Based on chemical analysis, the water in the offtakes was entirely salty or heavily salty, mainly resulting from fall irrigation.

同时，排水渠中高含盐量是随着灌区的秋浇活动而持续发生的，并且与灌溉引水量成比例关系。

By the chemical evaluation, the water in offtakes was entirely salty or heavily salty, which was mainly resulted from fall irrigation.

Conventional tillage with bare ground, conventional tillage with straw incorporated and no-tillage with straw mulch were studied in the Hexi corridor of Gansu provience. The result showed: on summer fallow NTS stored soil water more than CTB and CTS by 30.62mm and 23.91mm, respectively; the winter storage irrigation quotas should be reduced to 900~1350 m^3/hm^2 on winter fallow; evaporation controlling rate arrived 38.1% and 7.3% at winter storage irrigation quotas 975m^3/hm^2 and 2100m^3/hm^2, respectively; NTS did not reduce ET during the spring wheat growth stage; yields different between treatments was not significant.

对甘肃河西内陆河灌区采用常规耕作、秸秆还田和覆盖免耕技术的农田水分效应进行研究，试验结果表明：在夏季休闲期，覆盖免耕比常规耕作和秸秆还田多贮水30.62mm和23.91mm；冬季休闲期可将大定额的储水灌溉减少到975~1350立方公尺/hm^2；覆盖免耕抑制蒸发率在储水定额为975立方公尺/hm^2时达到最大值38.1%，而在2100立方公尺/hm^2时最小为7.3%；覆盖免耕在作物生育期并没有减少土坡耗水量；各处理产量之间没有显著差异。

The groundwater in well-irrigated area, Guangrao county is very important to the agriculture production and their people living.

The paper treatments the time series by the artificial nerve network technology, defines the network structure by the self - correlation analysis, sets up the artificial nerve network model of well irrigation paddy water demand for uncertainty relation between inside and outside factors of water demand series.

应用人工神经网络技术处理需水量时间序列，通过自相关分析，确定网络结构，建立了井灌水稻需水量的人工神经网络模型，解决了需水量序列内部及其外部诸多影响因素之间的不确定关系，预测精度较高，可在灌区决策管理中应用。

This paper discusses the method to eliminate error during the course of small_ scale of landscape drawing of irrigation area.
