疏松土壤

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。

Carposina, Navicula caterpillars, flat postornata, soil pests such as mole cricket, can they turn to land the ground froze to death;also bollworm damage, stick insects, sawfly wheat, locust pupae Room nests, etc., to prevent its emergence or incubation in order to better carry out Overwintering insects buried in the 10 ~ 15 cm layer, it should be frozen in the soil before or early spring, while the pests,"sleep" when the Land20 ~ 30 cm, so that exposure of adults or pupae on the ground was frozen to death or birds pecking; such loose soil can also help the soil ripening, and enhance the permeability of soil.

害虫越冬入土在10～15厘米层间，故应在土壤封冻之前或早春，趁害虫"熟睡"之际，将田土深翻20～30厘米，使成虫或蛹暴露在地面上被冻死或被禽鸟啄食；这样也可使土壤疏松，有利于土壤的熟化，增强土壤通透性。

深松是在翻耕基础上总结出来的利用深松铲疏松土壤、加深耕层而不翻转土壤、适合于旱地的耕作方法。

Results are as following:The causes of grassland desertification of Hulunbeir are the outcome of interaction of nature and the human beings. Among these reasons, the loose soil texture, which was formed in the fluviolacustrine sediment during Quaternary, establish the physical ground, and the drought and wind is the natural force of grassland desertification. And then over-cutting forest, over-grazing grassland, imbalance of resource utilization and estrepement reduce the coverage of vegetation, therefore provide necessary conditions for the grassland desertification.

其中，形成于第四纪河湖相沉积沙的疏松土壤母质，为日后土壤风蚀奠定了深厚的物质基础；干旱多风的气候条件构成了草地风蚀沙化的自然营运力；而人为过度砍伐沙地林木资源、沙质草地长期超载放牧、资源利用不平衡以及乱垦、滥挖等不合理经济行为，又降低了沙化草地植被覆盖度，为草地风蚀沙化提供了必要条件。

The purpose of researching the fields of stubble is that corn stalks will be aimed at post-harvest stubble part, above ground and below-ground stubble of the main stem and crush evenly Hunban in the topsoil, To loose soil and increase soil organic matter, improve the physical properties of the soil, increase the aggregate structure function.

本课题研究的灭茬还田机，目的在于将玉米秸秆收获后的根茬部分、地面以上留茬及地面以下主茎部分粉碎并均匀地混拌在耕层中，达到疏松土壤、增加土壤有机质、改善土壤物理性质、增加团粒结构的功用。

The results indicate that:(1)Compare with the comparion, the soil physics character are improved after vegetation restortion , the soil unit weight in cyclobalanopsis glauca, Pinus elliottii, Robinia pseudoacacia , mixed forest and fire slash shrub separatly are 1.525g/cm~3, 1.426 g/cm~3, 1.625 g/cm~3, 1.482 g/cm~3, 1.423 g/cm~3. We can find the soil unit weight in other forest all bigger than the comparion (1.580 g/cm~3) except Robinia pseudoacacia .All these mean forest soil is looser and better capacity for aerated and dank.

结果表明：(1)植被恢复后林地土壤物理性质有良好的改进，青冈、湿地松、刺槐、混交林、火烧迹地灌丛容重分别为：1.525g/cm~3、1.426g/cm~3、1.625g/cm~3、1.482g/cm~3、1.423g/cm~3，除刺槐外其他林地均低于对照(1.580g/cm~3)，上述几种林分的孔隙度分别为：45.872%、51.956%、44.093%、50.485%、55.648%、47.228%，说明林地内土壤较对照更为疏松、通气透水能力更强，更有利于土壤微生物的活动，为研究区土壤肥力的提高奠定了基础。
