In the rainfed farming area on the Loess plateau, water required to produce winter wheat is regulated by mainly relying on soil moisture stored. This test under artificial control is used to determine the productive capacity of water stored by "soil reservoir" and the field water consumption and its consumption coefficient of winter wheat.Generally,from 19% to 24% varies water holding capacity in Loutu soil in Guan zhong.The amount of soil moisture must be about 200mm before sowing, the certain amount of output...

In the rainfed farming area on the Loess plateau, water required to produce winter wheat is regulated by mainly relying on soil moisture stored. This test under artificial control is used to determine the productive capacity of water stored by "soil reservoir" and the field water consumption and its consumption coefficient of winter wheat.Generally,from 19% to 24% varies water holding capacity in Loutu soil in Guan zhong.The amount of soil moisture must be about 200mm before sowing, the certain amount of output can be gained in case of drought and little rainfall in winter and spring. In case of soil fertility not becoming the constraint, water consumption coefficient of winter wheat must be 0.75mm/ kg·mu. Under the condition of moisture stored in soil reaching 400 to 600mm, wheat yield of 200-300kg/mu can be obtained.Thus, wheat yield can be improved with an inerease of storage of soil moisture, and also shows a positive correlation with water consumption to some extent.

黄土高原旱农区,冬小麦生产所需水分主要靠土壤贮水进行调节。试验在人工控制条件下,测定了“土壤水库”贮水的生产能力,冬小麦的田间耗水量与耗水系数。关中(土娄)土的田间持水量一般变动在19%至24%之间。在冬春干旱无雨水保证的条件下,播前土壤贮水约在200毫米以上才可获得一定产量。在肥力不成为限制因素的条件下,冬小麦最低的耗水系数为0.75毫米/亩·公斤,在土壤贮水400-600毫米条件下,冬小麦可获得200-300公斤/亩的产量。冬小麦的产量随土壤贮水的增加而提高,与耗水量呈一定程度的正相关。

According to the analysis of the precipitation-soil-crop system in Huang-Huai-Hai plain, this paper suggests that due to the midsummer rainfall plays an very important role in supplying water to crops, so in this plain dryland farming have greater potentialities.In case of irrigation area which can not be largely improved recently, we should develop at the same time the dryland farming and irrigated farming in this area, and possibly use the natural resources (Climate, underground water and so on) to develop...

According to the analysis of the precipitation-soil-crop system in Huang-Huai-Hai plain, this paper suggests that due to the midsummer rainfall plays an very important role in supplying water to crops, so in this plain dryland farming have greater potentialities.In case of irrigation area which can not be largely improved recently, we should develop at the same time the dryland farming and irrigated farming in this area, and possibly use the natural resources (Climate, underground water and so on) to develop the dryland farming. In other case, we should also study the rule of water consumptioni n irrigation areaed for limit irrigation water. Some technique can be used for raising the efficiency of water utilization, such as the use of chemical fertilizer, antt-infil-tration irrigation system etc.

小麦全生育期产量随蒸散量而增加,>500mm后产量下降,经研究与实践证明,一般年份该地区水浇地小麦产量比旱地增产,黄河以北尤为突出,但旱作农业基于土壤可贮存的 1/3的雨季降水,而有一定潜力。因此,用系统的观点一方面充分利用该地区的自然降水,发挥土壤水库的贮水作用以发展旱作农业;另一方面充分利用现有水浇地节水灌溉,并通过各种有效措施,提高水分利用率。

The field experinents and observations were made to study soil moisture behaviorsand its productive efficiency in farmlands showed that when rainfall was below 212.7mmin the water storage period of summer fallow (July to August )in this region, there ex-isted a dry soil layer in the depth of 1--1.2 meters, which has an important impact uponthe utilization of soil moistuer in deep layer by winter wheat in its late developing stage. Itcan also be seen from the studies that soil moisture productive efficiency has an apparenttendencyto raise sa soil moisture storage increases before sowing .This indicates that thesoil moisture reservoir has an important role in regulating water supplies to crop growthin the case of dryland farming.

采用田间试验和观测方法研究了渭北旱原东部旱作区的农田土壤水分特征和水分生产效率,结果表明,该区在麦田夏闲蓄水期(7—9月)降水量在212.7毫米以下时,1—1.2米深处存在一相对干土层,使小麦生育后期对深层土壤水分利用产生一定影响。研究还看出,旱地农田水分生产效率具有明显地随播前土壤储水量增加而提高的趋势,说明渭北旱原东部的土壤水库在旱农条件下作物供水调节中的不可代替作用。
