从药物的利用与研究，杀虫剂和除草剂的研究，肥料和饲料的利用与研究三个面综述目前国内外对肿柄菊的开发利用与研究现状。

In conclusion, altering conventional fertilizer kinds can improve the quality of green Chinese onion.

因此，在相同肥料用量的情况下，施用螯合肥处理要明显优于常规施肥，通过改变传统用肥种类可以提高大葱的品质。

Some effective mulching materials are: pine bark, coarse textured peat, ground corncobs, pine straw, and well-rotted strawy manure.

一些有效的覆盖材料是：松树树皮，纹理粗泥炭，碎玉米芯，稻草松树和良好的腐烂strawy肥料。

Results showed that the topsoil structure of the CK treatment was dense with little porosity developed, and the soil microstructure was sandy granular fabric - granular fabric. In these treatments using chemical fertilizers only, the soil particles did not form soil structure with little porosity, and the soil microstructures in the N, NP or NPK treatment were observed as prophyropectic fabric-fine sand agglomerplasmic fabric, much better than the CK treatment. In those treatments receiving farm manure alone or farm manure plus chemical fertilizers, the quantity of groundmass increased obviously. The soil had a loosen structure, higher porosity, enriched animal and plant residua, iron-manganese nodules and humus, and more micro-aggregates developed. The soil microstructure of the MNPK treatment was pectized-compacted takyric fabric-intertextic fabric, the best microstructure observed among all the treatments.

结果表明：长期不施肥料的CK处理，土壤耕层结构致密，很少有孔隙发育，土壤微结构为结构较差的碎屑聚积状-沙粒聚积状；长期单施化学肥料，土壤颗粒未形成结构体，少孔隙，土壤微结构主要为斑晶胶凝状－细沙粒聚积状结构，土壤结构比CK处理优；长期施用有机肥或有机无机肥料配施的处理，土壤粗颗粒数量显著增加，结构疏松，孔隙量大，动、植物残体丰富，有铁锰结核和腐殖质的形成和微团聚体的发育，土壤微结构类型以MNPK处理最好，为胶凝紧实状－多孔状结构。

The guano of bat s has long been used for agricultural fertilizer.

The guano of bats has long been used for agricultural fertilizer .

蝙蝠的粪便在农业上长久以来就用作肥料。

In the 1800s the birds' guano—a necessary part of their nesting environment—was stripped away from their nesting grounds to provide fertilizer for farms.

在1800年代鸟类海鸟粪一个必要组成部分，他们产卵环境被剥夺了，从他们的栖息地，提供肥料的农场。

Also what was and continues to be very useful is the guano of the pigeons, the droppings, which is an excellent fertiliser for the fields of the residents.

在19世纪期间，雏鸟小鸽子开阔了运输出口的商机，从以前甚至到现在，仍旧非常有用的就是鸽子的粪便，对当地农田来说，是非常棒的肥料，在威尼斯时代，鸽子也被用来做传信鸽。
