释义 | legume noun[ C ] biology specializeduk /ˈleɡ.juːm/ us /ˈleɡ.juːm/ a plant that has its seeds in a pod, such as the bean or pea荚豆 Types of plant acanthus air plant amaranth Andromeda angiosperm early emergent evergreen fiddlehead grower mossy mugwort mustard non-hardy non-legume spleenwort starter plug succulent sundew tenderness Related wordleguminous Examples of legumelegume Key examples are systems combining no-till seeding, crop-rotations including legumes, plus maintenance of continuous crop-residue cover to the soil. But this did not change the relative profitability of the treatments: sole maize fertilized and unfertilized remained more profitable than the respective legume intercrops. Very large increases (well over 100 %) in the price of legumes would be required to make legume-maize intercrops more profitable than sole maize. For mixed grass+legume silages, the case was more complex, since the value of the silage is not independent of its composition. Output taxes consisted of the tithes (osur) applying primarily to grains, legumes, and fibers. The intercropped legumes grew moderately well most years. Plant husbandry and management techniques for growing grain legumes under simulated tropical conditions in controlled environments. Absent from private sector research, not surprisingly, are many crops cultivated by the world's poor, including small-grain cereals, tubers and legumes. This paper reports the results of on-farm testing of grass+legume pastures assessed in terms of milk production in dual-purpose systems. However, other experiments have indicated the beneficial effects of perennial legumes and no-till agriculture on soil nitrogen. The present study pointed to the critical role of legumes, especially perennial alfalfa, for increasing the energy efficiency of a cropping system. It is concluded that grass+legume mixtures increased milk yields on farms. Legume-based cropping systems have reduced carbon and nitrogen losses. With the exception of phosphorus, treatment effects on legume growth were marginal. Each farmer experimenter rated the performance of the legume fallows against the control with indicators which they developed in the second year of experimentation. These examples are from corpora and from sources on the web.
