The result indicated that, This variety resistance is strong, The sowing time meets arid long clearly does not have the rain the weather, The soil field capacity is 43.5%(normal soil field capacity 60%), the rain water is insufficient, Rate of seedlings emergence above 85%, Basically achieves seedling is much longer and stronger; Jointing later period trumpet-shaped object stage, Meets the continuous and incessant rains little clear climate, Suffers the water logging disaster, Soil field capacity reaches above 85%, Partial is low-lying place is flooded, But the corn growth is normal, Ye Sachem is green, The root system is developed, Has not discovered the rotten root phenomenon; Is pulling out, the spinning, the pollination stage male, Bitter experience hot summer crop damage and storm disaster, The corn normally pulls out the male spinning pollination to busload.

结果表明：该品种抗逆性较强，播种期遇干旱久晴无雨的天气，土壤田间持水量为43.5%（正常土壤田间持水量60%）、雨水不足，出苗率在85%以上，基本达到苗齐、苗壮；拔节后期喇叭口阶段，遇到久雨少晴气候，遭受水涝灾害，土壤田间持水量达85%以上，部分低洼处被水淹，而玉米生长正常，叶色深绿，根系发达，未发现烂根现象；在抽雄、吐丝、授粉阶段，遭遇伏旱及暴风雨灾害，玉米正常抽雄吐丝授粉结实，产量未造成较大影响，基本上达到常年稳产，每公项达到8400kg以上。

In this paper, as a case of Karamay, we have studied on space-time changement of soil quality in oasis of arid area. We measured quality for different land use types and years in same type by combinativing field sampling for Karamay in Xinjiang and analysis in laboratory, which is directed by former theory of soil quality. Then we did integrated evaluation of soil quality for different land use types, and had drew some conclusions as followed: In four land use types, the soil bulk density of layers(0～15cm) for farmland and tree land is bigger than the other land use types.The organic matter of every layer in manpower Tamarix Bulrush land is bigger; organic matter of Tamarix Bulrush land release efficiency nitrogen which result ration of C/N is higher; total nitrogen of all layers in farmland variety great as being effected by mass use of nitrogen in agriculture; deadwood and defoliation of tree、shrub and bulrush pooled in 5cm layer to result that quick nitrogen is the biggest among all layers. The total salt of nature shrub tree land for every layer being bigger than farmland explain that nature shrub thee land strongly stand salt and farmland for basification in this area; that the nutrient of face layer is bigger than the ground layer may be explained by that vegetation gather nutrient to be stored in deadwood and defoliation.

本文对以克拉玛依为例，对干旱区绿洲土壤质量的时间空间变化进行研究，在有关土壤质量的研究理论指导下，通过田间调查取样和室内分析相结合的方法，对新疆克拉玛依市农业开发区的不同土地利用方式及同一土地利用方式下不同利用年限土样土壤理化性质进行测定，从而对新垦绿洲不同土地利用类型土壤质量进行综合评价，结果如下：四种土地利用方式中，农地、乔木林地表层(0-15cm)土壤容重较大；各土层人工柽柳芦苇地的土壤有机质含量均较大；柽柳芦苇地的有机质在矿化过程中所释放出有效氮，导致柽柳芦苇地的C/N比例较高；受到农业耕作使用大量氮肥的影响，农地各土层全氮含量变异较明显；乔木、灌木及芦苇的枯枝落叶主要集中在5cm范围之内，导致几种土地利用方式类型下该层土壤速效氮最大；天然灌木林地的土壤总盐在各层均较大，其次是农地，说明天然灌木林地的高耐盐能力，以及该区农业生产用地的土壤盐碱化程度较重。
