摘要通过对降水量、地面径流量、作物需水量的综合分析,结合山西省中长期天气趋势预报,在客观定量地评价年度内农田水分盈亏指标的基础上,实施集成旱作技术,对玉米和谷子进行全生育期农田管理,取得明显效果。 - Drip irrigation under mul : h is a new irrigation method , as utiliz e the advance of drip irrigation and plastic film cultivation technique . the conditions influenced crop water requirement are changed in drip irrigation under mulch , thus crop water requirement pattern is different from conventional irrigation forms . it is very useful to research field mulched crops water requirement pattern watering with drip irrigation
膜下滴灌是地膜栽培与普通地表滴灌相结合的产物,在地膜覆盖和滴灌的综合效应下,作物的生长与在常规条件下不同,因此影响作物需水量的一些基本条件都发生了变化,对于膜下滴灌作物需水量和作物系数还需要做进一步研究。 - Acceding to the theory of crop water requirement , maximum potential evapotranspirations are calculated by applying fao penman - monteith method , and then we obtain the water requirement , water balance and water correction factors ect . of main crops ( spring maize , summer maize , spring wheat , winter wheat , cotton ) and different type grasslands , and the space - time distribution regularities of water requirement of cropland and natural grassland are analysed , the result show : the water requirements of same kind crop in different areas are different , water satified degrees are different to different crops in the same area , and water requirement of same crop are different between years for climatic variation ; the water requirements of main crops are increasing from east to west and from south to north , water satified degrees are decreasing from east to west and from south to north . in growing season , there are deficits in crops water supply in most area , so the irrigation is needed to meet the requirement for crop growing normally
根据作物需水的理论和方法,采用计算精度较高的faopenman - monteith方法( 1998 )计算了半干旱区最大可能蒸散,并基于此计算五种主要旱地作物(春玉米、夏玉米、春小麦、冬小麦、棉花)和不同类型的天然草地的需水量、水分盈亏、水分订正系数等,分析了农田和天然草地水分供需的时空分布规律,结果表明:不同地区同一种作物的需水量是不同的,同一地区对不同作物的水分满足程度是不同的,而且同一种作物在同一地区随着气候的变化需水量也会有一个年际变化;主要作物需水量由东向西,由南向北递增,正常生长发育的水分保证程度由东向西,由南向北递减。 - The first part is about the computing of crop water requirements ( or crop evapotranspiration ) and net irrigation requirements ( nir ) of ten crops in bojili irrigated district . then the traditional irrigation schedules of winter wheat and summer maize , which are the main crops in bojili , were evaluated with simulating model isareg . third , the field application efficiency in the experimental areas was evaluated from three methods
本文即是由灌区实测资料计算各种作物需水量,推求其净灌溉需水量;然后通过模型检验现行作物灌溉制度是否具有合理性,并对田间灌溉系统进行评价,求其实际田间灌溉效率;最后由两种不同灌溉制度方案的对比,确定试区合理的作物灌溉制度,在此基础上求出各代表年的田间灌溉需水量和用水过程线。 - At present , the studies about the controlled alternate furrow irrigation are focused on how it affects the water physiological indexes , water consumption and yields of crops . but , some problems suc h as the soil infiltrative parameters , irrigating water advancing , water redistribution in soil , calculation of crop water requirement and water consumption , and the upper and lower limit indexes of soil moisture , guiding a field irrigation after the controlled alternative furrow irrigation is implemented in field , have not been researched systematically and deeply . if these problems could not been solved commendably , the popularization of controlled alternate furrow irrigation will be affected
然而,目前有关交替隔沟灌溉的研究还主要集中于这种灌水方式对作物水分生理指标、耗水量和产量的影响方面,而对大田采用这种灌水式后的土壤入渗参数变化情况、作物需水量与耗水量计算、以及指导大田灌溉的水分下限控制指标等与大田生产实际密切相关的几个问题基本上还没有进行系统的深入研究,而这些问题如不能得到很好地解决,势必会对这种灌水方式的推广应用产生严重的影响。 - The function of the software is useful , it has provided many functions such as the calculate of crop water requirement , pipeline layout ( automatic layout and manual operation ) and its optimization , pipe diameter optimization . investment budgetary estimate and economic beneficial result can be result . and can rapid create plan and do plan comparison , the software provides many kinds of result output such as graph . text , table and so on
该系统可以实行作物需水量计算,系统设计流量推算、管道水力计算、工程投资概算,经济效益分析等功能,建立了常用的数据库(管材、管件、水泵和电机等)并对其进行管理和维护,可以实现包括管道布置、管径优化、管材选择等多种参数选择在内的多种方案比较、优选。系统能提供图形、文本、表格等多种形式的成果输出,人机交互界面友好,操作方便。
