As compared with the traditional irrigation-traditional fertilization, the following results of the improved traditional irrigation-optimized fertilization were obtained: reduced tiller number per unit area, lower percentage of the tiller ear number/the tiller number, the decreased ear number per unit area, the greatly reduced grain number per ear (1999-2000) and like weight of 1, 000 grains; almost the same plant height; shorter base internode length, a bit more weight per unit internode length, longer internode length under ear; lower LAI values in middle and later stages; coincident process of dry matter accumulation from straight growth onwards, a little more dry matter accumulation amount from earing to maturity; shorter and thicker flag leaf, 2〓 leaf, 3〓 leaf and 4〓 leaf from top, reduced total area of these leave; bigger mean canopy leaf tilt angle, smaller light extinction coefficient , higher ratio of light penetration in the upper, middle and lower parts of the wheat canopy, and tighter plant type; almost identical dynamic change of flag leaf chlorophyll content; and almost the same root amount in 0-120cm soil layer, smaller rate of progressive decrease of the root length density and root weight density with soil getting deep and relatively increased root amount in deeper soil layers.

在传统灌溉-优化施肥条件下，冬小麦单位面积总分蘖数比传统水肥减少，成穗率降低，单位面积穗数有所减少，穗粒数、千粒重无显著性差异；株高基本无变化；基部节间长度缩短，充实度略微增高，穗下节间增长；中后期叶面积指数略低于传统水肥；起身至成熟干物质积累量动态变化过程与传统水肥十分接近，但抽穗至成熟形成的干物质量增加；旗叶、倒2叶倒3叶、倒4叶叶长及总叶面积有所减少，叶片相对增厚；冠层平均叶倾角大，消光系数小，冠层各层的透光率较高，株型紧凑；旗叶叶绿素含量动态变化与传统水肥十分接近；0-120cm土层总根量与传统水肥也差异不大，但根长密度和根重密度随土层深度递减速度较慢，根系在下层土壤的分布相对增多。

In abandoned land and peripheral desert of oasis, influenced by irrigation of oasis, groundwater table has been raised above the critical depth.Because the soil salt cannot be eluviated by irrigation water and precipitation, salt brought to the upper layers of soils by strong evaporation is especially concentrated on soil surface.

绿洲内的撂荒地和靠近绿洲的荒漠草地受绿洲内部灌溉过程的影响，地下水位升高，超过了地下水的临界深度，同时又因为缺少灌溉的反复淋洗，在强烈的蒸发作用下，盐分的表聚现象十分明显，而且整个剖面内盐分的含量都较高，土壤的盐渍化现象非常严重。

And the function of maize yield and irrigation quota in whole growth period in wheat/maize intercropped under the condition of drip irrigation is gained with the regression analysis methods.

运用回归分析得到了间作玉米组分的滴灌条件下产量与全生育期灌溉定额的函数关系。

Show that the 1 lateral 4 rows and 2 laterals 4 rows to increase the volume of nitrogen fertilizer and irrigation will help improve cotton yiled, with 2 laterals 6 rows increased irrigation and fertilizer control in favor of increasing cotton yiled.

综合分析，AFI最能有效降低棉花根区硝态氮损失，使硝态氮和铵态氮含量主要分布在棉花根系有效吸收范围内，有利于棉花氮素吸收和利用。

One reason why AIFU has the best spatial coupling effect is that it has a smaller evaporation area, thus its wate loss by this way is much smaller that traditional full irrigation; leching of fertilizer nutrients is much less than traditional irrigation because fertilizer and irrigating water exists in different furrows, the residual fertility exists in above 60 cm soil profile.

水肥异区交替灌水为一种局部灌水方式，其能够提高水分利用率的原因是可减少蒸发面积，从而减少灌溉水的蒸发损失；对养分的淋溶损失少，使肥料养分主要存在于60cm以上土层。

This article deals with problems of irrigation frequency and crop-water production function of cotton under mulched drip irrigation in agriculture production.

本文针对棉花膜下滴灌生产中急待解决的关于灌水频率和作物水分生产函数问题进行试验研究。

Mulched drip irrigation is a water-saving irrigation in Xinjiang, one of the more successful technologies, which water-saving effect is good, yield increase significantly, the technology is widely used in Xinjiang and development.

膜下滴灌是新疆节水灌溉比较成功的技术之一，它节水效果好，增产效果明显，这项技术在新疆得到了广泛应用和发展。

Therefore, the soil moisture monitoring program of mulched drip irrigation of cotton fields can be designed by the spatial distribution of soil moisture before 1st irrigation.

因此，根据第1次灌水前田间土壤水分空间分布情况，设计的监测点布设方案可以满足其后各次灌水的墒情监测要求。
