizers (AM- mycorrhizal fungi, symbiotic N -fixers (Rhizobium sp.) and asymbiotic N -fixers (Azospirillum sp. and Azotobacter sp.) in addition to B. circulans on soil amended with natural alternatives of fertilizers like rock phosphate and feldspar and their effect on growth parameters, physiological and microbiolgical parameters. In addition, snap bean (Phaseolus vulgaris, L.) fresh yield and its components. The obtained results indicated that the treatment No. 9 (mixture of AM- fungi, symbiotic and asymbiotic 2 N -fixers and Bacillus circulans + rock phosphate + feldspar) was superior in plant height, number of branches, number of nodules per plant and fresh yield (ton/fed) when compared with control and the 2 uninoculated plants. Inoculation with produced also the highest values of N -fixers and B. circulans populations in the rhizosphere of snap bean plants cultivated in soil amended with rock phosphate and feldspar and produced the highest infection percentage of AM- fungi. The interaction among the studied factors had significant effects on most studied characters. So, our study supports the new trend of using biofertilizers and natural alternatives as beneficial cheap sources of fertilization for sustainable agriculture.
