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。

Both the new peniculus 1 and the old haplokinety separated at the telophase.The two germinal rows germinal rowsfor both the daughter cells appeared almost at the same time;(2) The macronucleus became shorter and thicker, finally oblate during the division of the cell. Then the macronucleus restored its original shape, band-like form. The micronucleus were divided into two before the macronucleus division;(3) The original scopula and stalk contributed to the old cell. The new cell formed scopula gradually after the cell division.

同时,新仔虫的第一咽膜(P′1)也开始由老单毛基索复制,并在细胞分裂后期与老结构分离;(2)大核在虫体分裂过程中由长带状逐渐缩短变粗至扁圆形,于虫体即将分开时迅速拉长,然后分裂为二个新大核;小核分裂先于大核,在两仔虫口纤毛器即将分开时完成;(3)原帚胚及柄归属老仔虫,新仔虫的帚胚在虫体分裂后逐渐形成,柄内肌丝则在柄鞘形成后逐渐长出。

In this paper, cholinergic neurons was mapped in the two kinds of birds (Emberiza rutila and Fringilla montifringilla) by using immunohistochemical method.The soma size and cell density of cholinergic neurons in the three song control nuclei, the higher vocal center, the robust nucleus of the archistriatum and area X, were measured and compared. Here we discussed the distribution of cholinergic neurons and their effect on the process of song producing and song learning.
