  • Despite the substantial changes of the spacies and the agrotechnics during the last 100 years no alteration occurred in the territorial localization of the cultivable lands of good resp. low-grade quality wheat. (CK).
  • Observations on the geography of wheat production instability
  • The article compares the instability of wheat production for all countries during the period 1956-1981. An index has been calculated for eight classes of instability. The spatial configuration of wheat production is graphically displayed

  • In this study, the temporal and spatial changes in the occurrence frequency of major meteorological disasters on wheat production were firstly explored by analyzing the observed records at national agro-meteorological stations (AMS) of China from
  • proportion of 79%. And the frequency of AMD increased significantly with climate change. Specifically, the main disasters occurred more frequently in the reproductive period than in the vegetative period. Besides, the spatial changes in the AMD frequency were
  • characterized by region-specific. For example, the wheat cultivation areas located on the Loess Plateau and the middle-lower reaches of the Yellow River suffered mainly from drought. All these results were strongly linked to climate change in China.
  • A study on moisture conditions for winter wheat and summer maize production in the Heilonggang area of Hebei Province
  • Agricultural climatology;Agroclimatology ; China ; Drought ; Irrigation ; Maize;Corn ; Precipitation ; Soil moisture ; Water resources ; Wheat
  • Winter wheat and summer maize are two important crops in the Heilonggang area which is the driest part of the North China Plain. The thermal-light conditions are satisfactory for double cropping of winter wheat-summer maize, but rainfall
  • is deficient for two crops. Wheat production in this area should be restricted to a scale which is suitable to water resources conditions, while maize production can be further developed.

  • Four agrometeorological sites located in wheat production areas, Harbin, Jinan, Zhengzhou and Chengdu were chosen to study the impact on wheat biomass with rise of temperature and CO2 concentration in many scenarios with the help of the process
  • mechanism model in the probabilistic forecasting method. The results show that the CO2 fertilization effect can compensate reduction of wheat biomass with warming temperature in a strong compensating effect. Under the CO2 fertilization effect, the rain-fed
  • and irrigated wheat biomasses increase respectively, and the increment of biomass goes up with temperature rising. The rain-fed wheat biomass increase is greater than the irrigated wheat biomass. Without consideration of CO2 fertilization effect, both irrigated
  • and rain-fed wheat biomasses reduce, and there is a higher probability for the irrigated wheat biomass than that of the rain-fed wheat biomass.

  • This article examines crop water productivity (CWP) of winter wheat and summer maize from 2003 to 2007 in the Haihe River Basin based on large-scale evapotranspiration (ET) and crop yield obtained by remote sensing technology. Results show both
  • variations in CWP of winter wheat and summer maize in most parts of the study area. They also show certain promotion potential to alleviate the water shortage. Correlation analysis of CWP, crop yield and ET shows that there is great potential for crop yield
