clover的示例

• Progress in breeding perennial clovers for temperate agriculture.

• Influence of undersown clovers on weeds and on the yield of winter-wheat in organic farming.

• We lose the clovers, and in addition to lime we have to use phosphates extensively in order to retain the clovers.

• In order to restore fertility, an increased acreage of rotation grasses and clovers, or leys, and an increased head of livestock, must not only be contemplated but secured.

• Fodder crops such as modified legumes—clovers, lucerne or ryegrass—may have inserted genes which not only increase feed utilisation but also prevent serious metabolic disorders in the animals that eat them.

• Evaluation of berseem clover in diets of ruminants consuming corn crop residues.

• A no-tillage tomato production system using hairy vetch and subterranean clover mulches.

• Influence of structure and composition of ryegrass and prairie grass-white clover swards on the grazed horizon and diet harvested by sheep.

• Seeds of small-seeded clovers passed through sheep in greater numbers (58+ 72%) than did seeds of larger-seeded species (10+40%).

• They clearly demonstrate the role of small-seeded legumes (51 mg) in grassland improvement, especially the small-seeded clovers.

• Horses, which digest dry clovers and straw in dung, cannot digest grains of barley.

• In contrast, the populations of relatively larger-seeded clovers became harder (germination reduced) after ingestion.

• Since then, the nitrogen fixing properties of clovers together with their high protein and mineral content have become more highly valued and reliability has been further improved through breeding.

• Between the blocks there is a piece of ground planted with a mixture of different herbs, clovers and grasses, which acts as a bank for beetles.

• Higher microbial biomass carbon in gypsum treatments corresponded with lower exchangeable sodium percentage, higher availability of nitrogen and potassium and greater total yield of sensitive winter clovers.
