ABSTRACT

A completely randomized factorial experiment was conducted to evaluate the growth and biomass production of single- and mixed crop species inoculated with mycorrhizae. Radish, (R), safflower (SF), pearl-millet (PM), mustard (M), field peas ((FP), faba-bean (FB), common vetch (CV), and berseem clover (BC) and their blends as R-SF-PM-M, FP-FB-CV-BC, R-SF-PM-M-FP-FB-CV-BC, R-SF-M-FP-FB-CV-BC, and PM-FP-FB-CV-BC were planted in a pot culture. The mycorrhizal inoculum significantly influenced the cover crops growth and biomass production under sterilized soils than that of non-sterile soils. While the safflower produced the highest total biomass, the pearl millet and field peas produced the lowest total biomass. Generally, in sterile and mycorrhizal conditions plant grown better and have high total C fixation. Within non-sterile and mycorrhizal inoculation, Safflower (1383.1 g C m⁻²) and Berseem Clover (1235.5 g C m⁻²) as a single species have fixed highest amount of carbon as biomass. Mycorrhizae inoculated BC+CV+FB+FP+SF+PM blends had a return of 1365.0 g C m⁻² in non-sterile soil. Our results suggested that cover crops in single or mixed stands with mycorrhizal inoculations are expected to provide a significantly greater amount of biomass, which would contribute to soil organic matter and nutrient recycling for crop production.

摘要

进行了完全随机的析因试验，以评估接种了菌根的单种和混合作物的生长和生物量生产。萝卜（R），红花（SF），珍珠粟（PM），芥末（M），豌豆（（FP），蚕豆（FB），普通v子（CV）和伯来三叶草（BC）和它们的混合物为R-SF-PM-M，FP-FB-CV-BC，R-SF-PM-M-FP-FB-CV-BC，R-SF-M-FP-FB-CV-BC和PM-FP-FB-CV-BC种植在盆栽中，在无菌土壤中，菌根接种物对覆盖作物的生长和生物量产生显着影响，而在非无菌土壤中，红花的总生物量最高。小米和大豌豆的总生物量最低，通常，在无菌和菌根条件下，植物生长更好，总固碳量高。^-2）和Berseem Clover（1235.5 g C m ^-2）作为单一物种具有固定的最高碳量作为生物量。在非无菌土壤中，菌根接种的BC + CV + FB + FP + SF + PM共混物的回报为1365.0 g C m ^-2。我们的结果表明，采用菌根接种的单一或混合林分覆盖的农作物有望提供大量的生物量，这将有助于土壤有机质和作物生产中的养分循环利用。
